After the listing of Xiaomi SU7, Xiaomi Automobile Factory began to enter a busy production rhythm.

A few days ago, the reporter of national business daily walked into the Xiaomi Automobile Production Park in Beijing Economic Development Zone, and the rows of millet SU7 parked neatly in the square were visible.

"This is just a part of the new car to be delivered, and there are still many parked in the factory." On April 2nd, a staff member of Xiaomi Automobile Factory said in an interview with national business daily that every day, a new SU7 car was transported to all parts of the country by a sedan chair to prepare for the official delivery on April 3rd.

On the morning of April 3, the first delivery ceremony of Xiaomi SU7 was held in the assembly workshop of Xiaomi Automobile Factory, and the first delivery was started simultaneously in the delivery centers of 28 cities nationwide. "Starting today, Xiaomi officially became a car factory. Should everyone call me Director Lei? " On the same day, Lei Jun, chairman of Xiaomi Group, wrote in his personal Weibo that.

According to official data, Xiaomi SU7 has been on sale for five days, with 100,000 users (5,000 yuan) and more than 40,000 orders locked. "Now, the delivery cycle of Xiaomi SU7 standard and Pro models is about 20 weeks, but the delivery cycle of Max high-end models is expected to be two weeks longer than the other two versions." The sales staff of Xiaomi Auto Super Factory Store told reporters.

A supplier who visited Xiaomi Automobile Factory on the same day told reporters that his company recently received an email from Xiaomi Automobile requesting to increase the production capacity of accessories. "Xiaomi Automobile has raised the original planned monthly production of about 7,000 vehicles to about 12,000 vehicles." However, the above-mentioned Xiaomi automobile suppliers admit that although all suppliers can supply the accessories needed by Xiaomi automobile, its own production capacity is still difficult to achieve (this goal) in a short time.

The delivery of new cars can take up to 8 months, and the annual production capacity demand has increased to 120,000 units?

"I am particularly worried that when it comes to fire, everyone will not buy it. What is even more worrying is that if everyone comes to buy it, it will take a year or two, and it will definitely be miserable. " Before the listing of Xiaomi SU7, Lei Jun expressed his concern about the delivery rhythm of new cars when interviewed by CCTV news.

When the reporter actually visited an offline store of Xiaomi Automobile in Beijing, he found that at present, the store is "crowded" and the sales in the store are overwhelmed. Correspondingly, the order volume of Xiaomi Automobile keeps rising. According to the information released by Xiaomi, the order volume of Xiaomi SU7 broke 10,000 vehicles in 4 minutes, 20,000 vehicles in 7 minutes, 50,000 vehicles in 27 minutes and 88,898 vehicles in 24 hours.

On April 3, the reporter checked Xiaomi Auto APP and found that the delivery cycle of Xiaomi SU7 standard version after locking the order is expected to be 21 weeks to 24 weeks (5 to 6 months); The delivery cycle of Pro version is expected to be 20~23 weeks after locking the order; The delivery cycle after the Max version is locked is 29~32 weeks (7.5~8 months).

According to the plan, Xiaomi SU7 Standard Edition and Max Edition are expected to start delivery from the end of April, and Pro Edition is expected to start delivery from the end of May. "(We) are making every effort to increase production capacity and speed up delivery." Xiaomi Automobile said.

When the reporter visited, he found that at present, Xiaomi Automobile Factory is still advancing according to the single-shift production system and has not worked overtime. "After communicating with the person in charge of Xiaomi Automobile Factory, I learned that the existing daily production capacity of Xiaomi Automobile Factory is less than 300." The above-mentioned Xiaomi automobile supplier revealed to reporters.

A worker of Xiaomi Automobile Factory told reporters that Xiaomi Automobile Factory is expected to produce about 240 cars every day. "The factory is still in normal production scheduling, and there is no special requirement. We generally don’t work overtime." The above-mentioned Xiaomi automobile factory workers said.

The above-mentioned Xiaomi automobile supplier also said that a few days ago, Xiaomi automobile issued a demand to suppliers to increase production capacity. He went to Xiaomi automobile factory this time to do production capacity evaluation. "After understanding, I found that even if our suppliers can provide accessories, it is difficult for Xiaomi Automobile Factory to achieve rapid increase in production capacity in a short time." The above Xiaomi automobile supplier said.

According to several suppliers of Xiaomi Automobile, Xiaomi Automobile has increased its annual production capacity demand to 120,000 units in 2024. In this regard, the reporter verified the Xiaomi Group, but as of press time, no response was received.

Borrow qualification+build your own factory?

According to the plan, Xiaomi Automobile plans to build a vehicle manufacturing plant in Beijing Economic Development Zone in two phases, of which the first phase covers an area of about 720,000 square meters and has an annual production capacity of 150,000 vehicles, which will be completed in June 2023; The second phase is scheduled to start in 2024 and be completed in 2025.

"The factory has built six core workshops-stamping workshop, body workshop, painting workshop, assembly workshop, die casting workshop and battery workshop. In the case of full production, Xiaomi Automobile Factory has a millet SU7 off the assembly line every 76 seconds. " Lei Jun said.

During the visit, the reporter found that the second phase construction of Fangxindian Village and Xiaozhang wan Village in Yizhuang New Town has not been officially launched. At present, some areas have been demolished, but the work of vacating Fangxindian Village has not been officially started.

"Now the house in the village can still be rented out, but I don’t know when I can live, maybe one month or two months. There is no specific time to vacate." A number of residents entering and leaving the village told reporters.

It is worth noting that it is reported that the production qualification and factory of Xiaomi Automobile do not belong to Xiaomi Automobile. In this regard, the reporter verified the Xiaomi Group, and the other party only replied: "At present, these issues are not convenient to disclose, and the official disclosure information will prevail."

According to public information, if you want to build a car, car companies must not only obtain the qualification of a new pure electric passenger car production project approved by the National Development and Reform Commission, but also obtain the qualification of a new vehicle production enterprise approved by the Ministry of Industry and Information Technology, that is, "double qualification".

Last November, Reuters reported that in August, 2023, Xiaomi Automobile had been approved by the National Development and Reform Commission to produce electric vehicles. However, the news was not officially confirmed by Xiaomi Group.

On November 15th last year, Xiaomi brand pure electric car appeared in the 377th batch of Announcement of Road Motor Vehicle Manufacturers and Products issued by the Ministry of Industry and Information Technology. According to the information of the Ministry of Industry and Information Technology, the reporting enterprise of Xiaomi Automobile this time is Beijing Automobile Group Off-road Vehicle Co., Ltd. (hereinafter referred to as Beijing Off-road), and the tail label of the product also has the words "Beijing Xiaomi". However, the application materials show that the production address is "No.21 Courtyard, Huanjing Road, Beijing Economic and Technological Development Zone", which is the current address of Xiaomi Automobile Production Base.

Yang Weibin, an expert on new energy vehicles and power batteries, said in an interview that from the information released by the Ministry of Industry and Information Technology, Xiaomi Automobile either adopted the cooperation mode of Jianghuai and Weilai, first borrowed the qualification, and then applied for independent qualification after reaching a certain amount (referring to the scale). However, Xiaomi has not confirmed this news.

On June 29th, "Aspartame causes cancer"

This topic topped the hot search list.

Arouse a heated discussion among netizens.

It is reported that the International Agency for Research on Cancer, a subsidiary of the World Health Organization, held an expert meeting in early June to evaluate whether some products are potentially dangerous based on all published evidence. At the meeting, it was determined that aspartame "may be carcinogenic to human body". At the same time, the Joint FAO/WHO Expert Committee on Food Additives (JECFA) is also reviewing the use of aspartame and will announce the results in July.

WHO responded to the media that it will publish relevant content on this topic on July 14th, but did not disclose the specific content.

According to the Washington Post on the 22nd, aspartame is one of the most common artificial sweeteners in the world. Last year, a study in France showed that eating a large amount of aspartame may increase the risk of cancer in adults, and the United States began to re-examine this sweetener. The American Beverage Association, as the representative of beverage manufacturers, and related industry organizations refute this conclusion. Officials from the American Beverage Association said that aspartame is generally considered safe by the scientific and regulatory circles, which is the conclusion reached by food safety agencies around the world again and again.

Aspartame is the most common synthetic sweetener, such as sugar-free cola and Sprite, which is used to replace sucrose. At present, many foods and beverages labeled as "sugar-free" on the market, such as Coca-Cola diet soda, Mars Extra chewing gum and some Snapple drinks, actually use sweeteners such as aspartame.

Many netizens began to feel nervous:

Reviews from netizens

@Icomtys: Put down my diet coke immediately.

@Hellen wants to teach and educate people: What else can you eat? What to drink?

What’s delicious about coriander? Fortunately, I don’t like sweetness.

@ 京京: I will never eat anything but sugary cola.

@ Tiger Mom Return: My family has diabetes, and there has always been a saying that I should not eat aspartame.

The food and beverage circle began to express its position.

Have a brand emergency response

Aspartame will be listed as a "possible carcinogen". As soon as the news came out, associations and companies in the food and beverage circle stood up and expressed their views.

Kate Loatman, executive director of the International Beverage Association (ICBA), said that IARC’s statement is contrary to a large number of high-quality scientific research conclusions for a long time, or it may mislead consumers to give up safe sugar-free and low-sugar choices and consume more sugar instead. "We still believe in the safety of aspartame because we have conducted safety assessments with food safety authorities from more than 90 countries." Kate Loatman said.

The response of the International Beverage Association also stated that, contrary to the conclusion of IARC, a review report issued by WHO, the parent organization of IARC, in April 2022 showed that there was "no obvious correlation" between high consumption of low-calorie or calorie-free sweeteners and cancer mortality, and it would not cause any form of cancer.

Frances Hunt-Wood, secretary-general of the International Sweetener Association (ISA), accused "IARC is not a food safety agency" and believed that the agency’s evaluation of aspartame "is not comprehensive in science, because it is based on many widely questioned studies and may mislead consumers." Many members of this association include Mars Wrigley and Coca-Cola, both of which have introduced products containing aspartame.

In addition, some China brands immediately distanced themselves from aspartame.

The person in charge of Naixue’s tea said that in November last year, all products had been upgraded with the natural sugar substitute "Luohan"; Siraitia grosvenorii is a medicinal and edible plant, and its extract "Siraitia grosvenorii sugar" is a natural sweet fructose substance.

On the other hand, Yuanqi Forest said that the company’s entire line of products also does not contain aspartame. "Yuanqi Forest ingredients list is cleaner, and Yuanqi Forest Coke has 0 sugar, 0 fat, 0 card and 0 aspartame."

Sugar-free drinks are healthier?

The harm of sweeteners may be underestimated by us.

Aspartame is one of the most commonly used sweeteners. We use aspartame in familiar sugar-free drinks such as "Coke Zero".

Many people know the harm of excessive sugar intake, which will increase the risk of obesity, type 2 diabetes, cardiovascular disease, and even cancer. The emergence of artificial sweeteners and sugar substitutes seems to help people avoid the harm caused by excessive sugar intake, and at the same time satisfy the taste. But is this really the case?

In 2021, it was reported by the media that Mr. Kong (pseudonym), 30, likes to drink carbonated drinks, but he is worried that drinking too many sugary drinks will lead to obesity and diabetes. He fills the refrigerator with "sugar-free" or "zero sugar" drinks and drinks at least 4 or 5 bottles every day. Later, Mr. Kong always felt thirsty and his urine output increased, so he went to the hospital. After the doctor knew the course and history of the disease in detail, combined with typical symptoms such as polydipsia and polyuria, and improved the examination in time, Mr. Kong was diagnosed as the first onset-diabetes complicated with ketoacidosis.

Tan Jinmei, a physician of nephrology endocrinology at Wuhan Yangtze River Shipping General Hospital and Wuhan Brain Hospital, explained that sugar-free does not mean that there is no sugar, but it does not contain sucrose, glucose and other sugar-increasing components, and various forms of artificial sweeteners are used instead. Once the sweetener is consumed too much, it will not only stimulate the production of insulin, affect the sensitivity of insulin receptors, but also increase appetite reflexively, leading to excessive calories. Therefore, Mr. Kong’s long-term drinking of sugar-free drinks instead of normal drinking water has accelerated the metabolism of the body out of control and caused diabetes.

Studies have shown that the sweetness of sweeteners can make people feel that they have eaten sugary food, which in turn stimulates the human body to produce insulin, leading to a drop in blood sugar, which makes people feel hungry and increase their appetite. Although the "sweetener" in sugar-free drinks has zero calories, long-term intake of artificial sugar substitutes will lead to insulin endocrine imbalance, which will lead to human metabolism disorder.

On September 7, 2022, researchers from the World Health Organization, the French National Center for Health and Medical Research and the University of Paris published a research paper in the top medical journal BMJ. This study shows that artificial sweeteners are not a healthy and safe substitute for sugar, and higher intake of artificial sweeteners increases the risk of heart disease and stroke.

The Chinese nation has a civilization history of thousands of years, and has created splendid ancient culture, especially China’s ancient science and technology, such as papermaking, printing, gunpowder and compass, which have made great contributions to the progress of world civilization. Needham, a famous British scholar, pointed out after studying the history of world science and technology that before the middle of the Ming Dynasty, China’s inventions and discoveries far surpassed those of Europe at the same time; China’s ancient science and technology have been ahead of the rest of the world for a long time: China’s Zhouyi Suan Jing, written in the Qin and Han Dynasties, put forward a special case of Pythagorean theorem 500 years earlier than the West; Zhang Heng of the Eastern Han Dynasty invented the armillary sphere and the seismograph, more than 1,700 years earlier than Europe. Zu Chongzhi in the Southern Dynasties accurately calculated that pi was between 3.1415926 and 3.1415927, which was more than a thousand years earlier than that in Europe …

In order for today’s readers to inherit and carry forward the excellent traditions of the Chinese nation-being brave in exploration, good at innovation and good at discovery and invention, our society began to mobilize, plan, organize and publish this series of books as early as the 1980s. At that time, Mr. Hu Daojing (1913-2003), an old publisher and scholar of history of science, was invited as the editor-in-chief of the series. Under the guidance of Hu Lao, the work of selecting books and soliciting contributions was carried out.

The series has been supported by many outstanding scholars and written in succession. After publication, it has also been welcomed by readers and achieved good social benefits. However, due to various reasons, only five kinds of books were published in the 20th century (Annotation of Kao Gong Ji, Annotation of Dietetic Materia Medica, Annotation of Wang’s Agricultural Books in Donglu, Annotation of Tiangong Kaiwu, Annotation of Compiling and Compiling the Things in Kangxi’s Leisure Time), so they had to be suspended. After Hu Lao’s death, the publishing of series is even more difficult.

In the 21st century, our society decided to restart the publication of series. With the support of Shandong University, on the basis of the original, the bibliography was re-selected, the compilation style was revised, and the author was invited again to continue to complete the project perfectly.

The restart of the series has won the support of many old authors, especially Mr. Pan Jixing, a famous expert in the history of science and technology. He not only put forward suggestions such as revising the style, providing topics and recommending authors, but also generously promised to undertake the review of the English titles of this series. In addition, the series also invited many outstanding scholars, such as Guo Shuchun, a historian of mathematics, Liu Aiyun, a Chinese medicine expert, Zheng Jinsheng, an expert in the study of Chinese medicine history and literature, Miao Qiyu and Ma Zongshen, an agronomist, Gao Suijie, a forensic scientist, Cheng Zhenyi, Wen Renjun, Lu Jingyan, Zhang Binglun and Li Di, to write in succession.

For ordinary readers, it is not easy to read China’s ancient scientific and technological classics. After 40 years of readers’ examination and several times of perfection by the author, this series of books has finally determined the style of "original text+annotation+translation", which integrates classic original text, detailed annotation and popular translation, which not only facilitates readers to easily learn China’s ancient science and technology, but also meets the needs of some readers to read the original text. It can be said that it is a necessary introductory reading for China ancient science and technology lovers.

Up to now, the series has published 17 varieties, as follows:

Annotation of Kao Gong Ji (Revised Edition)

Read the original text

　　The Spring Festival of 2019, which just passed, is destined to make Chen Can and Jason unforgettable. Together with dozens of other Internet addiction teenagers, they spent the New Year in an Internet addiction treatment center in Beijing. China Youth Psychological Growth Base, located in the southern suburbs of Beijing, was founded in 2003, and it is the first institution in China that specializes in treating teenagers and youths with Internet addiction. Every child and young person who walks in here has a different history of internet addiction, but because of their internet addiction, they have brought similar pain and suffering to their respective families. In the past 16 years, the number of Internet addiction rehabilitation institutions such as China Youth Psychological Growth Base has increased from one to two or three hundred in China, which is a worrying phenomenon, because there are more and more Internet addiction teenagers, and the unfortunate families behind them are also increasing day by day.

　　The fall of a schoolmaster took only one semester.

　　At present, many children with Chen Can are enjoying their first winter vacation after entering the university. A few years ago, Chen Can’s mother imagined such a future for Chen Can, and believed that Chen Can must be a famous university. Chen Can’s mother recalled that Chen Can had excellent academic performance in junior high school. At that time, his goal was to be admitted to the best local high school with the first place in the county. However, everything changed after Chen Can fell in love with online games.

　　Chen Can, who is in front of the reporter of China Youth Daily and Zhongqing Online, is a polite and eloquent young man. He has entered the final stage of Internet addiction treatment in the psychological growth base of young people in China, and will soon resume his normal study and life. He regretted his experience of indulging in online games in the past few years.

　　Chen Can recalled that he was addicted to an online game in junior high school. He played for three or four hours after school every night, and rarely fell asleep before 12 o’clock at night. However, due to my solid academic foundation and high learning efficiency in class during the day, my academic performance has not been greatly affected.

　　In the senior high school entrance examination, Chen Can’s score was among the top ten in the county. Although there is a certain gap from the goal of getting the first place in the county, it is enough to ensure that he can successfully enter the best local high school.

　　After entering high school, Chen Can continued the habit of staying up late to play games every night, but his high school studies were obviously aggravated, and it was already difficult for him to take both games and studies into consideration. In junior high school, Chen Can can still take a nap if he is too sleepy in class during the day, which basically won’t have much impact on his study, but it is impossible in senior high school. Due to lack of energy during the day, there is no guarantee to listen carefully in class. In just one semester, Chen Can’s academic performance has dropped sharply. After a day’s suspension due to a conflict with the teacher, Chen Can found that the suspension would give him more time and reason to play games, and then he began to deliberately skip class, and his learning progress could not keep up. Later, Chen Can directly applied for suspension.

　　To Chen Can’s mother’s distress, as a parent, there is nothing she can do in the face of her son’s addiction to games and the resulting "fall" in life.

　　Chen Can’s mother recalled that in fact, as early as junior high school in Chen Can, she and Chen Can’s father had been urging Chen Can not to play games for so long, but the dissuasion had little effect. Later, it was even easy to cause Chen Can’s emotional catharsis. Chen Can’s mother remembers that once there was a guest at home, Chen Can kicked over the gift sent by the guest in order to express his dissatisfaction, which was very rude. As for losing your temper with your parents, it is even more common. At first, Chen Can’s mother thought that the child was rebellious in adolescence. After this period of time, the child would get better. Until Chen Can’s academic performance in high school plummeted and quickly changed from a "schoolmaster" to a stubborn poor student, Chen Can’s parents thought that the child was so addicted to games that it was necessary to be treated.

　　Chen Can’s mother first found a friend who is a psychiatrist. After a preliminary diagnosis, this friend found that Chen Can’s Internet addiction was very serious, and suggested taking measures to quit it as soon as possible.

　　When I heard the doctor’s diagnosis of her son, Chen Can’s mother was desperate for the first time in her life. The child who once made herself and the whole family extremely proud actually fell to the point where serious mental problems appeared because she was addicted to online games.

　　Now Chen Can has realized that at the height of Internet addiction, he was not only obsessed with online games, but also evaded and rejected real life. He would rather chat with people online than talk to them in reality.

　　In April, 2017, Chen Can came to China Youth Psychological Growth Base for the first time under the leadership of her parents, but in order to get back to school before school starts in September, the treatment lasted only five months. As a result, because of incomplete treatment, Chen Can relapsed after returning to school for one month.

　　In December 2017, Chen Can once again came to the China Youth Psychological Growth Base. After a winter vacation, he thought he was good, but when he got home, he quickly returned to the state of being addicted to online games.

　　In May 2018, Chen Can’s parents took Chen Can to the China Youth Psychological Growth Base for the third time. This time, the treatment has been as long as nine months now. The doctor’s advice is that the treatment will not be over until Chen Can is completely cured of Internet addiction.

　　As the treatment has entered the final stage, it is expected that Chen Can will be able to really return to normal life when the new semester begins. But precious youth has been delayed for three years. Chen Can’s former senior one classmates have entered university life at this time, while Chen Can’s mother has already given up her dream of a famous university for her son.

　　Chen Can felt that he was unlikely to go back to high school again. He planned to study high school courses by himself while working, and then he planned to enter the university. Chen Can’s mother no longer expects her son to be admitted to the university. Her only expectation is that Chen Can can lead a normal life safely.

　　A former e-sports player who lost himself.

　　Jason, 26, has been addicted to Internet for almost 10 years.

　　Jason’s father told the reporter of China Youth Daily and Zhongqing Online that Jason had been addicted to online games since his sophomore year. At that time, he went to Internet cafes every day, and his studies were a mess. There was nothing the school could do about how to save the child, so it suggested that Jason’s father transfer him to a local militarized school.

　　In the new school, Jason’s mobile phone was confiscated, and he usually lived in the school. He was forbidden to leave the school at will. He didn’t have access to online games at all. In this way, Jason’s academic performance gradually picked up, but Internet addiction also tortured him mentally. In the first half year of his new school, Jason’s father lied about his child’s illness three times to meet his son’s internet addiction demand, helped Jason to ask for leave, took him out of school and took him home to play online games. However, since then, Jason’s Internet addiction has been temporarily suppressed under the strict control of the school.

　　After studying in a new school for two years, Jason was finally admitted to a good local university. After going to college, Jason’s playing games was no longer out of control. Jason told the reporter of China Youth Daily and Zhongqing Online that his studies in college were not affected by playing games. However, Jason’s father said that his son spent almost every day in the Internet cafe since his sophomore year, and finally he graduated from college, just muddling through.

　　Jason also participated in the national college students’ e-sports competition and won an award when he was in college, but it was this experience that made him understand that an e-sports player is far from playing games, and needs strict and boring training. When entertainment turns into work, few people can actually persist.

　　Therefore, when talking about quitting his job one year after graduating from college and starting to focus on online games completely, Jason’s answer to the reporter’s question of why he didn’t take part in e-sports competition again was that he could never aim at becoming an e-sports player, because it was too difficult to take that road.

　　In the summer of 2016, I graduated from Jason University, and then entered a local company with good conditions in all aspects step by step. However, work can’t bring people a sense of excitement and accomplishment as quickly as games. After gradually discovering the dullness of work, Jason began to devote more energy to online games, from going to Internet cafes to play games after work at the beginning, to taking time off to play games, and then to absenteeism to play games. The unit leader talked to him again and again, and talked to his parents, but they couldn’t make him change his mind.

　　Less than a year after graduating from college, Jason voluntarily gave up his first job in life, and then looked for several jobs, but all of them could not be maintained within a few days. Jason’s father knows very well that his son’s mind is completely on online games. Where can real life bring him excitement and excitement like the online world?

　　In the following year, Jason lived a black-and-white life. Jason’s father was annoyed but helplessly watched his son spend every night in the Internet cafe. He went home to eat and sleep early in the morning, slept until three or four o’clock in the afternoon, and then ate something to go to the Internet cafe. Later, Jason stopped going to Internet cafes, so he shut himself in his room all day. He said that he didn’t always play games, and he spent a lot of time browsing and chatting with people online, but he just couldn’t leave the computer.

　　Jason’s father found that his son, who was cheerful and talkative, had become listless and could not even speak fluently after blocking himself in the online world for nearly a year.

　　Jason’s father felt that his son was "dying" mentally, and he had to find a way to save his son.

　　In May, 2018, Jason’s father made up an excuse to cheat Jason to Beijing and live directly in the psychological growth base for teenagers in China. Jason found that he came here to give himself up Internet addiction, and then he rebelled by means of hunger strike, leading other children to "riot" and running away. Jason’s father was determined not to compromise with his son.

　　After various means of resistance failed, Jason finally understood his father’s determination and began to receive treatment.

　　The treatment process is full of challenges. After the son started Morita therapy (the treated person is alone in a room with only one bed in the room, which ensures the basic living conditions of the treated person, but there are no social activities, reading, entertainment and other activities to force the treated person to think, examine and recognize himself), Jason’s father did not expect that other children only need Morita therapy for 30 to 40 days, but his son actually did it for 70 days.

　　The harm of Internet addiction to teenagers will become increasingly prominent.

　　In the past 16 years, China Youth Psychological Growth Base has treated more than 10,000 teenagers with Internet addiction. Tao Ran, director of China Youth Psychological Growth Base and director of Addiction Medicine Center of Beijing Military Region General Hospital, told China Youth Daily and Zhongqing Online reporter, "A large number of examples show that even if teenagers with Internet addiction complete the treatment of quitting Internet addiction, the physical and mental harm that Internet addiction brings to children will be lifelong."

　　First of all, Internet addiction does great harm to children’s health.

　　When Tao Ran treated the children, he found that 90% of teenagers with Internet addiction were lean and thin, and their weight was not up to standard. During the treatment in the base, these children are also generally weak and sick. If the weather changes slightly, they will easily catch a cold and have a fever. Gastrointestinal function is also worse than that of healthy children.

　　The problem of vision decline of teenagers with internet addiction is also very prominent. According to the recommended standards of international medicine, teenagers over 8 years old should play video games for less than one hour every day, but teenagers with internet addiction generally play video games for more than three or four hours every day, which can easily cause serious damage to their vision.

　　Internet addiction teenagers have been sitting quietly for a long time facing computers and mobile phones, and lack of sports. Tao Ran said sadly that these children were supposed to be the most energetic, sunny and energetic, but because they were addicted to games, they delayed the best opportunity for physical development.

　　Secondly, the permanent damage caused by internet addiction to children’s brains directly affects children’s intellectual development, mental state and social life ability.

　　According to Tao Ran, related research shows that long-term addiction to video games will lead to frontal lobe ischemia of teenagers’ brains and affect their development. In addition to affecting children’s intellectual development, the most important thing is the harm caused to children’s psychological development.

　　Tao Ran said that there is now a metaphor for Internet addiction teenagers as "machine brain". This means that teenagers with internet addiction generally have no normal emotions and feelings, and like a robot, they treat people and things around them with a cold attitude. They only have emotions when they are addicted to games, but in real life, they are not interested in everything.

　　However, human beings are gregarious animals, and the development of human society is based on gregarious and social interaction. Only normal communication between people can achieve healthy psychological development. If a teenager or a minor faces a computer or a mobile phone every day and looks for life in the game, his world outlook, values and outlook on life are not mature, and his brain is still in the developing stage. In this state of life, these internet addiction teenagers often have no human feelings, do not understand interpersonal relationships, leave school, and then leave society when they are older. Their life has become virtual, that is, to face life in the way of games, and then to moralize and legalize.

　　In Tao Ran’s view, the mental development of teenagers with Internet addiction has been seriously affected because they have been addicted to online games for a long time, and their mental age is often 4 to 5 years younger than their actual age. The immature psychology of teenagers with internet addiction, coupled with the misleading that either you hit me or I hit you and kill people in the game world, leads them to tend to solve problems by violence.

　　According to Tao Ran’s investigation, about 86% teenagers with Internet addiction have used violence against their relatives.

　　When parents and family members stop themselves from playing games, teenagers with internet addiction often beat and scold their parents and family members instead of admitting their mistakes. What’s more, if their requirements for playing games are not met, teenagers with Internet addiction may even kill their parents. On December 31 last year, such a tragedy happened in Hengnan County, Hengyang City, Hunan Province. A 13-year-old junior high school student killed his parents with a hammer because he couldn’t ask his parents for the internet fee. Such vicious cases related to Internet addiction have been common in the past few years.

　　The China Youth Psychological Growth Base located in Beijing has not received many teenagers with Internet addiction from Beijing, accounting for only about 5%. This is another typical phenomenon that Internet addiction harms Chinese teenagers, that is, the bigger the city, the less serious the problem is, the situation in small and medium-sized cities is worse than that in big cities, and the problem of teenagers with Internet addiction in rural areas is the most serious.

　　Tao Ran said that mainly because of the families in big cities, children get more perfect family education, and parents’ educational concepts are more scientific, so they will avoid and interfere with children’s excessive contact with video games as soon as possible. In addition, children in big cities have too many things to play and learn, and they don’t have so much time and space to indulge in online games.

　　In contrast, children in rural areas are obviously lacking in family education, and some rural children may also be left behind. Grandparents are responsible for taking care of their children, and often have no more energy to restrain their children from surfing the Internet and playing mobile phones.

　　Don’t think that the problem of internet addiction teenagers in rural areas is far away from those of us who live in big cities. Tao Ran said anxiously that in the future, after these left-behind children and internet addiction teenagers in rural areas enter the city, their psychological and personality problems caused by online games for a long time really need the attention of the whole society. "You can’t imagine who these internet addiction teenagers may hurt after what they encounter."

　　Behind the name recognition of e-sports is the growing problem of teenagers’ internet addiction.

　　On November 3, 2018, the League of Legends S8 season global finals, the IG team from China won the championship. For a time, domestic media rushed to report, including some mainstream media that had previously reserved their position on e-sports. Looking at the past two years, the exposure rate of e-sports in the media is getting higher and higher, from the analysis of professional industrialization of e-sports, to the reports that China players have repeatedly won good results in world competitions, and then to the discussion of e-sports entering the Asian Games and the Olympic Games. However, compared with the stricter control of the media in reporting e-sports in earlier years, today’s reports are more speculative and less cautious.

　　Chen Can’s mother and Jason’s father, as the deepest appreciators of the serious harm caused by Internet addiction to teenagers, strongly oppose the increasingly obvious high profile of e-sports.

　　E-sports and video games are different, but they are all based on video games. Children only see some media speculating on e-sports, so they have a tough reason to resist parents’ restrictions on playing games. But how many children can become world champions from an internet addiction teenager?

　　Chen Can’s mother said, "For the development of e-sports, the state should have legislative supervision. Whether children can take the road of e-sports in the end depends on the evaluation of authoritative institutions to tell them whether they are suitable for the development of e-sports. Of course, we can’t completely ban e-sports, but we can’t mislead most children like this. "

　　Jason’s father said, "Successful e-sports players are only a small part of the pyramid. It is actually very difficult to take the road of e-sports. In my opinion, the media should publicize it comprehensively and make minors and parents aware of this problem. Now, they only see the bright side, but rarely notice that it is impossible for everyone to become a professional player in e-sports, let alone win the championship. We can’t let it (game makers) dominate public opinion. We want everyone to clearly see the harmful aspect of Internet addiction. "

　　In addition, Jason’s father also thinks that it is difficult for the state to strengthen the supervision of online games so that children don’t play at all, so the key is how to control them. Parents should also analyze why some children are addicted to online games and some children are not. The deeper reason of addiction is family education, so it is necessary to help children enhance their psychological quality and anti-frustration ability during their growth.

　　For video games to expand publicity in the name of e-sports, Tao Ran’s suggestion is that e-sports must be over the age of 21 or 22 (equivalent to graduating from college) to participate. This avoids the participation of teenagers and young people whose brains are developing and whose "three views" are being established. E-sports can be played, but it must be played by adults over the age of 21 or 22. Tao Ran found that 80% of teenagers with Internet addiction wanted to become e-sports players, which actually became an excuse for them to indulge in online games.

　　As far as schools are concerned, schools and teachers should publicize the dangers of excessive use of computers, electronic products and addiction to games just as they do anti-drugs. Instilling children with this danger from an early age may sprinkle venom in their hearts and sow the seeds of defense.

　　In addition, schools and parents should encourage children to develop more hobbies. Tao Ran said that teenagers with Internet addiction have a common problem — — There are few hobbies, and parents have not cultivated their hobbies well since childhood. They only have to study, and suddenly they come into contact with this game, which must be interesting. Another is to cultivate children’s good interpersonal relationships from an early age. Now there are many only children, and children have no playmates, so they can only play computers and mobile phones. Tao Ran suggested that parents should raise a small animal for their children to release their energy and let them learn to care about others. In addition, parents should reduce or even eliminate electronic nanny products in the process of children’s education. Children under 8 years old are not recommended to touch video games. Children over 8 years old can play for half an hour every day from Monday to Friday and for one hour every day on weekends.

　　In the past two years, there has been more and more publicity about e-sports in public opinion. Tao Ran believes that this is because some of our game manufacturers actually hold the tools of public opinion, which are the media while developing games. If the enterprises selling tobacco have mastered the media tools, can it still say that smoking is harmful to health? Therefore, game manufacturers will use their own media platforms to talk about the infringement of games on children, and say that games need to be controlled? An enterprise that grasps public opinion will certainly sing a song of praise for what it has developed.

　　Then, as a game manufacturer, at the same time, it holds a powerful tool of public opinion. Is this inappropriate? Should we have a system similar to the Anti-Monopoly Law, forcibly divest the media platforms of these companies, or split enterprises?

　　E-sports entering the Asian Games and possibly entering the Olympic Games is a hot topic of public opinion in recent two years, and it is also a powerful starting point for e-sports to carry out image innovation. However, the so-called competition of electronic games itself is still controversial.

　　In September last year, Yi Jiandong, a famous sports scholar, put forward "Identification of Ten Problems in E-sports in China", pointing out that "E-sports, as a new intellectual competition and spiritual entertainment, is different from sports that seek to strengthen physical fitness or physical limits, and can develop independently according to its own laws. Putting e-sports into the sports system has many adverse effects on itself and sports, especially on the concept and value system of sports. The development of e-sports in China is under the special background of the immature youth sports in China, the highest myopia rate in the world, the prevalence of chronic diseases, the poor fitness atmosphere, and the seriously low fertility rate. It is necessary to get rational policy regulation and even levy special taxes on the industry in order to gradually achieve the coordinated effect of social economy and culture. The author suggests that the government and even e-sports investors support large-scale and long-term research on the defects, drawbacks and deficiencies of e-sports, so as to form an objective, fair and balanced e-sports research and communication pattern, thus realizing the rational, peaceful and sustainable development of e-sports. "

　　Last December, at the Seventh Olympic Summit Forum hosted by the International Olympic Committee, some participants believed that the game industry where e-sports is located is business-driven, while sports is based on values. There is a huge difference in the basis of existence, which is why it is difficult for e-sports and sports to reach the same goal by different routes.

　　Yi Jiandong said in "Identification of Top Ten Problems of E-sports in China", "From the current point of view, the IOC’s project selection rules and practices do not support the possibility of e-sports becoming an Olympic project in the near future."

　　Beijing, February 18 th

Hello, everyone, today we share how I keep fit during the season. I hope you like it!

In 2020, Joshua kimmich scored the winner in the match with Dortmund. In that match, he ran 13.73 kilometers. This is the sport of football and kicking. In this sport, most of the running is not jogging, sprinting, walking, jogging and then sprinting. Because of this, the best way to improve physical fitness is to carry out high-intensity training.

We can achieve this goal by sprinting or intermittent training, but the least boring way to improve physical fitness is to use the ball for high-intensity training, which is also the focus of today. Today we will share the training methods to keep in shape during the season. Let’s officially start:

warm up

Before we start training, make sure that we have fully warmed up, do some dynamic stretching and sprinting, so that all our fast muscles will be activated, thus reducing the risk of muscle strain. Take 10 minutes to relax, and then start formal training.

This is the only part that does not include the ball, and it is one of the very good agility and quick training.

We can find a friend, or install an application on our mobile phone, which can flash colors and numbers for us for 10 times as a group. I

When our cell phones flash or our friends shout out a color, we sprint to the sign plate and then go back to the middle. About 30 seconds, depending on the length of the interval. In short, do five groups and rest for 30 seconds between each group.

The rest of the training is divided into three small cycles. The first cycle is what we see now. Before Ronaldinho’s dribbling training and shooting, he makes a 30-yard sprint dribble.

This training is great, because it can train our dribbling speed, dribble in a narrow space, and persist in dribbling when we are tired.

It’s a hard training, but it’s important for us to keep high shooting quality. Imagine that we will be very tired in the 80th minute of the game, so even if we are tired, we should be able to shoot correctly.

Figure 6- Correct Shooting

In this cycle exercise, we can jog or walk back to the starting point as a break between repeated exercises.

If we only have one or two balls, run after them, make sure we are jogging, then jog back to the starting point, and then give yourself an extra 30 seconds to rest.

In addition, because it takes a long time to start each action, you should do it for 15 minutes before continuing this circular action, and it should be very fast.

Before entering the second cycle, give yourself three to five minutes to rest. We should make sure that each cycle has intensity, and even if we are tired, we should work 100%.

In the second cycle, we make 10 passes to the wall, then zigzag dribble to practice turning and dribbling, then rush out and beat the last sign plate with one of our actions.

Put the sign plate 8 to 10 yards away, make sure we don’t go straight through it, rush out of the sign plate for at least a few steps, then cut back the sign plate and walk back to the starting point.

Once again, this is our break time, and a sign plate is set for passing the ball on the wall to ensure that we keep good habits when passing the ball and that we will not be lazy.

This cycle improves our ability to pass, touch the ball with the first foot, dribble and cut inside with the ball, and the ability of all 1V1 to beat the defender.

All this will make our leg muscles stronger, and at the same time enhance our heart and lung function. Do it for 10 minutes, and then rest for three to five minutes before continuing.

Figure 11- Cardiopulmonary Enhancement

The hardest part was left to the end. Many people hated doing this exercise, but it was the simplest exercise, and it was timed in 10 minutes.

Start by running back and forth, run to the small restricted area and then run to the penalty spot at the back, then run to the top of the restricted area and come back.

After the round-trip run, start bouncing the ball as soon as possible, don’t rest for a few seconds before starting, and then bounce the ball 30 times before starting the next round-trip run.

The key point here is that if we screw up and drop the ball, then we need to start the next round trip immediately, which puts pressure on the ball-passing part to ensure that we concentrate on the ball-passing and strive to maintain the quality.

If we don’t have this kind of pressure, then we will drop a few times, then pick up the ball on foot, and then continue to bounce the ball and give ourselves a long rest. After 10 minutes, we have finished the hardest part, but we are not completely finished.

Although this is not the main part of training, it is very important to do 5 to 10 minutes of cold-body exercise, which will make our muscles less tense and help us recover from the next training.

Don’t skip this link, do some static stretching or the same dynamic movement as before, but with less intensity.

That’s all for today. Please continue to pay attention to the road of football for more exciting football teaching!

　　Xinhua News Agency, Hong Kong, December 5 (Reporter Meng Jia) According to the Civil Aviation Department of the Hong Kong Special Administrative Region Government, the C919 and ARJ21 aircraft independently developed by the state will visit Hong Kong for the first time on the 12th and stay there until the 17th. This will be the first time that a C919 plane has visited a city outside the mainland.

　　ARJ21 is the first turbofan regional aircraft designed and manufactured independently by China. It was put into commercial operation in 2016 and officially delivered to overseas customers in 2022, and entered the international market. C919 is a large passenger plane designed, manufactured and certified for airworthiness in strict accordance with internationally accepted airworthiness standards. The first commercial C919 was delivered to airlines in December 2022 and put into service in 2023. The successful development of these two passenger airliners is an important milestone in the national aviation manufacturing industry.

　　The event was jointly organized by the Civil Aviation Department of the Hong Kong SAR Government and the Hong Kong Airport Authority. Commercial Aircraft Corporation of China was invited to send C919 and ARJ21 aircraft to visit Hong Kong.

　　Li Jiachao, Chief Executive of the Hong Kong Special Administrative Region, welcomed the first visit of C919 and ARJ21 aircraft to Hong Kong. He said that this fully reflects the country’s emphasis on the development of Hong Kong’s aviation industry and Hong Kong’s role as an international aviation hub. The 14th Five-Year Plan and the Outline of Guangdong-Hong Kong-Macao Greater Bay Area Development Plan clearly support the consolidation of Hong Kong’s position as an international aviation hub.

　　One of these two types of aircraft will arrive at the Hong Kong International Airport on the 12th, and will be statically displayed in a fixed area of the Hong Kong International Airport, and representatives of the aviation industry, youth groups and regional organizations will be arranged to board the plane for a visit.

　　Another highlight of this activity is the flight demonstration on the 16th. If weather conditions permit, the C919 will take off from Hong Kong International Airport, fly over Victoria Harbour and fly around Hong Kong Island twice. At that time, the public can have a glimpse of the domestic large aircraft.

　　On the afternoon of 16th, representatives of Comac China will be invited to meet with teenagers at the headquarters of the Civil Aviation Department to share their knowledge about the two aircraft. Two planes will leave Hong Kong and return to Shanghai on the afternoon of 17th.

　　Liao Zhiyong, Director of the Civil Aviation Department of the Hong Kong SAR Government, said that since 2012, the National Civil Aviation Administration has invited the Civil Aviation Department to participate in the preliminary work of the research and development of the C919 aircraft, and the Civil Aviation Department has been actively participating. Liao Zhiyong was very excited and looking forward to the opportunity to witness the flight of C919 over Hong Kong, and thanked the Civil Aviation Administration of China and Comac China for their full support and cooperation.

　　Zhongxin Jingwei Client May 23rd (Zhang Yunan) CPI data of 31 provinces in April 2019 have been released one after another, and hot topics such as "Garlic You Bite", "Cherry Freedom" and "Toona sinensis Freedom" have recently returned to the public’s field of vision. Under the strong siege of vegetable prices and fruit prices, what are the CPI performances of the provinces?

　　CPI in 16 provinces rose more than the whole country.

　　In April 2019, the national consumer price rose by 2.5% year-on-year, continuing to be in the "2 era". In food, the price of fresh vegetables is still at a high level, rising by 17.4% year-on-year, affecting the CPI increase by about 0.43%; Pork prices rose by 14.4%, an increase of 9.3% over the previous month, which affected the CPI increase by about 0.31%. Last autumn, the fruit harvest in the north was poor, and this year’s stock was insufficient. The price of fresh fruit rose by 11.9%, which affected the CPI increase by about 0.22%.

　　From the perspective of 31 provinces in China, according to the incomplete statistics of Sino-Singapore Jingwei client, the CPI of 16 provinces rose more than the whole country in April, with the highest increase in Tianjin, Hebei and Anhui, reaching 2.9%; Hunan and the national CPI rose flat, up 2.5% year-on-year; The increase in Beijing and Xinjiang was small, at 1.6%.

　　Don’t look at the classification, there are 13 provinces with a year-on-year increase in fresh fruits over the whole country, and Anhui has an increase of 30.9%, the largest increase; Only the fresh fruit in Ningxia rose by more than 20%, which was 20.4%; There are 18 provinces with an increase of over 10%, with a large number; Qinghai rose by 1.9%, with a small range.

　　In addition, there are 10 provinces where the year-on-year increase of fresh vegetables exceeds the national level; Chongqing and the national fresh vegetables rose at the same level, at 17.4%; There are three provinces with an increase of less than 10%.

　　On pork, from the provinces that have announced the increase, Anhui has the largest increase, reaching 24.7%; Followed by Sichuan, up 23.4%; The lowest is Guizhou, up 7.6%.

　　Is it really so difficult to achieve "fruit freedom"?

　　Following "Toona sinensis Freedom", "Garlic You Are Malicious" and "Cherry Freedom", "Fruit Freedom" has also been screened on the Internet recently, which has aroused heated discussions. In fact, after the Spring Festival, the news about the price increase of fruits is endless. It is even reported that the fruit price in Beijing Xinfadi wholesale market has generally increased by 78% compared with the same period of last year.

　　The Zhongxin Jingwei client combed the website data of the Ministry of Agriculture and Rural Affairs and found that the price of Fuji apple has been rising for 9 weeks in a row among the five fruits it focuses on monitoring. As of mid-May, the price of Fuji apple was 10.33 yuan/kg, up 60.7% year-on-year. In addition, the price of watermelon has been on the rise year-on-year. As of mid-May, the price of watermelon was 4.86 yuan/kg, up 29.7% year-on-year.

　　It is worth noting that the retail price of fruit is also "rising". According to the data of Hunan Provincial Department of Commerce, from May 15th to 21st, the number of seasonal fruits on the market decreased, the purchase price of producing areas increased, and the average retail price of fruits increased. The retail prices of six kinds of fruits monitored mainly increased by 3 and decreased by 3, and the overall average retail price increased by 0.28% from the previous month. Among them, the prices of grapes, apples and pears rose by 1.01%, 0.52% and 0.2% respectively.

　　According to the data of Zhejiang Provincial Department of Commerce, from May 6 to 12, the purchase and sale of the market dropped in the week after May 1, and the overall price rose slightly, with the price of fruits and eggs rising at the top. The wholesale market price of fruit rose by 1.7%, and the supermarket price rose by 3.7%. At present, there are many kinds of fruits in the market. The average price of cherries, loquats, cantaloupes and watermelons in other producing areas has increased due to the stacking of transportation costs in other places, low early adopters and high prices.

　　Is "fruit freedom" really hard to achieve? In response, Liu Aihua, spokesperson of the National Bureau of Statistics, responded on May 15th that the prices of fresh vegetables and fresh fruits are obviously affected by seasonal factors of extreme weather, and these seasonal short-term shocks are not sustainable, so the price increase of fresh vegetables and fresh fruits will not last at a high level.

　　Haitong futures also analyzed that the recent increase in fruit prices was attributed to the severe weather in the north and south fruit producing areas in 2018-2019. Therefore, in the gap period of the current fruit market, the summer melon fruits with large output have not been listed yet, the fruit stocks in the north have basically bottomed out last year, and the tropical fruits in the south are expected to reduce production. Under the influence of multiple factors, the fruit market price has been rising.

　　As for the worry that the "cherry freedom" of the screen is difficult to achieve and the ordinary "fruit freedom" is lost, some institutions think it is unnecessary anxiety. The price of fruit is determined by market supply and demand, and the price increase is a short-term phenomenon. With the adjustment of the market, the tide of fruit price increase may end.

　　Haitong futures said that in the short term, after June, summer fruits will be listed in large quantities. Although the production of litchi, longan and mango in the southern tropical fruit producing areas is expected to decrease, the output of mainstream fruits such as watermelon, cantaloupe and peach is expected to maintain the normal level in previous years, while the output of bananas and oranges is expected to increase slightly. Therefore, the overall supply of summer fruits is sufficient, and "fruit freedom" can still be expected.

　　CITIC Jiantou also analyzed that from the historical market, after experiencing a short-term price increase in the second quarter, fruit will gradually fall back and remain in a relatively stable range. This is mainly due to the production pressure caused by the interference of weather factors. After the price increase in the second quarter, it will be released, and the listing of new fruits in the later period will further stabilize the price. Therefore, fruit prices do not have the conditions for a sharp rise, but there will be a wave of rising prices in the short term.

The 11th issue of "Children’s Great Health", the first nationwide variety of children’s lifestyle health assessment named by Jin Lingguan, will be broadcast on Zhejiang Satellite TV at 17:00 on Sunday, July 29th. Chen Yibing, the Olympic champion, and his wife, Dan Jingti, appeared, revealing that their mother had pinched their noses when they were young. The reason is that pinching their noses can make their noses stiff. Is it true or not that pinching your baby’s nose can stand the bridge of your nose? Liu Jia, Deputy Chief Physician of Acupuncture Department of Guang ‘anmen Hospital, Chinese Academy of Traditional Chinese Medicine, will give an on-the-spot explanation and lead everyone to learn the beautiful baby development plan.

Beautiful cute babies are loved by everyone. With the improvement of living standards, parents not only attach great importance to their children’s nutrition and health, but also break their hearts about their baby’s "face value". Many parents have also tried some tips circulating in life, such as pinching the nose can make it stiff, shaving the eyebrows can make the eyebrows thicker, and smoothing the baby’s ears to make it more rounded. Chen Yibing broke the news at the scene, and when he was a child, his mother pinched his nose. Chen Huan humorously teased, "So it’s very good now.". Chen Yibing’s wife, Dan Jingti, said: "I don’t think it’s much help, because my mother pinched it for me when I was a child, but it didn’t help." Chen Yibing and his wife were both pinched by their mothers when they were young, but the effect seemed to be different, so they didn’t pinch their daughters’ noses. Many guests present said that they were pinched by their parents when they were young, so they would pinch their babies’ noses.

However, is this "ancestral" tip of the nose useful? Dr. Liu Jia answered questions from many parents on the spot: "Pinching the nose will not have an essential impact on the child’s bone structure. On the contrary, because children’s nasal mucosa is delicate and rich in blood vessels, if they pinch their noses too hard, they will damage their nasal mucosa and blood vessels, so this practice is not recommended. " Dr. Liu Jia also explained the "danger triangle" of human face: the nose is full of rich blood vessels, which communicate with the skull. Once congestion and infection are caused in these places, these bacteria can easily reach our skull and cause some serious diseases. Therefore, Dr. Liu Jia suggested that parents should try not to pinch their children’s noses. In this program, Liu Jia, a doctor, and Liu Suiqian, a nutritionist, will introduce how to cultivate beautiful babies through nutritional supplements and medical tips. Pay attention to small details and achieve great health! Please pay attention to this Sunday at 17: 00, Zhejiang Satellite TV Golden Collar "Children’s Great Health"!
