＂Anti-wolf spray＂ is a contraband used by ＂wolves＂. Who will take care of the ＂online shopping＂？

　　Blowing darts, hunting bows, electric batons, tear gas, anti-wolf spray … … Can these goods that can cause harm to the human body be bought and sold at will?

　　"These are all controlled devices. According to relevant national laws and regulations, sales of controlled devices need to be filed with the public security department to obtain corresponding licenses." The relevant person in charge of Chaoyang Branch of Beijing Public Security Bureau said.

　　However, the reporter found that although these prohibited items and control devices are hard to find in physical stores, they are easy to "find" on the Internet.

　　Contraband can be bought on e-commerce platforms and search platforms.

　　Most consumers don’t know that anti-wolf spray is a prohibited item. "It can make the bad guys lose their mobility in a short time without causing permanent damage. I think it is quite reliable. Why should it be banned?" Li Mo, a bank employee in Beijing, asked.

　　In fact, anti-wolf spray may not prevent wolves, but it may be used by "wolves" to infringe on others. In Dongzhimen Station of Beijing Metro Line 2 in 2014, a passenger sprayed anti-wolf spray on the explosion-proof blanket, causing many passengers to feel unwell. In Guangzhou, Xi ‘an and other cities, there have also been incidents in which anti-wolf spray caused public disorder. As early as 2012, Taobao formulated the Catalogue of Prohibited Goods and Information, which explicitly prohibited platform merchants from selling such control devices.

　　Li Mo said that she searched for anti-wolf spray on Taobao, and the website would prompt "According to relevant laws, regulations and policies, it cannot be displayed ‘ Anti-wolf spray ’ Related baby. " When searching in JD.COM Mall, you can’t find the anti-wolf spray directly, but other anti-wolf devices of various colors will pop up in the window, such as the anti-wolf alarm, and it is specially marked as "Non-spray". Li Mo’s experience is: "‘ Non-spray ’ It is the cover for merchants to cope with inspections. If you contact customer service again, you can definitely buy what you want. "

　　According to this method, the reporter asked an outdoor equipment store on the platform of JD.COM Mall, and the other party replied: "Take a wolf alarm in 59 yuan, and we will note that we will send a wolf spray." Another outdoor sports store customer service offered to add QQ or WeChat for details. After the reporter added QQ, the other party sent a letter: "Lipstick anti-wolf spray 45 yuan postage."

　　In addition, the reporter entered "anti-wolf spray" on Baidu, 360 and other search platforms, and most of them were websites that blatantly sold anti-wolf spray, with various models, appearances and types, and pictures and texts were very detailed.

　　Online sales of prohibited items have been repeatedly banned, and there is a blind spot in multi-head supervision.

　　Why are online sales of contraband prohibited? What are the difficulties in supervising the online sale of contraband?

　　"The network is open, virtual and convenient, which objectively provides living space for prohibited items." Jing Linbo, director of China Social Science Evaluation Center of China Academy of Social Sciences, said.

　　"There is no unified catalogue for online contraband, which makes supervision more difficult." Jing Linbo said. What are the contraband altogether? Actually, it’s hard to say clearly. For example, simulation guns, both plastic toy guns, prop guns, etc., also have simulation guns with firing functions similar to guns. According to the Identification Standard for Simulation Guns, the shape and color are the same as those of standard guns, and a piece of paper can be punched in a distance of 5 to 7 meters. Toy guns with standard gun structures belong to simulation guns and will be banned by the police. Take dart blowing as an example. There are both children’s toy-style sucker darts and metal darts that can be sharpened or even coated with anesthetic ether. The latter can stun small animals and undoubtedly cause harm to people. However, there is no "standard for determining dart blowing" that stipulates which darts should be banned.

　　"Online sale of contraband involves food and drug, industrial and commercial administration, public security organs and other regulatory authorities. In recent years, with the rapid development of cross-border e-commerce, the supervision of online sales of contraband also involves customs. In the case of multi-sector supervision, it is easy to have management blind spots, and how to improve the efficiency of coordinated operations is also a challenge. " Jing Linbo said.

　　Before the introduction of relevant laws, the platform party cannot evade its responsibilities.

　　The reporter found that it is also difficult to report the e-commerce that sells contraband and confirm the address of the business. The reporter called 12345 Beijing non-emergency rescue service center to report. The staff was willing to accept the report of illegal sales of prohibited items, but asked for the specific address of the merchant. The reporter could not find the address of the merchant on the e-commerce platform. The staff of the service center suggested that the reporter report to the public security bureau of the e-commerce platform. The reporter called the alarm desk of Beijing Yizhuang Economic and Technological Development Zone Public Security Bureau, where JD.COM’s headquarters is located. The other party said: "There are so many businesses on the JD.COM platform that we can’t check them unless we provide the address of the business selling contraband and report it to the local police station."

　　"It is difficult to supervise the online sale of prohibited items. The crux lies in the fact that the e-commerce platform and the search platform are not in place for the certification of the main qualifications of online stores and the filing of business categories. China urgently needs a systematic and complete law and regulation for online retailing, and clarifies the responsibilities of the platform. However, during the transition period when the law has not yet been promulgated, the platform side should not evade its responsibilities. " Jing Linbo said.

　　Since searching online for products such as darts and hunting bows, e-commerce platforms and search platforms have pushed such product information to reporters from time to time, and their "intelligent" penetration ability can be seen. This makes people lament: why don’t online shopping platforms use this "intelligence" to supervise the sale of contraband? For example, establish an accurate keyword screening system, refine category management, clearly define the product content and name under each category, and prevent one product from escaping the keyword search screening function … … Obviously, technology is not a "thing" to manage contraband. The key is whether you want to manage it or not.

With 50 million users and an annual revenue of over 1 billion, Fan Deng, a storyteller, uses the business achievements and user scale of the enterprise to fight against the arrogance and prejudice of

"This is our slogan, reading lights up life." Fan Deng said, pointing to the words printed on his T-shirt.

Fan Deng’s own life was actually lit up by reading.

Recalling the period when graduate students just graduated into CCTV, Fan Deng was very confused at that time, and his work pressure was great, his ability was not recognized, and his enthusiasm was nowhere to be displayed. "What if the program was shot again? What if I can’t afford the rent? " Fan Deng’s anxiety and insomnia are weighed down by realistic difficulties.

Rereading The Analects saved Fan Deng. He found that all the pains of contemporary people can be answered from this classic. As a student, the master of science and engineering who firmly believed that "learning mathematics and physics well and traveling all over the world are not afraid" suddenly found the key to solving the pain of life. It turns out that ending exam-oriented education and taking up jobs is not the end of learning, but the beginning of lifelong learning.

Later, whether it was parenting, starting a business or managing a company, Fan Deng felt that reading helped him avoid detours. He teaches leadership in EMBA class and earnestly "Amway" good books to students, but few people actually read them. Then tell the book to everyone, and those who are willing to listen will pay to join the group. As a result, he found this model very popular, which is the embryonic form of "reading in Fan Deng".

2022 is the ninth year of Fan Deng’s study. The number of APP users evolved from the book club has exceeded 50 million, and it is stable and profitable.

And Fan Deng, who is lit up by reading, can light up the readers by telling books?Learning and seeking knowledge undoubtedly benefit people a lot. Can you really make people learn and change by spending 365 yuan to buy a member to listen to a book for one year?

Fan Deng won the "Knowler of the Year" trophy.

At the end of the year and the beginning of the year, Fan Deng came to the release site of "New Weekly’s annual cutting-edge list" to win the trophy of "Know the Molecules of the Year". After receiving the award, Fan Deng accepted an exclusive interview with a reporter from national business daily (hereinafter referred to as NBD).

Read books to others.

I knew it was a business model from the beginning.

In 1995, Fan Deng, a junior majoring in materials science at Xi ‘an Jiaotong University, attended a summer camp, during which a Hong Kong senior asked him, "Have you read The Analects?" Fan Deng said, "No, I’m afraid I can’t read it?" The senior recommended him to read The Analects of Confucius.

The Analects of Confucius does not talk about "learning from time to time" at the beginning, but "the origin of the world is light with two arms, so why bother to connect with the city in the world" (who would exchange losing his arms in order to get the world? The fame and fortune in the world, why do people take it so seriously? ）。 This book helped Fan Deng knock on the door of The Analects. Who would have thought that the Analects of Confucius later became a lamp to illuminate Fan Deng in the dark. He was born in science and engineering and worked as a CCTV host, and found his real enthusiasm and business opportunities in the lecture.

Reading lights up life, which is slogan who studies in Fan Deng.

NBD: As a person who loves reading, how did you first come up with the form of telling books?

Fan Deng:It is anxious to see others not reading. My own habit is to look for books to read when I encounter any problems. If I can’t host the program, I will read the books that host the program. Read books with children without taking them; Read leadership books without taking the team. "Studying in Fan Deng" is my first time to start a business. If I can’t start a business, I’ll read a business book.A question, after reading more than a dozen books, can basically be understood. I rely on reading for parenting, making money and management, and reading has benefited me the most.

Later, when I was a teacher in a university, I taught EMBA classes and found that the books recommended to students only bought and didn’t read. I will share the books I have read with them as PPT, but they don’t even read PPT, so I will start a WeChat group and talk about 50 books a year. The annual fee for joining the group is to press the voice button for 60 seconds and 60 seconds.

NBD: What node can it be found to be a business model?

Fan Deng:From the beginning, I knew it was a business model, because it was completely in line with the structure of an enterprise, and the services it provided could help people solve problems. Its marginal cost of communication was very low, and there was a repurchase rate. The CEO of our company is an EMBA student in the first batch of WeChat reading groups.

NBD: You studied materials science in college, management science for graduate students, movies for doctors, debating competitions, being a host, being a university teacher, and now you are starting a business. It seems that every choice has not failed in the secular sense, and you are also very confident. Are these brought to you by reading? Or because of what?

Fan Deng:These are all after-the-fact interpretations, and they can also be understood as failures. You said that I had a smooth trip, which was just your projection, not the fact. The fact is that it doesn’t matter whether it is smooth or not, and there is no wrong choice. To understand the shaping of life by randomness. I was admitted to the university because of the family environment of science and engineering. My father instilled in me "learn math, physics and chemistry well" since I was a child. Graduate students are all graduate students with good grades, so I should take one. The doctoral degree is to solve the Beijing hukou. Are not designed in advance or particularly forward-looking.

But one thing, I never gave up trying, never gave up studying, and never said, "Come on, I’ll just get along." When I entered CCTV, I couldn’t do many programs I wanted to do, but I exercised a lot of ability in the process of making samples.Therefore, life is not clear about success or failure, and it is good to enjoy your life.

Listening to books is unreliable?

It is the arrogance and prejudice of intellectuals.

Fan Deng believes in the power law. As long as 1,000 loyal members are willing to pay for his knowledge and recommend it to their families or employees, it will be a success. Some members have further become the agents of studying in Fan Deng. This company does not need to advertise, and people and word of mouth have become the natural distribution channels of knowledge products in Fan Deng.

NBD: Which is better, listening to books or reading by yourself?

Fan Deng:For most people, listening to books is much better than reading, because the books I talk about are basically books that are not easy for everyone to understand. Listening to books can sort out the context more quickly and enter this field.

When we were growing up, all teachers did one thing-telling books, but who spoke better. So you don’t have to be resistant to new things,Many intellectuals feel that listening to books is unreliable at first, and they think how good they are at reading. This is a kind of arrogance and prejudice.

NBD: How did the price of 365 yuan a year come from?

Fan Deng:It’s easy to remember that 365 yuan is one yuan a day, and it’s not too much to charge one yuan a day. We have a product called "Fan Deng tells the Analects of Confucius", and we set up a punch-in training camp, that is, we pay 300 yuan to join the punch-in training camp. If we don’t stop punching once, we will refund the fee.

This is actually a charging mode, but the completion rate of this punch-in training camp can reach 96%, and almost everyone has to refund their fees in the end, but I am particularly happy because they followed me to learn the Analects from beginning to end. Many messages said that if you don’t punch in on the last day, you will find it useful to learn and don’t refund your fees. It shows that there are many people who are willing to learn, and it is enough for us to do business with these people.

NBD: Will this pricing change?

Fan Deng:I don’t know, maybe it’s free, but I don’t tend to be free. Free things just spend your time. And because it’s all free, you will only choose the part that interests you, but follow me, you can hear physics, entrepreneurship, history … and books that you think have nothing to do with yourself, and you won’t take the initiative to read.The essence of education is encounter with knowledge, and search and independent choice lose the possibility of encounter.

NBD: What are the criteria for choosing what books to talk about?

Fan Deng:We hope that more people will read better books and not make decisions based on the number of hits of this book. Because the user seems to vote with traffic, he thinks he likes listening to parenting books, but if he is pushed parenting books for a long time, he will not go with you, and he will feel boring slowly. We should explore the potential of everyone. People who like to listen to parenting can also understand philosophy and physics. This is what Confucius said, "A gentleman is not a tool", and our content is a completely anti-Internet algorithm.

Some time ago, we also put on the shelves the content of "The Power of Calculus". Many people think how dare you talk about such an unpopular content of calculus? I just think that it is precisely because there are few people who know calculus that we should talk about this book and let everyone know how important calculus is. The CEO of a big platform often chats with me, saying how do you sell serious content so well? Isn’t it just for entertainment and people who eat melons who like to watch it? I don’t think so. I think everyone has an upward pursuit. If I make those serious contents wonderful and easy to understand, someone will be willing to pay.

It’s good to be listed.

Can’t go public,It doesn’t hinder doing what should be done.

When you open a web page and search for the term "Fan Deng", the most common content that appears in your field of vision is "annual income of 1 billion yuan". In fact, this number is still increasing. In the "double 11" in 2021, Fan Deng made a membership promotion, and sold a total of more than 300 million membership fees a week. During the reading festival, the sales volume exceeded 400 million yuan. In any era, scholars who "will make money" are often the most able to stimulate the public’s nerves.

NBD: At present, the most praised by outsiders for studying in Fan Deng is that the annual income exceeds 1 billion yuan. Is this figure accurate? What is the revenue structure?

Fan Deng:We are a very transparent company, and we do not hide the company’s revenue figures.In 2020, it will be about 1 billion yuan, which will nearly double the growth during the epidemic.

We are actually a company that spreads knowledge with my personal IP brand as the core. In terms of revenue structure, at present, the biggest revenue segment of the company is definitely Fan Deng’s subscription products, "Listen to me for 365 days", with a large number of subscribers and a high renewal rate. Many users have followed it for 78 years, and this part of the revenue is very stable and has been growing slowly, accounting for 60%~70% of the total revenue.

In addition to my products, there is also "Extraordinary Intensive Reading", where experts from all walks of life are invited to give lectures, such as professors of philosophy department of Fudan University, parenting experts, partners of McKinsey and so on. In addition, we also have course business, publishing business and offline bookstore. We published about 100 kinds of books in 2021, and there are more than 200 offline bookstores nationwide.

NBD: Is this growth rate within expectations?

Fan Deng:Actually, it’s a little slower than I expected. Exponential organizations are growing very fast, and it is normal to reach hundreds of millions of users in almost three or four years, such as Tik Tok. Reading in Fan Deng is published by traditional education. Compared with these industries, it will appear that we are fast, but it is slow compared with the Internet.

NBD: In July, 2021, Shanghai Soybean Network Technology Co., Ltd., the main operator of Fan Deng Reading, completed the latest round of financing. Is it preparing for the listing plan?

Fan Deng:We just want to do the right thing, it’s good to be listed and we can develop further; We can’t go public, and it doesn’t prevent us from doing what we should do.

Personal IP growth will not slow down

Maintain anti-vulnerability and ensure sufficient cash flow.

Knowledge economy is like a besieged city. In the besieged city, countless fans regard Fan Deng as an idol of knowledge and are willing to pay for it; But outside the besieged city, once financing, it will always face the scrutiny of the capital market-how to eliminate the uncertainty caused by high dependence on personal IP and the sale of "non-standardized" products. When dealing with personal brands, some people make "retreat arrangements", while others choose "not to slow down".

NBD: For content companies that are highly dependent on personal IP, there will be many concerns in the capital market. What do you think?

Fan Deng:Our products are not personal IP products, but intellectual property products. If I don’t talk about new books now, the company’s income will also exist, because so many books I have talked about before are subscription products with long-term existence and long-term revenue.

Although we are a weekly program, there are 700 people in our team. In addition, personal IP is only the starting point of the company. Now we are developing a matrix product structure, with our own publishing business and offline bookstore, as well as our own shopping mall, curriculum business and vocational skills training school.

The rapid development of science and technology will replace many people’s careers. Since we see this trend, we should do vocational skills training. For example, it is difficult for take-away workers to deliver takeout all the time in the future, so we should create some jobs that are more valuable as they get older.

NBD: With the development of other businesses, the revenue structure of the company will be more balanced?

Fan Deng:Although the income from listening to books accounts for the largest proportion at present, the growth rate of other sectors is very fast, and it is certain that they will exceed the income from listening to books in the future.

We will not deliberately slow down the growth of other businesses to cater to that ruler, nor will the growth of my own IP slow down.But we should also do other businesses faster, so that the company can develop healthily.

NBD: What do you think of the trend of knowledge payment?

Fan Deng:The market develops periodically, and it seems that knowledge payment is still a good track at present. While referring to the market, the company will also focus on the business it wants to do.

My wife runs a beauty salon. One day, she said that she saw an article analyzing the trend of the medical and beauty industry, so I said it was unnecessary. First of all, what you are doing is not the whole medical and beauty industry, and that trend has nothing to do with you; Secondly, that trend may not be accurate; Third, seeing more trends affects your initial heart, and the trend says that you don’t make money, then you are shaken?So we only do what we have to do, while maintaining anti-vulnerability and abundant cash flow.If there is a bigger black swan incident, which leads to a major setback for the company, we still have a larger choice and may even become better.

Reporter’s Notes |

When Lecture Room first appeared, there was also controversy.

The emergence of new things is always accompanied by controversy. When the lecture room appeared, there was a lot of controversy. Can serious knowledge be told in this way by laughing and cursing?

However, an intellectual said it well, whether talking about the Analects of Confucius or Historical Records, at least it stimulated more ordinary people’s interest in understanding and getting close to historical classics.

In the digital age, the ways of knowledge dissemination are becoming more and more diverse. Whether reading or listening to books, the effect of knowledge payment on everyone varies from person to person.

However, under the trend of entertainment first, it is a good thing that some people are willing to promote reading and serious reading, create diverse content and innovative reading forms, so that more people are interested in reading and users have more choices.

You can buy it for 139,800 yuan, the MG compact car.

Nowadays, there are many kinds of cars, and all kinds of models are dazzling. At this time, we should proceed according to our own reality, and the right one is the best. The level of configuration determines the competitiveness of a car to a certain extent, as we said in this article. Let’s look down with Xiaobian.

First of all, from the appearance, the front of MG4 EV is relatively simple and looks very fashionable and simple. Headlights are very young and meet the "taste" of young consumers. The car is equipped with LED daytime running lights, automatic opening and closing, delayed closing and so on. Coming to the side of the car, the car body size is 4287MM*1836MM*1516MM. The car adopts unique lines, and the car body looks very solid. With large-sized thick-walled tires, the overall visual effect is very fashionable and sporty. In the design of the rear end, the rear end echoes the front face from a distance, and the taillights give people a very simple feeling. Overall, it is still relatively fashionable and simple.

When coming into the car, the interior of MG4 EV looks very comfortable and easily touches the hearts of young consumers. The steering wheel of the car is very atmospheric in shape, and it is equipped with functions such as manual steering wheel up and down+front and rear adjustment, which gives a good grip experience. Take a look at the central control, and with the 12.3-inch touch-sensitive LCD central control screen, the interior design is quite layered and looks beautiful. The dashboard and seats give people a good feeling, too. Let’s take a look. The dashboard of this car presents a domineering design style and looks dignified. The car adopts imitation leather seats, equipped with functions such as electric seat adjustment and seat proportion tilting, and the overall ride feels soft and comfortable.

The MG4 EV is 125KW, the total torque is 250N.m, and the maximum speed is 160 km/h.

The car is equipped with driving mode selection, remote control key, rear wiper, traction control (ASR/TCS, etc.), Bluetooth /WIFI connection and other configurations, which fully ensures the convenience and comfort of the car experience.

After reading the above description, Xiaobian will make a summary. This car has been introduced almost before, and I believe many users who buy a car have taken a fancy to its comfort and practicality.

At the end of the holiday, the return passenger flow increased significantly, and many measures were taken to ensure smooth travel.

The National Day Mid-Autumn Festival holiday entered the last day today, and since yesterday, the return passenger flow has increased significantly. The holiday is coming to an end, and in order to cope with the peak of passengers’ return journey, the railway has adopted the way of adding trains to enhance its capacity. Specifically, according to the statistics of Yinchuan Passenger Transport Section of China Railway Lanzhou Bureau, the long-distance passenger flow returning from Ningxia in these two days is mainly concentrated in Beijing, Shanghai, Guangzhou and Hangzhou, while the short-distance passenger flow is mainly in Lanzhou, Xi ‘an and Qingyang.

In this regard, according to the transportation capacity adjustment plan, Yinchuan Passenger Transport Section reconnected and added several pairs of trains, with a total of 51.5 pairs of trains undertaking the transportation task, including 39.5 pairs of high-speed trains and 12 pairs of ordinary trains, to meet the travel needs of passengers to the maximum extent.

There is a peak return trip at high speed, and the "police-insurance linkage" ensures smooth travel.

Roads around the country also ushered in the peak of return passenger flow these two days. Hebei and Shandong respectively set up "police-insurance linkage" convenience service stations and "midway charging stations" at high speed to provide convenience for returning vehicles and people.

On October 7, the traffic in Hebei Province began to turn from major scenic spots to expressways. The Hebei high-speed traffic police predicted that on the last day of the holiday on October 8, the traffic on the main highways around Beijing and Tianjin in Hebei Province would remain at a high level from morning till night.

In order to cope with the peak return journey, the Traffic Management Corps of Hebei Provincial Public Security Department strengthened the frequency of road police patrol and video patrol control during peak hours and key sections. In addition, 83 "police-insurance linkage" convenience service stations have been set up on the expressway network in Hebei Province to facilitate the people to handle traffic accidents nearby and ensure the smooth passage of expressways.

In the Pingdu-Weifang section of Shandong Rongwei Expressway, the reporter saw a "midway charging station", which was not built in the service area, but in a rest area between the two service areas. This is specially set up in the local area to cope with the peak charging pressure of holiday travel and return trip. It is equipped with 5 charging piles and 10 charging guns, which can provide fast charging service for 10 new energy vehicles at the same time.

Lin He, an electric power worker: Through big data analysis, we chose to build a charging station at this key node. We also established an emergency support mechanism, with double operation and maintenance personnel on standby 24 hours a day. Once the equipment fails, we will rush to deal with it as soon as possible.

Civil aviation ushered in the peak of return journey, and many measures were taken to ensure travel.

In Taiyuan, Shanxi, in order to cope with the peak of return passenger flow, the local airport department has taken various measures to ensure the safe and smooth travel of passengers.

Yesterday (October 7th), there was an endless stream of passengers in the terminal building of Taiyuan Wusu International Airport. Everyone went through the check-in and baggage check-in procedures in an orderly manner. In order to cope with the peak, the airport has continuously introduced convenient services, dynamically opened check-in counters, opened late arrival passenger passages, and sent more staff to provide guidance and consultation. In addition, the airport also cooperates with airlines to optimize the delivery of transportation capacity. At present, the passenger flow of routes from Taiyuan to Shanghai, Kunming, Guangzhou, Chengdu, Hangzhou and other cities is relatively large.

What are the routines of I like you？ Zhao Lusi pushed too hard, and Lin Youyou had more slots for women.

After the broadcast of "I like you", it quickly occupied the hot search. This sweet pet dinner drama let the audience see the long-lost delicious food on the tip of the tongue, and also let the audience see the romantic bridge in Korean dramas. In particular, the ending song is simply a visual sense of Korean drama, and the model of Ouba+nervous little girl.

Tencent video of "I like you" has been played 390 million times, which is a good start. Major entertainments have given the play a good rating from the media. Gu Shengnan, played by Zhao Lusi, was a fine performer as soon as he appeared, and Lu Jin, played by Lin Yushen, staged a famous flour scene, as well as a famous coat scene.

The most direct thing is that Lu Jin and Gu Shengnan compensated for the car. Gu Shengnan cooked food to pay off debts, and they all smelled sweet taste through the screen. Although it is paying debts with food, it is actually an indirect cohabitation model for couples.

"I like you" is adapted from the blue-and-white novel "I finally wait for you". The play mainly tells the story that Gu Shengnan, who is very sad, has become more and more proficient in cooking after meeting Lu Jin, a poisonous tongue. Lu Jin, who eats food, is attracted by the food of Gu Shengnan, a witch. Thus, two people wrote a romantic love myth. Love may be late, but it will never be absent.

I like you scored 7.3 on Douban, which was 0.3 higher than the movie version of Takeshi Kaneshiro Zhou Dongyu’s Like Me, and the result was quite good.

Zhao Lusi’s overexertion is embarrassing, and Lin Yushen’s acting skills in man show are short-board.

Zhao Lusi, with her "Chen Qianqian in Rumor", became popular all over the country and jumped to the top. She is definitely the queen of idol drama. However, if you look at "I like you" carefully, you will find that there is no breakthrough in her acting skills, which is embarrassing, and she has not performed Gu Shengnan’s ghost horse elf at all.

In the play, Zhao Lusi gives the audience the feeling that he has been playing a character similar to Chen Qianqian and dancing in minutes. Xiao Bian’s watching the first ten episodes is like watching an idol drama in Taiwan Province 20 years ago. Especially in that crying scene, I almost cried out the sound of boiling water.

Lin Yushen stepped into the "uncle circle" by virtue of Lu Jin, whose personality is overbearing president+man show+manly+melancholy prince. Lin Yushen performed man show of Lujin and the overbearing president, but he didn’t perform masculinity. Therefore, he looks greasy. Comparing his Lu Jin with Takeshi Kaneshiro’s, LinYu’s Lu Jin lacks charm.

"I like you" has a strong sense of CP, and many kissing scenes are also very sweet.

In the original work, Gu Shengnan and Lu Jin are the CP of Uncle and Lori, and the collocation of LinYu Shen and Zhao Lusi in the play is also highly praised. The tacit understanding between the two people and those famous scenes allowed the audience to walk into the real fragrance scene in minutes. Sister Ruth and Uncle Lin Yushen are also regarded as immortals CP in idol dramas.

There are so many kissing scenes in "I like you". A careful analysis of the kissing scenes in the play will find that it has contributed to the feelings of the two. In the first episode, Sister Ruth left a bad impression on Uncle Lin Yushen. Gu Shengnan wanted to escape and had to tell Lu Jin in broken Korean. I didn’t expect Lu Jin’s Korean to match the authentic Korean. After this battle, Gu Shengnan lost.

The turning point in the warming relationship between Gu Shengnan and Lu Jin was that Gu Shengnan accidentally kissed Lin Yushen, and both of them felt the wonderful power of love. Later, they almost kissed in the corridor, either the lights were on or the uncle appeared, the atmosphere was destroyed and they didn’t kiss. It is a pity to be the host and hostess, and it is even more regrettable to be the audience.

Female three as saboteurs, disgraceful means comparable to Nothing But Thirty Lin Youyou.

In every play, there is a girl who is shouted by everyone. They are always saboteurs. In "I like you", there is a stalk in the general idol drama, that is, the third girl acted as a saboteur, and she was unkind when she appeared on the barrage.

Riemann, played by Li Qian, is the No.3 female in the play, which is also regarded as the villain in the play. She has a crush on the hero Lu Jin. As soon as Riemann appeared, he arranged a full schedule for Lu Jinan, and he also angered Gu Shengnan’s cooking skills in front of Lu Jin. This young lady was besieged by hundreds of millions of netizens as soon as she went online.

Li Qian once played Song Yuzhi in "The Tale of Two Dragons in Datang", but her acting skills were ok, and she didn’t suck powder at all.

Riemann is a man who uses means to destroy the feelings of men and women, which is comparable to that of Nothing But Thirty Lin You You, and will certainly arouse the hatred of hundreds of millions of netizens.

Gu Shengnan’s girlfriends interpreted plastic sister flowers, and shameless+routines promoted the development of the plot.

Some girlfriends in film and television dramas are very tight, such as Zhong Xiaoqin and Gu Jia in Nothing But Thirty, Sang Tian and Xiao Rou in Girl in Armor, Cheng Lu, Tian Lei and Ding Shiya in Who Says I Can’t Get Married, etc., all of which show the audience the depth of girlfriends’ affection.

The girlfriends in "I like you" look fake. Gu Shengnan’s girlfriends are shameless and always follow Gu Shengnan’s routine. For example, her joint uncle made Gu Shengnan drunk, and the two escaped, and all the expenses were paid by Gu Shengnan. The opening scene of male and female names is that Gu Shengnan stood out for his girlfriends, and as a result, he got into trouble.

Gu Shengnan’s best friend can be called a plastic sister flower, and her only existence is to promote the development of the plot. For example, Gu Shengnan made a mistake for her and scratched Lu Jin’s car. After getting drunk under her routine, Gu Shengnan slept in Lu Jin’s bed, so that men and women met more and more times.

However, the girlfriend Zhao Di also played a real girlfriend love, that is, Gu Shengnan went to see Lu Jin with witch soup, and Gu Shengnan finally understood his sincerity to Lu Jin.

Zhao Di also got the address of Lai Lu Jin’s family, and Gu Shengnan successfully sent the cake. Although she met Riemann, she also found a hidden enemy around her, which is also a good thing for her. Wen/Yin Yi Jiu

[＂New Era, New Platform, New Opportunity＂] Tangjiazhai Reservoir ＂Deformation Record＂： From ＂Stinky Ditch＂ to ＂Scenic Area＂ in one year.

Cctv news(Reporter wanglili Chi-Kin Leung) Recalling the first time I saw Tangjiazhai Reservoir in Xi ‘an, Pang Zhengxi, general manager of the Ecological Construction Company of Shaanxi Environmental Protection Group, was still haunted. "The water is dark and smelly. If you stay around for a while, you will cry and even vomit."

Tangjiazhai Reservoir was built in the 1970s, and once undertook the irrigation task of thousands of acres of farmland in surrounding villages. Since Jiangcungou landfill was built less than two kilometers upstream in 1994, it was quickly polluted by landfill leachate and became a stinking ditch, which seriously affected the lives of nearby villagers.

In the first four months of 2017, as the key supervision project of the Central Environmental Protection Inspector Group, the Inspector Group requested Xi ‘an to rectify Tangjiazhai Reservoir polluted by leachate from Jiangcungou Landfill, and the rectification should be completed by the end of December 2017.

Shaanxi Environmental Protection Group Ecological Construction Company undertakes the task of rectification. Speaking of the process of the treatment project, Pang Zhengxi said frankly that the construction is very difficult in the face of the problems of sludge deposition and accumulation for more than 20 years and the inability of large machinery to enter the site at the same time. After comprehensive treatment projects such as solidification and landfill of sludge in the pond, anti-seepage treatment and construction of artificial wetland water circulation system, on April 16, 2018, the national environmental protection department officially completed the acceptance and cancellation of this project, and the former stinking ditch became a scenic spot today.

Tangjiazhai Reservoir Management is only a project case of Shaanxi Environmental Protection Group since its establishment. On May 11th, in the b3 Industry Hall of Xi ‘an Qujiang International Convention and Exhibition Center, Shaanxi Environmental Protection Group, as the only state-owned eco-environmental comprehensive enterprise in Shaanxi Province, held a centralized exhibition with the projects and products of its 19 subsidiaries and 2 regional branches.

The reporter saw that in the exhibition hall, there is not only a smart and environmentally-friendly atmospheric intelligent grid platform that integrates science and technology, but also an atlas of rural garbage and sewage treatment, as well as a kitchen waste processor closely related to life.

The relevant person in charge of Shaanxi Environmental Protection Group said in an interview that Shaanxi Environmental Protection Group has always focused on sludge treatment like Tangjiazhai, focusing on solving the problems of solid waste disposal, air pollution prevention and control, urban and rural environmental sanitation integration, etc. Now, they have set up the province’s first 15 billion yuan environmental protection industry investment fund, all of which are demonstrating their confidence in becoming stronger and better, and their determination to protect the green water and green mountains of Sanqin.

＂New Ten Articles＂ Released Hainan Tourism Warmed Up Rapidly

Haikou, China Broadcasting Network, December 8 (Reporter Lin Weiwei) On December 7, the State Council issued the Notice on Further Optimizing the Implementation of COVID-19 Epidemic Prevention and Control Measures to the Comprehensive Group of novel coronavirus Epidemic Prevention and Control Mechanism, and put forward the "new ten" epidemic prevention and control measures. That night, the novel coronavirus Epidemic Prevention and Control Command issued the Announcement on Optimizing and Adjusting Relevant Measures for Epidemic Prevention and Control, and timely adjusted the prevention and control strategies. Immediately after the release of the policy, the market was ignited, and the search and booking of travel and tourism products rebounded rapidly. Can Hainan’s cultural tourism market usher in a "warm winter"? The reporter conducted a survey for this purpose.

The search volume of travel and tourism platforms has suddenly exploded.

Winter is the peak tourist season in Hainan, and the further optimization and adjustment of the epidemic prevention and control policy has undoubtedly enhanced the enthusiasm of many tourists who are preparing to come to Hainan for the winter. After the news was released, the search volume of Hainan’s tourist destinations in the Mawei platform rose sharply, among which the search popularity of "Sanya Holiday" rose by 450%, making it the destination with the highest increase in instantaneous visit popularity in China.

According to the data of one-way travel, from December 7 to 8, the search volume of inbound and outbound air tickets in Haikou and Sanya increased sharply, and both increased by more than 200% within one hour compared with the same period of the previous day. Among them, the popular starting points for air ticket search to Sanya and Haikou are Chongqing, Beijing and Harbin.

The reporter learned from haikou meilan international airport and Sanya Phoenix International Airport that in the past two days, the number of people entering and leaving Hong Kong at the two airports has increased significantly. Judging from the current air ticket booking information, it is expected that the two airports will have a peak number of people entering and leaving Hong Kong from the end of December to New Year’s Day next year.

Hotel B&B booking day rose by about 10%.

"From last night to now, I have received nearly a hundred phone calls. I feel that everyone has been squatting for too long and can’t wait to go out and have a look." Wang Defen, head of the "Wild Grass Global Tourism Boutique B&B" in Lingshui Li Autonomous County, Hainan Province, told the reporter.

The B&B operated by Wang Defen opened in 2018 with 20 rooms, and the occupancy rate before the epidemic reached over 90%. In recent years, affected by the epidemic, the occupancy rate once dropped to less than half. Since December 5, many cities and counties in Hainan have successively issued announcements that foreign (returned) personnel in the province will no longer be classified and controlled, and the booking volume has risen instantly, and the occupancy rate has reached 100% in these days. "We have convenient transportation here and are close to the sea. It is the first choice for many repeat customers, so we are fully booked soon. Passengers who want to stay next need to book at least one week in advance. "

In addition to homestays, hotels in Hainan are also very sought after. Flying pig travel data shows that on December 7 and 8, the real-time search volume of hotels in Hainan increased by 30% compared with the same period of last week, and the search volume of hotels in Sanya, Haikou, Danzhou, Lingshui and Wanning all doubled compared with the previous weeks.

Tang Caixia, deputy secretary-general of Sanya Tourism Hotel Industry Association, told the reporter that the average occupancy rate of Sanya hotels was 33% from November 21 to 27 this year, down 3.8% from the previous month. On December 7, after further optimizing the epidemic prevention and control measures, the average hotel booking volume in the city increased by about 10% in a single day. At the same time, in order to attract tourists, major hotels and homestays have also planned various programs, and launched business trips, parent-child tours, couples tours and long-stay preferential packages to welcome the upcoming "peak season" of tourism.

"Judging from the current booking data, from December 18, major hotels and hotels in Sanya will usher in this year’s occupancy peak, and the average occupancy rate will reach about 80%, which is worth looking forward to." Tang Caixia said.

The choice of duty-free shopping and boutique tourism routes has increased.

In order to welcome the upcoming "peak season" of tourism, on December 7, Hainan launched the off-island duty-free New Year carnival season, which will last until February 5, 2023 (the fifteenth day of the first lunar month). During the event, six duty-free business entities and 12 duty-free shops on outlying islands in Hainan will launch various themed promotions to bring different duty-free shopping experiences to consumers.

Among them, stores and e-commerce sales platforms in Hainan Operation Center of China Free Group will launch preferential activities such as "China Free Handbag Festival" and "Buy and Give Full Reduction". Sea Travel Duty Free City will launch a series of marketing activities of "Sanya duty-free shopping first stop, making money when you buy it". Haikong Global Boutique Duty Free City will hold a series of promotional activities to welcome the Spring Festival and celebrate the anniversary with the theme of "He Xinchun+Celebration". Mission Hills Duty Free City in Haikou will offer discounts, multiple points and large gift certificates for many products. The National Free Sanya Store will hold a number of themed marketing activities such as "National Free Football Carnival-Meet the National Free Shopping Wonderful" and "Red Rabbit Exhibition to Welcome the New Year". Wangfujing International Duty Free Port will show consumers an interesting and diverse duty-free shopping space.

In the creation of tourist routes and products, cities and counties in Hainan have also made "big moves" to launch various forms of boutique tourist routes and products. Among them, Haikou launched a variety of theme activities from three aspects: tourism, culture and sports, and went to Hefei and Changsha to carry out tourism industry exchange meetings to attract tourists from Central China and East China to Haikou, so as to stir up Haikou’s winter and spring tourism market in advance. Sanya held a mobilization meeting to improve the safety production and service quality in the tourism industry at the end of the year and the beginning of the year, demanding that hotel room prices and tourist reception services should be done well, and actively planning to launch new tourism boutique routes. Changjiang, Dongfang, Wanning, Lingshui and other cities and counties combined with their own characteristics, launched a scenic tour, cultural tour, picking tour, surfing tour and other special tourism products.

Wang Suizhen, deputy mayor of Dongfang Municipal People’s Government, said that Dongfang, as the third largest coastal city in Hainan, is rich in tourism resources. In recent years, it has built several influential tourism cultural brands around outdoor sports, landscape, red culture and rural leisure, and will carry out various promotional activities in the near future to attract more people to travel to this beautiful coastal city, make it a "tourism cake" of the East, and promote the high-quality development of the tourism industry.

Two departments： all the central relief materials urgently allocated to Shanxi have arrived in the disaster area.

CCTV News:According to the WeChat WeChat official account news of the Emergency Management Department, the Office of the National Disaster Prevention and Mitigation Committee and the Emergency Management Department fully supported Shanxi to do a good job in disaster relief due to low temperature, cold wave, freezing rain and snow, and sent a working group to go to Yuanqu County of Shanxi Province to inspect the disaster situation on the spot. In the heating company, the power supply company, the government duty room and the affected communities, they gave guidance on emergency repair and recovery of power supply and heating, distribution of relief materials, and people’s living security, and tried their best to reduce the impact of the disaster.

The 10,000 pieces of cotton coats, 10,000 beds of quilts and other central relief materials and 5,000 sets of household emergency lighting equipment urgently allocated to Shanxi by the Emergency Management Department and the State Grain and Material Reserve Bureau have all arrived in the disaster-stricken areas such as Yuanqu, Wenxi and Changzhi on the 17th to ensure the safety and warmth of the affected people for the winter. At present, the production and living order of the people in the disaster-stricken areas in Shanxi is stable, and the power supply and heating in the main disaster areas in Yuanqu have been restored one after another.

Attack the big model! ByteDance AI software and hardware ecology is taking shape.

Science and technology innovation board Journal, December 18th (Reporter Huang Xinyi)At the Force conference in Volcano Engine, Tan Dai, president of Volcano Engine, announced that as of mid-December, the daily average usage of tokens of the bean bag universal model had exceeded 4 trillion, which was 33 times higher than that when it was first released seven months ago.

The previous list of monthly active users in the world shows that the MAU of Bean Bag App is close to 60 million, ranking second in the world after ChatGPT of OpenAI.

At the meeting, ByteDance officially released the visual understanding model of bean bags, the 3D generation model of bean bags, and the comprehensive upgraded universal model of bean bags, such as pro, music model and Wensheng diagram model. Among them, the input price of the visual understanding model of bean bags is only 3%, and one yuan can handle 284 720P pictures. The conference also announced that ByteDance will launch version 1.5 of the video generation model of Bean Bag with longer video generation capability in the spring of 2025, and the end-to-end real-time voice model of Bean Bag will be launched soon.

The science and technology innovation board Journal reporter learned exclusively that,Volcano Engine Edge Cloud and Runxin Technology jointly create AI voice toys, and its Wi-Fi module adopts Hengxuan Technology. Graffiti Intelligence also participates in providing related modules and docking platforms..

From the live experience, consumers can interact with the AI toy "puppy" in voice, so that they can answer questions and provide companionship.

Some people in the industrial chain expressed optimism about the follow-up sales of AI voice toys. He told the science and technology innovation board Journal reporter,It is expected that the first batch of AI toys will be listed at the end of this year and early next year. It is expected that a large number of players will join the competition in the industry in the first half of next year.However, the landing of AI toys also has certain challenges. "First of all, AI toys need to be based on high-quality knowledge bases of different age groups in order to achieve better human-computer interaction. Besides,The daily interaction frequency of AI toys is high. For users, the cost of cloud reasoning will be a big expense, and it is also a difficulty that affects its landing.. "

At the meeting,Volcano Engine Video Cloud, Lexin Technology and ToyCity jointly launched the AI+ Hardware Smart Jump Program., combined with the big model of bean curd, Volcano Engine’s anthropomorphic voice dialogue technology, ToyCity tide play design, as well as the AI chip of Lexin Technology and other product strengths, to promote the popularization of AI tide play. It is reported that Lexin Technology will provide a one-stop hardware solution for AI Chaowan, including end-side audio and video processing.

In terms of robots,Horizon’s sweet potato robot and Volcano Engine Edge Cloud are developing intelligent robots based on large model gateways.A robot intelligent perception and control system scheme based on edge large model gateway is built.

Facing the robot call scenario, the big model gateway can make use of the edge to call the big model service nearby based on the originating position of the end-side request, and improve the response speed and ensure the call stability through the product capability of the edge big model gateway, so as to realize the near access and query acceleration of the big model for robot equipment and call it on demand at a lower price and faster speed.

In addition, Leju Robot also cooperates with the bean bag model. At present, Leju robot is mainly used in scientific research, exhibition hall tour, etc., and is also exploring the application in the industrial field.

In terms of end-side AI, the bean bag model has been connected to many smart terminals such as mobile phones and PCs, covering about 300 million terminal devices, and the call volume of the bean bag model from smart terminals has increased by 100 times in half a year.

It is reported that HONOR’s magic retouching and AI abstract functions are provided by the bean bag model, and vivo mobile phone adopts the bean bag music model, which provides music creation ability for photo album users. Bean bag music model will create AI lyrics and songs according to the materials provided by users, and generate personalized movies for users.

Tan Dai told science and technology innovation board Daily that most Android phones in China are cooperating with Doubao. “For mobile phone manufacturers, bean bags will be used in some scenes, other large models will be used in some scenes, or a certain scene will be mixed.. For enterprise users, a cloudy or multi-model strategy is definitely needed, which I think is normal. In the end, the ability is better and the cost is lower. Who will be used? This account is easy to calculate. "

The reporter of science and technology innovation board Daily found on the spot that a large number of application scenarios have been explored based on ByteDance’s AI agent development platform button.

For example, cooperate with Supor to explore the generation of AI personalized recipes and improve the service level of cooking machines.

AI fish farming in cooperation with Ji Zhiyun, the agent automatically provides users with an optimization scheme according to the real-time data of fish tank equipment. For example, when the water quality is not up to standard, the agent can automatically adjust the operation mode of the pump to improve the growth environment of fish or plants.

It is reported that there are more than 1 million active developers in the agent development community of Button, and more than 2 million agent applications have been created.

In terms of car companies, Dongfeng Motor, Zhiji Automobile, and Mercedes-Benz’s SMART Car have cooperated with the bean bag model in smart cockpits and other aspects. Tan Dai said that more than 80% of domestic mainstream automobile brands are cooperating with the big model of bean bag.

ByteDance is expected to launch version 1.5 of the video generation model of bean curd with longer video generation capability in the spring of 2025. Talking about the possible computational challenges, Tan Dai said, "The Volcano Ark provides MaaS reasoning service for the large model of bean curd, which I think is sufficient from our own reserves. It is for this reason that we can now provide the industry’s largest TPM and RPM. When the user is stuck or blocked, this is not necessarily the reason for insufficient computing power. After all, you are using an application and a system. Even if there is something wrong with the user’s authentication, it will affect the fluency of the whole system, including whether there is engineering optimization. This is actually not just a simple calculation problem. "

For the market competition in the future big model field, Tan Dai said that it is still in the early stage of the market. "To be honest, from my point of view, I don’t care much about competition now, because this market is still very early, and maybe one thousandth of this market has just been developed. At this time, you don’t really have to care about competition. What you care about is what users’ needs are not met. "

Vermicelli is a kind of traditional food deeply loved by Chinese people, and it has a long history of processing. There have been records about making vermicelli in ancient books such as Qi Min Yao Shu and Compendium of Materia Medica. Vermicelli is a strip-shaped, filamentary or ribbon-shaped product mainly made of starch such as potatoes and beans through the processes of mixing, molding, cooling and drying. According to the standard GB/T23587-2009, vermicelli is called "vermicelli" if the product diameter is more than ≤1 mm, and vermicelli is called "vermicelli" if the diameter is less than or equal to 1 mm. Generally speaking, vermicelli is better than vermicelli.

Vermicelli is rich in raw materials, simple in production and operation, diverse in product forms, deeply loved by consumers, with broad market prospects and rapid development of the industry. Vermicelli products can be eaten in a variety of ways, such as mixing, frying, steaming, stewing and cooking. At present, vermicelli products have become one of the essential foods on the table of Chinese consumers, and many vermicelli products have been widely exported to Japan, South Korea, the United States and Europe and other countries and regions.

However, with the development of social economy and the improvement of people’s living standards in China, consumers’ demand for high-quality, nutritious, convenient and diversified foods is increasing day by day, as well as economic restrictions, the problems affecting the healthy development of vermicelli industry in China are becoming increasingly prominent, and counterfeiting incidents occur frequently, which has attracted the attention of our government and relevant departments.

What do you know about "poison vermicelli"?

Where did the vermicelli come from?

The picture comes from the Internet.

At the 315 party in 2022, CCTV exposed the "fake sweet potato vermicelli in Yuzhou" because cassava starch was used as the inferior sweet potato starch. The ingredients of an "iron stick yam vermicelli" produced in Yuzhou City, Henan Province read: whole juice of iron stick yam, sweet potato starch and drinking water, but the actual yam composition is only about 20%, and the main raw material is unlabeled cassava powder. Some responsible persons said that using cassava starch instead of sweet potato starch was a hidden rule in the industry for 10 years. "All of them are made of cassava, with a good conscience and more sweet potato powder."

What are the hazards of "poison vermicelli"

The picture comes from the Internet.

Sweet potato starch contains carotene and vitamin C, and it is also found that sweet potato contains anticancer substances with high nutritional value. Two kilograms of sweet potato starch can produce about one kilogram of vermicelli. The price of one kilogram of sweet potato starch is between 3.5 yuan and 4 yuan, while the market price of one kilogram of pure sweet potato vermicelli is about 8 yuan. The profit of producing sweet potato vermicelli with pure sweet potato starch is very thin, but the price of one kilogram of cassava starch is only 1.8 yuan, and the purpose of shoddy is to maximize profits. From the appearance, both kinds of starch are white and delicate, and it is difficult to distinguish the vermicelli if it is not compared in detail, so merchants use these characteristics to "confuse the fake with the real".

The picture comes from the Internet.

In addition to the price, consumers will be detrimental to the interests. The most daunting thing is that cassava starch is toxic when eaten raw. The roots, stems, leaves and skins of cassava all contain a toxic substance called "cyanosides". Fresh cassava is the most toxic, and eating 150g raw may lead to poisoning. In 2019, there were incidents of "eating cassava poisoning" in Yunnan and Guangxi. However, this kind of "cyanoside" will disappear at a high temperature above 70℃, so cassava starch needs to be heated before it can be eaten, while ordinary starch has no natural toxin and can be eaten directly. This kind of "fake sweet potato starch", once a large number of raw vermicelli are eaten by mistake, or cassava is not peeled when it is made into starch, the consequences are unimaginable and there are great security risks. Long-term consumption of this food containing "cyanosides" will also pose a serious threat to health.

How to distinguish "poison vermicelli"?

Look at the color

The picture comes from the Internet.

The color of sweet potato vermicelli is yellow and dark; Cassava vermicelli is white, transparent and smooth to the touch.

However, many manufacturers of vermicelli intentionally add food pigment instead of the color of sweet potato vermicelli in order to save costs and earn high profits to the maximum extent. In this case, we must use the second method to assist in identification-smell.

Smell

After the pure sweet potato vermicelli is soaked in hot water, the water in the bowl is still clear, the vermicelli does not fade, and the faint sweet potato flavor can be smelled; After cassava vermicelli was soaked in hot water, the water became turbid, and the vermicelli was crystal clear, but it smelled without any smell.

Toughness and bending degree

The picture comes from the Internet.

In the dry state, sweet potato vermicelli is very brittle and brittle, and it will break when it is folded. Therefore, there will be a lot of crumbs on the shelf where sweet potato vermicelli is placed, and it is easy to soften when cooked in a pot. On the other hand, if the vermicelli is very tough and needs scissors to cut it off, it means that the vermicelli is not pure sweet potato vermicelli because various ingredients such as gelatin and cassava powder were added in the production process.

Burn with fire

Sweet potato starch is made of sweet potato with high starch content, and its tissue shape is composed of tiny particles, which is not strong in water absorption and has the characteristics of crystallinity. After being lit with a lighter, it will emit black smoke, but it will not produce a pungent smell. After burning, it will produce black powder, which will become fine powder with a gentle pinch. However, if the noodles made of cassava powder are ignited with a lighter, they will not burn fully. If you pinch the powder by hand, you will find that the hardness of the powder is stronger, and even there will be tiny particles that cannot be pinched.

Tips

When buying sweet potato vermicelli, don’t be greedy for cheap, get what you want for a price, be vigilant about this matter and let your family and yourself have peace of mind.
