Light equipment, heavy experience, high socialization and low threshold make minority projects enter the public’s field of vision and create new scenes for the in-depth development of national fitness. The industry generally believes that in recent years, the public’s enthusiasm for outdoor sports has become increasingly high, which has given the soil for the rapid development of minority projects: triggering community interaction through online sharing, promoting potential users to participate in offline experiences, and then stimulating more online sharing, thus forming a agglomeration effect and a positive cycle among youth groups.

At night, the football field in Beijing Laojuntang Park is brightly lit, and the teams of two flag football clubs are playing a friendly match. The attacking player hangs a colorful waist flag around his waist, and the defending player pulls out the opponent’s waist flag instead of a collision confrontation to stop the attack. Both sides come and go, both tactical and physical competition, but also the joy of "tearing famous brands" game.

Seeing the enthusiasm of everyone, Sun Mowen, a young man after 1995, was quite emotional. Since he initiated the establishment of a flag football club last winter, nearly a thousand people have participated in the activities in just a few months, with 4-5 activities every week, and the places are often robbed in 10 minutes.

This summer, after Frisbee became the first popular sport, flag football also accelerated its "rush" to the youth group. Light equipment, heavy experience, high socialization and low threshold make minority projects enter the public’s field of vision and create new scenes for the in-depth development of national fitness.

Bring social distance closer on the sports field.

In people’s impression, rugby is a fierce sport, with heavy protective gear and high-intensity physical requirements, which makes it difficult for ordinary people to participate. As a "simplified version" of football, the flag football continues its characteristics of tactical game and teamwork, and gets rid of the high requirements for equipment and venues. The low antagonism greatly reduces the threshold for participation. "The rules are relatively simple, and most novices can master it after two or three activities, and even directly participate in the competition." Sun Mowen said.

Sun Mowen initiated the establishment of the club with the original intention of "letting more people play with us". This sport was introduced to China as early as 2003, and it has been tepid until it entered the public’s field of vision this year. Strong social attributes are the key to quickly "bonding" fans. "Waist flag rugby requires timely communication and division of labor between teammates. The novice field organized by the club has 30 people at a time, and the activity lasts for two hours, so that teammates can have a basic understanding, especially to enhance team cohesion. " Sun Mowen said.

Relying on the community and clubs to meet the dual needs of finding fresh sports experience and offline socialization has become a unique starting point for project promotion. In the eyes of the industry, when participants find companions with the same lifestyle and form a strong sense of identity, they are more willing to continue to invest time and energy in this sport.

Jin Xin, a young man born in 1980s, is engaged in the financial industry in Shanghai. Last October, he joined a waist flag football club, which witnessed the rapid growth of the club’s membership doubling. "I met some like-minded partners in the flag football activity, and later I had a pleasant cooperation at work." Jin Xin said that the communication in the sports field is more pure, and the consistency of interests shortens the social distance.

According to the data, there are about 45 national flag rugby communities and societies, and there are about 150 community organizations and off-campus training institutions. Compared with traditional sports such as football and basketball, emerging sports with stronger sense of games and mixed teams of men and women can better meet the needs of youth groups, and even novices can quickly integrate into the team. As some people have commented, Frisbee and flag football have both sports value and emotional and social value.

Online promotion forms community interaction.

In April this year, Zhao Xinjia, a girl from Tianjin, first came into contact with flag football under the leadership of her friends. "There is no collision in this sport. Even if you can’t run fast or jump high, it doesn’t matter. You can use flexibility to run and attack." Now, she has become an active member of the club, playing several rounds every week.

Another reason why Zhao Xinjia is fascinated by flag football is online sharing. After each activity, she will post sports notes on social platforms and record her progress with photos and videos. "I will also read other people’s sports notes and exchange experiences with each other. Waist flag football pays attention to strategy and cooperation, and there is a lot of room for learning and advancement. "

Feeling the online sharing needs of participants, many clubs have introduced the follow-up business. When Sun Mowen organizes flag football activities, he always invites professional photographers to capture hundreds of photos on the spot, and then makes the materials into photo albums and videos for everyone to download. The wide spread of fans online is tantamount to natural advertisements. "There are many novices who are pushed through social platforms and attracted by photos of club activities to sign up." Sun Mowen said that this also promoted the club to build its own brand more carefully.

Emerging sports have a distinctive trend label, which is in line with the pursuit of fashion and personality of contemporary young people. The online platform where young users gather has therefore become the best carrier for "incubating" niche projects. When Xiaohongshu, a life social platform, was launched, the related search volume of "Frisbee" increased by about 24 times compared with the same period of last year, and the original content of "Waist Flag Rugby" also ushered in rapid growth after March this year.

People in the industry generally believe that in recent years, the public’s enthusiasm for outdoor sports has become more and more high, giving the minority projects a soil for rapid development. Combing this process, the great help of online promotion can be clearly seen: online sharing can trigger community interaction, promote potential users to participate in offline experience, and then stimulate more online sharing, thus forming a agglomeration effect and a positive cycle among youth groups.

Market expansion stimulates consumption potential

The popularity of minority sports has also opened up a blue ocean for the fitness market. Although this "small and beautiful" business has just taken the first step of exploration, many people have seen the consumption potential behind it.

Take part in the two-hour activity 60-80 yuan, rugby gloves 150-300 yuan, plus the mouthguard 100 yuan, which is the cost of Jin Xin’s participation in the flag football activity. "Ordinary fans can wear ordinary sportswear and sports shoes, and the lower consumption threshold is also the reason why novices are willing to try this sport." At the club level, organizing an activity includes booking venues, novice training, drinking water, photography and other expenses. "There are more and more people participating now, but our club has not raised the price. I hope that coaches and photographers with higher cost performance can enhance the sports experience and make them really fall in love with the flag football." Sun Mowen said.

Although at this stage, emerging sports have not yet spawned a mature business model and industrial chain, Jin Xin is optimistic about the consumption potential of the participating groups: "These fitness experts have commercial value, and full cultivation can tap many opportunities, such as event organization, sports tourism, and sports brand promotion." It is reported that some flag football clubs in Shanghai have begun to make profits.

Let the public participate in the normalization, let the senior fans specialize, and finally let the project be competitive, which is regarded as the key to the further development of emerging sports. Wang Xueli, director of Tsinghua University Sports Industry Development Research Center, said: "For sports participants, with venues and activities, the consumption of sporting goods and sports services will naturally increase."

To the delight of people in the industry, "Ultimate Frisbee" was selected as a fashion sports project in the "Compulsory Education Curriculum Scheme and Curriculum Standards (2022 Edition)" recently promulgated. Now, there is a mature middle school league in Shanghai. "Emerging sports entering the campus will bring benefits to equipment research and development, coach training, talent reserve and consumption habits. Especially teenagers, if they start playing a sport from an early age, they will probably keep playing. " Xue Zhixing, deputy secretary general of the National Frisbee Promotion Committee, said.

The Central Meteorological Observatory continued to issue a typhoon blue warning at 10: 00 on October 20.

  CCTV News:The Central Meteorological Observatory continued to issue a typhoon blue warning at 10: 00 on October 20:

  This year’s No.16 typhoon "Sanba" (tropical storm level) landed again at the coast of Suixi County, Guangdong Province around 9: 45 am today (20th). At the time of landing, the maximum wind force near the center was 8 (20m/s), and the lowest pressure in the center was 995 hectopascals. At 10 o’clock in the morning, its center is located in Suixi County, which is 21.1 degrees north latitude and 109.7 degrees east longitude. The maximum wind force near the center is 8 (20 m/s), and the lowest pressure in the center is 995 hectopascals.

  It is estimated that "Sanba" will move southwards at a speed of about 10 kilometers per hour, and approach the coastal area in the northwest of Hainan Island, and its intensity will gradually weaken.

  Gale forecast:From 14: 00 on the 20th to 14: 00 on the 21st, there will be 6-8 winds in the northwest of the South China Sea, Beibu Gulf, Qiongzhou Strait, the central and western coastal areas of Guangdong, the coastal areas of Guangxi, and the northern and western coastal areas of Hainan Island, with gusts of 9-10.

  Precipitation forecast:From 14: 00 on the 20th to 14: 00 on the 21st, there were heavy rains in parts of southern South China, among which there were heavy rains (100-240mm) in parts of southeastern Guangxi and southwestern Guangdong. Some of the above areas are accompanied by short-term heavy rainfall (the maximum hourly rainfall is 20-50 mm, and the local area can exceed 80 mm), and there are strong convective weather such as thunderstorms and strong winds.

  Defense guide:

  1. The government and relevant departments shall, in accordance with their duties, do a good job in typhoon prevention and emergency rescue.

  2. Water operations and passing ships in relevant waters should return to Hong Kong to take shelter from the wind, strengthen port facilities, and prevent ships from anchoring, grounding and collision.

  3. Stop large-scale indoor and outdoor gatherings and dangerous outdoor operations such as high altitude.

  4. Reinforce or dismantle structures that are easy to be blown by the wind. Personnel should not go out at will. They should stay in windproof and safe places as far as possible, so as to ensure that the elderly and children stay in the safest place at home, and the dangerous people will be transferred in time. When the typhoon center passes by, the wind will decrease or stay still for a period of time. Remember that the strong wind will suddenly blow and you should continue to stay in a safe place to avoid the wind.

  5. Relevant areas should pay attention to prevent flash floods and geological disasters that may be caused by heavy precipitation.

Interview | Deng Chao took the heart to respond, "China Table Tennis" is going to counterattack?


Special feature of 1905 film network
On February 17th, the schedule was adjusted several times.

(hereinafter referred to as "China Table Tennis") finally meet with you.

As of press time, the box office has exceeded 72 million.

# China Ping-Pong Box Office # Related topics are listed in Weibo Hot Search.

"’The movie looks good’ is no longer the standard for going to see a movie.

The sense of ritual is becoming more and more important.

Mystery is becoming more and more important. "

Some netizens feel that,

As we all know, the topic of China Ping Pong is selected.

There is no "mystery" to some extent.

Even though the film Douban scored 7.0,

Created the best reputation with the director’s career.

At present, there is still a lot of room for improvement at the box office.

"Some people say that we are a persuasion group.

I hope the audience with this idea will come to see this movie. "

In the face of constant bad reviews of past works and even word-of-mouth overdraft,

Deng Chao responded on the occasion of the release.

Compared with previous creations,

He seems to be more attentive this time.

Some time ago,

"Deng Yu Group" took actor Liang Chao as a guest in China Film Report.

Dialogue movie channel host Roman, intern reporter He Junlin,

Talk about the film’s creation over a thousand days.

When my father was young, he was the champion of table tennis doubles in Chang ‘an County, Shaanxi Province.

Influenced by it,

Yu Baimei is also a big sports fan.

I have been looking forward to making an exciting sports movie.

So he directed China Ping-Pong,

It has also become his "dream of dreams."

The film tells the story that China men’s table tennis fell to the bottom in the 1990s.

The new coaching team has transformed them in all directions.

Help Guoping make a comeback at the 1995 Tianjin World Table Tennis Championships.

"An underrated coach,

A group of underdogs.

At the lowest point, the Jedi fought back. "

Deng Chao said frankly,

He can fully understand the characters in China Ping-Pong.

Because he and Yu Baimei have experienced failures,

I have been criticized by everyone and ridiculed by online groups.

How hard it is for the underdog to get things done,

He is very clear.

The story of Ping-pong’s counterattack against the Jedi made the two directors feel the same.

They want to make China Ping-Pong into their own style.

Deng Chao plays the head coach "Dai Minjia" in the movie.

He is not skilled.

Shi Zhihao and Li Nan, famous table tennis coaches, were invited to become "military advisers".

Practicing table tennis skills from scratch.

Although I am ready to "suffer".

But wait until the coach says, "Come on!"

He "abused" him for the first time in class for almost two hours.

This also made Deng Chao shout "I almost fainted!"

In particular, the character "Dai Minjia" is a "left-handed".

He is even more "headache" for this.

So make sure you get used to using your left hand?

The solution that Deng Chao came up with was,

Whether you eat or play ball,

Let colleagues around you keep a close eye on themselves,

Once he is found to be using his right hand,

You need to fine him.

The film took more than 1000 days from preparation to release.

The crew has always had 18 professional table tennis consultants "sitting in the array".

Under the guidance of all the masters,

The "dark war" between Yu Dao and Deng Dao can always offer jokes for everyone.

Liang Chao, who also plays the table tennis coach in the film, broke the news.

of course,

Deng Chao and the pair of "stooges" are indispensable sources of jokes for the crew.

In the scene where Deng Chao was kicked out of bed by Sun Li,

I only took it once and it passed.

Yu Baimei joked that,

This somewhat reflects the life experience of the couple.

I am just their "recorder".

"Sun Li is the best head of the family."

Speaking of his wife’s constant companionship and encouragement,

Deng Chao said emotionally,

Over the years,

I am especially grateful to Sun Li for her silent contribution.

"I think we made a good movie,

If measured by life,

It’s graduated. "

Assembled the painstaking efforts and efforts of the crew,

Deng Chao finally could not help but sigh,

I hope the film is dedicated to everyone who is not optimistic.

How to treat the "usefulness" and "uselessness" of culture

Original title: How to treat the "usefulness" and "uselessness" of culture?

Zhongqingbao Zhongqingwang reporter Xia Wei

For drinking tea, it is obvious that ordinary white porcelain bowls can meet the demand, but why do we prefer porcelain tea set with fine workmanship? When writing, the arm rest is used to prevent the arm from being stained with ink. Obviously, as long as it has the function of putting the arm, why do we pay attention to its material and the carving on it? When we are moved by the beautiful artistic conception of an ancient poem, when we are fascinated by the exquisiteness and elegance of a handicraft, what do we get from it? What can those humanistic details and artistic values bring to our lives? Or, is culture "useful" or "useless" to our life?

The "uselessness" of culture is also "great use"

In the dialogue session hosted by Bai Yansong at the 15th Cultural China Forum, Pan Lusheng, chairman of China Folk Writers Association, pointed out that "useful" means "practical" and "useless" means aesthetic "useless". Material and spiritual use and life use are both useful and practical, while useless is also useful and even useful.

Pan Lusheng introduced that in Lin ‘an City in the Southern Song Dynasty, the palace culture, the literati culture and the street culture were integrated, which formed the idea of "craft for practical use", and also created a life style of unity of practicality and aesthetics in the Southern Song Dynasty. During this period, the weaving technology was superb, and the fabrics made were dense and light as cicada’s wings. Not only were there various types of yarn, Luo, Qi and Ling, but the silk reeling and embroidery techniques were also superb. The gardens in the Southern Song Dynasty are like three-dimensional landscape paintings with pavilions and winding paths, which contain the spiritual complex and aesthetic artistic conception of literati. From the clay figurines of children in the Song Dynasty in Zhenjiang Museum, to the Children’s Plays in the City in Taipei Palace Museum, from the white porcelain children’s pillows in Dingyao in the Palace Museum, to Song Jin’s Paintings of the Hundred Immortals in Cleveland Art Museum in the United States, all of them reflect the aesthetics and interest of life in which humanities and art are combined with street life.

In contrast, in today’s fast-paced diet and fragmented culture, modern people no longer seem to have an attitude of attaching importance to life aesthetics, and traditional crafts no longer pursue use value. In this context, should we learn from the ancients and return to the "elegant life" way of the Southern Song Dynasty?

"The handicraft tradition of the Southern Song Dynasty is historical and contemporary, which runs through the traditional Chinese aesthetic spirit, lifestyle and cultural taste." Pan Lusheng said. Therefore, he proposed to develop a new economy of Song rhyme culture, take people’s life needs as the guide, enhance cultural life experience, and study how elegant lifestyle can be integrated into today’s life, so that people can gain a sense of cultural identity.

Pan Lusheng believes that, on the one hand, by reviving traditional crafts, we can explore how to better inherit and utilize traditional craft and cultural resources at present, inject the culture of Xixiang into education and cultural communication, and serve people’s spiritual and cultural life. On the other hand, through the development of cultural industry with cross-industry barriers, traditional craft culture can be transformed into the resources of contemporary Song Yun cultural industry, creating higher economic value, thus better serving people’s material and cultural needs.

"Cultural pension" is worth looking forward to.

On the aesthetic level of life, the "usefulness" and "uselessness" of culture may be a philosophical proposition, but in the medical field, the "usefulness" of culture is indispensable. According to Zheng Xiaoying, academician of the Academy of Sciences of developing countries and director of the Peking University Population Research Institute, culture is even more "useful" than science and technology.

Zheng Xiaoying said, "Everyone’s ultimate wish is to grow old healthily and say goodbye to the world happily. This is by no means a problem that can be solved by relying solely on science and technology or medical means, but a realm that must be achieved through the combination of culture, art and technology. In this sense, the infiltration of culture is more important than the development of science and technology. "Zheng Xiaoying believes that" medical art education should be integrated into medical education so that every doctor can accumulate deeper artistic accomplishment and cultural heritage. "

Zheng Xiaoying pointed out that cultural blessing is also needed to deal with the problem of population aging. She introduced that with the intensification of the aging process, the life expectancy of China’s population is also increasing rapidly. However, most of the increased life expectancy is unhealthy, that is, life expectancy with disabilities. Among the disabled people in China, 53% are elderly people. To solve the problems of these elderly disabled people, we need the support of science and technology, but more importantly, we need the support of culture. "Let them be happy and enjoy the benefits brought about by the reform and opening up to the maximum. This is not a problem that can be solved by a simple assistive device."

At the same time, Zheng Xiaoying emphasized the concept of "cultural support for the aged", which is a way to support the aged on the premise that the material needs of the elderly are basically guaranteed, on the basis of meeting spiritual needs, on the basis of communicating emotions, exchanging ideas and having a healthy body and mind, and on the purpose of publicizing individuality, advocating independence and enjoying the spirit of happiness and pleasure. "Cultural pension meets the spiritual needs of the elderly. For the elderly without children, this pension model is particularly important." Zheng Xiaoying said.

How to realize the mutual integration of science and technology and humanities

Undoubtedly, the integration of culture, art and technology can make people’s lives better. So, as an individual, how should we start from ourselves and realize the integration of technology and humanities? This is also a question that Wang Yuming, an academician of China Academy of Engineering and an expert in fluid sealing engineering technology, is often asked.

Wang Yuming laughed and called himself a "science man". "However, although my main business is mechanical engineering, I am not" mechanical "culturally. He is a student of Mr. Ye Jiaying, a consultant of the Chinese Poetry Society, the director of the Poetry Working Committee of colleges and universities, and the president of the Tsinghua University Lotus Pond Poetry Society. It can be said that he is a person who perfectly balances "poetry and distance".

When answering the question "how to realize the mutual integration of science and technology and humanities", Wang Yuming believes that in terms of values, science and technology and humanities and arts are both pursuing truth, goodness and beauty, and they are essentially interlinked; In the mode of thinking, both of them need logical thinking and inspiration epiphany thinking, which can promote each other. The same is true of many masters of science and technology (such as Einstein, Yang Zhenning, Qiu Chengtong, Gu Yuxiu, Qian Xuesen, etc.). However, the most important thing is to have a "pure heart" in both scientific research and literary creation.

On the "Use" of China Culture from the Outside

The Chinese culture has a long history, and the "useful" culture not only created the fashion life of the ancients, but also injected spiritual strength into solving modern social problems, and also brought about an impact on the civilized development of neighboring countries.

In the dialogue session, Cheng Yonghua, former Japanese ambassador extraordinary and plenipotentiary to People’s Republic of China (PRC) and executive vice president of China-Japan Friendship Association, introduced the "use" of Japanese culture to neighboring countries. He said that China’s culture had a profound influence on the Korean Peninsula, Viet Nam and Japan. Take Japan as an example. The Sui, Tang and Song Dynasties were the historical peaks of Sino-Japanese cultural exchanges. During this period, ancient Japan sent 19 groups of envoys to China to study, with a maximum of 600 people at a time. In addition to sending envoys, a large number of international students also came to China from ancient Japan. Many of them stayed for many years, and some even stayed in China to work as officials in Chang ‘an until they died and were buried in Chang ‘an. In 645 AD, the ancient Japanese carried out the "Dahua Innovation" movement, abolished the monopoly regime system in big noble, and established an ancient centralized state with reference to the rules and regulations of the Tang Dynasty in China. During the Song Dynasty, more and more Japanese people came to China to study. Jian Zhen, a monk in the Tang Dynasty, traveled eastward to preach the precepts to Japan and was honored as the ancestor of Japanese Buddhist legalists. The Tang Zhaoti Temple complex built by him and his disciples in Nara, Japan, embodies the architectural characteristics of the Tang Dynasty and is the largest and most beautiful building in Japan’s existing Tianping era. Japanese characters are also born out of Chinese characters. At first, there were only languages but no characters in Japan. In asuka period, Buddhist classics introduced into Japan along with Buddhism made Chinese characters penetrate into Japanese life. The first Chinese characters were used by ancient Japanese as phonography, but they were troublesome in the process of use, so heian period invented katakana and hiragana with reference to the radicals and cursive scripts of Chinese characters. In addition, the present Japanese court music-gagaku,It is also music from the Tang Dynasty in China.

Cheng Yonghua said that Sino-Japanese exchanges have a history of 2,000 years. Today, Japanese young people are still attracted by China’s rapid economic development and technological innovation, and feel that "they should go to China to see more and communicate more".

Whether it is "practical" or "useless", the China culture of the same strain needs and deserves to be passed down and carried forward by contemporary people. As Pan Lusheng said, culture is a nation’s overall lifestyle and value system. If the ancients’ fashion is integrated into contemporary life, we may be able to create a pioneer culture with temperature, connotation and taste in the new era.

Those who have a positive infection in Shanghai today have three emergency measures to implement three aspects

At 5:00 pm on June 26, the Shanghai Municipal Government News Office organized a press conference of the 218th press conference of Shanghai New Crown Pneumonia’s epidemic prevention and control work. Zhao Dandan, deputy director of the Municipal Health and Health Commission, Lai Xiaoyi, a second -level inspector of the Municipal Commerce Commission, Long Wanli, deputy head of Jing’an District, Zhang Yefang, deputy head of Fengxian District, and Sun Xiaodong, deputy director of the Municipal Centers for Disease Control and Prevention, attended the relevant situation and answered questions from reporters. Essence Municipal Government spokesman Yin Xin presided over a press conference.

Some reporters asked, how many medium -risk areas are there at present in Shanghai? After a lapse of a few days, there is a sporadic infection in Shanghai. Can you do some analysis for the current epidemic situation?

Zhao Dandan said that as of now, there are 13 areas of risks in the city in the city, involving Xuhui, Baoshan, Songjiang, Yangpu, Hongkou, Putuo, Jing’an, Minhang, Fengxian, etc. Risk -regional. In this way, since 0:00 on June 27, there are 12 central risk areas left in Shanghai.

After 5 consecutive days in Shanghai, there were no social positive infections, and there was a sporadic positive infection today. It should be soberly realized that the transmission of Omikon’s mutation is fast and hidden. As the current flow of personnel gradually increases, the risk of rebound in the Shanghai epidemic still exists. Therefore, we must adhere to the total policy of "dynamic clearing zero", strictly implement the "four -party responsibility", and focus on implementing three aspects of emergency response measures:

First, in terms of command systems, the city and district -level command systems have always maintained a stress state. After discovering positive infections, they must respond as soon as possible, and respond to emergency response in a timely manner to block the spread of epidemic as soon as possible.

Second, in terms of discovery mechanisms, constantly improved the convenient and sensitive discovery mechanism, established and improved the comprehensive monitoring system of "nucleic acid+antigen", "place code+digital sentry", "hot kidnapper+pharmacy" Early discovery, early report, early disposal.

Third, in terms of the synergy mechanism, maintaining the collaboration between the public security, public health, industrial information, and big data centers and districts. Once those who are positive are found, they will immediately implement the "2+4+24" requirements, that is, the flow team is 2 hours. Arrive at the scene, complete the core information of the flow tone within 4 hours, and initially check the basic situation and complete the flow report within 24 hours.

Here, the friends of the general public are invited to continue to adhere to the "three -piece set" and "five more", and to do the following:

The first is to keep in mind the "two musts", that is, the code must be scanned, and nucleic acid detection must be performed as required.

The second is that in the face of the influence of the epidemic prevention personnel, we should fulfill the responsibility of epidemic prevention and truthfully inform the event trajectory and other information. We will protect your privacy.

Third, once suspicious symptoms such as fever occur, be sure to do personal protection and go to the nearest clinics in time.
