Panoramic view of the gymnasium from the north and south sides

　　The 29th Olympic Games official website December 3rd Recently, a beautiful "China Ridge" building was completed on the campus of Peking University, west of Zhongguancun North Street and south of Pacific Tower, which is the first table tennis stadium in the Olympic history and the world.

　　"Ping-Pong Diplomacy" ball rotates the earth, and "China fever" and "Ping-Pong fever" blow up in the United States.

　　Speaking of table tennis, Chinese people are no strangers to it.

　　On January 29th, 1971, Premier Zhou Enlai met with the leaders of the State Sports Commission (the predecessor of the State Sports General Administration) and gave important instructions on China’s participation in the 31st World Table Tennis Championships. At that time, Japanese friends, represented by Fujikura, hoped that China could re-participate in the World Table Tennis Championships after a lapse of four years, while China was in the turbulent era of the Cultural Revolution. Whether to participate in the World Table Tennis Championships or not could only be decided by the country’s top leaders. Under the international situation at that time, Mao Zedong and Zhou Enlai hoped to open up the diplomatic situation and decided to participate in the 31st World Table Tennis Championships for China, so they performed a wonderful swan song in the history of international relations.

　　As a result, the small table tennis not only made China athletes reappear in the world sports four years later, but also promoted the improvement of the relationship between China and the United States as a medium, which fundamentally changed the world pattern during the Cold War-the ball turned the earth.

　　On April 18th, 1972, US President Nixon received the visiting China table tennis team at the White House.

　　China’s table tennis team’s visit to the United States is a return visit to the United States in 1971. The host gave China guests unprecedented high-standard treatment: President Nixon met all the members at the White House; China team was invited to the United Nations Headquarters for competitions and performances; "China fever" and "table tennis fever" have arisen among the American people. From the 31st World Table Tennis Championships, "Ping Pong Diplomacy" reached its climax.

　　Here is a little story: an American athlete accidentally boarded a van specially arranged by the organizing committee of the World Table Tennis Championships for the China team (such vehicles have the same appearance, so they got on the wrong bus), and got a gift from Zhuang Zedong. The scene where they appeared together in the car door was hyped by sensitive foreign journalists, and a series of subsequent events began.

Viewing the roof of the gymnasium from the interior

　　The Olympic table tennis tournament has been held for five sessions, and each session has been "cohabited in one room" with other events.

　　When it comes to table tennis, everyone familiar with the Olympic Games will not be unfamiliar with it.

　　On June 23rd, 1894, when French Duke Pierre de Coubertin and 79 representatives from 12 countries decided to establish the International Olympic Committee (IOC) to create the modern Olympic movement, this feat was once the object of ridicule.

　　From April 6 to 15, 1896, the first modern Olympic Games, after experiencing many difficulties, rekindled the Olympic flame in Greece, the birthplace of the ancient Olympic Games. A total of 311 male athletes from host Greece and Australia, Britain, Hungary, Germany, the United States, Sweden and other 13 countries participated in track and field, swimming, weightlifting, shooting, cycling, tennis, gymnastics, fencing, greco-Roman wrestling and so on.

　　It was this Olympic Games that ushered in a new era of modern Olympic movement.

　　But it was not until 1988 that table tennis first appeared as a formal event in the 24th Olympic Games in Seoul, Korea. As the capital of South Korea, Seoul is a modern city with obvious contrast, and many historical and cultural heritages have been preserved. The towering skyscrapers and antique traditional tile eaves set each other off.

　　Before the construction of venues and facilities for the 10th Asian Games began, Seoul had been selected as the host city for the 24th Olympic Games. Therefore, in the planning stage of the venue construction of the Asian Games, the issue of how to make full use of its facilities for the Olympic Games after the Asian Games in Seoul was considered to avoid repeated construction.

　　In December, 1986, the Seoul Organizing Committee for the Olympic Games determined the overall plan for the construction of Olympic venues, including 34 competition venues and 72 training venues. According to the plan, 21 existing venues and facilities will be used as competition venues for the Olympic Games, and 13 others will be newly built. The 72 training venues are also converted from existing facilities.

　　Seoul Comprehensive Sports Center is located in the sericulture area in the southeast of Seoul, about 13 kilometers away from the city center, covering an area of 591,000 square meters. It includes five international standard stadiums: Olympic Stadium, Sericulture Gymnasium, Sericulture Swimming Pool, Sericulture Student Sports Ground and Sericulture Baseball Field.

　　The first Olympic table tennis competition was held in one of them, the Silkworm Room Stadium. The Silkworm Room Stadium is divided into the ground floor and the ground floor, with a building area of 25,800 square meters, which can accommodate 20,000 spectators. In addition to table tennis, Olympic basketball, volleyball, handball, boxing and wrestling are also held here.

　　Since the Seoul Olympic Games in 1988, although table tennis competitions have been held for five consecutive Olympic Games, just like the Seoul Olympic Games, the organizers of the other four Olympic Games have arranged table tennis competitions and other "brother" events in the same venue.

Viewing Peking University Gymnasium from the Northeast Corner

　　The "China Ridge", the first table tennis hall completed and flying, entered the century-old Olympic building.

　　Now, the table tennis venue of the 2008 Beijing Olympic Games-Peking University Gymnasium has been completed. This is not only the first Olympic table tennis hall in Olympic history, but also the first dedicated table tennis hall in the world.

　　The project has a building area of 26,900 square meters, with a length of 122.6 meters from north to south and a width of 87.7 meters from east to west. It consists of a table tennis hall and a swimming pool. The table tennis court is located on the first floor, with a length of 47 meters and a width of 39.5 meters. Eight table tennis tables can be arranged for the game. After the movable seat is put in, the stadium is transformed into a length of 27 meters and a width of 20 meters, and two table tennis tables can be arranged for the final. A total of 7,557 fixed and movable seats can be provided during the competition.

　　From December 13th to 19th, 2007, the final of ITTF Professional Tour 2007 will be held here. From August 8th to 20th, 2008, the table tennis preliminaries of the Olympic Games will be held, and from September 9th to 17th, 2008, the table tennis preliminaries of the Paralympic Games will also be held here.

　　After the Olympic Games, the Gymnasium of Peking University will be transformed into Peking University Comprehensive Gymnasium, which can hold table tennis, handball, basketball, badminton, volleyball, indoor football, gymnastics competitions and professional training, students going to physical education class, gatherings and cultural performances.

　　Flying "China Ridge" Dynamic Table Tennis Modeling

　　Standing on the flat ground and looking up at Peking University Gymnasium, the traditional shape "China Ridge" stretches its wings, which is inherited from the century-old Yanyuan building. The facade is a concrete slab standing in a frame shape, with elegant and generous design; If you look down, you will find another world on the roof: the transparent sphere protruding from the center is matched with two rotating roofs, and the dynamic table tennis is ready to come out.

　　The roof of Peking University Gymnasium is a chord-supported reticulated shell steel structure with a span of 64 meters. The roof structure consists of seven parts: lower rigid ring, central rigid ring, central spherical shell, radiation truss, horizontal and vertical support system, cornice support system and cable support system. The roof is hyperboloid, and the structural system is relatively complicated in all Olympic venues.

　　The roof of Peking University Gymnasium is called "China Ridge" because it uses two spiral curved surfaces on the metal roof as the shape, which is in the same ridge with the nation, Peking University, the national ball and the building. The glass ball in the center and the openable window on the roof ensure indoor natural lighting and good natural ventilation, which can meet the needs of school training.

　　The speed, strength and rotation required by table tennis are all fully interpreted in the dynamic table tennis modeling that comes to the fore. The architectural design of the gymnasium is named "China Ridge", which means the ridge of the nation, the ridge of Peking University, the ridge of the national ball and the ridge of the building.

　　The concept of high-tech Olympic Games is integrated into the traditional "China Ridge"

　　Peking University Gymnasium is called "Olympic stadium with high technology content" by architects, and the lighting control of the main stadium, warm-up field and swimming pool of Peking University Table Tennis Hall adopts distributed intelligent lighting. The indoor integrated automation system of power transformation and distribution will be connected with the BA system of gymnasium, and the main line switches and transformers can realize long-distance real-time telemetry, remote communication, remote adjustment and remote control.

　　The steel structure consists of seven parts, such as prestressed cable support system, horizontal and vertical support system, which hold up the "table tennis" with pulling and pulling. For this special steel structure system, there are many technical problems in welding seam, aerial docking, prestressed tensioning of truss steel cables and so on. After the previous demonstration and experiment, the safe and efficient high-altitude fragmentation technology was adopted in the construction process, and the construction project was monitored, which provided a guarantee for the construction safety and the construction of the main structure by using scientific data.

　　The heating of about 3,000 square meters of media and logistics rooms on the first floor of the gymnasium will be provided by ground heat pump. The system is equipped with two sets of ground heat source heat pump systems through vertical underground pipes arranged in parallel, and uses soil energy to provide heating and cooling for buildings, with a cooling capacity of 31OKW and a heating capacity of 493KW.

　　Solar photothermal technology can also provide sufficient heat for the swimming pool in the museum. The heat collection area of the system can reach 300 square meters, saving 240,000 KW of electricity every year.

　　Siphon drainage, lighting, intelligent control system … You can see the flash of science and technology in every detail in the gymnasium.

　　Protect antique "Zhibeizi Garden" and ancient trees

　　Peking University Gymnasium is located on the east side of the campus, avoiding Zhibeizi Garden and ancient trees, and the north and south sides are evacuation sites for spectators. The overall layout of the building retreats to the east, forming a continuous landscape of the western Zhibeizi Garden, ancient trees and newly-built courtyards, and providing users with suitable external activity space to guide fresh and different experiences with diverse spatial feelings and landscape changes. Thus, it is in harmony with the quiet and elegant architectural garden style formed by the profound historical deposition of Peking University.

　　At the beginning of the construction, there was a group of quadrangle protection buildings on the west side of the stadium-Zhibeizi Garden, which was built in Jiaqing period of Qing Dynasty. On the south side of the garden, there were six listed and protected ancient trees (Pinus massoniana, Pinus bungeana, Platycladus orientalis, Sophora japonica, etc.) with different tree species and good posture. In order to protect the cultural relics, the overall layout of the stadium retreated to the east, avoiding the cultural relics and ancient trees, and the pre-buried pipelines encountered in the underground "moved" with the venue, thus forming a continuous landscape of Zhibeizi Garden, ancient trees and new courtyards in the west. As a result, the north and south sides of the gymnasium are set up as audience evacuation sites, which are in harmony with the quiet and elegant architectural garden style formed by the historical deposition of Peking University for more than 370 years.

　　Displacement ventilation of auditorium

　　Peking University Gymnasium is the first specialized gymnasium specially built for table tennis competition in the world. The background in the table tennis competition venue is as dark as possible to ensure that athletes are not affected by the environment during the competition; The wind speed of ventilation and air conditioning should not exceed 0.2 m/s, and there should be no glare in lighting, which was first reflected in Peking University Gymnasium.

　　The gymnasium of Peking University has a beautiful and unique architectural shape, which is unique against the Zhibeizi Garden and ancient trees on the west side. The glass spherical shell and two rotating roofs in the center of the roof look like spinning table tennis from the air, which implies the use function of Peking University Gymnasium for Olympic Games. The roof of Peking University Gymnasium is made of metal, with two layers of waterproof and thermal insulation, and rain-proof and noise-reducing treatment. The ground of the stadium is a double-deck overhead sports floor, specially imported from the United States, and the wall is a wooden sound-absorbing board, which has good sound effect.

　　The auditorium of the gymnasium adopts displacement ventilation mode, and the wind speed at the tuyere is less than 0.5 m/s, which forms the effect of displacement ventilation at the seat, and reduces the cold and heat load of air conditioning in the auditorium as much as possible under the condition of satisfying the thermal comfort of the auditorium. The main table tennis court area adopts the air conditioning system with side-to-side feedback on both sides of the court, and the wind speed of the air supply outlet is 3 m/s, which meets the requirement that the air conditioning wind speed in the middle area of the court is less than 0.2 m/s and ensures the temperature and humidity requirements in the court area.

　　In August, 2008, when the lilacs in Yanyuan once again reveal their fragrance, the China Ridge of Peking University Gymnasium will usher in the centennial Olympic event-Olympic table tennis match. The gymnasium will not only provide excellent competition environment for athletes and other officials, but also set off the "China fever" and "table tennis fever" again.

1. Swimming can shape muscle lines and enhance muscle strength.

　　People can strengthen their muscles by swimming. Running can improve the strength of people’s legs, while swimming needs the coordinated efforts of muscles in all parts of the body, so the muscles of the whole body can be exercised. Legs are pushed backwards, arms are pulled, back is stretched and contracted, and abdomen is tightened to increase leg strength and maintain hip stability. These basic swimming actions make every muscle in the whole body HIGH, which not only enhances the strength, but also avoids the effects of muscle asymmetry that may be caused by equipment movement.

2, swimming can improve bone.

　　Once upon a time, many people scoffed at the idea that swimming can improve bones. After all, it seems that only weight exercises can achieve this goal. However, a study published in the journal of Applied Physiology supports this view. Because there are some moral controversies about bone examination directly on human body, researchers take mice as research objects and divide them into three groups: running group, swimming group and control group (no exercise). Research shows that running can improve the bone density best, and compared with the control group, the swimming group does better in both the bone density and the weight of thigh bone. It can be seen that if you want healthier bones, swim!

3. Swimming can improve the flexibility of the body.

　　Swimming requires people to stretch, curl up, turn around, paddle in the water, etc., and their feet act as fins to generate forward propulsion by pedaling. In the process of paddling, repeated stretching movements can help improve the flexibility and flexibility of the body, so office workers who often sit in offices and elderly people with joint diseases may wish to try swimming.

4. Swimming can reduce the risk of inflammation.

　　As we all know, swimming helps to enhance myocardial function and improve cardiovascular health, and related research further confirms that aerobic exercise such as swimming can help reduce the risk of inflammation, thus preventing diseases such as cardiac atherosclerosis caused by it. In addition, reducing the risk of inflammation in the whole system can also alleviate the deterioration of many other diseases, which has many benefits.

5. Swimming can help burn fat and lose weight.

　　Everyone knows that swimming can lose weight, but do you know that swimming can lose weight as much as running on a treadmill, and swimming can lose weight even more than running if you choose the right swimming posture and intensity? Take swimming for 10 minutes as an example, breaststroke can burn 60 calories, backstroke can burn 80 calories, freestyle can burn 100 calories, and butterfly can burn 150 calories. In contrast, running for 10 minutes can only consume 100 calories. You can know which is better or worse at a glance.

6. Swimming can relieve exercise-induced asthma.

　　There is nothing sadder than breathing difficulties during exercise! Compared with exercising in a gym with dry air or outdoors full of pollen, people can breathe moist air and improve their respiratory function when swimming. Studies have confirmed that swimming can not only relieve the symptoms of asthma, but also fundamentally improve the health of the lungs. The most typical example is Park Tae hwan, a famous Korean swimmer. He suffered from asthma when he was a child, and then his parents asked him to practice swimming to help relieve the symptoms. As a result, asthma not only disappeared, but also became an Olympic champion. It’s killing two birds with one stone!

Swimming can help relieve stress and depression.

　　Endorphin is a kind of feel-good hormone, which can improve people’s mood, while swimming can effectively stimulate the secretion of endorphins and help people relieve the pressure of daily work and life; In addition, swimming can make people fully relax their bodies just like yoga. If it is combined with regular deep breathing, the effect will be better. At the same time, swimming can calm people down, eliminate external interference and become more focused, which naturally reduces people’s tension and depression. Related studies have confirmed that swimming can also help restore brain function damaged by stress through a process called hippocampal nerve regeneration. So, if you feel out of shape one day, you might as well put on your swimsuit and jump into the pool to release your emotions!

8. Swimming in seawater can improve skin quality.

　　For beautiful women and handsome men who want to beautify their skin, it is a good choice to swim in the sea in summer, because swimming in the sea often is good for the skin, which not only helps to moisturize the skin, but also helps to detoxify the skin and promote the growth of new skin cells. When you are enjoying the carefree swimming, you will gradually find that your skin is getting better and better. There is no such good thing in the world!

9. Swimming can make people smart.

　　Yes, exercise can improve people’s mental state, but can swimming really make people smart? Researchers from Australia studied a group of children who took part in swimming training courses, and took another group of children who did not learn swimming as the control group. The results show that children who often swim are faster and better than the control group in mastering language, learning to ride a bike, building self-confidence and physical development. In addition, because swimming needs to calculate the swimming distance repeatedly, people who swim frequently also perform better in arithmetic.

10. Swimming can prolong life

　　Everyone knows that exercise can improve health and prolong life, but research further confirms that swimming is the best in these two aspects. Researchers at the University of Southern California have followed 40,547 men aged 20-90 for 32 years. The results show that the mortality rate of men with swimming habits is nearly half lower than that of men who run, walk or don’t exercise often. It can be seen that swimming is definitely a good prescription for longevity.

Extended reading: four correct swimming postures

"The elders who seek wood must consolidate their roots; Those who want to flow far away must dig their fountains. " Education has always been a century-long plan, and it is its glorious mission and fundamental task to cultivate people and keep innovation.

Nie Mao, a professor and doctoral supervisor at the School of Humanities, Central South University, has many titles: writer, poet and literary critic, but what he values most is the heavy title of teacher. At the beginning of December, he said in an interview: "The essence of education is that a tree shakes another tree, a cloud pushes another cloud, and one soul calls another soul."

Nie Mao was never satisfied with his temporary success. He not only encouraged himself with "the running posture is closest to the goal", but also carefully trained students and used his own educational philosophy to make successive students become adults. He devoted himself to his studies and set an example for students with his unswerving academic pursuit and profound academic support. With all his energy and painstaking efforts, he tried to practice what Mr. Da should do and feel in the new era of the unity of "Confucian classics" and "human teachers".

Be a guide in the process of students’ growth by osmosis and example.

The teaching work in Nie Mao is very heavy. There are 16 doctoral students and postdoctoral disciples, 13 master students and many undergraduates. He has his own unique views on teaching activities.

He believes that teaching and educating people is a "conscience work", and teaching his knowledge and experience to students should be based on conscience and worthy of the trust of students and schools. In his view, knowledge can be divided into "common sense" and "knowledge". "Common sense" can be understood as knowledge in books, which can be acquired through self-study; And "knowledge" is life experience and experience, which is wisdom left behind after years of baptism and precipitation and not found in books. As a teacher, we should not only impart "common sense", but also tell students about our own "knowledge" and use our own life experiences to help students broaden their horizons and avoid detours.

"After the night, every flower will be in full bloom." This is Nie Mao’s earnest warning.

He often leads students out of school and into the society, so that what they have learned can be applied in practice. "I also came from my student days. As an educator who has worked in Central South University for almost 20 years, I understand the needs of students. I have worked in the media industry, and I can do my best to help students, create opportunities for them to practice and seek jobs, be a paving stone for students, and guide them to grow up healthily. This is the duty and responsibility of a teacher. " Nie Mao said sincerely.

He once offered the course "New Media Research" for graduate students. He used his social resources and rich media experience to design a series of practical assignments with strong maneuverability, guiding students to stand on the society and combining professional knowledge with promoting the feelings of home and country and social positive energy in a "grounded way". Not only did the students complete the practical course results, but their experiences were also reported by the media, which caused a good social response.

Pursue university questions, be willing to sit on the bench and be a pioneer on the academic road.

In the field of academic research, Nie Mao’s research results are quite fruitful. In 2018, he launched the 7-volume, 3-million-word "China Experience and Literature Study on the Development of Xiang Army" at one time, and in 2021, he published the 5-volume, 1.7-million-word "Interdisciplinary Study on Urban Culture in the 21st Century" at one time.

Among them, the book series "Research on China’s Experience and the Development of Xiang Army" condensed his accumulation and contribution for more than 30 years. He began to engage in literary creation in the 1980s, witnessed the development of the Xiang army of literature and was deeply influenced by it. Then he kept reading related literary works and wrote a series of critical articles for Hunan writers, and his efforts day after day finally paid off. The English version of his academic monograph "Literary Expression of China’s Experience" was also published by Peter Lang, an internationally renowned publishing institution, as the final result of the foreign translation project of the National Social Science Fund.

In this regard, Nie Mao said that his overseas study experience has benefited him a lot. He not only learned a lot of knowledge during his doctoral studies, but also had an international vision and was able to do solid basic research on the shoulders of academic giants. At the same time, he studied classical literature for his master’s degree and cultural communication for his doctor’s degree. He also worked as a farmer, a doctor (examiner) and a reporter and editor in a news unit. His rich academic background made him form an interdisciplinary way of thinking and devoted himself to pursuing interdisciplinary "university questions".

He once said to his students, "Work like a ox and live like a camel." It is intended to encourage students to do a good job in a down-to-earth and steady manner, to have perseverance, to endure a difficult environment, and to "turn endurance into enjoyment".

In the interview, Nie Mao also repeatedly said: Everyone has only 24 hours a day, and he won’t give you one more minute and give another one less. How to make full use of these 24 hours is learned. "People see that I have written so many works in addition to teaching and scientific research, but few people know the hardships and efforts behind it. It is no exaggeration to say that every honor has a responsibility to bless, every achievement is watered by sweat, and no one’s success is easy. "

Keep writing, keep creating, and be the disseminator of advanced thought and culture.

In 2019, Nie Mao launched the long poem Hero of the Republic. The poem expresses his infinite memory of Yang Kaihui, Xiang Jingyu, Cai Hesen and other revolutionary heroes, as well as his feelings about the vicissitudes of the country. This is his gift to the 70th anniversary of the founding of New China, and it is also the crystallization of his painstaking efforts for more than 30 years.

"Hero of the Republic" has also been made into 20 audio and video issues, which are serialized in the learning power and the party building network; In the second half of 2019, the relevant departments of the province successively organized three large-scale poetry recitals of "Heroes of the Republic", which were held in Wangchengrong Media Center, Changsha Experimental Theater and the Auditorium of Central South University. More than 20 well-known reciters, performing artists and more than 1,000 students from universities, middle schools and primary schools in the province participated in the performance, and the online video was broadcast live simultaneously. Looking at the passionate performances of the primary, middle and primary school students on the stage, Nie Mao said with tears in his eyes: "We should pass on the story of the hero of the Republic in the form of poetry, so that the young people at present can understand the hero, approach the hero and draw the strength of spirit and belief from the hero."

The Hero of the Republic has been adapted into audio and video works, and at the same time, it has also released the "Children’s Edition" and "Song of Heroes" to spread the heroic culture in a way closer to minors, so that children can receive the edification and nourishment of excellent culture.

On this basis, Nie Mao led his scientific research team to publish a series of ideological and political papers, such as "Hero Culture in the New Era and Innovative Research on Ideological and Political Work of College Students" and "Hero Culture Propaganda in the New Era and Innovative Development of Ideological and Political Work of Colleges and Universities", and made efforts to integrate excellent hero culture into ideological and political education and teaching of college students in an effective way, so that the younger generation can strengthen their ideals and beliefs and become the pillars of the country.

In 2012, he applied for the national major cultural project "Biography of China’s History and Culture", and his concluding achievement "The Traveler of Heaven and Earth: Biography of Wang Fu" was published by Writers Publishing House in 2016, and the preface of the famous writer Tang Haoming was published in Guangming Daily. After that, it took him more than six years to complete the writing of the three-volume novel Wang Chuanshan, which will be launched by Unity Publishing House in early 2024.
