Follow the General Secretary to See China | Nanjing Strong Chain of Smart Grid, Towards a World-class Industrial Cluster

  Who is stronger in smart grid?

  In 2021, Jiangsu Nanjing smart grid industry won the advanced manufacturing cluster competition of the Ministry of Industry and Information Technology and became the "national team" of the advanced manufacturing cluster; In 2022, Nanjing launched an action plan to build a 500 billion-level smart grid industrial cluster; In June this year, the Nanjing Action Plan for Promoting a Strong Industrial City (2023— 2025) proposes that by 2025, Nanjing smart grid will become a leading world-class industrial cluster in China. From leading the country to competing for the world, Nanjing has industrial ambitions.

  Nanrui Group is undoubtedly the flagship of this industrial aircraft carrier. In 2022, the industrial scale of smart grid cluster in Nanjing reached 268 billion yuan, of which Nanrui Group realized operating income of 47.8 billion yuan, up 16.3% year-on-year.

  On the afternoon of July 6th, General Secretary of Supreme Leader visited Nanrui Group Co., Ltd. in Nanjing. Xinhua News Agency reporter Xie Huanchi photo

  On the afternoon of July 6th, General Secretary of the Supreme Leader came to Nanrui Group in Jiangning Development Zone, Nanjing for investigation and study, listened to the general introduction of Nanjing’s national advanced manufacturing cluster of smart grid, and looked at the display of independent and controllable technology products of enterprises.

  A few days ago, People’s Daily reporter walked into Nanrui Group, and the book on the wall of the exhibition hall read the important instructions of the General Secretary during his inspection: "Energy security and safety are related to the national economy and people’s livelihood and cannot be ignored for a moment ‘ The big country ’ " "It is necessary to accelerate the iterative upgrading of key technologies and core products and the empowerment of new technology wisdom to improve national energy security and support capabilities".

  Heart is "the country’s greatest"

  Nanrui Exhibition Hall is the first stop for General Secretary of Supreme Leader to visit Nanrui Group. Here we can see the development course of Nanrui Group: it developed from Nanjing Institute of Automation, Ministry of Electric Power, which was established in 1973. Through the continuous efforts of several generations of scientific and technological personnel, it has won 86 national-level scientific and technological awards, and achieved international leadership and independent control in important sectors such as UHV, large power grid security and stability, power grid dispatching automation and relay protection.

  From lighting the light bulb to lighting the industry, the new power system has developed into a huge and complex industrial system, and its safe and stable operation is a "national power" and a world-class problem. In the exhibition hall of Nanrui, the 10 characters of "Guardian of Safe Operation of Power Grid" are particularly eye-catching. Such confidence comes from the power grid safety and stability device and control system developed by Xue Yusheng team of Nanrui Group.

  Xue Yusheng, who is 82 years old, is an academician of China Academy of Engineering trained by Nanrui Group. He has been engaged in the research of power system stability theory and power system automation since he studied PhD in 1985. In his view, the "newness" of the new power system lies in the need to adaptively respond to the uncertain state and events in various related fields, and also in meeting the multi-objective optimization needs in different fields, etc. "This requires us to carry out a large number of innovative work at the source and solve problems one by one."

  However, the process of tackling key problems in scientific research is arduous, not only to sit on the "cold bench", but also to bear the doubts of the industry sometimes. Xue Feng, chief expert of State Grid and director of the system protection laboratory of Nanrui Group, joined the Xue Yusheng team in 1992. He still remembers that Xue Yusheng used "self-knowledge, loneliness" as his motto to encourage the team. Based on the actual needs of the safe and stable operation of the power grid, they simulated various states of the power grid operation, constantly tried various parameters for theoretical derivation, and repeatedly verified the new method.

  It takes ten years to sharpen a sword, and hard work pays off. Today, the WARMAP system developed by Xue Yusheng team has covered more than 90% of the provincial power grids in China, and established a comprehensive advantage in the field of power outage early warning system for large power grids.

  In recent years, Nanrui Group has also achieved a gorgeous turn from "following" to "leading" in the UHV field. It is understood that Nanrui Group has broken foreign blockades and achieved international leadership in technologies such as UHV, flexible HVDC transmission, large power grid security and stability, power grid dispatching and relay protection, and its products and services have been delivered to more than 110 countries and regions around the world.

  "Run one stick after another"

  The sun is burning outside the window and the indoor atmosphere is warm. Jin Yulong is discussing some key technical difficulties in the research and development of virtual power plant system with his colleagues. Since he joined the Power Grid Application Research and Development Center of Nanrui Research Institute for four years, he has devoted almost all his body and mind to this project.

  "Virtual power plant is a system that manages and dispatches distributed energy through information technology and intelligent equipment. Although it is characterized by virtuality, its role is really worthwhile." Jin Yulong takes a large-scale commercial complex as an example. During the peak hours of power consumption in summer, the virtual power plant controller can realize minute-level or second-level remote control, and the temperature of the central air conditioner can be raised by 2~3 degrees Celsius, which can effectively reduce the peak load and ensure the safe supply of power.

  "If we can aggregate more buildings and factories, we can better release the potential of existing electricity and ensure the safety of the power grid without building new power plants." Jin Yulong said that at present, the team has basically formed a set of relatively mature virtual power plant solutions, and related achievements have been demonstrated and applied in Jiangsu, Shanxi, Ningxia and other places.

  Dedicated to the tide of the times of self-reliance and self-improvement in science and technology, Jin Yulong really felt the message from the Supreme Leader General Secretary "Take ‘ Do one thing in a lifetime ’ Persistence, tackling high-tech problems and achieving a valuable life ". On the afternoon of July 6, in the intelligent manufacturing production area of Nanrui Group, the general secretary asked: "Are you satisfied with working here?" In the unanimous answer, "Satisfied!" in Jinyu Longkou. From the heart. It is understood that as a leader in the young scientific research group, he got the equity incentive last year.

  "Scientific research is an endless long-distance running, which requires both ‘ Do one thing in a lifetime ’ Persistence, but also through the talent incentive policy to let the scientific research team ‘ Run one stick after another ’ 。” Zhang Yan, deputy director of the human resources department of Nanrui Group, said that they are speeding up the establishment of a capability evaluation system and a performance appraisal system oriented to innovative value, ability and contribution, and taking the lead in creating a multi-medium and long-term incentive "experimental field", thus forming a situation in which young talents are competing with each other.

  Nowadays, young talents have become a pillar here, and group-level experts under 40 account for more than 65%. Zhang Yan introduced that among the winners of Nanrui Group’s science and technology awards in 2020, the proportion under 40 years old exceeded 60%; Among the "333 High-level Talents Training Objects" selected in Jiangsu Province in 2021, youth accounted for more than 20%; In the past two years, there were 9 candidates selected for the Young Talents Promotion Project of State Grid Corporation and the Young Talents Promotion Project of China Electrical Engineering Society, with young people under 35 accounting for more than 40%.

  I personally listened to the words of the Supreme Leader General Secretary encouraging young R&D personnel, and Huang Guiyuan was deeply touched after 00. He graduated from Nanjing University with a major in software engineering last year, and is currently engaged in the interface visualization of power dispatching system. "R&D is not a rush, I want to be like the general secretary, ‘ Aim high, be down-to-earth, and move forward step by step ’ . I believe that our young people will be able to provoke the beam of rejuvenating the country through science and technology! " He said.

  Industrial ambition of gathering potential and strengthening chain

  During this inspection tour in Jiangsu, the General Secretary of the Supreme Leader entrusted Jiangsu with "four new" major tasks, one of which was "showing new achievements in strengthening the chain and extending the chain".

  In the past half century, Nanrui Group has developed from a unit with less than 100 employees to a modern enterprise with 14,000 employees. Correspondingly, the smart grid industry in Nanjing has grown from scratch to cluster, with more than 1,200 related enterprises in the city, accounting for 80% of the national market, forming a "one valley and two districts" cluster development pattern with Jiangning Smart Grid Industry Valley as the core and Nanjing Economic and Technological Development Zone and Nanjing Jiangbei New District as the two wings.

  The national smart grid sees Nanjing, and the Nanjing smart grid sees Jiangning. As early as the "Twelfth Five-Year Plan" period, Jiangning District planned to build a smart grid industrial park of 7 square kilometers. In recent years, it has built 13 state-level technology business incubators and 20 state-level creative spaces, providing an important platform for accelerating the industrialization of new technologies, improving the regional innovation ecology and gathering innovative small and medium-sized enterprises. At present, around Nanrui Group, Jiangning Smart Grid Industry Valley has gathered more than 280 affiliated enterprises, covering nine key links in the industrial chain.

  "Our main product is power equipment, which is a very critical part of the industrial chain." Huanyu Group (Nanjing) Co., Ltd. settled in Jiangning Binjiang Economic Development Zone in 2009. Fan Jianlun, vice president of the company, said that the company has cooperated with Nanrui Group, Guodian Nanzi, Jinzhi Technology and other companies in Jiangning. "Undoubtedly, a sound local industrial chain has greatly helped our business development."

  Jiangsu Hengan Energy Storage Technology Co., Ltd. just settled in Jiangning Development Zone last year. Here, enterprises have found a way from scientific research and development to industrial application. "The process of a project from research and development to mass production is not easy." In the view of Duan Huiyuan, the general manager of the company, the team has been engaged in the research of zinc-bromine flow battery for 17 years and entered the industrialization stage. "If we rely solely on our own strength, it will take a lot of time and capital costs."

  Duan Huiyuan introduced that when building a new automated production line, they found local equipment provided by Copilon, and Eston provided robots for assembly of production components for the production line. They also sought the research team of Southeast University to jointly solve the problem of improving battery conversion efficiency, and also discussed technical cooperation with Nanrui Group. When they learned that a cooperative enterprise was developing photovoltaic power generation business, they changed from "customers" to "suppliers" to design energy storage power stations for them.

  "Our first production line took a year and a half from design to commissioning. The new production line here is expected to complete equipment production, installation and commissioning in half a year, and it will be put into production around the Spring Festival next year. " Duan Huiyuan said frankly that the local mature industrial chain "ecological circle" has greatly accelerated the pace of enterprise development.

  "We have implemented regional dislocation development and continuously optimized the industrial layout. The planned output value of smart grid industry has increased from 67.6 billion yuan in 2018 to 122.7 billion yuan in 2022, with a cumulative increase of 69.8%." The relevant person in charge of Jiangning District Bureau of Industry and Information Technology introduced that Jiangning Development Zone promotes the construction of smart grid industry valley around high quality, and builds the core area of smart grid high-end equipment industry and the source of original technology; Binjiang development zone takes advantage of port logistics and modern equipment manufacturing industry, focusing on introducing equipment manufacturing projects related to the shortcomings of the industrial chain; Other parks and street industrial concentration areas, combined with regional reality, guide the transformation and entrepreneurship of scientific and technological achievements related to smart grid industry.

  More than a month ago, the smart grid industry multiplication action plan of Jiangning Development Zone was released, the second phase project of Nanrui Jibao Intelligent Electrical Equipment Industrial Park started, and the project of Sunshine Power Nanjing R&D Center was signed and settled; More than two months ago, Nangang’s user-side energy storage power station, known as the "super-large charging treasure", was launched in Jiangbei New District. The industrial layout is steady, major projects are stepped up, and a 500 billion-level smart grid industrial cluster is built. Nanjing is full of horsepower and is determined to win.

Domestic prices keep running smoothly-a perspective of CPI and PPI data in the first quarter

Xinhua News Agency, Beijing, April 11th Title: Domestic prices keep running smoothly-a perspective of CPI and PPI data in the first quarter

Xinhua News Agency reporter Wei Yukun and Shui Jinchen

Since the beginning of this year, China’s prices have maintained a stable operation. The National Bureau of Statistics released data on the 11th. In the first quarter, the national consumer price index (CPI) rose by 1.3% on average compared with the same period of last year, and the national industrial producer ex-factory price index (PPI) dropped by 1.6% compared with the same period of last year, which continued to be an important "stabilizer" for global prices.

CPI runs in a reasonable range

Stabilizing prices is an important task to do a good job in this year’s economic work. This year’s government work report will set the annual increase in consumer prices at around 3%.

The latest data shows that in the first quarter, CPI continued to operate in a reasonable range, and the monthly increase was lower than the expected target of around 3%.

Dong Lijuan, chief statistician of the Urban Department of the National Bureau of Statistics, said that in January, due to factors such as the Spring Festival effect and the optimization and adjustment of epidemic prevention and control policies, CPI rose by 2.1% year-on-year, an increase of 0.3 percentage points over the previous month; In February, affected by factors such as falling consumer demand after the holiday and sufficient market supply, the year-on-year increase of CPI dropped by 1.1 percentage points compared with the previous month; In March, production and life continued to recover, and the consumer market was fully supplied. CPI rose by 0.7% year-on-year, and the growth rate dropped by 0.3 percentage points from last month.

In China’s CPI "basket" goods, food accounts for a relatively high proportion. Since the beginning of this year, the increase in food prices has continued to fall, from 6.2% in January to 2.4% in March.

From the ring comparison, the price of food changed from 2.8% in January to 1.4% in March. Dong Lijuan analyzed that in March, due to the abundant stock and the decline in consumer demand, pork prices decreased by 4.2% month-on-month; The price of fresh vegetables decreased by 7.2% month-on-month, which was 2.8 percentage points higher than that of last month.

"Vegetable production is greatly affected by meteorological conditions. Adequate sunshine and rising temperature in March are conducive to improving the growth rate of vegetables, resulting in an increase in the output of some vegetables and a downward price. In addition, due to the’ cold spring’ weather in the producing areas, the listing period of vegetables has been postponed, and the prices of lettuce, cauliflower and other varieties have fluctuated frequently. " Zhang Jing, chief analyst of the vegetable market analysis and early warning team of the Ministry of Agriculture and Rural Affairs, said.

The increase in non-food prices has declined. In March, non-food prices rose by 0.3% year-on-year, and the growth rate dropped by 0.3 percentage points from the previous month. In non-food, service prices rose by 0.8% year-on-year, with an increase of 0.2 percentage points over the previous month; The price of industrial consumer goods changed from 0.5% last month to 0.8%.

"Since the beginning of this year, the year-on-year increase of China’s core CPI has been fluctuating in the range of around 1%, which shows that the consumer prices of industrial consumer goods and services in China have remained stable." Wang Likun, an associate researcher at the Institute of Market Economy of the State Council Development Research Center, said.

PPI growth continued to fall.

Affected by factors such as the high comparative base in the same period of last year, the overall price of industrial products in China continued to decline. In the first quarter, PPI decreased by 1.6% year-on-year, including a decrease of 2.5% in March, which was 1.1 percentage points higher than that in the previous month.

From the ring comparison, in January, due to the fluctuation of international crude oil prices and the downward trend of domestic coal prices, the PPI decreased by 0.4% from the previous month. In February, the production recovery of industrial enterprises accelerated, the market demand improved, and the PPI turned flat. In March, due to the accelerated recovery of the domestic economy and the price trend of some commodities in the international market, the PPI remained flat.

Dong Lijuan analyzed that in March, domestic production and market demand continued to improve, key projects were accelerated, and the prices of steel, cement and other industries increased from the previous month. Among them, the prices of ferrous metal smelting and rolling processing industries and cement manufacturing all increased by 1.3% from the previous month. International input factors have driven down the prices of domestic oil and non-ferrous metals-related industries, among which the prices of oil and natural gas mining industry decreased by 0.9% month-on-month, and the prices of oil, coal and other fuel processing industries decreased by 0.4%. Affected by seasonal factors such as rising temperature, the demand for coal has decreased, and the price of coal mining and washing industry has dropped by 1.2%.

"The continuous decline in PPI growth will help improve the profit structure of upstream and downstream industries, ease the cost pressure of manufacturing enterprises in the middle and lower reaches, and stimulate the vitality of micro-subjects." Wang Likun said.

There is a solid foundation for keeping prices running smoothly.

Prices are related to economic operation and affect people’s lives. Experts said that with the gradual improvement of domestic demand, the supporting role for related prices will be enhanced, and the influence of international input factors still exists, and there is some pressure to stabilize prices. However, judging from the trend of the whole year, it still has a solid foundation to maintain the stable operation of prices.

Fu Linghui, a spokesperson for the National Bureau of Statistics, said that China’s grain production has maintained growth, and the grain output has been stable at more than 1.3 trillion Jin for eight consecutive years, and the inventory is relatively abundant; Pork production capacity is at a reasonable level and does not have the conditions for a sharp increase; Energy prices are stable. Last year, China effectively released advanced coal production capacity, and the energy self-sufficiency rate was above 80%. In recent years, the production of oil and natural gas has increased significantly, which is conducive to stabilizing energy prices.

The National Development and Reform Commission has made it clear that we should make overall plans to increase employment and income, and strengthen the supply and price stability of key commodities; The National Energy Administration requires that we do our best to ensure the supply and price stability of natural gas this year to ensure the demand for gas for people’s livelihood; Zunyi, Guizhou, established a unified "white list" system to guarantee supply, strengthened the mechanism of joint guarantee and supply, and ensured a strong and orderly supply of "rice bags" … Recently, all relevant departments and localities have made overall plans to ensure supply and stabilize prices.

Key enterprises have increased efforts to ensure supply and price stability, and have sufficient stocks. For example, Beijing Xinfadi Market will expand the "through train" to cover cities and build a green channel for featured agricultural products to enter Beijing; Meituan buys vegetables on the early-adopter channel of spring vegetables. Toona sinensis, shepherd’s purse, spring bamboo shoots and other fresh spring vegetables are well supplied. Cheap food markets and super discount channels are updated every day, and the prices remain generally stable.

"Looking forward to the whole year, China’s industrial and agricultural products and services are well supplied, production and marketing are smoothly connected, the market order is good, and the overall economic recovery trend will gradually appear in prices. It is expected that the overall price level will generally operate in a reasonable range." Guo Liyan, director of the Comprehensive Situation Research Office of China Macroeconomic Research Institute, said.

One minute in advance! Earthquake early warning "big horn" resounded through Chengdu night sky

  Science and Technology Daily reporter Sheng Li

  According to the China Seismological Network Center, an earthquake of magnitude 6.0 occurred near Changning County, Yibin City, Sichuan Province at 22: 55 on June 17th. After the earthquake and before the arrival of destructive seismic waves, TV screens and community broadcasts in many places in Sichuan realized the "countdown" of earthquake warning, especially in 60 communities in Chengdu High-tech Zone. 61 seconds before the earthquake struck, the short video that the warning "big horn" sounded at the same time was once "screened". What technology is used in earthquake early warning and what are its early warning channels? How do the general public receive earthquake warning? On the 18th, the reporter visited Chengdu Institute of High-tech Disaster Reduction (hereinafter referred to as the Institute for Disaster Reduction), the research and development unit of this earthquake early warning technology.

  Zhang Xiao, who lives at No.123, Guixi East Road, Chengdu High-tech Zone, was a witness to the "big horn" earthquake warning in Chengdu High-tech Zone. She was preparing to rest on the night of the earthquake on the 17th, when she suddenly heard the "countdown" of the community broadcast. "The sound is particularly loud and the whole community is ringing." Zhang Xiao said that with the end of the countdown alarm, she felt obvious shaking at home. "It is certain that the police were reported first, and it only shook later."

  After the earthquake, many places in Sichuan received earthquake early warning information through television, mobile phones and community broadcasts, which was released by the "Continental Earthquake Early Warning Network" jointly established by the Institute of Disaster Reduction and the emergency management department. According to the preliminary statistics of the Institute of Disaster Reduction, the mainland earthquake early warning network has issued early warnings to more than 200 schools in Yibin City and Leshan City, Sichuan Province, and 101 communities in Chengdu have also received early warnings. As for the early warning "big horn" that resounded through 60 communities in Chengdu High-tech Zone, it was jointly launched by Chengdu High-tech Zone and Disaster Reduction Institute on May 9 last year.

  How does "Big Horn" realize earthquake early warning? Wang Gang, director of the Sichuan Provincial Key Laboratory of Earthquake Early Warning and director of the Institute of Disaster Reduction, said that earthquake early warning is a technology that provides users with early warning for several seconds to dozens of seconds by using the principle that electric waves are faster than seismic waves after an earthquake.

  As for the early warning process of the Changning earthquake, Wang Gang said that in the more than 10 years after the Wenchuan earthquake, the mainland earthquake early warning network jointly built by the Disaster Reduction Institute and the earthquake department of the emergency management department (the original city and county earthquake prevention and disaster reduction department) has covered 2.2 million square kilometers of land in China.

  "In the huge area covered by this network (continental earthquake early warning network), once an earthquake occurs, earthquake early warning stations all over it can collect earthquake information and respond quickly." He said that after the earthquake, after the seismic wave propagates from underground to the special ground monitoring station of the mainland earthquake early warning network, the seismic wave summary information will be extracted by the first nearby station, and then it will be extracted by another nearby station again to complete the on-site earthquake judgment. The double-extracted seismic information will be transmitted to the early warning center located in the disaster reduction institute, and then comprehensively analyzed by the center to issue early warnings to all terminals.

  After the Changning M6.0 earthquake and before the arrival of seismic waves, the warning time of Yibin City, 51km away from the epicenter, was 10 seconds, and the estimated intensity was 5.2 degrees. The early warning time for Luzhou City, which is 80 kilometers away from the epicenter, is 18 seconds, and the estimated intensity is 4.6 degrees; The early warning time for Zigong City, which is 111 kilometers away from the epicenter, is 27 seconds, and the estimated intensity is 4.1 degrees. "It can be clearly seen that the farther away from the epicenter, the longer the warning time." He said that the terminals that reached the intensity threshold in this early warning all issued earthquake early warning alarms or tips, and the terminals that did not reach the intensity threshold did not issue earthquake early warning as required.

  "That is to say, after the Changning earthquake, if the intensity level of seismic waves arriving at different warning locations is lower than the preset value, the alarm will not sound, which is why some people in various places have received early warnings and some have not." Wang Wei said.

  At present, the earthquake early warning methods that can be realized by the mainland earthquake early warning network include installing "early warning receiving terminal system" in schools, communities and high-risk enterprises, network early warning on mobile platforms such as mobile phones, and TV pop-up early warning. Among them, the early warning terminal system can connect loudspeakers and industrial control systems for earthquake risk control. For example, he said that the earthquake early warning emergency disposal system installed in Zone D of Tianfu Software Park in Chengdu High-tech Zone can control the elevator to realize automatic flat-floor shutdown, while high-risk chemical enterprises can realize automatic shutdown of production systems.

  On the mobile side, early warning information can be published on platforms such as Weibo, WeChat and APP software. Ordinary users can download the "Earthquake Early Warning APP" developed by the Disaster Reduction Institute to realize mobile phone early warning. Finally, in terms of TV early warning, on May 27th this year, Sichuan Radio and Television Network took the lead in connecting the provincial radio and television network with the earthquake early warning network. At present, TV earthquake early warning in Sichuan has extended to 13 cities and states, covering 79 districts and counties. When an earthquake occurs, the TV will give an early warning by means of "hanging small corner pop-up window" or "large center pop-up window" in the lower right corner.

Minister of Agriculture: Deepening Rural Reform and Promoting Agricultural Modernization

Deepening Rural Reform and Promoting Agricultural Modernization —— Interview with Minister of Agriculture Han Changfu

Xinhua News Agency, Beijing, May 31st (Reporter Lin Hui)General Secretary of the Supreme Leader recently hosted a rural reform forum in Xiaogang Village, Fengyang County, Anhui Province and delivered an important speech. Han Changfu, Minister of Agriculture, said in an interview with reporters that the important speech of the General Secretary in Xiaogang Village is a strong signal to strengthen agriculture and attach importance to agriculture, and it is also a heavy hammer to speed up rural reform and development, and it is also a horn to promote agricultural modernization, which further strengthens our confidence and determination to promote rural reform, development and stability.

Deepen the reform of rural land system and collective property rights system.

Q:What key points should be grasped in rural reform at present and in the future?

Han Changfu:Reform is the driving force of agricultural and rural development. In accordance with the spirit of the General Secretary’s important speech and the requirements of the central government’s deployment, we should base ourselves on the present and focus on the long-term, and do a good job in deepening the reform of rural land system and rural collective property rights system, which are the key tasks of laying the foundation and managing the long-term.

The main line of deepening rural reform under the new situation is still to deal with the relationship between farmers and land. With the deepening of industrialization and urbanization, the subject of land contracting right and the subject of management right are separated in fact, which puts forward new requirements for the design of land system. Realizing the separation of contracting right and management right is the direction and major innovation of deepening the reform of rural land system, which is conducive to safeguarding and realizing farmers’ rights and interests and stimulating the vitality of rural development. The premise of "separation of powers" is "implementation of ownership". We are studying the problem of stabilizing rural land in contract relationship and keeping it unchanged for a long time, and put forward specific opinions on the contract period and the way of extending the contract after the expiration of the second round. The basis of "separation of powers" is "stable contracting right". By carrying out registration and certification of contracted land, farmers can really eat "reassurance". The core of "separation of powers" is "freeing management rights", and it is necessary to encourage exploration and innovation, respect farmers’ choices, and develop various forms of agricultural moderate scale operations such as land circulation, land trust and land shareholding.

The reform of rural collective property rights system is a major institutional innovation after the rural household contract responsibility system, which takes care of the long-term, fundamental and overall situation. Promoting this reform is conducive to the formation of an innovative and developed rural property rights system, the improvement of the rural basic management system, the promotion of farmers’ property rights and interests, and the sharing of the fruits of reform and development among the broad masses of farmers. According to the requirements of the central authorities, it is imperative to find out the family background and establish the institutional framework. We should pay close attention to the introduction of reform documents and do a good job in pilot projects, actively explore the quantification of shares to collective members and implement the reform of joint-stock cooperative system, promote the construction of a rural collective property right system with clear ownership, complete power, smooth circulation and strict protection, realize the equal exchange of urban and rural factors, and increase farmers’ property income.

Constructing "Three Systems" and Accelerating Agricultural Modernization

Q:What ideas and measures does the Ministry of Agriculture have in promoting agricultural modernization?

Han Changfu:It is necessary to accelerate agricultural modernization by building a modern agricultural industrial system, production system and management system.

First, we must promote the structural reform of the agricultural supply side and build a modern agricultural industrial system. Guided by market demand, optimize, raise and refine agricultural industry. Since last year, the Ministry of Agriculture has deployed the structural adjustment of planting, animal husbandry and fishery. In the next step, we will intensify our work, pay close attention to the implementation of measures, and make a good combination of agricultural structural adjustment.

The second is to strengthen the support of material technology and equipment and build a modern agricultural production system. Arm agriculture with modern facilities, equipment and technical means, develop green production, and improve the level of improved varieties, mechanization, science and technology, informationization and standardization of agriculture.

The third is to develop moderate scale management and build a modern agricultural management system. Promote the common development of family management, collective management, cooperative management and enterprise management, and improve the level of intensification, scale, organization, socialization and industrialization of agricultural management. The key point is to cultivate new agricultural business entities and new professional farmers, develop agricultural producer services, pay close attention to study and improve the support policies for new business entities, explore various forms of moderate scale operations, and solve the problems of "who will plant the land" and low operating efficiency.

Unswervingly adhere to and improve the basic management system in rural areas

Q:What should we focus on in promoting rural reform and development?

Han Changfu:To maintain rural harmony and stability, the first thing is to stabilize the rural basic management system. Rural basic management system is not only the foundation of rural economic system, but also the basis of rural social governance mechanism, which affects the whole body. To deepen rural reform, the biggest policy is to adhere to and improve the basic rural management system and never waver. To insist on the collective ownership of rural land by farmers, the basic position of family management and the stabilization of land contract relationship, these three "hard levers" must be grasped well. In particular, the reform of rural land system must be carried out prudently and steadily. If you can’t see clearly for a while, don’t rush to move, have some historical patience and don’t rush into it. Land is the survival foundation and emotional dependence of farmers, and it is the "lifeblood" of farmers. Only when the rural land contract relationship is stable can people’s hearts be stable. In the reform of rural land system, we must respect the wishes of farmers, do not engage in coercive orders, and ensure that farmers’ rights and interests are not harmed.

To maintain rural harmony and stability, we must stabilize effective rural policies. The policy is stable, the people are stable, and the countryside is stable. It is necessary to continuously increase and improve the support policies, so that farmers can get more benefits and have more "sense of gain". China’s agricultural and rural economic development in the Twelfth Five-Year Plan has created another best period in history, which proves that a series of policies of the central government to strengthen agriculture, benefit farmers and enrich farmers in recent years are effective and must be adhered to for a long time and constantly improved.

To maintain rural harmony and stability, we must also vigorously promote farmers’ employment and income. Increasing farmers’ employment and income is the biggest livelihood in rural areas. Only when farmers have jobs and "money bags" really swell up can rural harmony and stability be based. It is necessary to support farmers’ employment and entrepreneurship, especially the entrepreneurship of returning migrant workers, as the focus of promoting farmers’ income. Broaden the channels for farmers to increase their income, tap the potential of increasing income within agriculture, vigorously develop new industries and formats such as leisure agriculture and e-commerce, cultivate new income growth points, and promote farmers to increase their income continuously and rapidly.

26.2 billion! China’s film transcripts were released in the first half of the year, and 5 films broke 1 billion.


Special feature of 1905 film network With the blessing of excellent films at home and abroad, the mainland film market in China delivered a satisfactory answer sheet in the first half of 2023.


According to the statistics of Cat’s Eye Professional Edition, as of 21: 00 on June 30th, the box office of China mainland film market in the first half of the year has reached 26.23 billion yuan, up more than 50% compared with 17.18 billion yuan last year. This also shows that after three years of epidemic, with the joint support of the audience and filmmakers, the China film market is still full of vitality.


The splendid Spring Festival file made the mainland film market welcome a good start in 2023. On the last day of the first month in 2023, the total box office of cinema films in China exceeded 10 billion, setting a record of breaking 10 billion at the fastest annual box office in China film history, and also becoming the best box office achievement in China film history in January.


The Dragon Boat Festival, which created the second best performance in the history of the same period, is the icing on the cake for the first half of the mainland film market in 2023. As of June 30th, thanks to the new Dragon Boat Festival film, the box office on weekdays has exceeded 200 million for five consecutive days.



Policy support+explosions frequently achieved 26.2 billion box office.

Domestic movies still play the role of the main box office.


In the first half of 2023, the overall box office exceeded 26.1 billion yuan, exceeding industry expectations. This has also greatly boosted the morale of filmmakers and increased the market’s confidence in the future development of China’s film industry.


He Yu, a data analyst at Cat’s Eye Research Institute, believes that there are two main reasons why the market can achieve such results: First, thanks to the strong support of the national policy for the film industry after the market is liberalized.


On the film supply side, six films in the Spring Festival in 2023 cover 11 themes to meet the needs of audiences of all ages. From February to June after the Spring Festival, a large number of domestic and imported new films continued to be supplied steadily, effectively pulling movie users back to the cinema.



According to the statistics of big data of Cat’s Eye Platform, the number of people watching movies and the frequency of watching movies during the big period in 2023 (from Spring Festival to May 1st, from May 1st to Dragon Boat Festival) have obviously increased compared with the same period in 2021. In addition to the supply, the pre-screening announcement period has also been greatly extended, which provides more time for the film to spread information to the public, which is conducive to maximizing the popularity of the film before screening and achieving higher box office.


In addition, on May 23rd, the policy of the Ministry of Finance and the State Film Bureau to exempt the special funds for the development of the national film industry in stages is also of great benefit to the development of the film industry in China at this stage. The exemption period from May 1, 2023 to October 31, 2023, covering the two prime periods of summer and National Day, will stimulate more new films to enter the market during this period and further promote the prosperity and development of the domestic film market.



Secondly, in the first half of this year, the overall quality of the film was high, with frequent explosions.


According to the cat’s eye score, in the first half of 2023, there were as many as 40 films with the audience’s ticket purchase score ≥9, exceeding 37 films in 2022. A number of excellent films have been released one after another, accelerating the recovery of the film market.


The Spring Festival file and the "dual-core drive" helped the Spring Festival file in 2023 to achieve the second best performance in the history of the total box office. In 2023, the "520" file set a record for the single-day box office of "520" in China film history with 332 million yuan.



In addition, the May 1st stall, the Dark Horse "Disappeared She" in the Dragon Boat Festival stall, etc., are also applauded and popular. Japanese animation "Journey to the Bell Bud" ranks first and second in the box office of Japanese movies in the history of China Mainland with its IP and high-quality content.



In the first half of 2023, China mainland film market, domestic films still played the role of the main box office.


According to statistics, in the first half of 2023, there were 30 movies with box office exceeding 100 million. Among them, there are 18 domestic films and 12 imported films. Among these 30 works, compared with domestic films, the imported films are mainly superhero films and animated films.


It is worth mentioning that in the first half of 2023, five films that broke the box office of 1 billion were all domestic films, with a total box office of 12.821 billion yuan. Among them, the cumulative box office of the new films "Man Jiang Hong" and "Wandering Earth 2" in the Spring Festival in 2023 exceeded 4 billion yuan.

In the first half of 2023, five films broke 1 billion.


Comedy and suspense works are more likely to explode.

The mainstream audience is getting older.


In the first half of 2023, domestic films containing comedy and suspense elements are more likely to explode.


This year’s Spring Festival, the script "Man Jiang Hong" with strong style, skillfully integrated comedy and suspense elements, and dedicated a Rashomon drama to the audience. In the end, the cumulative box office of the film reached 4.544 billion yuan, which not only created a new high in the box office of the director’s career, but also temporarily ranked as the single box office champion in the mainland film market in 2023.



The pure comedy Unfamiliar in Life released on May 1st has benefited from the double advantages of genre advantages and relaxed competitive environment, and the cumulative box office has reached 1.183 billion yuan. The box office success of the film fully shows that comedy is still just needed by the market. This film is also the second film with a box office of over one billion after 2018 in the May 1st file of China Film History.


At present, The Disappeared She, which is being shown, is full of suspense elements, and the cumulative box office has exceeded 1.8 billion yuan. The film is based on real events, which is highly topical in society and has broken circles.



In addition, the age range of the main audience in the market is quietly changing, showing an upward trend.


At the opening forum of the 25th Shanghai International Film Festival held in Jin Jue in early June, Fu Ruoqing, chairman of China Film Group, said frankly that "from the start of film industrialization in China to now, the mainstream audience has grown up by about 20 years, and with the entry of new audiences, they have a greater demand for empathy and resonance in movies, so localized stories are more popular." The group resonance caused by domestic films such as "She Disappeared" makes the works more realistic.


"Midnight box office sells very well! Why is it a midnight show? That is, when the old people and children are asleep, the couple will go out to see a movie. " For the growth of the mainstream audience’s age, the chairman of Bona Film is also deeply touched. Yu Dong believes that the main consumers of movies are mostly middle-aged, and they value the level of film storytelling more.



In the first half of 2023, the film market in China has closed beyond expectations. With the blessing of new films in July, the mainland film market started optimistically in the second half, and the summer file in 2023 is also expected to return to the era of 10 billion box office.

Is the "strength" of the diesel version of tank 300 big? Look at the latest comparative evaluation of overseas bloggers

Source: car chat area

Australian bloggers revealed that the local Great Wall diesel version has been reported for sale, and the braking traction and load capacity of the car will be improved.

According to the approval, the diesel version of the new car is expected to be listed in Australia from January to March 2025. The car will have 3000 kilograms of braking traction, which is 500 kilograms higher than the existing hybrid and gasoline versions.


The improvement of braking traction makes the diesel version of Tank 300 closer to other SUV models with trapezoidal frame, such as Mitsubishi Jinchang and Toyota Crossover with traction of 3,100 kg, and Ford, Toyota and Isuzu with traction of 3,500 kg.

Based on the confirmed gross vehicle mass (GVM) of 2,880 kg and the estimated kerb mass of 2,280 kg, the load capacity of the diesel version of Tank 300 is estimated to be about 600 kg, compared with 397 kg for the gasoline version and 420 kg for the hybrid version.

Load capacity refers to the extra weight that a vehicle can bear besides its own weight, including passengers, luggage and accessories, etc. The calculation method is GVM approved by the factory minus the curb weight.


Great Wall Australia will announce its official details, including the official load capacity, before the launch of the 300 diesel version of the tank in the first three months of 2025.

As mentioned above, the diesel version of Tank 300 will be equipped with the same 2.4-liter turbocharged diesel engine as the latest Cannon and Cannon Alpha pickups, with a power of 135 kW and a torque of 480 Nm, equipped with a nine-speed torque converter automatic transmission and a four-wheel drive system.


This system will share technology with the hybrid and gasoline models listed in Australia in 2023.

According to the new vehicle energy efficiency standard (NVES) which will be implemented in Australia from July 1st, 2025, the diesel version of Tank 300 meets the category of "heavy off-road SUV" due to the improvement of braking traction.

After the diesel version of Tank 300 falls into this category, its upper limit of carbon dioxide emission in 2025 is 210 g/km, and according to this standard, the emission target of hybrid and gasoline versions regarded as "light off-road" SUV models is 141 g/km.


Although the hybrid and gasoline version of tank 300 has obtained a five-star ANCAP safety rating based on less stringent standard tests, it is not clear whether the diesel version can obtain this rating, or whether the change of mechanical structure requires further testing by safety agencies.

In China market, diesel version is not common in passenger cars, but in Australia, the main competitors of Great Wall Tank 300, including Ma Hengda, Mitsubishi Pajero Jinchang, Isuzu Ranger, Ford Roadwalker, KGM Ssangyong and Toyota Crossover, almost all use diesel, while Jeep is one of the few models that still only use gasoline.

According to the news, ZEEKR OS 5.0 was tested in Krypton 001, and the car demonstration flowed out.

On July 4 th, the news said that Krypton 001 was testing ZEEKR OS 5.0, and the car demonstration was exposed.

IT House learned from the video that ZEEKR OS 5.0 will add right navigation map display, HUD navigation map switch, music display cover and lyrics, screen off function, screen projection function, DOW opening warning, sentry mode, etc. The display layout of HUD is optimized, and only road information such as vehicle speed, lane distribution and speed limit is displayed when navigation is not in progress.

It is worth mentioning that the brand Krypton delivered 10,620 vehicles in June, and Krypton 001 won the championship of more than 300,000 pure electric vehicles. The 2023 Extreme Krypton 001 recently launched a limited-time car purchase right, and the WE version presented an optional fund of 28,000 yuan; WE version 86kWh battery upgrade lightning switching intelligent four-wheel drive system; ME version upgrades high-performance air suspension package; YOU version upgrades Z?Sport advanced sports suit, with free charging rights for life/120,000 points.

At the same time,Extreme Krypton 001 OS 4.3 will start full push on July 6.ALC shift lever is open for all users to try in 0 yuan.

Fan Bingbing was beaten by his mother when he was young and rebellious, and only took a bath once a week (Photo)






Fan Bingbing childhood







Fan Bingbing and mother


  Fan Bingbing, who frequently attended charity dinners with his mother and appeared in the media, revealed in an interview with host Li Jing recently that he was often beaten by his mother as a child due to his stubborn temper.


  Two or three years old can recite children’s songs


  Although Fan Bingbing has now joined the ranks of domestic first-line actresses, in an interview, Fan Bingbing revealed that he used to be a Cinderella who lived in a bungalow and could only take a bath once a week.


  Speaking of his rebellious time when he did not listen to discipline, Fan Bingbing lamented "poor parents’ hearts": "I have been learning piano under the guidance of my parents since I was a child, and I have a strong desire to express myself. When I was two or three years old, I begged my mother to tell stories every night, and the next day I repeated the story to my mother again. I think this is my mother’s deliberate attempt to cultivate my language expression ability. When I was two or three years old, I could recite a lot of children’s songs."


  Disobedient and beaten by mother


  Since she was a child, she has practiced piano and cultivated her body and mind. Fan Bingbing revealed that her parents had long been conscious of cultivating her into a lady of temperament, but because of her stubborn personality, her mother has also strengthened her discipline. "My mother hit me because she really did it. First, because I have a very skinny personality, and second, because she is more irritable, she picks up whatever she picks up. Five or six clothes racks are stacked together, and they will break when they are smoked. I don’t know if it is inferior or too ruthless, and every time I leave a scar on my body."

Compact family car three cars compete for hegemony, and the new Qin EV rides the dust!

Under the epidemic situation, health and safety have become the top priority of all needs, and based on the consideration of travel safety, people are increasingly inclined to travel by car. Not long ago, the lottery results of the new passenger car were announced. For the lucky ones who just got the index, how to choose a reliable car is very important.

As the main model in the market, the epidemic prevention and sterilization capabilities of brand new, BEIJING EU5 and brand new have reached the professional level, and brand new has become the leader in the compact pure electric family car market with its strong and numerous fan base. So if you want to choose a safer, stronger and more practical one among these three cars, who will be the better option?

Who is the strongest in protecting health and professional sterilization and antivirus?

To be healthier and safer, we must first have stronger sterilization and antivirus ability. The newly equipped three-layer high-efficiency composite filter screen can filter dust, harmful gases, PM2.5 particles with a diameter of > 0.3 μ m up to more than 90%. Its filter screen consists of non-woven fabrics and chemical fibers, and is made by melt-blowing process, which can better filter droplets and particles with diameters greater than 0.3 μ m that germs often attach to, thus effectively blocking germs from entering the car. In addition,BYD’s self-developed high-efficiency filter has obtained the first batch of "CN95" certification of the highest level of automotive air-conditioning filter filtration, and will be fully equipped with this system for more old models in the future to further improve health and safety performance.

At present, the filtration system carried by EU5 has been upgraded on the basis of filtering pollen and PM2.5; On the other hand, a UVC deep ultraviolet optical anti-virus system was installed for Ei5, but there are still concerns that "ultraviolet anti-virus will have adverse effects on human body" in the market at present. It is not difficult to see that the new health care is more professional and leading.

Guarding safety, the brand-new Qin EV power battery has a 16-year accident.

If health is a higher demand of consumers, then the demand for vehicle reliability is the basic demand of all consumers. In the world, this basic requirement includes the reliability of endurance, the reliability of battery, and the reliability of the overall performance of the vehicle, etc. If the technical performance of any aspect is not strong enough, there is no way to talk about safety, and no one can trust a brand of new energy vehicles with frequent vehicle spontaneous combustion. 

From the comparison of the above figure, the brand-new battery has higher energy density and can store more electricity per unit volume, so its comprehensive endurance is stronger, and at the same time it can have more room for lightweight.

While continuously improving the energy density, a 7-dimensional and 4-layer safety matrix has been built for brand-new power batteries, which "comprehensively tests the safety of single batteries, modules, battery packs and systems from the aspects of reliable connection, high-voltage protection, collision, overcharge, internal and external short circuit and thermal runaway; The high-voltage system has undergone five tests: leakage detection, power-off protection, misoperation protection, active discharge and passive discharge, and the whole vehicle has undergone extreme cold and heat tests, which fully guarantees the safety of the battery. "

If these terms seem hard to you, then the accident in 16 years will definitely make you easily realize the reliability of the battery.The accident in 16 years first benefited from BYD’s technical advantages in battery safety design.In order to avoid the thermal runaway of the battery caused by the short circuit in the battery caused by the contraction of the diaphragm at high temperature, a ceramic diaphragm with more high temperature resistance was developed. In order to cope with high and low temperature environment, prevent overcharging, improve fast charging safety and flame retardant, etc., many special additives are added to the electrolyte solution of the battery cell on the basis of the original solute and solvent to ensure the stability under various complex conditions; In addition, in order to protect the safety of the battery cell, a mechanical device, including a CID device and an explosion-proof valve, is arranged on the shell of the single battery cell to prevent overcharging. These technical advantages are integrated into the battery intelligent temperature control management system, which is not only smarter, but also greatly improves the consistency and stability of products.The new Qin EV is equipped with BYD’s third-generation battery intelligent temperature control management system, which can make the battery in the most efficient working range at various ambient temperatures, greatly improving the battery life cycle performance, life span and safety.

Secondly, the accident in 16 years can be achieved thanks to all the self-research and self-production of the three power systems. Compared with peers, it has higher integration, more advanced consistency and integrity, and a stronger degree of systematization.BYD’s brand-new Qin EV efficiently integrates the motor, electronic control and transmission, which reduces the volume by 30% and the weight by 25%, while increasing the power density by 20%.

EU5 and Ei5 are made in Contemporary Amperex Technology Co., Limited, and although they have passed the battery safety test, the integration is not enough, and the consistency and integrity of products are different, so the stability performance in practical use is relatively average. For example, the dry-wet separation thermal management technology of batteries carried by EU5 is said to be effective in preventing combustion and explosion, but an EU5 exploded in Zhenjiang last September. At the same time, there are also car owners who feedback Ei5 battery failure on the car quality network.

In addition, the brand new has a stronger fan base. As of now,Qin series models have accumulated more than 200,000 fans, and have made remarkable achievements in sales volume, quality and word of mouth.,At this point, the brand-new performance is more ahead of. As a model, last year, some car owners reported on the Internet that it had a nominal battery life of 410 kilometers and actually traveled at full power for 210-220 kilometers. Therefore, in terms of endurance authenticity, brand-new is more reliable.

From the above comparison, we can see that a truly safe new energy vehicle is armed from the inside out to the "teeth", and the basis of this "armed" is the comprehensive technical strength, and the brand-new safety is based on this. It is this technical strength that has been recognized by more peers. It is said that the new factory invested 8.5 billion yuan will be used to produce and cooperate with products under the e platform.

Summary:

Changes in consumer demand after the epidemic will require higher safety, health and intelligence. Choosing a healthier and safer car will become one of the core needs of consumers around the world. At the same time, a truly leading new energy vehicle is that it understands the needs of consumers enough, and the leading comprehensive strength and proper configuration are the real masters. In the field of new energy compact family car, brand-new has really set a benchmark!
