Original title: Why are there many industrial and commercial halls in Chongwai area?

　　The traffic location is convenient for businessmen.

　　According to the Records of Place Names in Chongwen District, there are 154 halls in Old Chongwen District. Although some of them are called fellow country halls, they are actually industry or industrial and commercial halls. There are not many halls that really serve the literati who came to Beijing to take the exam. There are only two halls, Jizhou Trial Hall and Zunhua Trial Hall, which are called trial halls, which are different from other halls.

Linfen Guild Hall, located in Ximaochang Street, is more than 400 years old, and was jointly built by five elements merchants in Linfen, Shanxi.

　　Historically, Shanxi businessmen and Shandong businessmen once dominated Beijing’s economy. Lu ‘an Guild Hall, which was once located in the south of Guangqumen Inner Street Road (now around Anhua Building), was built by Shanxi merchants who engaged in copper, iron, tin and carbon. In the old days, the hardware industry regarded the old gentleman in Taishang as the industry god, so there was an old gentleman hall dedicated to the old gentleman in Taishang in the guild hall. According to historical data, Lu ‘an Guild Hall appeared in the Ming Dynasty, and it grew from small to large, becoming one of the great guilds in Beijing. The "Monument" in the hall in 1920 said: "There was a Shenlu Temple in the old Lu County Hall, and the room outside the courtyard was the tomb of Lu people. For example, offering sacrifices to the meeting, raising the life and stopping the coffin, to the managers of the three gangs of copper, iron and tobacco bags for the county people. " Lu ‘an Guild Hall has the Laojun Temple and the altar for offering sacrifices to the furnace god, because the hardware industry can’t do without smelting furnace, so it is natural to offer sacrifices to the furnace god in the Guild Hall, and the old place name of the Guild Hall was called the furnace holy temple.

　　Shanxi Linfen Guild Hall was established by Shanxi merchants, and Shanxi pigment merchants also built another pigment guild hall in Qingyun Hutong. Pigment is not a concept in the old days, it includes many building materials and daily necessities, and it is a big industry. According to the data of Beijing’s economic history, "the cover of the paint shop is a flower stick, which is more than a foot long. Generally, it is painted in five colors: red, yellow, black, green and blue, decorated with golden flowers and painted with golden paths". This kind of flower stick, also known as the Five Flower Stick, is said to be specially designed to beat the emperor who fainted, and Emperor Yangdi was killed by the Five Flower Stick. Later, the five-flower stick became the symbol of the paint shop. "This kind of cover is always hung, not if other shops hang it early and later, it is intended to be the monarch of Yongzhen."

　　The pigment shop also sells all kinds of waxes, such as Jingyang Yellow Wax and Sichuan White Wax. In the years when there was no electric light, wax was mostly used for urban residents’ lighting, and wax was still a sacrificial object. When they got married, they were called "wedding night", and some scholars "read by candlelight at night", and candles were wax.

　　Linxiang Guild Hall, located in the eastern city of Chongwai, is also related to Shanxi merchants. It was established by Xiangling merchants in Linfen.

　　Cixi Guild Hall was established by a clothing merchant in Cixi, Zhejiang. Garment shops are shops that process, customize and sell garments. In 1923, there were 84 garment shops in Beijing. Shanxi cloth merchants built Jinyi Guild Hall in Xiaojiang Hutong, which was also called "Cloth Guild Hall" because it was built by cloth merchants among Shanxi merchants. According to "Atlas of China Cultural Relics", by the time of the Republic of China, Jinyi Guild Hall was no longer used as a cloth business meeting, but as a place for people from Yicheng, Shanxi Province to reunite in Beijing, and also provided free living services for people who went to Beijing temporarily. In 2011, Jinyi Hall became a part of Liu Laogen Hall.

　　In addition, Fujian paper merchants built Yanshao Guild Hall in Chongwai, while Yuanning Guild Hall was funded by Jiangsu silk merchants.

　　There are many historical reasons for "worshipping foreign countries" industries and industrial and commercial halls. Since the Ming Dynasty, the Grand Canal was cut in two due to the construction of the outer city. "The soil is getting higher and higher, and the boat can’t reach it." The pier of Jishuitan can’t be used anymore, and the terminal pier of the Grand Canal was changed under the Datong Bridge in Dongbianmen, not far from Chongwenmen. In addition to water transport vessels, there are many merchant ships at Datong Bridge Wharf. Merchants often unload ships here. Besides building warehouses and warehouses in Chongwai, they also build industrial and commercial halls. They live in the halls to facilitate business.

　　Since the Ming Dynasty, Chongwenmen has been a very important tax gate. At the end of Qing Dynasty, Prince Su once supervised Chongwenmen’s tax gate. He honored the collected taxes to "Lafayette" and became Cixi’s "rouge money" for her to squander at will. It is said that many of Beijing’s "official residences" were built by her with uncountable rouge money, and she profited a lot from them, which shows that the amount of tariffs and taxes in Chongwenmen is large. After paying taxes, most businessmen live in Chongwai area nearby. They don’t live in chicken feather shops, but prefer private residences. Of course, the most convenient place is the clubhouse built by peers. As a result, it is normal that there are many industrial and commercial and trade halls in Chongwai area.

　　In addition, Chongwai area is the hometown of handicraft industry in history, and all kinds of products have become the source of goods for merchants from all walks of life. Vendors from all over the world bargain and discuss business here. Merchants will build some halls in Chongwai nearby. Although some halls are nominally literati test halls, the imperial examination is held once every three years, and people in the industrial and commercial circles mainly live in them on weekdays. It is natural that there are many industrial and commercial halls in Chongwai Hall.

　　Handicraft developed and business prospered.

　　There are many industrial and commercial halls in Chongwai area, which has a lot to do with the development of handicrafts here. Since the Ming and Qing Dynasties, in addition to many small weaving factories, hosiery factories, hemp rope factories and towel factories, handicrafts such as paper, silk, paper and flower, filigree inlay, cloisonne, ivory carving and feeder have been worshiped abroad, especially around Huashi Street, where they have grown and developed, leaving an unforgettable page.

　　In the 1920s, Beijing Practical Guide made statistics on handicraft workshops and shops in Chongwai area. For example, there are 9 Cui Hua Bureau (making glass jadeite); There are 18 paper flower shops, most of which are in the flower market. There are 13 hemp rope shops, 14 hemp shops and 4 official hemp shops. Chongwenmen was the gate of liquor import and export in history. There was a great demand for wine baskets in that year, and there were as many as 13 shops buying and selling wine baskets in Chongwai area. Interestingly, the shops that buy and sell shoulder poles are also concentrated in the flower market area, with 8 shops. There are 6 feeder shops, and all the mirrors in Beijing are laid in four flower markets, totaling 11.

　　In 2008, Donghuashi Street also made statistics on the shops and workshops in Donghuashi Street in the 1940s, and made the brand "Flower Market Store Directory". There are more than 300 shops recorded in the store directory, mainly Donghuashi Street, excluding Xihuashi Street and the surrounding hutongs, among which there are four paper flower velvet flower shops, and the velvet silk flower Trade Association is also in this street, with one feeder, one silk cutter, one inlay and one enamel shop (workshop) each.

　　The flower market is famous for its flowers, but the flowers here are not flowers, but velvet flowers, silk flower flowers and paper flowers, which are called "Beijing flowers". "Jinghua" was once an indispensable ornament for Beijingers, especially decades ago, middle-aged and elderly women wore bright red velvet flowers on their heads during the Chinese New Year holiday, which was very festive from a distance. Flowers bloom for a short time in the north, and there are seasonal restrictions. People who love beauty decorate the environment with silk flower and put silk flower in a vase to make the room full of spring scenery. As for paper flowers, wreaths are mainly made, and all kinds of flowers have their own uses. The "Jinghua" industry was once very prosperous. According to the "Overview of Industry and Commerce in Beiping", in old Beijing, "there are more than 1,000 flower growers in various markets and homes."

　　The "Jinghua" workshop in the flower market generally does not do all the work, but has a clear division of labor. Some specialize in flowers, some in pistils, some in leaves, and some people or workshops assemble them into finished flowers. "Every morning, thousands of people gather in the flower market to display their products in the market". In addition to retail, larger stalls and "Flower Village" run wholesale and sell "Jinghua" to all parts of the country. In the development of "Jinghua", large-scale merchants, such as flower shops and flower villages, appeared to specialize in the sale of "Jinghua".

　　The technical content of making "Jinghua" is not high. Assembling flowers, stamens and branches is called "saving live". Adults and children can do it, which has solved many people’s employment. In addition to being used as headgear and decorating life, "Jinghua" merchants also provide services for opera artists and act as "outfits". Famous artists such as "Hua Er Liu", "Hua Er Gong" and "Hua Er Jin" have emerged in Beijing Flower Industry. Hemp rope is an indispensable material for Beijing gardeners, so there are many hemp shops in Donghua Market alone. Later, plastic flowers appeared on the stage, and velvet flowers and silk flower plummeted. Coupled with changes in folk customs, not many people wore velvet flowers. "Jinghua" basically doesn’t exist, except for those who make wreaths, and even "Jingyi silk flower Sales Department" has disappeared.

　　In addition to the flower industry, there are many handicrafts in Chongwai that are unique in Beijing, such as filigree mosaic, which is very famous. Filament inlay is a traditional handicraft in China. It processes gold and silver into filaments, shapes them by pushing, pinching and weaving, and engraves patterns on the gold and silver filaments, and then inlays them with beautiful pearls, jade and precious stones. The products inlaid with filigree can be roughly divided into three categories, one is jewelry, the other is display and decoration, and the other is to decorate filigree with some daily necessities. Nowadays, filigree mosaic has become a national intangible cultural heritage.

　　The feeder is also an ancient industry. The grape feeder made in the famous "Grape Factory" is as shiny and shiny as a real grape. The grape feeder is inherited by the "Chang sisters" who originally lived in the flower market. They are Mongolians. In order to keep this craft secret, the Chang sisters never marry. Their deeds are often seen in newspapers. Scholar Deng Tuo once wrote: "The two generations of the Chang family kept the cold, and a hundred years passed down. The purple color of the grapes damages the beauty, and the old dreams are like smoke! "

　　There are many kinds of feeders in old Beijing, except grapes, peaches, fruits, pears, flowers, animals and people can be confused. The feeder takes glass as the main material, and the handicrafts made are colorful, ingenious, lifelike, exquisite, crystal clear and lovely, and are loved by people. In 1964, the feeder company built a building near Longtan Lake, and more than 800 people were engaged in feeder production. Prior to this, feeder artists were all based on families or workshops, distributed in Huashi Street and surrounding alleys, which should be the birthplace of old Beijing feeders in Huashi area.

　　Cloisonne, also known as inlaid enamel, is a kind of ware made of fine copper wire woven into various patterns on a copper tire, and then the enamel glaze is mainly blue and filled in the patterns. Cloisonne craft has a history of 600-700 years in China, and it is called "Cloisonne" because of its high development, exquisite technology and various varieties during the Jingtai period in the Ming Dynasty. Before the Japanese invaders invaded China, cloisonne products in Beijing sold very well, and most of them were exported to Europe, America and Japan, and the Japanese secretly copied them. At the time of its prosperity, there were nearly 100 cloisonne workshops with more than 2,700 employees. Dexingcheng, the second lane in Chongwai, and Da Rui Hall in Tea Hutong are among them. In 1923, there were 15 "Jingtai enamel shops" in Beijing, specializing in cloisonne products. In 1950, Beijing Enamel Factory was built in the south of the Temple of Heaven, and the road next to the factory was named Jingtai Road.

　　Chongwai is known as the hometown of handicrafts and the birthplace of many handicrafts in Beijing. The "Hundred Workshops" established a few years ago confirmed the prosperity of Chongwai handicrafts. Before 1990, there were glassware factories, feeder products factories, art red light factories, craft woodcarving factories, jade factories, theatrical outfitting factories, etc. Many handicraft factories gathered in the same area, which explained the origin of industrial and commercial halls in Chongwai area from the side.

Changjiang Daily Media February 1 (Reporter Wu Ye correspondent Ma Yaoyao) As the Spring Festival approaches, many citizens are busy buying new year’s goods. The doctor reminded that people must pay attention to avoiding the "pit" of allergies when they choose to buy new year’s goods with great joy. The Changjiang Daily reporter learned that the dermatology and ophthalmology clinics in Houhu Campus of central hospital of wuhan recently received many patients with related diseases caused by allergies when buying new year’s goods.

Men itch all over after visiting flower shops.

Mr. Liu, 43, lives in Houhu. On the afternoon of January 31, he and his wife went to the flower and bird market to buy some flowers and green plants to decorate the room and increase the atmosphere of the Spring Festival. After coming to the flower and bird market, Mr. Liu didn’t expect that there were not only many kinds of flowers and plants in the Spring Festival atmosphere, but also various meanings. Every time he went to a flower shop, he had to watch them carefully, listen carefully to the boss’s explanation of breeding methods, and sometimes touch the leaves with his hands and put his nose together to smell the flowers.

Not long after returning home, Mr. Liu suddenly felt itchy. After undressing, he was shocked. He found many erythema and wheal on his back, arms and abdomen. Thinking that it was getting late, he didn’t go to the hospital immediately. He endured until the next day and found that his body was more itchy, many skin were scratched, and diarrhea symptoms appeared. The dermatologist in Houhu District of central hospital of wuhan diagnosed that Mr. Liu had urticaria, and further examination revealed that he was allergic. At present, after drug treatment, Mr. Liu’s symptoms have been significantly improved.

Gao Ying, director of dermatology department, said that before the Spring Festival every year, many patients who were exposed to allergens during the purchase of new year’s goods would be admitted to the clinic, causing acute urticaria. Plants themselves are an important class of allergens. The roots, stems, leaves, flowers and fruits of plants can produce allergens. When they enter the human body through ingestion, inhalation or contact, they will induce allergic diseases under certain conditions.

Director Gao reminded that in winter and spring, we should try our best to avoid going to places where there are many flowers, plants and dust mites. Once citizens find that they have symptoms of urticaria, they should go to regular hospitals for examination in time. acute urticaria patients can be cured by taking drugs regularly for one week. However, chronic urticaria can be formed if it is not treated in time or exposed to allergens continuously. Chronic urticaria is difficult to cure, and symptoms can only be controlled through long-term medication.

The eyes of female white-collar workers are itchy after makeup.

Lily, a 25-year-old female white-collar worker, went to many shopping malls to try on cosmetics in order to wear a heavy makeup at the company’s annual meeting, and also bought some good cosmetics for herself for the New Year. Unexpectedly, the next day, her eyes showed symptoms of tears, photophobia and strange itching, and she was diagnosed with allergic conjunctivitis by eye examination in central hospital of wuhan. By further inquiring about her illness, the doctor who attended the clinic learned that Lily usually loves dressing up and never goes out without makeup. Eyeliner, mascara and Cosmetic Contact Lenses are all essential steps. The doctor judged that she tried a variety of cosmetics at the weekend, so that the use of cosmetics around her eyes led to allergic conjunctivitis.

Xiang Yi, director of ophthalmology, said that allergic conjunctivitis is now caused by improper use of cosmetics, wearing contact lenses and pollen, and its incidence is gradually increasing. The main symptoms of allergic conjunctivitis are tears, photophobia and even itching.

Director Xiang reminded that in recent years, cosmetics have also become the new year’s goods selected by young women who like fashion during the Chinese New Year. Cosmetics themselves contain many chemical synthetic substances, which constantly stimulate the tissues around the eyes, which may cause conjunctival allergy and allergic conjunctivitis. Citizens should stay away from inferior cosmetics. People with allergies should stop immediately after using cosmetics and go to the hospital in time.

　　In order to ensure that critically ill patients can receive timely priority treatment, the reporter learned from the Beijing Municipal Hospital Administration that from May 1, 2019, 20 Beijing-owned hospitals providing emergency services will uniformly implement emergency pre-examination and triage ("emergency classification").

　　According to the former Ministry of Health’s Guide to the Construction and Management of Emergency Department (Trial) (Wei Yi Zheng Fa [2009] No.50) and the national health industry standard "Standardized Process of Hospital Emergency Department" (WS/T390-2012), it is clearly put forward that "emergency departments should formulate and strictly implement triage procedures and triage principles": patients should be divided into "endangered, critical, emergency and non-emergency" 1.

　　Level 1 patients are in critical condition and may be life-threatening at any time, and immediately enter the resuscitation room or rescue room for rescue. Such as cardiac arrest, shock, definite myocardial infarction, status epilepticus, body temperature > 41℃, systolic blood pressure < 70mmHg, blood sugar < 3.33mmol/L, etc.

　　Grade 2 patients are critically ill or rapidly deteriorating and life-threatening, and enter the rescue room for treatment within 10 minutes. Such as severe dyspnea, lethargy, acute stroke, ECG suggesting acute myocardial infarction, active or severe blood loss, etc.

　　Grade 3 patients are in an urgent condition and have potential life threats, and priority is given to diagnosis and treatment before grade 4 non-emergency patients. Such as acute asthma, foreign body inhalation, dysphagia, persistent vomiting, chest and abdominal pain, mild and moderate trauma, mild and moderate bleeding, etc.

　　Grade 4 patients are non-emergency, and the degree of illness is average. According to the guidelines, the waiting time is longer. Such as mild pain without dangerous features, minor abrasions without suture, follow-up visit of patients in stable recovery period, and only issuing medical certificates.

　　How to achieve scientific classification and give consideration to fairness and safety? According to reports, first of all, the emergency departments of all hospitals have arranged experienced personnel to engage in emergency pre-examination and triage, and organized all medical staff related to emergency to conduct special training for all staff; Secondly, the most important basis for grading is the collection of patients’ vital signs by professional instruments, including heart rate, blood pressure, blood oxygen saturation, etc., and the medical staff will combine the patient’s medical history, symptoms and signs to make the final scientific grading and subordinate to the specialty; Third, professionals monitor the condition of patients in the waiting area. For Grade 3 and Grade 4 patients, when waiting in the waiting area, there will be specialized medical personnel to patrol regularly to dynamically evaluate the condition and potential risks of the patients waiting for treatment, and they can be graded again according to the latest evaluation to ensure the safety of patients. If the patient has sudden discomfort, please inform the medical staff in time so as to take corresponding medical care measures in time.

Short video news is changing people’s habit of watching TV news for a long time. The All Media School had previously paid attention to the trend of Washington post’s short video strategy. Today, it once again focuses on methodology. How short video is the most popular?

The Journalist’s Resource website synthesizes many reports and sorts out the essential tips of video editing. To get the best "input-output ratio" of news video production, we need to figure out how long it is most appropriate!

In 2014, a report from the Pew Research Center showed that in the United States, more than 6 out of 10 adults had the habit of watching online videos, and 36% of them chose to watch news videos.

YouTube has more than 1 billion registered users, and the massive user viewing data can most intuitively reflect how long videos are the most popular.

As early as 2012, Pew Research Center began to study the video viewing data on YouTube, and concluded:The most popular video is about 2.1 minutes long.. This video is slightly longer than the local TV news, but shorter than the online evening news collection.

Research institute ComScore found in a report in 2014 that,The average duration of online video (excluding online video advertisements) is about 4.4 minutes.

The Tow Center Digital Journalism Research Center of Columbia University also published a multimedia research report in 2014, compiling the challenges faced by newsrooms, such as how media organizations try to use video as a profitable editing tool.

Although many organizations have published research reports, there is no "absolute standard" for the duration of news videos. This is because, to a great extent, readers’ tastes and standards are constantly changing.Therefore, in the discussion about the length of moving vertical video, there have been various opinions.

However, the latest research from the University of Texas at Austin provides some new perspectives.

The research team published their research results in the professional journal News Research this year, focusing on the quality and length of news videos, trying to find out the characteristics of news videos that attract readers and estimate people’s viewing preferences.

Peter S. Chen, the first author from the University of Texas, published a paper with two co-authors from the University of Southern Mississippi. The core findings are as follows:

1. High-definition image quality and information determine the "first impression"

Although previous studies have proved that if video content can arouse the audience’s interest, they can also tolerate low-quality video images.

But,Readers won’t tolerate pictures that are not informative, poor in texture and have no sense of pleasure.I will not recommend this to others.

2. Don’t ask the source of the video, talk about the hero by length.

It is found that it is most appropriate to keep the video content of a short video at 2.08 minutes. A slightly shorter video is most suitable in 24 seconds.

3. When both image quality and duration are taken into account, image quality takes precedence.

When both quality and length are considered, compared with other videos,People will prefer long and high-definition videos or short and high-definition videos.

4. Quality is paramount, and video editing also needs professional training.

The quality of a news video can affect the audience’s cognition of news organizations, and the longer the video, the deeper the cognitive impression.

In recent years, many editors are required to be able to produce and edit news videos, but they have not received professional training.

"This enables employees who lack professional visual training to post videos online, especially those short videos."And such reckless practices will leave a "bad impression" on readers.

"Just like the paper media dealing with the content crisis, publishing news videos online can only solve the problem of how to attract audiences by overcoming quality problems."The researchers stressed that other components of video still need more research. For example, audio quality and its composition, which is also an important factor for the audience to decide to start or stop watching.

Related research:

In 2011, a paper in the journal News Research proposed that "the more relaxed the content, the more clicks it can get" by studying YouTube videos. Of course, this is not to deny that traditional news videos can’t gather popularity.

　　Wang Chunying said that thanks to the outstanding export performance of high-end manufacturing and new energy vehicles brought about by China’s industrial transformation and upgrading, as well as the continuous expansion of new trade formats and new models such as cross-border e-commerce, China’s trade surplus in goods will remain at a high level. In terms of service trade, with the resumption of residents’ cross-border activities, cross-border travel expenditure is returning to normalization. China’s visa-free policy and the facilitation of payment for overseas Chinese who are being promoted by the People’s Bank of China and the Foreign Exchange Bureau will continue to boost the sustained growth of tourism revenue.

　　Wang Chunying introduced that in the first quarter of 2024, China’s travel revenue increased by about 30% year-on-year, and it is expected to continue to maintain a good momentum in the future. More importantly, in recent years, the service trade has developed with high quality, and the export of productive service trade has increased steadily. In 2023, the trade surplus of China Telecom’s computer and information services and commercial services totaled US$ 57.2 billion, which was at a historical high. Continued growth in the first quarter of 2024 will also help the balance of service trade to become more balanced.

　　Wang Chunying said that a series of measures will support the current account, including trade in goods, to maintain a relatively stable pattern in the medium and long term. In the future, China’s current account has the conditions and foundation to maintain a reasonable surplus.

　　Can be called "the first sport in the world", and the culture of football is profound.

　　According to Ge Weikun, a professor in Tsinghua University, this is exactly what China football lacks most.

　　At a speech meeting a few days ago, the old professor who studied physics unexpectedly talked about football and listed a lot of physical knowledge in football, which attracted the attention of many fans for a while.

　　As for China football, he once organized football matches for Chinese and foreign students overseas and led the team to win the championship. He put forward his own suggestions, "What we lack is football culture. Sending dozens of people out like the Jianlibao team can’t solve the problem. "

　　Physics professor studies football? You really have a doorway

　　As a senior physics professor in Tsinghua University, another identity of Ge Weikun is a fan.

　　It seems that the two fields have no intersection, but in fact they are inextricably linked.

　　As early as 2014, together with professors from other schools, he produced an open online video course called "Football and Science", and many people signed up for classes every year.

　　"Up to now, there are about 30,000 people who have participated." He told the The Paper reporter. At present, he is still working on compiling this video course into a book.

　　What made Professor Ge popular on the Internet was his knowledge of physics in football mentioned in a speech a few days ago, which was quite refreshing for fans who were used to tactical analysis.

　　And this knowledge comes from the courses he made before.

　　For example, why can Beckham’s banana ball "turn" the goal in a strange arc? In fact, it is because the rotating sphere is deflected by Magnus’ law in flight.

　　If you want to kick the "elevator ball" that suddenly falls, according to the parabola obtained by physical calculation, you need to make the ball have a high initial speed without rotating.

　　According to Ge Weikun, overseas, scholars have studied the science of football as early as ten years ago.

　　The relationship between the speed and angle of the interceptors in the middle of the interception, the average contact time of each person in a football match, the distance from the penalty to the goal and the goal rate &hellip; &hellip; All kinds of seemingly "unremarkable" data have actually been carefully studied.

　　Theory guides practice, and players can’t be "unlearned"

　　Perhaps in the eyes of fans, these academic football physics studies are not far from the actual playing &mdash; &mdash; After all, no one will measure the angle of the defender when passing the ball and then decide the passing strength.

　　But for players, these studies still have positive significance.

　　"In fact, the main purpose of (these studies) is to give a physical explanation of some phenomena in football, so as to give the technical essentials. When we understand the principle, we can know how to kick. " Ge Weikun said in an interview with The Paper.

　　"For example &lsquo; Elevator ball &rsquo; , it is necessary to (let the ball) not turn, to have a high initial velocity, you need a strong calf strength. Kick &lsquo; Banana ball &rsquo; , it is necessary to touch the ball on the inside of the foot to increase the friction time of the ball. Players are not required to know physics, but this is a scientific method. If the coach saw it, it should be helpful. "

　　In fact, for football, Professor Ge is really not "an armchair strategist".

　　Previously, he studied and taught overseas and lived for more than 20 years. In Britain, he played futsal with the local people, and in the United States and China, he organized a student football team to coach himself.

　　When he was in the United States, he participated in the organization of the first invitational tournament for Chinese and American student teams, and as a result, his team defeated Yale University 1-0 and won the championship.

　　In Ge Weikun’s view, football emphasizes teamwork and is definitely a sport that needs high IQ.

　　As for the cultural training of athletes, there is still room for improvement in China football.

　　"I think we may be right &lsquo; Football should start with dolls &rsquo; This sentence is misunderstood, which does not mean that children should play football all the time. Coach Jin Zhiyang told me that 90% of the young players can’t enter the professional team, and they have no education and a bad future. In the end, parents dare not let their children play football, which leads to worse and worse football in China. "

　　"Japanese coach takeshi okada also said that China’s young players have insufficient cultural education and logical thinking ability. It’s ok to play football, but when you become a coach in the future, it will be insufficient, which will lead to worse teaching. "

　　Football in China is still "unhealthy".

　　Although he is over 70 years old, Ge Weikun is still full of interest in football. He is a professor of physics and a member of Tsinghua University Football Research Center. He can even try his hand on the football field.

　　Like all China fans, he is also looking forward to the rise of football in China, but he has no secret about the problem of football in China.

　　"Football should be a pyramid. It is not enough to look at the spire. Sending dozens of people out like the Jianlibao team can’t solve the problem. (Still depends on) the campus football that is widely carried out now. "

　　In the process of living overseas, he has seen the profundity of local football culture, and China football, as the Italian marshal Cannavaro said, lacks most not money, but football culture and tradition.

　　"For example, in Germany, football has become a part of their culture, just like their music. There are many old people singing very well near the church there. On weekends, I don’t know how many football matches there are. "

　　"In China, football clubs are the names of enterprises, while club names in Britain are place names with strong local awareness. For example, Manchester City, when they were not as powerful as they are now, still has a large number of diehard fans. (Fans) will not only look at the team’s achievements, but also support them even if they are relegated to the second, third and fourth leagues. "

　　Nowadays, many measures have been taken to popularize football culture in China, such as promoting campus football and social football, and increasing the number of stadium facilities. In Ge Weikun’s view, these are all positive signals.

　　However, at the moment, Professor Ge also said, "The commercial flavor of the Super League is too strong, and some of them are not healthy. Football should have a higher value than business. "

　　CCTV News:May 20th is the full day of the 24 solar terms. At this time, the wheat is full of filling and enters the late stage of milk ripening, but it is not fully mature, just "small enough to be full", so it is called Xiaoman. From childhood to maturity, it is one of the busiest stages of farming in a year, and summer crops in various places begin to be harvested one after another.

　　The main producing areas welcome a bumper harvest, and Henan, the largest wheat province, has a bumper harvest in sight.

　　Summer grain is the mature grain in the first season of the year in China, and its output accounts for more than 20% of the annual grain, most of which is winter wheat. In 2024, the area of 11 major winter wheat producing provinces increased steadily, and the growth of wheat was generally better than normal, laying the foundation for a bumper harvest. At present, wheat has not been harvested in a large area in the Huang-Huai-Hai wheat area, where the output accounts for more than 80% of the country, but the processing market, agricultural machinery market and trading market have been busy. In Henan, due to the growth of food processing enterprises in 2024, the demand for high-quality wheat flour also showed an increasing trend.

　　Henan is located in the Huang-Huai-Hai Plain, and its perennial wheat planting area is more than 85 million mu, ranking first in the country. In terms of geographical conditions, the topography of Henan province is high in the west and low in the east, and the area of plains and basins suitable for large-scale agricultural cultivation reaches 93,000 square kilometers, which provides a good prerequisite for large-scale cultivation of wheat.

　　From the climate point of view, Henan is located in the middle of China, and sufficient light and heat resources provide favorable conditions for wheat planting. At the same time, the Yellow River, Huaihe River, Haihe River and other water systems also provide a guarantee for agricultural irrigation, making Henan a well-deserved "hometown of wheat", accounting for about a quarter of the national wheat production.

　　Henan is not only a major province of wheat production, but also a major province of wheat processing, producing one third of instant noodles, one quarter of steamed bread, three fifths of glutinous rice balls and seven tenths of dumplings.

　　The number of food processing enterprises increases, and the demand for wheat flour increases.

　　Luohe is one of the important gathering places for wheat processing in Henan. In 2024, there were 237 food industrial enterprises above designated size, 40 more than in 2023. In addition, these enterprises introduced new products every year, so the demand for high-quality wheat flour as the main raw material showed an increasing trend.

　　Unified seed supply and unified management to ensure that the quality of stored wheat reaches the standard

　　In order to ensure that the quality and yield of high-quality wheat can reach the standard stably, the consortium introduced social service organizations for unified seed supply and management.

　　Perception of "Three Summers" Change from Processing Market

　　At present, Henan wheat field is in the calm before large-scale harvest, but around the listing of new grain, farmers, cooperatives and processing enterprises have long been active. What are the new changes in 2024?

　　As the wheat harvest approaches, this flour processing enterprise in Wuyang County, Luohe City has been busy.

　　Yang Shuai, head of the enterprise, said that the biggest change in 2024 is that the planned harvest of high-quality wheat is much more, which was 18,000 tons in previous years and may exceed 40,000 tons in 2024. Because a single variety of high-quality wheat needs special collection and storage, he has to vacate more independent warehouses and special vehicles to keep the wheat from being mixed and ensure the purity.

　　Luohe is one of the important gathering places for wheat processing in Henan. Take the flour mill where Yang Shuai is located as an example, they meet the individual flour order demand of 28 food production enterprises, and according to these demands, they are transformed into seven specific high-quality wheat varieties, and then 53 cooperatives cooperating with the flour mill are guided to order planting by appropriately raising the purchase price. In this way, the demand for new products such as moon cakes, shrimp slices, Shaqima and spicy strips in the downstream of the industrial chain has been transformed into seven wheat varieties in the upstream of the industrial chain.

　　In Luohe, there are already seven such wheat industrial chain complexes. In order to ensure that the quality and yield of high-quality wheat can reach the standard stably, the consortium introduced social service organizations for unified seed supply and management.

　　Different from the plots under unified management, because of extensive management and mixed planting of different varieties, the wheat is uneven in height and the quality can not meet the processing requirements of special flour.

　　In recent years, driven by the whole industrial chain, Luohe has continuously guided large grain growers to increase production and income through standardized planting of high-quality varieties.

　　It is understood that in 2024, the area of high-quality special wheat in Luohe City reached 1,268,900 mu, accounting for 53.3% of the local wheat area, ranking first in Henan Province.

　　Do a good job in cross-regional operation support and disaster prevention and reduction

　　These days, wheat in Henan has entered the late filling stage, and it is expected that a large area will be harvested around May 25th, and the wheat harvest will last until June 15th. In just about 20 days, how to ensure that more than 85 million mu of harvest is available and the particles are returned to the warehouse?

　　2024 is the first year of China’s wheat yield increase action. Henan province focuses on increasing wheat yield per unit area, and promotes the integration of fertile fields, improved varieties, good methods, good opportunities and good systems. At the same time, in the high-standard farmland built-up area, we will focus on building 7 million mu of high-yield demonstration areas for wheat, integrate and promote high-yield technologies, and build a good harvest foundation.

　　During the "Three Summers" period, Henan plans to invest more than 4 million sets of agricultural machinery, including 200,000 sets of combine harvesters and 30,000 sets of crawler harvesters.

　　In view of individual lodging plots caused by recent extreme weather, Henan has formulated remedial measures as soon as possible, sent technicians to the front line for guidance, and sprayed potassium dihydrogen phosphate solution to promote wheat filling and minimize losses caused by disasters.

　　At the same time, in order to prevent the impact of extreme weather during harvest, Henan also supports various business entities to speed up the construction of grain drying facilities. At present, 580 drying facilities have been built, with an additional daily drying capacity of 37,000 tons.

　　"Three Summers" Science Popularization: Colorful Wheat with High Value and Connotation

　　When it comes to wheat, most people may think of yellow, but there is actually more than one color of wheat. Follow the doctor of agriculture to meet the colorful wheat with high value and connotation.

　　Xu Hao, a doctoral student in crop science at the Agricultural College of Henan Agricultural University, said that colored wheat is similar to ordinary wheat in appearance, but its grain color is not Huang Chengcheng in the traditional sense, but red and green. This is not late-maturing wheat, it has entered the filling stage and will be harvested in more than 20 days.

　　These are new varieties of colored wheat which are suitable for large-scale planting through a series of breeding methods such as physical mutagenesis, chemical mutagenesis and distant hybridization. Because they are rich in anthocyanins, they will show different colors on the seed coat.

　　Why study colored wheat? We are not interested in its showy appearance, but it is rich in protein, amino acids, trace elements and minerals, which are higher than ordinary wheat, and it has the potential to make people eat delicious and healthy!

　　These noodles and cereals made from it still look like traditional food, but they already have the function of health food. It is no exaggeration to say that they have high value and connotation!

　　CCTV News:In the past few days, many places in the country have ushered in the peak of returning home. According to the data of the smart car networking platform of the State Grid, as of February 5, the charging amount of new energy vehicles in the expressway service area on the platform has increased by more than 60% compared with the same period of last year. With more and more new energy vehicles joining the returning army, the "travel tide" has formed, and the "charging tide" of new energy vehicles has also appeared.

　　The data shows that in the 11 days from January 26th in Spring Festival travel rush to February 5th, the charging amount of new energy vehicles in the expressway service area reached 34,089,100 kWh, and the charging times reached 1,519,400, which were 67.06% and 48.42% higher than that in Spring Festival travel rush in 2023, respectively.

　　According to the platform data, during the Spring Festival travel rush in 2024, the peak period of the whole high-speed busy index reached 30%&mdash; 40%, which shows that among all the stations on the expressway, there are 30%&mdash; 40% of the stations are fully charged. At ordinary times, the charging busy degree of these stations is only about 10%, and the busy degree has doubled or tripled, showing an obvious tidal phenomenon.

　　Emergency charging compartment of mobile charging vehicle should deal with "charging tide"

　　In view of the "charging tide" brought by the "travel tide" of new energy vehicles, during the period of Spring Festival travel rush, many places in China took various measures to solve this problem.

　　It is predicted that during the Spring Festival in 2024, the average daily charging capacity of Jiangsu expressway service area will reach 600,000 kWh, a year-on-year increase of 70%, a record high. In order to alleviate the charging pressure, Taizhou power supply department has reformed 7 service areas and 14 charging stations within its jurisdiction, and equipped mobile charging vehicles. In Qinhu service area on Yanjing Expressway, a 120kW mobile charging vehicle is specially equipped, which can provide uninterrupted charging service for four electric vehicles at the same time.

　　In Pingwang Service Area, Wujiang District, Suzhou City, there are 16 charging parking spaces in the north-south direction. Since Spring Festival travel rush, affected by high-speed tidal phenomenon, eight charging parking spaces on the north side of the service area are basically full every day, but there are vacant parking spaces on the south side. Local staff guided some cars on the side with large traffic flow to the opposite idle service area for charging through the two-way culvert, which effectively improved the bearing capacity of the service area.

　　In Tianjin, in order to reduce the waiting time for new energy vehicle owners to charge on expressways, the local electric power department started the emergency charging cabin in the expressway service area on the one hand, and upgraded the charging facilities of 46 busy high-speed charging stations in advance. After the renovation, the average charging time was shortened by nearly 30%.

　　Scientific layout to ease the expressway "Charging tide"phenomenon

　　China has been speeding up the layout of charging piles, so that electric vehicles can alleviate the "energy-filling anxiety" of expressways. In the future, this phenomenon of "charging tide" is expected to be alleviated with the increasingly intelligent and efficient energy-replenishing network of expressways being gradually woven.

　　According to the data of the Ministry of Transport, at present, there are more than 20,000 charging piles in expressway service areas nationwide, covering nearly 50,000 parking spaces for minibuses. The coverage rate of charging facilities in expressway service areas in Beijing, Liaoning, Jilin, Shanghai, Zhejiang, Hunan and Xinjiang has reached 100%.

　　According to the data of China Electric Vehicle Charging Infrastructure Promotion Alliance, at present, the increment ratio of piles to vehicles is 1:2.5, and the construction of charging infrastructure can basically meet the rapid development of new energy vehicles. Experts say that highway charging piles are usually idle and not enough for holidays. To solve this "tidal" problem, we should not just consider the increment, but also improve the quality to ensure its economy.

　　In Liaoning, for new energy vehicle users, the local high-speed charging travel guide has been issued, so that drivers can check the layout of charging piles in advance, so as to better plan the charging line. At the same time, the local power department also accurately grasps the status of each charging pile, such as pile body, display and charging cable, through the digital platform, and problems can be solved in real time.
