The new Roewe i5 is equipped with a 1.5L naturally aspirated engine, and the transmission system is matched with a 5MT or CVT gearbox. Among the five models,We recommend to buy the 1.5L automatic diamond version with a price of 84,900 yuan. The preemptive price of the new car is 76,900 yuan, and it is also the second top model of the whole department.Although the price is less than 80 thousand yuan, the configuration of this model is already very high, not only with 360 panoramic image, cruise control, electric sunroof, but also with 12.3-inch LCD instrument, and the overall configuration is very rich.

Let’s briefly review the appearance, interior design and basic parameter information of the new Roewe i5. In terms of appearance, compared with the old models, the new car adopts the parameterized Ronglin grille design with upper and lower layers. The upper grille is connected with LED headlights to stretch the visual width of the whole car, and the blackened lower grille adopts the banner design to improve the recognition of the whole car.

In terms of interior, the new Roewe i5 center console adopts asymmetric design, and the integrated hidden air outlet with yellow trim and stitching also echoes the young appearance.The new car body is slightly lengthened, powered by a 1.5L engine, with a maximum power of 88kW, a maximum torque of 150Nm and a comprehensive fuel consumption of 5.5L/100km.

What we recommend most is the 1.5L automatic diamond version.

Of the five configuration models launched this time, the first two models are all manual transmission models, so we don’t recommend them because of their poor practicability, and we don’t recommend the automatic entry model because the overall configuration is not very prominent. What we recommend most is the 1.5L automatic diamond version with a preemptive price of 76,900 yuan.

Starting price is less than 60,000 yuan, which brand-new Roewe i5 is the most worth buying-Figure 6

This model is equipped with rear parking radar, 360 panoramic image, cruise control, automatic parking, electric sunroof, keyless entry (main drive)/start and other practical configurations. In addition, the car is also equipped with 12.3-inch full LCD instrument, 10.25-inch central control large screen, car networking, full LED light group, rearview mirror heating and other configurations.

If you have high requirements on the quality of your car, you can buy a top model.It is 5,000 yuan more expensive than the 1.5L automatic diamond version.In the configuration, lane departure warning, active braking, adaptive cruise, mobile phone wireless charging, main driving electric adjustment, adaptive far and near lights and other configurations have been added. In particular, many driver assistance configurations have been added to further enhance the consumer car experience.

Summary:Even as an entry-level family car, Roewe i5 has not lowered its pursuit of quality. We can see that the new Roewe i5 can be described as a change from the inside out, with higher appearance, stronger sense of interior technology, richer intelligent technology configuration and further improved strength. Finally, according to the performance of price and configuration,What we recommend most is the 1.5L automatic diamond version.I believe its comprehensive strength is enough to satisfy the vast majority of consumers.

There is no "net" unfavorable TV series from blindly following IP to IP drama and realistic theme simultaneously

  During the National Day holiday, this newspaper published a series of reports on "Five Years of Literature and Art", which comprehensively reviewed the development of literature and art in China in the past five years. In this golden autumn season, it is sweet and long-term to taste the fruits of literature and art.

  Looking back on 2013, TV stations were completely occupied by parenting dramas led by hot moms and hot dads such as Little Dad and The Story of Hot Mom. Behind this trend is the official replacement of TV viewers: the remote control in the hands of aunts and grandmothers completely gave way to the post-80 s and post-90 s who entered the baby boom. By 2017, the audience deeply influenced by the network will become the main audience of a new generation of TV dramas. Their aesthetics, likes and dislikes, watching habits and so on have profoundly changed the appearance of Chinese opera — — Sun Li’s new work, which is being broadcasted, has changed the title of the play from the original heavy "Da Qin Yi Shang" to the present "When Flowers Bloom and the Moon Are Full" in order to pursue a sense of network.

  In the past five years, the most earth-shaking changes in the TV drama market can not be separated from a big word "net": the integration of broadcasting platforms, the network platform coming from behind in the competition for top resources, the IP of the theme network first, the sudden emergence of online dramas, the pursuit of "net sense" in aesthetic taste, and the capital of video websites making waves. In short, the Internet has become the most lively main battlefield and "big money owner" of China TV series. The drastic changes in the ecological environment have made the TV drama industry, which is carrying heavy burdens, add "new hates" such as sky-high pay, satellite broadcasting, cutout production and normalization of body double … … However, it is gratifying that the theme of realism is still strong after being washed away by the tide. Taking care of the present and focusing on the content is the people’s just need and the trump card of the market, and finally ushered in the "big year" of creation in 2017 after the ebb and flow.

  The content is that Wang Yue has become a consensus.

  In 2017, the TV series that have been broadcast on TV stations and ranked in the top position so far are as follows: to the sky kingdom, in the name of people, My First Half Life, Biography of Chu Qiao, Full Moon in that Year, Ode to Joy 2, Alliance of Military Strategists, White Deer Plain, Justices Seeker, Biography of New Condor Heroes and so on. Although the overall national drama is getting more and more expensive, the film pay is getting higher and higher, and the quality improvement is not directly proportional to it, if we put aside the huge base and compare it horizontally only from these ten or so "head" works, 2017 should belong to the "big year" of TV drama creation, regardless of the production level, the richness of theme or the degree of artistic completion.

  First of all, the ups and downs and disputes about IP dramas in the market have never stopped in recent years. After several rounds of reshuffle, such as blind speculation, crazy follow-up, survival of the fittest and so on, the attitude towards IP finally returned to rationality this year. The creative attitudes of "Sansheng Sanshi" and "Chuqiao Biography" obviously take the initiative to correct the past lessons of IP dramas — — Respect the law of traditional TV drama creation and use IP reasonably. These two dramas have created new and best achievements in the two main battlefields of daily and weekly dramas respectively, and the market income is considerable. What is valuable is that word-of-mouth has also successfully counterattacked, which has reversed the long-standing "prejudice" of public opinion on IP dramas and won many mainstream audiences who are not "fans". The boundary between traditional TV audience and "fan" audience is no longer clear.

  Secondly, this year has completely put an end to the trend of Empresses in the Palace and other big costume leading the mainstream market. Realistic works such as in the name of people, Ode to Joy 2, White Deer Plain, Justices Seeker and My First Half Life have the upper hand in the "explosion" echelon, regardless of quantity or quality. This also reflects that the core behind-the-scenes TV drama production team, after several years of impact, confusion and groping, has clarified its thinking, gained a firm foothold and strengthened the foundation of its creation in an invincible position. Looking at the rational return of the above-mentioned IP dramas and the counterattack of realism, it is not difficult to find that the integration and mutual reference of the two is the way out for both of them to adapt to the market.

  Online dramas and traditional TV dramas are more and more similar.

  Compared with five years ago, another drastic change in the TV drama market is the significant improvement in the content quality of online dramas, which has gradually bid farewell to shoddy production. Before and after 2013, the production cost of single episode of online drama was about 100,000 yuan on average. Now, the cost of single episode of 5 million+is not uncommon, and it must be said that "the production level is on par with top TV dramas and American dramas". In 2013, watching online dramas for a fee was just a "dream" for many people. Nowadays, a large number of super-customized dramas with narrow themes and the purpose of developing members emerge one after another. This summer, the two major video websites launched "Chasing the Murder in a White Night" and "Crime without a License" respectively, and both of them made a lot of money. The rise of online drama has also attracted many excellent directors, actors and production teams to join in the production of online drama. Xiaogang Feng, Hou Hongliang, Kong Sheng, Guan Hu, Zhang Li and other industry leaders are deeply involved in online drama production.

  The amazing performance of go princess go in 2016 is not unique this year. Self-made online dramas such as Chasing the Murder in a White Night, Spring Breeze is not as good as you, Crime without a license, Forensic Medicine Qin Ming and Ghost Blowing the Lamp are in full bloom. It is a popular practice to accurately locate specific groups and segment narrow themes in the market. "Suspense+"and "Youth+"are the two most popular categories, especially the former, which has a strong plot and a fast pace, burns the brain and reverses the audience’s excitement and hunger, which is very in line with the aesthetic needs of young online audiences.

  Network platforms and TV stations are increasingly integrated.

  Another major trend that cannot be ignored is that the cooperation between network platforms and TV stations is becoming more and more frequent, and the degree of integration is getting higher and higher. The standards of online drama and TV drama are becoming more and more unified. In the form of broadcasting, the linkage between network and station is becoming more and more frequent.

  What is the benchmark in this field is the dramatic changes in the weekly drama market. In 2015, the great success of "Hua Qiangu" in the summer file injected a booster into the weekly broadcast of Chinese drama. However, after only two years, Hua Qiangu seems like a lifetime ago to practitioners. This is because, on the one hand, the competition is more fierce, and it is normal for several weekly dramas to be updated simultaneously; On the other hand, the impact of network integration and other fragmented information has greatly dispelled market attention; The modes of first network, first network background, half network, half network, etc. emerge one after another, reflecting the tilt of the balance of supply and demand at any time.

  Take "Cloud of the Han Dynasty in Xuanyuan Sword" as an example. Since it was broadcast simultaneously in Shanghai Oriental TV Weekly Theater and iQiyi on August 8, it has attracted great attention from both inside and outside the industry because of the "half-network" broadcast mode. The so-called "half a network" means that the drama has been broadcast on TV for a certain number of episodes, and the remaining episodes are only broadcast on the network platform, and only paying members can watch it. In the eyes of the industry, from the previous background of the first network, the first network, and the half network to the half network today, it shows that the right to speak on the network platform is constantly increasing, and it also shows the confidence of all parties in the quality of plays and the increasing number of high-quality film and television dramas.

Promote the overall rule of law and give play to the positive role of the rule of law in the modernization of the national governance system and governance capacity.

  Promote the overall rule of law and give play to the positive role of the rule of law in the modernization of the national governance system and governance capacity.

  Supreme leader

  Adhere to the rule of law in an all-round way and consolidate the institutional foundation of China’s rule.

  The Fourth Plenary Session of the 19th CPC Central Committee made comprehensive arrangements for upholding and improving the Socialism with Chinese characteristics system and promoting the modernization of the national governance system and governance capacity. I have said many times that adhering to the rule of law in an all-round way is a remarkable advantage of Socialism with Chinese characteristics’s national system and national governance system. As the practice in Socialism with Chinese characteristics advances further, the construction of the rule of law will follow. Practice has proved that the system of national governance is systematic, normative, coordinated and stable by confirming and consolidating the fundamental system, basic system and important system of the country through constitutional laws and ensuring their implementation by using national coercive force.

  The socialist rule of law in China embodies the theoretical achievements and practical experience of our party in governing the country and is the most basic, stable and reliable guarantee for the rule of the system. To promote the overall rule of law and give full play to the positive role of the rule of law in the modernization of the national governance system and governance capacity, we should focus on the following aspects.

  First, improve the party’s ability to govern the country according to law.The constitution stipulates that the party has the overall situation and the leading position of coordinating all parties. It is necessary to further promote the party’s leadership into laws and regulations, be good at making the party’s ideas become the will of the state through legal procedures, translate them into laws and regulations, and promote the institutionalization, rule of law and standardization of the party’s leadership. Party organizations at all levels, party member and cadres should strengthen the concept of governing the country according to law and improve their ability to deepen reform, promote development, resolve contradictions, maintain stability and cope with risks by using the rule of law thinking and the rule of law.

  On March 17, 2018, the first session of the 13 th National People’s Congress held its fifth plenary meeting in the Great Hall of the People in Beijing. The Supreme Leader was elected President of People’s Republic of China (PRC) and chairman of the Central Military Commission of People’s Republic of China (PRC). This is the constitutional oath taken by the supreme leader. Xinhua News Agency reporter Ju Peng/photo

  Second, use the rule of law to ensure that the people are masters of the country.We must uphold and improve the system of people being the masters of the country, improve the system of ensuring social fairness, justice and the rule of law, ensure that the people manage state affairs, economic and cultural undertakings and social affairs according to law through various channels and forms under the leadership of the Party, and make the law and its implementation effectively reflect the people’s will, safeguard people’s rights and interests and stimulate people’s creativity.

  第三,坚持和完善中国特色社会主义法治体系。要坚持依法治国、依法执政、依法行政共同推进,坚持法治国家、法治政府、法治社会一体建设,不断完善法律规范、法治实施、法治监督、法治保障和党内法规体系,汲取中华传统法律文化精华,吸收借鉴人类法治文明有益成果,坚决抵制西方错误思潮错误观点影响,加快建设中国特色社会主义法治体系。

  第四,更好发挥法治对改革发展稳定的引领、规范、保障作用。统筹推进“五位一体”总体布局、协调推进“四个全面”战略布局,要发挥法治的引领、规范、保障作用,以深化依法治国实践检验法治建设成效,着力固根基、扬优势、补短板、强弱项,推动各方面制度更加成熟、更加定型,逐步实现国家治理制度化、程序化、规范化、法治化。

  Fifth, build a high-quality rule of law workforce.Study and plan the long-term plan for the training of rule-of-law talents and the construction of rule-of-law teams in the new era, innovate the training mechanism of rule-of-law talents, promote the balanced distribution of rule-of-law teams in the eastern, central and western regions, improve the ideological and political quality, professional work ability and professional ethics of rule-of-law teams, and strive to build a socialist rule-of-law team loyal to the party, the country, the people and the law, so as to provide a strong talent guarantee for accelerating the construction of a socialist country ruled by law.

  The comprehensive reform of judicial responsibility system is an important content of judicial system reform, which is related to judicial justice, efficiency and authority. It is necessary to do a good job in the reform task, truly "let the judges judge and be responsible by the judges", improve the judicial credibility, and strive to make the people feel fair and just in every judicial case. Strengthening the construction of rural areas ruled by law is the basic work to implement the strategy of rural revitalization and promote the comprehensive rule of law. It is necessary to educate and guide the broad masses of cadres and people in rural areas to act in accordance with the law, find ways to solve problems, solve contradictions and rely on the law, and actively promote the construction of rural areas ruled by law. It is necessary to implement the reform plan of administrative reconsideration system, optimize the allocation of administrative reconsideration resources, promote the revision of relevant laws and regulations, and give play to the institutional advantages of fair and efficient administrative reconsideration, facilitating the people and serving as the main channel for resolving administrative disputes.

  Adhere to the combination of top-level design and rule of law practice,

  Enhance the effectiveness of the rule of law to promote the modernization of national governance system and governance capacity

  The long-term goal of the rule of law construction should take into account the international and domestic situation, the process of the rule of law construction and the people’s demand for the rule of law, and coordinate with the requirements of promoting the modernization of the national governance system and governance capacity. We should constantly improve the top-level design and innovate and deepen the practice of governing the country according to law.

  With the development of the times and the advancement of reform, the modernization of state governance requires a scientific and complete legal norm system more and more urgently. On the premise of adhering to and improving the established fundamental systems, basic systems and important systems that have been proved effective by practice, we should focus on the gaps and conflicts of the legal system, make overall plans and promote the work of reforming and abolishing the release, and accelerate the establishment and improvement of the necessary legal system that is urgently needed for national governance and meets the growing needs of the people for a better life.

  Only by enforcing justice, being fair, efficient and authoritative can the effectiveness of the rule of law in state governance be truly brought into play. It is necessary to strengthen supervision over the implementation of the law, deepen the comprehensive reform of the judicial system, promote strict and standardized fair and civilized law enforcement, strive to improve the quality, efficiency and credibility of law enforcement and justice, and better transform the advantages of socialist rule of law into the effectiveness of state governance.

  The construction of the rule of law requires the participation of the whole society. Only when all the people believe in and enforce the rule of law can the country and social life truly run on the track of the rule of law. At present, some leading cadres are not good at using the rule of law thinking and methods to promote their work. The inability of leading cadres to replace the law with words and suppress the law with power is the enemy of the rule of law construction. Leading cadres at all levels must strengthen their awareness of the rule of law, take the lead in respecting the law and law-abiding usage, and set an example for system implementation. The foundation of the rule of law lies in the people. It is necessary to intensify the work of popularizing law among the whole people, carry forward the socialist spirit of rule of law, enhance the concept of rule of law among the whole people, improve the public legal service system, and consolidate the social foundation of governing the country according to law. We must adhere to the combination of ruling the country by law and ruling the country by virtue, integrate socialist core values into the rule of law, improve the long-term mechanism of honesty and credit construction, increase the punishment for behaviors such as loss of public morality and lack of honesty, and strive to form a good social trend and social order.

  More than 60 years ago, we put forward the Five Principles of Peaceful Coexistence, which have been widely recognized and supported by the international community and become the basic norms of international relations and the basic principles of international law. Since the 18th National Congress of the Communist Party of China, we have put forward the idea of promoting the building of a community of human destiny, which has been widely welcomed and highly praised by all parties and enshrined in a series of United Nations resolutions. We should take advantage of the situation and follow the trend, firmly safeguard the international order and system with the purposes and principles of the UN Charter as the core, and contribute China wisdom and China’s plan to the reform and construction of the global governance system.

  Excerpt from the speech made by General Secretary of the Supreme Leader at the third meeting of the Central Committee for Governing the Country in an All-round Way according to Law on February 5, 2020. ※.

Where did the garbage on the Yangtze River cargo ship go? —— Investigation on water pollution of cargo ships in the Yangtze River

  Xinhua News Agency, Hefei, October 17thQuestion: Where did the garbage on the Yangtze River cargo ship go? — — Investigation on water pollution of Yangtze River cargo ships

  Xinhua News Agency "Xinhua Viewpoint" reporters Dong Xue, Wang Xian and Wang Haiyue

  There are nearly 120,000 inland cargo ships in 14 provinces and cities of the Yangtze River system, with hundreds of thousands of crew members working and living on the river all the year round, which will produce a lot of pollutants such as domestic garbage, oily sewage, residual oil and chemical washing water.

  Recently, "Xinhua Viewpoint" reporters visited docks and boarded ships in many provinces along the Yangtze River, and found that some ships threw garbage into the river and directly discharged oil and sewage into the Yangtze River.

  Reporter’s visit: A ship throws garbage into the river and sewage is discharged into the Yangtze River.

  The reporter boarded a ship with a tonnage of about 7,000 tons and four crew members on board. The ship’s garbage receiving record book shows that the last time the ship received garbage was eight days ago, but strangely, there was almost no garbage on board.

  The reporter opened the three-color trash can on the boat and saw that the trash can half a person high was rice, tools and clothes, and only a few watermelon skins were in the small trash can in the kitchen.

  "Leftovers are sometimes thrown into the river." In the face of the reporter’s inquiry, the ship owner replied like this.

  When the reporter visited the docks and anchorages along the Yangtze River recently, it was found that the whereabouts of ship garbage were unknown. The reporter boarded 11 ships, and five of them were all like this — — Some have no trash cans, some use trash cans to store things, and some have not collected garbage for many days, but the trash cans are empty. The navigation routes of these ships are not fixed, and they often flow between several provinces in the middle and lower reaches of the Yangtze River.

  The Yangtze River Environmental Protection Association in a certain place has repeatedly investigated the problem of ship pollutants along the Yangtze River. A staff member of the association said, "It is common for ship garbage to be thrown into the Yangtze River. In addition to the domestic garbage on board, there are sometimes material garbage generated by freight transportation."

  The reporter found that some ships also directly discharged the sewage from their ships into the Yangtze River.

  The reporter found mysterious hoses leading to the river surface on two ships, and the surface was black and oily. The reporter entered the bilge, lit it with a flashlight, and found that the other end of the hose was buried in the oily water under the deck, and there was no depth, next to it was a small pump.

  The heads of the two ships admitted to pumping oil and sewage into the Yangtze River. "I have been engaged in shipping for more than two years, and the oily water is pumped into the river by myself, otherwise I will accumulate more?"

  Many people in the industry said that the collection and treatment of pollutants from ships in the Yangtze River is still in its infancy. According to the data of the Yangtze River Waterway Administration of the Ministry of Transport, as of the first half of 2019, there were 185 ship pollutant receiving enterprises in the Yangtze River trunk line, and only 226 ships received pollutants; There are about 100,000 ships sailing on the Yangtze River trunk line all the year round, which is equivalent to serving more than 400 ships on average for each receiving ship.

  It is understood that since the beginning of this year, only the Chongqing section of the Yangtze River has investigated and dealt with 378 illegal acts of ship water pollution, including cases of discharging domestic sewage and catering sewage during the berthing of the Yangtze River.

  Behind the pollution: the construction of receiving facilities is lagging behind and the management measures are imperfect.

  Why do these ships throw garbage into the river and discharge sewage directly into the river? According to industry insiders, this is because the construction of pollutant receiving facilities is lagging behind, and on the other hand, the relevant management measures are not perfect.

  The Law on the Prevention and Control of Water Pollution stipulates that "the people’s governments at the city and county levels where ports, docks, loading and unloading stations and ship repair plants are located shall make overall plans to build facilities for receiving, transporting, treating and disposing of ship pollutants and wastes." However, due to the lack of specific construction standards, the construction of port ship pollutant receiving facilities is seriously lagging behind.

  Many port enterprise leaders reported that there are few ports equipped with complete sets of receiving equipment in the middle and upper reaches of the Yangtze River; Most of the port areas are not connected to the municipal pipe network, and the system of receiving, transporting and disposing of pollutants from ships is not working smoothly. Urban management, environmental protection, port and shipping departments are all in charge of their own affairs, and there is no joint management force.

  At the same time, there are still some management loopholes in the collection of pollutants from ships.

  Wang Shiming, deputy director of Jiangsu Maritime Safety Administration, said that at present, the collection of ship pollutants mostly adopts market operation, and the units that have been filed by the port administrative department provide paid services. However, some ships are unwilling to accept standardized management and discharge or discard pollutants at random at non-designated receiving points; At the same time, some filing units operate illegally, charge high fees or refuse to collect garbage after charging.

  A ship owner said that many crew members had been forced to collect money but did not collect garbage. "As soon as the ship docked, a man ran to ask for money. He only carries a small bag with a list. What does he use to collect garbage? "

  Some crew members said, "To put it bluntly, 100 yuan bought a stamp on the garbage record book." They told reporters, "In some places in the middle and lower reaches of the Yangtze River, as long as you lean on the dock, garbage boats will come. Whether there is garbage or no garbage, you have to collect 100 yuan money and you can’t run away. " "80 yuan and 50 yuan, who are easy to talk, will do, 100 yuan, who is not easy to talk, and 300 yuan once!"

  The ship’s garbage record book also confirmed this problem. Some ships paid garbage fees three times in just six days because they docked at three different docks.

  The industry calls for: unified management and combination of unblocking and blocking.

  Some people in the industry and related experts suggest that to prevent pollution from ships in the Yangtze River, we should strengthen overall planning, combine dredging and blocking, improve relevant policies, and strengthen the crackdown and control of pollution.

  In recent years, some local governments along the Yangtze River are speeding up the construction of port pollutant receiving and transshipment facilities. In Yichang, Jingzhou, Anqing, Wuhu, Chongqing, Nanjing and other places, domestic sewage receiving ships and transshipment terminals have been put into use one after another.

  In order to standardize the reception and disposal of pollutants from ships, Jingzhou, Maanshan, Wuhu and other cities along the Yangtze River took the initiative to explore first, adopted the mode of government paying the bill, unified bidding, and the successful bidder received some pollutants free of charge. However, reporters visited these cities and found that most crew members said that they did not understand the relevant free policies.

  "Ships are mobile, only around the Yangtze River ‘ A game of chess ’ Unified management can manage the pollutants from ships. " Hu Shibin, president of Anhui Yangtze River Environmental Protection Association, and others suggested that the main responsibility of local governments should be strengthened, and relevant provinces and cities should set up the Yangtze River Ship Pollutant Prevention Fund according to a certain proportion to form a joint force to prevent and control ship pollutants.

  The heads of some ship pollutant receiving units called for further improvement of the government’s service purchase plan, setting assessment indicators such as public awareness, public complaints, regular inspections and spot checks, and paying fees according to the actual assessment of the winning enterprises.

  Zhang Lin, director of Wuhan Xingang Committee, believes that the monitoring of ship garbage and polluted water should be realized through technical means to improve the ability of on-site treatment and recycling. (Participating in writing: Han Wenzhe)

Although he knew that Director Lu was very busy, he promised me that he could operate on me personally … Seeing many people looking for him, he still told me patiently, which made my complicated heart calm a lot and increased my confidence in the operation. I sincerely hope that there will be more such doctors, and that will be the blessing of patients. 

◆ In May 2013, my father was diagnosed with hypopharyngeal cancer. He has been to many cancer hospitals in Guangzhou, and most of them suggested giving up medical treatment. Such bad news must have plunged us into a bottomless abyss. Coincidentally, I found Dr. Lu Yongtian. After more than 11 hours of surgery by Dr. Lu, my father got his life back. Now it’s almost a year since the operation, and my father has recovered quite well. Thank you to Dr. Lu Yongtian and his team for their kindness. I mean you. I wish Dr. Lu and his team all the best! 

◆ Hello, Director Lu! I was a patient who had a nose bridge reset yesterday. After the injury, I went to several doctors with no results. I was very anxious and afraid of being disfigured from now on. It’s you. You not only gave me positive injuries, but also gave me psychological counseling. Your noble medical ethics and kindness gave me confidence. Thank you and wish you good health and happiness! 

◆ I was able to get the help of Director Lu only because of Director Lu’s broad mind and rigorous attitude towards treating diseases. During the operation, the risk judgment of preoperative examination was verified one by one. The ruptured septal cartilage in the operation eight years ago, foreign bodies that always spread colds, nasal bone fractures caused by a close fall in the early years, and hard facial bones made the operation risks one after another. Pulling out an maxillary wisdom tooth in India two years ago kept the big doctor busy for two hours. I was so tired that I was paralyzed and sighed that my bones were hard. I’m a layman, and I can only judge by the words of an expert doctor. Director Shi Jianbo of the First Hospital of Zhongshan said that Director Lu took the doctor earlier than he did, and the operation was superb. Several experts who are respected by insiders have said that reoperation is very risky and may not be worth the loss. But without surgery, my family and work are basically at the end of the road. Director Lu successfully completed the operation with decades of skill. After eight years of suffering and depression, once I got rid of it, this is probably what the fortune teller said I would have. I will remember my kindness, work hard, study and live, sow hope, reap happiness and share joy. I wish the Department of Otolaryngology of Shenzhen Second Hospital, under the leadership of Director Lu, to rescue more patients in distress. You are the precious wealth of the country and the backbone of society. …… We really don’t know why such a doctor was killed by this!

67781621389712150

No department is a "small department"

From the time when Director Lu was chopped up to now, there are only a handful of related reports and revelations. Xiaobian has no intention to query "Otolaryngologists were chopped up" online, hoping to get more information, but he found a strange phenomenon:

27981621389712215 

I believe you can also see that many people are asking, "Why is the Otolaryngology Department a high-incidence area for medical troubles in the news? !”

In 2007, Dr. Dai Wenhong from the Department of Otolaryngology of Xinxiang Second People’s Hospital was stabbed to death. In 2011, Dr. Xu Wen from the Department of Otolaryngology, Beijing Tongren Hospital was seriously injured. In 2012, Dr. Xing Zhimin from the Department of Otolaryngology, beijing beijing People’s Hospital was stabbed and seriously injured. In 2013, Director Wang of the Department of Otolaryngology, the First People’s Hospital of Wenling, Zhejiang Province, was stabbed to death. ….. How many otolaryngologists have been hacked, stabbed and killed? It scares me, because the tragedy is far more than that! 

In professional medical forums and post bars, some netizens explained this: 

1. Nasal diseases are prone to relapse, and most of them have neurosis. If you feel uncomfortable, you think that the doctor has not given you a good opinion. 

2. Otolaryngology deals with the senses, and patients’ subjective feelings may naturally be stronger than other diseases. 3, involving sensory diseases, it is necessary to eliminate the interference of patients’ psychological problems, especially patients with mental and personality problems.

Perhaps this is just some of the causes of many tragedies, the real root, without too much explanation, we naturally understand.

In the eyes of patients, even some medical staff, otolaryngology diseases are minor diseases, and they simply don’t know the risks inside. In fact, otolaryngology mostly deals with respiratory tract, which is extremely risky. Many otolaryngologists have been chopped, stabbed and killed, which shows that patients have no correct understanding of otolaryngology at all, so it is difficult to understand once they are dissatisfied.

In the face of illness, people are too weak and fragile. In the hospital, no one is a "small department"!

Is pediatrics small? As small as the pediatrics of some hospitals are "run" by pediatric hospitals, they have to close wards and clinics, and medical staff can’t pay bonuses!

Is pediatrics big? Sure! Every family’s eye and parents’ heart are ill and they have to go to see pediatrics. This "small" clinic carries many people’s expectations!

Is dermatology small? As small as some top-three hospitals, the dermatology department only looks at eczema, allergies and boils for one year.

Dermatology University? As big as a herpes zoster, it can torture you for life!

Please, don’t say which department is a small department in the future. It doesn’t matter. This view will subtly affect patients, and I wonder how many doctors will be killed or injured. "Director Lu is now out of danger", but what about the follow-up? Where did it hurt? Will it affect his medical career? We continue to pay attention.

Xiaomi SU7 racetrack is a thrilling scene, and the safety of electric vehicles running on the racetrack attracts attention.

Recently, a video broke out on the Internet, and Xiaomi SU7 (parameter | inquiry) rushed out of the track and hit the guardrail while driving at the tianmashan circuit. According to the account of the parties on social media, the brakes of the vehicle were suspected to be attenuated before turning, but fortunately, the accident was not serious, the body structure was still intact and the people on board were safe and sound. Because the vehicle in this accident is Xiaomi SU7, which has just been listed, it has aroused great concern and extensive discussion on the Internet, and there are also different opinions on the cause of the accident. So how did all this happen?

● How about visual safety? The accident was minor, the car was not damaged, and the personnel were safe.

First of all, let’s talk about safety. From the live video and pictures, we can easily see that the impact of the vehicle is not strong, and the thick tire wall is set on the outside of the corner, and the buffer area is large enough, so the main part of the car body can’t see any signs of deformation after the accident, and the four doors are almost unaffected. This is a minor accident on the track. If the collision impact is greater, the test of the strength of the body of Xiaomi SU7 has just begun.

Home of the car

However, the passive safety design of Xiaomi SU7 car body is fairly comprehensive. The whole car adopts a cage-type steel-aluminum hybrid car body. The proportion of high-strength steel and aluminum alloy reaches 90.1%, and the torsional stiffness reaches 51,000 nm/deg, which is higher than that of the super sports car Bugatti Veyron (50,000 nm/deg). The battery beam and sill beam are made of 2000MPa ultra-high strength steel and ultra-wide multi-cavity extruded aluminum alloy, respectively, which can withstand the lateral impact up to 820kN.

We guess the cause of the crash.

Accidents that rush out of the track in corners are not uncommon, and there are many reasons, which may be caused by the driver’s improper operation and missing the braking point. Of course, some reasons of the vehicle itself are not excluded. As for whether there is a problem with the personnel factor or the vehicle’s braking system in this accident, we dare not jump to a conclusion until we have more information and an appraisal report issued by an authoritative organization. Aside from the driver’s improper operation, what factors may lead to the accident if we only explore the vehicle itself?

1. The driver is not familiar with the vehicle performance and misjudges the braking point.

In terms of power output, the motor has high energy conversion rate, greater torque, and can output peak torque at the beginning of starting, which has inherent advantages in acceleration performance. Therefore, in tianmashan, a track with many bends and few straight roads, driving pleasure is higher than that of oil trucks. Xiaomi SU7 Max version is equipped with dual-motor four-wheel drive system, with amazing power parameters, and the officially announced acceleration time is only 2.78 seconds. However, compared with oil vehicles, electric vehicles also have an obvious disadvantage, that is, weight.

Home of the car

The curb weight of Xiaomi SU7 Max is as high as 2.2 tons. Even for BBA with four-wheel drive vehicles of the same level, their curb weight is mostly between 1.9 and 2.0 tons. The continuous high-load track conditions are a great test for the braking system of electric vehicles. At the same time, it should be noted that the delivery of Xiaomi SU7 was only started at the beginning of this month. Today, the time for users to get a new car is not long, and they are not familiar with the performance of the vehicle. There is a possibility that the brake point will be misjudged directly off the track.

2. iboost’s Feet in Extreme Working Conditions

Xiaomi SU7 is equipped with Bosch DPB2.0 Decoupled Power Brake)+ESP10.0, which is a fully decoupled brake-by-wire scheme. The brake pedal and the brake system are not driven by the traditional mechanical scheme of brake pedal-vacuum booster-brake master cylinder-oil pressure. As the name implies, full decoupling means that there is no mechanical connection between the brake pedal and the brake, and the brake pedal is only responsible for inputting pressure signals, and the electric control system exerts pressure on the brake. If a node of the above link fails, it is possible that the situation mentioned in the chat record will happen. But before the inspection information of no authoritative organization is released, the above is just speculation.

● How is Fe racing solved? The high-power kinetic energy recovery system can almost replace the brake.

So for electric vehicles, how to deal with the track conditions? Let’s take a look at how the electric Formula FE racing car is made. In addition to the top-notch braking system, braking heat dissipation efficiency, aerodynamic design and special tires, it is also equipped with a kinetic energy recovery system called ERS(Energy Recovery System), which is installed in F1 racing cars (KERS), electric Formula FE racing cars, Le Mans and other racing cars. Take the electric Formula FE racing car as an example. At present, the ERS system of the third generation FE racing car adds a 250kW front motor for kinetic energy recovery on the basis of the original 350kW rear drive motor of the second generation racing car.

● High-performance tram solutions in the industry: the maximum kinetic energy recovery power has risen to 400kW.

In the field of civil high-performance electric vehicles, besides strengthening the hardware of braking system, optimizing braking heat dissipation efficiency, aerodynamic design and using tires with stronger performance, kinetic energy recovery system can also play a certain role in vehicle deceleration. Take the Porsche Taycan Turbo GT (New North’s score of 7:07:55), which has set the fastest lap time in New North, as an example, the maximum energy recovery power of its kinetic energy recovery system is increased by more than 30%, from 290kW to as high as 400kW. However, although the kinetic energy recovery system can play a certain role in reducing the speed and braking distance, it is far from enough to rely on the kinetic energy recovery system to deal with the extreme track conditions.

Low article summary:

Generally speaking, although the runaway brake incident of Xiaomi SU7 track exposed some problems of Xiaomi’s driving on the track, it also provided us with an opportunity to observe and think about the safety problems of the automobile industry. From this incident, we can see that the safety of electric vehicles in the track depends not only on the design and manufacture of vehicles, but also on the driving skills and habits of users. In order to make mass-produced sports cars play their strongest performance on the track, it is also necessary for all parties, such as automobile brands and users, to work together. Of course, this incident has also brought improvement experience and lessons to Xiaomi Company, and also has a positive effect on new product development.

What conditions does China need to cut interest rates next?

Core view

In the second quarter, the three conditions of interest rate reduction may have marginal changes, which in turn will push interest rates down. (1) According to the market expectation, the Federal Reserve may start to cut interest rates in June, and the domestic wide monetary space may be gradually opened. (2) At present, domestic real estate investment and sales are still in a deep adjustment range. In the first quarter, the financial strength was less than expected, the issuance of special bonds was slow, the growth rate of infrastructure may be restricted, and the weak economic fundamentals may need further care from the broad currency. (3) From a medium-and long-term perspective, in the process of resolving local debt risks, for the needs of steady growth and reducing the cost of bond swap, or the cooperation of the central bank with a wide currency, and the real estate cycle has not yet reached an equilibrium level, the wide currency is still needed for support. Under the combination of "wide currency+weak fundamentals", interest rates may usher in new catalysis.

abstract

Since the first quarter, the interest rate of 10-year treasury bonds has continued to consolidate after falling to around 2.3%.It is difficult for the interest rate to exceed 2.3% in the short term, mainly because of the following two reasons: 1) The interest rate of 1)10Y national debt has implied the expectation of 20BP interest rate reduction, but at present, under the restriction of exchange rate, the probability of short-term interest rate reduction in China is low; 2) On the economic fundamentals, most macro data in January and February were better than expected, and the bond market was adjusted back due to the recovery of sentiment in the equity market and the seesaw effect of stock and debt. If the subsequent interest rate is to go down further, it may need the guidance of MLF to cut interest rates. What are the conditions for the next rate cut? We answer this question from overseas, domestic and medium-and long-term perspectives.

Condition 1: the exchange rate restricts interest rates and waits for the Fed to cut interest rates.

The exchange rate and interest rate have once again reached their respective low levels, and the supervision faces a dilemma, or it may need to wait for the Fed to cut interest rates.There are two main reasons for the recent depreciation of the RMB exchange rate: 1) In 2024, the resilience of the US economy is still strong, which is manifested in the stubbornness of inflation and the resilience of employment, and the Fed’s interest rate cut is expected to be delayed. Judging from the bitmap of the interest rate meeting in March and the expectations of the futures market, the Fed may cut interest rates at least three times in 2024 and start to cut interest rates as early as June. 2) In addition, in the early period, the Bank of Japan’s monetary policy turned, and the exchange rate of the yen was favorable, and the yen depreciated. As the second largest weight in the basket of currencies of the US dollar index, the yen led to the appreciation of the US dollar and the passive depreciation of the RMB.

Condition 2: The economy still has hidden worries, and it still needs wide monetary care.

1-2Most macro indicators in June were better than expected, but the performance of high-frequency indicators such as real estate and infrastructure was still weaker than the same period of last year, which needed the care of a wide currency.In January and February, most macro indicators such as CPI, industrial added value, investment in fixed assets, export and consumption were better than expected, but credit indicators such as social financing were lower than expected, and high-frequency indicators in real estate, infrastructure and other fields were still weaker than the same period of last year. Specifically, 1) although real estate investment converged to -9% in January and February, other related indicators of real estate (such as newly started area and sales area) are still in the double-digit decline range; 2) The growth rate of infrastructure investment in January and February was at a high level of 9%, but the rate of construction site resumption after the holiday was weaker than that in the same period of last year. The issue of special bonds and the net financing of urban investment bonds in the first quarter were not optimistic, and the growth rate of subsequent infrastructure may slow down.

Condition 3 of interest rate reduction: to solve the two major risks, it is also necessary to cooperate with a wide currency.

Looking back at history, risk resolution needs substantial support from liquidity.For example, during the period of 2015-2018, in order to cope with local hidden debts and high inventory of real estate, China issued a total of about 12 trillion replacement bonds, 2.65 trillion new special bonds, and 3 trillion net PSL, with a total scale of nearly 18 trillion, which is about 26% of GDP in 2015. At the same time, the one-year LPR quotation was reduced by 120BP.

Risk 1: In the process of localized debt, infrastructure investment may be under pressure, and the pressure of debt service will rise, which requires the cooperation of a wide currency.Under the current background of localized debt, the expansion of local debt, especially implicit debt financing, may be restricted. From the perspective of capital correlation, local implicit debt has the greatest impact on the growth rate of infrastructure. In 2024, infrastructure investment may be under pressure, and from the perspective of steady growth, it still needs the support of a wide currency. In addition, from the perspective of interest payment pressure, the balance of government debt is expected to increase by 13% in 2024, while the growth rate of generalized fiscal revenue and expenditure in 2024 is only 2.5% and 7.9%. In the case of no obvious decline in interest payment cost, the pressure of government interest payment may rise further. From the perspective of reducing the pressure of government debt repayment, it is necessary to cooperate with a wide currency.

Risk 2: the downward pressure on real estate is still great, and it needs wide currency support.Judging from the scale of real estate investment, the scale of China’s real estate investment in 2023 decreased by nearly 25% compared with the high point in 2021, while Japanese real estate investment peaked in 1996, with the highest cumulative decline of 54%. From the perspective of housing price, the price index of new houses and second-hand houses in 70 cities in China has fallen by about 5% and 10% respectively compared with the high point in 2021, while the average residential land price index in Japan has fallen by 47% compared with the high point. Judging from the level of residents’ leverage ratio, China’s residents’ leverage ratio is still consolidating, while Japan’s residents’ leverage ratio started rapid deleveraging in 1999, with the maximum leverage ratio of 12.6pct. To sum up, at present, the downside risk of China’s real estate is still large, which requires the support of a wide currency.

The following is the text

Since the first quarter, the interest rate of 10-year treasury bonds has been rapidly falling to around 2.3%, and it has continued to consolidate in the near future.It is difficult for the interest rate to exceed 2.3% in the short term. We believe that there are two main reasons: (1) Compared with the one-year MLF interest rate of 2.5%, the interest rate of 10-year government bonds has implied the expectation of interest rate reduction of 20BP. However, under the restriction of exchange rate, the Federal Reserve will not budge, so the probability of short-term interest rate reduction in China is low, and it may be difficult for interest rates to fall sharply again; (2) On the economic fundamentals, the macro data in January and February were disclosed one after another, among which the export, CPI, investment in fixed assets, industrial added value and other indicators were all better than expected, and the bond market rebounded due to the recovery of sentiment in the equity market and the seesaw effect of stock and debt. If the subsequent interest rate is to go down further, it may need the guidance of MLF to cut interest rates.

What are the conditions for the next rate cut? We answer this question from overseas, domestic and medium-and long-term perspectives.

Exchange rate and interest rate once again came to their respective low levels.Since the "811" exchange rate reform in 2015, the stages when the exchange rate and interest rate are at their respective relatively low levels are mainly from the end of 2016 to the beginning of 2017 and the beginning of 2020. The follow-up trend of the two stages is the upward trend of interest rate and the appreciation of exchange rate. The essential reason behind this is the improvement of economic fundamentals. However, at present, the domestic economy is still in a weak recovery stage, and the expectation of the Federal Reserve’s interest rate cut is delayed, so the supervision faces a dilemma between exchange rate and interest rate.

Is the American economy "soft landing" or "reflation"? When will the interest rate cut come?

The market had expected that the Federal Reserve would start to cut interest rates in the first quarter of 2024. In this regard, the US bond interest rate was expected to cut interest rates in advance and fell sharply in the fourth quarter of 2023; However, the recent expectations of the Federal Reserve to cut interest rates have been frustrated, and the interest rate of US bonds has also rebounded. The reason behind this is that the US economy is still resilient, which is manifested in the stubbornness of inflation and the resilience of employment.

From more perspectives: 1) American inventory cycle is at the bottom, and some industries such as retail and wholesale show signs of replenishment; 2) From the perspective of industry prosperity, both manufacturing and non-manufacturing PMI are at the bottom, and the consumer confidence index is obviously picking up. As the economy continues to exceed expectations and inflation is sticky, the market’s expectations for the US economy have shifted from a soft landing to re-inflation.

Cut interest rates at least three times in 2024, and cut interest rates as early as June. Judging from the bitmap of the interest rate meeting in March, the Federal Reserve expects to cut interest rates three times (25 BP each time) in 2024; Judging from the expectation of CME futures market, the market expects the Fed to cut interest rates as early as June. As the Federal Reserve starts to cut interest rates, the pressure of RMB exchange rate depreciation will be reduced, and the domestic wide monetary space will also be opened.

In addition, the shift of the Bank of Japan’s monetary policy in the previous period led to the depreciation of the yen and the appreciation of the US dollar, which is also one of the reasons for the recent depreciation of the RMB exchange rate. On March 19th, the Bank of Japan announced the adjustment of the monetary policy framework, decided to raise the short-term policy interest rate from -0.1% to 0-0.1%, and cancelled the yield curve control policy (YCC), and will guide the short-term interest rate as the main policy tool in the future. The yen’s exchange rate trading was full of benefits and depreciated rapidly after the monetary policy turned. As the second largest weight in the basket of currencies of the US dollar index, the depreciation of the Japanese yen makes the US dollar appreciate and the RMB passively depreciate.

1-2Most domestic macro indicators were better than expected in June.Judging from the data of the opening year, most macro indicators in January and February were better than expected, such as CPI of 0.7% (expected 0.4%), cumulative industrial added value of 7% (expected 4.3%), cumulative investment in fixed assets of 4.2% (expected 3%), cumulative social zero of 5.5% (expected 5.4%) and export (denominated in US dollars). However, credit indicators such as social financing were lower than expected. For example, in February, social financing increased by 1.5 trillion yuan (expected 2.4 trillion yuan) and the stock of social financing increased by 9% year-on-year (expected 9.1%).

However, some macro indicators deviate from micro high-frequency indicators, especially in the fields of real estate and infrastructure.From the perspective of high-frequency indicators, high-frequency indicators such as rebar output, cement delivery rate, cumulative transaction area of residential land in 100 cities and cumulative transaction area of commercial housing in 30 cities are still lower than the same period in 2023.

Specifically:

oneAlthough real estate investment converged to -9% in January and February, other related indicators of real estate are still in the double-digit decline range.In January and February, the newly started, constructed and completed housing areas were -31%, -11% and -21% respectively compared with the same period of last year. The national commercial housing sales area and sales volume were -25% and -32% respectively, and the real estate investment end and sales end were still in deep adjustment.

2From January to February, the growth rate of infrastructure investment (including electricity) was at a high level of 9%. However, judging from the situation of project resumption, the rate of post-holiday construction site resumption was weaker than that of the same period last year.According to the survey and statistics of Centennial Construction Network, as of March 12th, the rate of starting and returning to work and the rate of working on labor services in national construction sites were 75.4% and 72.4% respectively, which were 10.7pct and 11.5pct; lower than that in the same period of the lunar calendar in 2023. From January to February, the investment amount of the project also dropped by more than 40% compared with the same period of last year.

In addition, from the perspective of project funds, the current high growth rate of infrastructure may mainly come from the support of the trillion-dollar issuance of government bonds in 2023, but the situation of funds in the first quarter, especially special bonds and urban investment bonds, is not optimistic.

Credit funds increased slightly:In January-February 2024, the medium-and long-term loans of newly-added enterprises were 4.6 trillion yuan, 10 billion less than that of the same period of last year. If the proportion of medium-and long-term loans invested in infrastructure in January-February 2023 and January-February 2024 is estimated by using the proportion of medium-and long-term loans invested in infrastructure in Q1 2023 and 36% in the whole year of 2023 respectively, it is estimated that 167 billion yuan will be invested in infrastructure in January-February.

The issuance of new special bonds is slow:From January to March, 2024, a total of 634.2 billion new special bonds were issued, 722.6 billion less than the same period of last year, and the issuance progress was slow. Among them, the proportion invested in infrastructure (excluding infrastructure construction of municipal and industrial parks) is about 35%, which is slightly higher than the proportion invested in infrastructure in Q1 2023 (about 34%). The scale of special debt invested in infrastructure in January-March was about 237.9 billion less than that in the same period of last year, with a year-on-year growth rate of about -52%.

The net financing of urban investment bonds has been reduced:From January to March, the net financing of urban investment bonds was only 166.1 billion, a year-on-year decrease of 481.6 billion, with a year-on-year growth rate of -74%.

Generally speaking, the performance of domestic real estate is still weak, and infrastructure investment may also weaken under the background of localized debt. M1, the price level continues to run at a low level, and it still needs the active care of the wide currency to promote its low level recovery.

Looking back at history, risk resolution needs substantial support from liquidity.

During 1998-2004, faced with the impact of the Asian financial crisis and the high non-performing loan ratio in the banking industry, fiscal policy, on the one hand, issued a total of 210 billion treasury bonds for three consecutive years to expand government investment, on the other hand, issued 270 billion special treasury bonds to replenish bank capital. The total scale of the two debts accounted for 5.6% of GDP in 1998, and at the same time, monetary policy was greatly relaxed, and the one-year loan interest rate was reduced by 306BP.

During 2015-2018, the regulatory authorities actively solved the problem of hidden debts of local governments by "opening the front door and blocking the back door", and issued a total of about 12 trillion replacement debts, which made the local hidden debts explicit and gave local governments the right to issue bonds. During the period, they issued a total of 2.65 trillion new special debts. In addition, the regulatory authorities also realized the goal of real estate destocking through the monetization of shed reform, with a cumulative net investment of about 3 trillion PSL funds. The total scale of these funds is as high as nearly 18 trillion, which is about 26% of GDP in 2015. At the same time, monetary policy has remained loose during this period, and the one-year LPR quotation rate has been reduced by 120BP.

In 2023-2024, in the face of local debt risks and the downturn of the real estate cycle, it is estimated that 7.7 trillion yuan of new local special bonds will be issued, 1.5 trillion yuan of special refinancing bonds will be issued, 1 trillion yuan of additional government bonds will be issued, and 1 trillion yuan of special government bonds will be issued, and the accumulated PSL funds will be about 0.25 trillion yuan, totaling over 11 trillion yuan, which is about 9% of GDP in 2023. Since 2023, the one-year LPR quotation rate has been reduced by 20BP.

2024In 2006, we continued to face two major risks: local debt and real estate downturn. In the process of resolving the two major risks, we also need the cooperation of wide currency.

Risk 1: The local government debt pressure may still rise, which should not be underestimated.Compared with 2022, in 2023, the debt ratio of all provinces rose to varying degrees, among which the debt ratio of 12 high-risk areas was generally high and rose rapidly. In 2023, only the debt ratio of Beijing, Shanxi, Jiangsu, Shanghai and Xizang was within the warning line of 120%. In 2024, the scale of local special debt will still increase, but the pressure of local fiscal revenue is still there, and the debt pressure may continue to climb, and localized debt has a long way to go.


Risk 1: Under the background of debt conversion, infrastructure investment may be under pressure.
Judging from the document "Measures for Strengthening the Management of Government Investment Projects by Classification in Key Provinces (Trial)" issued by the General Office of the State Council, the key debt-oriented provinces will strictly control the new government investment projects and strictly clean up and standardize the government investment projects under construction before the local debt risk drops to a medium or low level. Judging from the investment plan of major projects, the investment amount of key projects in 2024 in Inner Mongolia, Guangxi, Guizhou, Ningxia and other key debt-paying provinces and cities decreased significantly compared with that in 2023.

Risk 1: Infrastructure investment may be under pressure, and stable growth requires a wide currency.Under the current background of localized debt, the expansion of local debt, especially the financing of implicit debt, may be restricted, and from the perspective of capital correlation, local implicit debt has the greatest impact on the growth rate of infrastructure. At present, the proportion of hidden debts and infrastructure in 12 provinces is about 19% and 26%. In 2024, if the growth rates of hidden debt and infrastructure in 12 provinces are -5% and -5% respectively, and the growth rates of hidden debt and infrastructure in non-12 provinces are 8% and 10% respectively, the corresponding annual growth rates of hidden debt and infrastructure are 5.7% and 6.1% respectively.

Risk 1: the pressure of interest payment is rising, and wide finance also needs the cooperation of wide currency.In addition, from the pressure of interest payment, the interest payment expenditure of government bonds reached 1.9 trillion in 2023, accounting for 6.7% and 5.1% of the general fiscal revenue and expenditure, up by 0.4 and 0.3pct; year-on-year; In 2024, the balance of government debt is expected to increase by 13%, while the growth rate of generalized fiscal revenue and expenditure in 2024 is only 2.5% and 7.9%. Under the condition that the cost of interest payment has not decreased significantly, the pressure of government interest payment may further rise. Judging from the rhythm of bond issuance, the issuance of government bonds will start in May or will enter a peak period; Judging from the maturity of bonds, it is estimated that about 10 trillion government bonds will mature in 2024, which means that if the interest payment cost of new bonds after bond swap is reduced by 1BP, the interest payment will be saved by 10 billion. From the point of view of reducing the pressure of government debt repayment and reducing the cost of bond swap, wide finance needs the cooperation of wide currency.

Risk 2: Is the downside risk of real estate over? From the perspective of quantity.

From the perspective of housing demand,According to the calculation of Oriental Jincheng, the sales area corresponding to the demand for new housing in cities and towns in 2021-2025 is about 718 million square meters. Suppose that the center of China’s real estate sales area is about 1 billion square meters. Although the sales area of China’s real estate is close to the center level at this stage, the sales area of real estate above the center in the past decade or so has overdrawn some of the housing demand in subsequent years, and this part of the real estate bubble may take a long time to clear up.

Judging from the scale of real estate investment,In 2023, the scale of China’s real estate investment was about 11 trillion yuan, which was nearly 25% lower than the high point in 2021. Judging from Japan’s experience, Japan’s real estate investment peaked in 1996, and now it is stable at about 18 trillion yen, with a cumulative decline of nearly 40% from a higher point and a maximum cumulative decline of 54%.

Risk 2: Is the downside risk of real estate over? From the perspective of price.

From that perspective of house price,According to the data of Zhongyuan Real Estate, by the end of 2023, the prices of second-hand houses in Beijing, Shanghai, Guangzhou and Shenzhen had dropped by 17%, 19%, 18% and 31% respectively. The price index of new and second-hand houses in 70 cities disclosed by the Bureau of Statistics peaked in August 2021, and by February 2024, it had dropped by about 5% and 10% respectively. From the experience of Japan, the average residential land price index in Japan reached a high point in 1991, and then declined all the way. In 2023, the average residential land price index has fallen by 47% from a high point.

Residents’ income confidence is weak, and the expected decline in house prices accounts for a relatively high proportion.In addition, according to the results of the central bank’s questionnaire survey, in the fourth quarter of 2023, only 12.6% of residents thought that their income had "increased", down 1.2 percentage points from the previous quarter, and the residents’ confidence index for future income further fell to 47%; From the perspective of house price expectation, only 12% residents expect house prices to rise, while 20.2% residents expect house prices to continue to fall.

Risk 2: the downward pressure on real estate is still great, and it needs wide currency support.

Japan’s untimely policy response is one of the reasons why it has been lost for 20 years.The Economic White Paper issued by the Planning Department of Japan in 1992 holds that "the economic slowdown that began at the end of 1990 was mainly due to the influence of preventive monetary tightening and self-adjustment in the process of maintaining economic balance"; It was not until 1993 that the Japanese government realized that this economic downturn was different from the previous economic recession cycle. Japan’s discount rate changed from tight to loose in July 1991 and began to cut interest rates. In September 1993, the discount rate fell to 1.75%, which was lower than the lowest interest rate before the bubble burst, but it did not stop the downward trend of the real estate cycle. However, Japan’s land policy, which was tightened in the early stage, was not abolished until 1998. However, at this time, the impact of the bursting of the asset bubble on the behavior of residents and enterprises has been difficult to easily reverse, and the Japanese economy has fallen into a lost twenty years.

Judging from the leverage ratio of residents,The leverage ratio of Chinese residents has been consolidating at around 62% since it reached a high point in 2020; From the experience of Japan, after the bursting of the Japanese real estate bubble in 1990, the leverage ratio of Japanese residents was consolidating for a period of time. In 1999, it started rapid deleveraging and bottomed out in 2007, with a deleveraging rate of 12.6pct.

Generally speaking, the downside risk of China’s real estate industry may not be over yet, and it still needs the support of a wide currency.

In the second quarter, the above three factors may have marginal changes, thus pushing down interest rates.(1) From the market expectation, the Federal Reserve may start to cut interest rates in June, and the domestic RRR cut space may be gradually opened. (2) At present, domestic real estate investment and sales are still in a deep adjustment range. In the first quarter, the financial strength was less than expected, the issuance of special bonds was slow, the growth rate of infrastructure may be restricted, and the weak economic fundamentals may need further care from the broad currency. (3) From a medium-and long-term perspective, in the process of resolving local debt risks, for the needs of steady growth and reducing the cost of bond swap, or the cooperation of the central bank with a wide currency, and the real estate cycle has not yet reached an equilibrium level, the wide currency is still needed for support. Under the combination of "wide currency+weak fundamentals", interest rates may usher in new catalysis.

Xiaoxian County, Anhui Province: The county party secretary "falls off the horse" and the government building of over 100 million yuan is unfinished.

On July 11th, 2014, in Xiaoxian County, Suzhou City, Anhui Province, the new building of the county government was vacant and abandoned. The Paper Yang Yi map

        If nothing happens, the civil servants in Xiaoxian County, Anhui Province are now sitting in luxury office buildings in the new city. Who would have thought that the former county party secretary’s bribery "falling horse" not only put himself in prison, but also made the new government building that was about to be completed an unfinished building.

        At the end of 2009, Xiaoxian county began to build a new administrative district on the north side of the county. In 2012, the main project of the new government office building group with an investment of over 100 million yuan and a construction area of over 70,000 square meters was basically completed. When all government agencies and units were about to settle in, the then county party secretary, Bao Baoliang, fell.

        His downfall has touched the whole body: dozens of party and government cadres in Xiaoxian County have been implicated, and the project of the new government affairs district has been stranded so far, and no one dares to move in.

The "county building" that has been built.

        Xiaoxian county is located in the northernmost part of Anhui province, at the junction of Jiangsu, Shandong, Henan and Anhui provinces, with an area of 1885.3 square kilometers and a population of 1.436 million. In 2013, the per capita net income of farmers was 8063 yuan.It is a national poverty-stricken county. By the end of 2010, the county government’s related debt was about 720 million yuan..

        In April and July, 2014, The Paper (www.thepaper.cn) went to Xiaoxian for field interviews twice.

        Located in the new administrative district in the northeast of the county, it is about 2 kilometers away from the county government. There is a quiet big construction site on the north side of Shunhe Road. There are 4 or 5 buildings on the east and west sides of the construction site respectively, and there is a magnificent building in the middle. And the middle area of these buildings is full of mounds and weeds.

        The central building is gray, the main part has been completed, and the interior has not been renovated. The building is divided into five parts, and the main building in the middle has six floors. There is also an annex building in its northeast, southeast, southwest and northwest corners, each with five floors.

        There is no project overview board near the construction site, but there is a project overview board of "Landscape and Road Project of Xiaoxian Government Square" in the building. The overview card shows that the project covers an area of 57,700 square meters, with a total investment of 22.9 million yuan. The commencement date is July 15, 2012, but the completion date is blank.

        The Paper found that there was not a construction worker in the whole building, and there were no building materials in and around the building. In a room on the second floor, there lives a site caretaker, who has been guarding the square project in front of the door for two years. Every day when he arrives at dinner, he goes home for dinner, then comes back and sleeps in the building at night.

        According to master Zhu Hailiang, who lives in Xiaozhuzhuang, south of the construction site, this building is a new office building of the county government, but it has not been settled yet because it is not allowed to move. "This building is called Anliang Building. It has been built for two years and has not been moved since." Zhu Hailiang said that he used to open a small shop on the construction site and cook for the workers.

        According to public information, the full name of Anliang Building is "Anliang Yubei Building", which was built by Anliang Real Estate Co., Ltd. (hereinafter referred to as Anliang Real Estate) and started construction in the government affairs new district on November 22, 2009; The building has a total construction area of 23,966 square meters, which is divided into five parts: main building, 1# building, 2# building, 3# building and 4# building.

        However, the staff of Anliang Real Estate Office said: Anliang Group does not have a building in northern Anhui, and everyone has not heard that Anliang Real Estate has a building in northern Anhui in Xiaoxian County. The insider said that the building is the office building of the county party Committee, the county government and the county people’s congress, and it has been in a state of suspension in the second half of 2012.

        Why is the government building called "Anliang Wanbei Building"?

        According to an article published on the website of Anliang Real Estate on December 23, 2009, the company has established a close strategic partnership with Xiaoxian government and has been engaged in the construction of Xiaoxian New Town. Not only Anliang Wanbei Building was built by it, but also the county experimental primary school and county people’s hospital were built by Anliang Group, and some roads in the new city were also invested by Anliang Group.

        The leaders of some committees and bureaus in Xiaoxian once told China Sankei Shimbun that,The new government office building group was built by backdoor, and was built by Anliang Real Estate through land replacement.

The "eight overall situations" of the same shutdown

        Zhu Hailiang pointed to the nine buildings on the south side and said that they are the "eight overall situations" of the county. Except for a white building that has just been completed, the rest of the buildings have been shut down for at least one year.

        The Paper found that some main parts of these nine buildings have been completed, and some are red brick walls, which are wrapped by steel bars. Without exception, there are no workers in the construction, only a few masters who look after the construction site.

        In a small board room on the construction site, Master Ding told The Paper that there are eight county-level administrative units, collectively referred to as the "eight overall situations"; In addition, there is another building which is an exhibition hall.

        Master Ding said that he has been in charge of the construction site of the Industrial and Commercial Bureau for three years, and it has been half a year since he came. Since then, other buildings have started construction one after another. The latest building was the Judicial Bureau, which started construction in June 2013.

        At present, these nine buildings have been shut down. "The building of the Industrial and Commercial Bureau built a wall in 2013, and it was not covered at all in 2014." Master Ding said that all the workers have left, even the contractor has left.

        The plan next to the construction site shows that the location of the "Eight Overall Situations" is the "Central Square" project. The project has a total land area of 124,943 square meters and a building area of 14,476 square meters. There are 10 buildings in total, which are Agriculture Committee, Grain Bureau, Commerce Bureau, Water Conservancy Bureau, Price Bureau, Archives Bureau, Culture and Information Committee, Statistics Bureau, Health Bureau and Education Bureau, with a total building area of 47,818 square meters.

Talk about the new government building that turns pale with fear

On July 11, 2014, in Xiaoxian County, Suzhou City, Anhui Province, a man rode by the county government of Xiaoxian County. This is a building.Four-story old office building in the old city.  The Paper Yang Yi map

        Today, four teams, including Xiaoxian County Party Committee and County Government, all work in the four-story old office building in the old city. A pillar in the courtyard of the county party Committee says that the office building of the county party Committee was completed in 1994.

        Not long ago, The Paper came to the Propaganda Department of Xiaoxian County Committee and offered an interview on the new government building. After reporting to the leaders, Wang Heng, director of the Foreign Publicity Office, said: "There is no government building. If there is, it has been terminated."

        When The Paper asked questions again, Wang Heng said with a smile, "There is no such thing now. We are doing a good job here. It is very old and simple, which conforms to the central policy."

        When the reporter suggested that the propaganda department should coordinate the interview with the development and reform commission, housing construction and other departments, he refused.

        The Paper visited the Urban and Rural Planning Bureau, the National Development and Reform Commission and other departments. A staff member of the Planning Bureau said that the shutdown of the building in northern Anhui was due to the policies and regulations on the construction of national buildings, but they were not clear about the specific planning of the new government affairs district.

        Ma Lin, deputy director of Xiaoxian County Development and Reform Commission, said that it was not clear that he had just taken charge of this work. He said that he could not provide relevant project approvals on the grounds that the staff familiar with the situation in the project department were on a business trip.

        According to a staff member of Xiaoxian Project Department of Anliang Real Estate, Wanbei Building was built for the government, but the specific situation is not known.

        The Paper looked up the public information and found that the new administrative center in Xiaoxian County (Wanbei Building) only had the bidding or bid-winning announcements for the main project, building construction supervision, interior and exterior decoration engineering and building ventilation engineering, but there was little public information for the "eight overall situations" projects such as the Agriculture Committee and the Water Conservancy Bureau.

        It is doubtful whether these government buildings have been approved by the competent authorities. In addition, the specific cost of the project is not known to outsiders.Everyone interviewed by The Paper said that the cost of the new government buildings must exceed 100 million yuan, some said it was more than 100 million yuan, and some predicted it would exceed 200 million or 300 million yuan.

The new office building ran aground because of the fall of the county party secretary

On July 11, 2014, in Xiaoxian County, Suzhou City, Anhui Province, the abandoned new government office building was covered with weeds.  

The Paper Yang Yi map

        Since the government building with such a large area was built, why did it stop halfway?

        Just when the The Paper reporter went to Xiaoxian for an interview in April this year, Yang Wenya, then director of the Foreign Affairs Office of the Propaganda Department of the County Party Committee, told The Paper that the old government building and the county party building in Xiaoxian had been in disrepair for a long time, and the government decided to build a new building; In May 2012, the main project of the new government building was completed, and it is expected to move into the office in July of that year.

        Unexpectedly, in July 2012, the former county party secretary, Bao Baoliang, was removed from the positions of director of the Xiaoxian People’s Congress Standing Committee and secretary of the county party Committee for alleged corruption and bribery. At the beginning of December 2012, the CPC Anhui Provincial Commission for Discipline Inspection announced that Wu Baoliang, the former county party secretary of Xiaoxian County, Anhui Province, had been investigated and punished for serious violations of the law.

        According to public reports, on February 24, 2014, Hefei Intermediate People’s Court found that Wu Baoliang accepted a total of RMB 18.692 million, US$ 42,000, a shopping card of RMB 64,000 and a watch worth RMB 35,000, and sentenced him to life imprisonment for accepting bribes, deprived him of political rights for life, and confiscated his personal property of RMB 600,000.

        In June 2014, the Higher People’s Court of Anhui Province made a final judgment on the case of accepting bribes by Bao Baoliang, dismissed the appeal and upheld the first-instance judgment.

        According to the China Youth Daily, the briber units listed in the indictment cover almost all townships and county-level organs in Xiaoxian County. Most of the bribers are unit leaders, such as the director of the Housing and Construction Bureau, the director of the county government office, the director of the county finance bureau, and the captain of the traffic police brigade of the county public security bureau. The amount they send is more than 200,000 yuan; Members of the four leading bodies in Xiaoxian County were also accused of rushing to send money to Wu Baoliang. Zhu Yishu, deputy director of Xiaoxian People’s Congress, Wang Anmin, vice chairman of Xiaoxian CPPCC, Chen Anyuan, chairman of Xiaoxian CPPCC, Cui Hongguang, executive deputy magistrate of Xiaoxian County, and others also appeared in the indictment. They each sent tens of thousands of yuan on the grounds that "in order to get along well with Wu Baoliang, they can get support at work".

        A number of government workers in Xiaoxian said that when the old secretary fell, the new government building was only temporarily "shelved". Until July, 2013, after the document Notice of the General Office of the State Council on the Party and Government Organs Stopping Building New Buildings and Offices and Cleaning up Office Rooms (No.17 (2013) of the Central Office of the Communist Party of China) came down, Xiaoxian government even dared not move into the new building for office work, and until now the new building is still a clean room.

        Regarding the "disposal" of government buildings in the future, Yang Wenya said that this situation has been reported to the superior unit and is currently waiting for the decision of the superior unit.

The synchronous technology of pushing and assembling shield machine was successfully tested in Shanghai

This is the "Jiyue" shield machine in the workshop of Shanghai Tunnel Machinery Manufacturing Branch (photo taken on April 13, drone photo).

The synchronous technology of shield tunneling and assembling independently developed by Shanghai Tunnel Engineering Co., Ltd. has been successfully tested recently, and the first push-and-assemble synchronous shield machine is about to go offline. In the process of tunnel construction, the shield machine using this technology will realize the parallel operation of tunneling and assembly, which will greatly improve the construction efficiency.

In the traditional shield machine construction, the construction process is generally advancing, stopping and assembling. Every time the shield machine goes forward, it needs to stop in situ, complete the assembly of a segment, and then continue the excavation. Tunnel excavation and segment assembly are carried out in series. The parallel operation of excavation and assembly can be realized by applying the push-and-push synchronization technology. Relevant simulation tests show that the push-and-push synchronization technology will greatly reduce the operation time of each ring segment of shield machine and improve the construction efficiency by 30% to 50%.

The truth behind those "super foods"

  "Drinking some enzymes every day can reduce weight and improve detoxification and intestinal flora."

  "Drink more red wine. The resveratrol in it can prevent cardiovascular diseases and help you live longer."

  "Eating bird’s nest can beautify, resist aging and supplement collagen."

  "Recently, green juice is particularly popular and has become a health food in online celebrity. I heard that it can lose weight!"

  "Just after giving birth to a child, my mother bought me Ejiao to replenish blood and iron and recuperate my body."

  … …

  Do these words sound familiar? Have you eaten all these foods that are said to have magical effects?

  In recent years, "health care" has long been not only a standard for middle-aged and elderly people, but also people of all ages have their own understanding of health care. Young people are busy detoxification, beauty care and weight loss, while middle-aged and elderly people are busy chasing longevity, anti-oxidation and conditioning chronic diseases. For these "pursuits", everyone invariably locked their eyes on some "super foods" that were passed on by word of mouth or widely advertised. However, are these generally expensive "super foods" really so magical?

  On November 28th, a series of activities of "Food Safety Popularization into the Community" co-sponsored by Beijing Youth Newspaper and chinese institute of food science and technology, and co-organized by Yantai Xinhe Enterprise Food Co., Ltd. and Beijing Youth Daily Reader Club entered the Zaoying Nanli Community of Maidian in Chaoyang District, Beijing.

  In this issue, we specially invited Dr. Kai Zhong, a senior food safety science expert. In the lecture for more than an hour, Dr. Kai Zhong took stock of the most concerned "health-preserving" foods in recent years and re-interpreted the scientific common sense behind the foods from a scientific perspective.

  ferment

  Eating fruits and vegetables is more nutritious than drinking enzymes.

  "Enzyme, simply speaking, is pickle water without salt." The sharp Dr. Kai Zhong tore the magic veil of enzyme in one sentence. After everyone’s laughter ended, Dr. Kai Zhong bluntly said: "Many people know that enzymes contain polyphenols and flavonoids, but they don’t know that they are not produced by fermentation, but are already in fruits and vegetables. Therefore, eating fruits and vegetables is more nutritious than drinking enzymes. "

  In addition, the so-called digestive enzymes contained in enzymes are not special, but widespread, and the output of human intestinal flora is actually greater. At the same time, it is very unlikely that exogenous biological enzymes, such as enzymes, can play a role after entering the body. Dr. Kai Zhong explained: "These enzymes that we ingest from the outside world can participate in digestion and metabolism very little. Most of them are broken by gastric acid when they arrive in the stomach, and there is no way to participate in the later process."

  Regarding the weight-reducing effect of enzymes, Kai Zhong pointed out that enzymes themselves have no nutrition. On the one hand, it is possible to add western medicine secretly, on the other hand, it is to create a sense of ritual by eating enzymes to guide people to eat less.

  Anti-oxidation and anti-aging are also the widely circulated effects of enzymes, and Dr. Kai Zhong told everyone bluntly: "So far, no health care products can really effectively resist aging." Dr. Kai Zhong pointed out that in fact, many people did not really understand the concept of "oxidation". The human body can live by oxidation. Without oxidation reaction in the body, there is no way to turn the food it eats into energy. Excessive intake of antioxidants is not good for the body, but is against the metabolic function of the human body. More recent evidence shows that intake of antioxidants will increase all-cause mortality, that is, it will increase the possibility of causing various diseases.

  red wine

  The secret of the French’s health is actually the "Mediterranean diet" model.

  "The influence of a certain food on your health is far less than that of your dietary structure." Dr. Kai Zhong repeatedly emphasized this concept in the lecture, and he immediately gave an example. "Many people have heard that resveratrol in wine has a healthy effect, but in fact, the impact of drinking wine on your health is far less than that of three meals a day. If you don’t eat well for three meals a day, it’s not reliable to just drink wine. To put it bluntly, it’s just a waste of money and a psychological comfort. "

  In fact, there is no direct evidence to prove that resveratrol has a healthy effect, and the average resveratrol content in a bottle of red wine does not exceed 3 mg, so the so-called health effect is almost negligible. On the contrary, it should be noted that excessive intake of resveratrol will have side effects on the body. "Eating more than 2 grams a day may cause symptoms such as nausea and diarrhea."

  Then why is the incidence of cardiovascular disease really low in the French, which loves to drink red wine? Kai Zhong explained: "the French’s health actually benefits from their diet structure, which is known to all ‘ Mediterranean diet ’ Mode. The intake of sugar is low, and there are more fruits and vegetables, aquatic products and dairy products. "

  edible bird’s nests

  Nutrition is not as good as milk and eggs.

  Bird’s nest belongs to a traditional "health-preserving" food, but Dr. Kai Zhong told us that the nutritional components in bird’s nest are not as good as milk and eggs. For example, bird’s nest acid, a symbolic nutrient of bird’s nest, is also called sialic acid, and the price of pure products is about one tenth of that of bird’s nest. In fact, animal foods generally contain a small amount of sialic acid, which can be synthesized by the human body itself. The so-called efficacy evidence of sialic acid also comes from animal experiments, and the dose is far greater than the consumption of normal human beings.

  The other two substances contained in bird’s nest, epidermal growth factor and colony stimulating factor, can also be synthesized by the human body itself, and have nothing to do with the so-called "blood-enriching" and "beauty-nourishing" effects. "Epidermal growth factor does not refer to the epidermis on our face, but refers to the cell membrane, which has nothing to do with our skin. Moreover, these two substances are destroyed once they are stewed. "

  What about the blood swallow? The red color of blood swallows is actually because the stone wall where swallows nest contains iron. "Red is iron oxide, just like ‘ Rust ’ The same, but the iron absorbed by the human body should be bivalent iron, not the trivalent iron in the blood swallow, so the blood swallow can neither supplement iron nor replenish blood. "

  spirulina

  The "ideal food for the 21st century" is aimed at the poor people in Africa.

  Spirulina is one of the health products mentioned more in recent years, and all kinds of spirulina health products are very popular. Dr. Kai Zhong recognized that spirulina really has the characteristics of high protein and low fat, and can be used as the raw material of ordinary food, but its other nutritional components are not surprising, and there is not much difference between spirulina and ordinary food. The reason why it was once rated as the most ideal food in the 21st century by FAO is actually mainly aimed at people in poor areas of Africa, because its own nutritional density is relatively high and its cost is relatively low, so it is very suitable for supplementary nutrition.

  Then, is it true that spirulina is mentioned in the advertisement that it can improve 17 kinds of effects such as seasonal allergy, insulin resistance of AIDS patients, diabetes, high cholesterol, hypertension, long-term fatigue, menopause and obesity? Dr. Kai Zhong gave a definite answer — — All of them were denied by the FDA (Food and Drug Administration) after the experiment.

  Dr Kai Zhong also mentioned the food safety of spirulina. In 2003, the China Center for Disease Control and Prevention tested the spirulina products on the market and found that the pollution of microcystins was very common. At that time, the conclusion was that even if you only eat 4 grams of spirulina every day, its health risks should not be ignored, and it may contain carcinogens.

  E-gelatin

  The effect of "nourishing" is reflected in the age of nutritional deficiency

  It is clearly recorded in the Bielu of Famous Doctors compiled from the Three Kingdoms to the Southern and Northern Dynasties that Ejiao is made of boiled cowhide. "Qi Min Yao Shu" also records that buffalo hide, buffalo hide and pigskin are the best for cooking glue, followed by donkey, horse, camel and mule skin. It was not until the Five Dynasties to the Song Dynasty that the donkey skin was countered because of the "ban on cowhide".

  As a traditional folk food that has lasted for thousands of years in China, we should be more careful about its efficacy. Dr. Kai Zhong said that there are many Chinese medical classics about Ejiao, but most of them "learn from each other". There are more than 5,000 papers on Ejiao, but most of them are Chinese journals. At present, the mechanism of Ejiao’s "efficacy" is not clear and the research results are inconsistent.

  Secondly, the cooking of Ejiao does not have to be donkey skin. In fact, the ingredients made from animal skins such as pig skin and cowhide are similar. Therefore, it is impossible to explain the difference between donkey skin, pig skin and cowhide.

  Then why does Ejiao become a nourishing prescription? According to Dr. Kai Zhong, at that time, it was because Chinese people were in the age of nutritional deficiency, and Ejiao itself provided a certain protein, and its ingredients, such as sesame, red dates, longan and walnuts, also provided a lot of sugar, which was a "big supplement" for people with low material living standards.

  aloe

  Most aloe vera is inedible.

  When it comes to aloe, many people know something about the laxative effect of aloe capsules. However, Dr. Kai Zhong emphasized that aloe vera can relieve constipation because it contains emodin. Emodin can irritate the intestine, and it has potential carcinogenicity and hepatotoxicity, and may even lead to miscarriage of pregnant women, so it should be used with great caution.

  Internal use is unreasonable, so will external use have an effect? Dr. Kai Zhong replied that there is actually insufficient evidence about the efficacy of aloe vera in "treating burns, trauma, sun protection and moisturizing". The efficacy of "anti-oxidation, anti-aging, treating ulcers, stimulating cell regeneration, repairing damaged skin, etc." is simply not established.

  Dr. Kai Zhong did not forget to remind everyone that cases of aloe allergy are not uncommon, and in fact, most aloe vera is inedible. Therefore, it is suggested that everyone should not use aloe vera without authorization.

  Barley green juice

  Getting cellulose is not as good as eating fresh vegetables directly.

  "Barley green juice is ‘ Raw food doctrine ’ The product of, it satisfies people ‘ Return to the original ’ Psychological demands ",referring to barley green juice which has been very popular in recent years, Dr. Kai Zhong said.

  Through various nutritional studies, it is found that the nutrients in barley green juice are very common, such as cellulose that promotes defecation, and we can also get it by eating fresh vegetables. As for other functions of green juice, there is no reliable evidence.

  Moreover, barley green juice was actually first used by Americans as animal feed. Later, some people marketed this dry powder made of wheat seedlings and malt into food for people. After many years, it spread to Japan and later to China. It is not what many people think, but the "secret recipe" of Japan.

  Royal jelly and propolis

  In fact, it is "the saliva of bees" and "the caulking agent of beehives"

  What is royal jelly? Dr. Kai Zhong gave the clearest explanation: Royal jelly is the oral secretion of worker bees (infertile female bees), which is used to feed the larvae and queens of bees. It is also called "bee saliva" abroad.

  Kai Zhong said that royal jelly may have hormone-like effects, so children should not eat it. In addition, it may cause allergies. "Royal jelly is not without nutritional value, but 12%-15% of protein, 10%-16% of sugar, 3%-7% of lipids, a small amount of amino acids, minerals, vitamins, phytosterols, choline, etc., and royal jelly acid are actually not much different from our ordinary food. In fact, the various health functions of royal jelly were not approved by the European Union when it was evaluated in 2011. American royal jelly has been repeatedly warned because of its efficacy propaganda. "

  What is propolis? Kai Zhong used vivid words to describe it: "A kind of ‘ Building materials ’ , the jointing agent of the honeycomb. " He further explained that "the most important thing in propolis is inedible resin. Typical propolis contains about 55% resin, 30% beeswax, 10% volatile oil and 5% pollen. The propolis we eat is scraped off the putty and re-extracted with organic solvents, mainly flavonoids and polyphenols. "

  So what about the nutritional components of flavonoids and polyphenols? "It’s better to eat fruits and vegetables," Kai Zhong said. Polyphenols come from plant secretions, so it’s easy to fake them. Moreover, propolis may only be effective in relieving some herpes symptoms and oral inflammation, but its effectiveness in treating burns, trauma, ulcers, improving immunity and anti-cancer can not be judged because of too few clinical data.

  The Secret Behind, the "super food", Dr. Kai Zhong finally concluded that the three secrets of health are genes, self-discipline and law. Apart from everyone’s different genetic characteristics, what we can do is to maintain the self-discipline of living habits, conform to the laws of human body operation, and pay attention to balanced diet and nutrition. Instead of spending a lot of money and listening to unreliable advertisements, we should shift our attention to health care to our daily diet. In other words: "Eating well is more important than anything else!"
