*** From the national speed skating hall located in Orson park to the main media center of Beijing Winter Olympic Games and winter Paralympic Games, Beijing Winter Olympic Village (winter Paralympic Village); From the dispatching center of Beijing Winter Olympics operation headquarters in Shougang park to the ice and snow project training base of Erqi plant near Lugouqiao, they came in the cold and returned in the dark. *** "Every step has come steadily. Now it's the sprint stage. I think everyone's work is still going on in full swing. Let's make another effort." Look, think and cheer all the way. Looking back on the past, from the moment of celebrating the success of bidding for the Beijing Winter Olympics in the summer of 2015, China has reversed the construction period every day, January and year. Sports to the country is a symbol of national strength and a symbol of national cohesion. From the "Olympic three questions" a hundred years ago to today's "double Olympic city", *** Chinese characteristics: "Highlight the characteristics of science and technology, wisdom, green and Thrift" All the way north along the central axis of Beijing, overlooking from the air, the national speed skating hall is like a crystal track carved by an ice skate on the ice. Its other name is "ice ribbon", hence its name. The visit began with the only new ice competition venue for the Beijing Winter Olympics. Since the first pile was laid on January 23, 2018, the construction of "ice ribbon" has "high aspirations". *** Fast, from technology. As early as 2019, when the general secretary inspected the preparations for the Beijing Winter Olympics for the third time, he specially stressed that the venue construction should highlight the four characteristics of "science and technology, wisdom, green and Thrift", and science and technology is the first. *** "Is the localization rate high?" "The 'domestic cable' used in the roof cable net structure is produced in Hebei; 'ice ribbon' 3360 curved glass are produced in Tianjin; the concrete viewing board at the foot is produced in Beijing." The person in charge of venue operation said interestingly that the construction process is also "the integration of Beijing, Tianjin and Hebei". A number of "Chinese plans" for the construction of Winter Olympic venues composed of Chinese design, Chinese technology, Chinese materials and Chinese manufacturing have become the distinctive "Chinese characteristics" of the Beijing Winter Olympic Games. The general secretary came to the track and listened carefully to the introduction while watching the track test data: "at the foot is a stainless steel pipe with a length of more than 120 kilometers. The liquid carbon dioxide flowing in the steel pipe ensures that the temperature difference on the ice surface does not exceed 0.5 degrees Celsius, so it can form the most complete, uniform and fast ice." "Technology" enables "green". *** From the beginning, the Beijing Winter Olympics took a "green script". For the first time in the history of the Olympic Games, we have realized the full coverage of green power in all venues, the transformation and application of many scientific and technological achievements such as energy conservation, low-carbon energy, waste and wastewater treatment, and gathered into a vivid sample of the new development concept in the practice of the Winter Olympic Games. Post game utilization is a world problem. *** "We are all sustainable reuse." *** He also specifically mentioned a case of "building nests to attract Phoenix", Beijing Winter Olympic Village (winter Paralympic Village). *** The three entry courtyard with quadrangle style is the "home" of global Olympic athletes during the competition, and will be transformed into a Beijing Talent apartment with a wide range of talents in the future. The general secretary praised: "this practice is very good and reflects sustainability. This is our concept. We should consider its sustainability and overall planning not only for this matter." Athletes and coaches' food, housing, transportation, medicine, health and happiness finally rest on intelligent management and fine service. How is the operation support progressing? The general secretary walked into the comprehensive clinic and the model room for disabled athletes. A convenient barrier free facility left a deep impression on the general secretary. There is a button in the bedroom of the model room. Just touch it with your elbow and the cabinet door will open. "It is said that in the past, most of the problems were reflected in the Olympic village. To build a safe, warm and comfortable 'athlete's home', we should deal with the details, think about what the athletes want and what the athletes need." Preparing for the Winter Olympics is a systematic project and a comprehensive examination paper of national strength. *** In the Winter Olympic Village, a group of volunteers from colleges and universities are also vivid "Chinese business cards". The general secretary exchanged cordially with them, and the vigorous youth infected the scene. "Although you have worked hard, you are glorious, proud and happy. It will be an unforgettable life experience to tell the participants of all countries about an ancient and modern Beijing and let them feel the hospitality of the Chinese people." "Please rest assured, General Secretary!" The sonorous vows of the young generation have echoed for a long time. Solemnly undertake: "We promise to do it well" The Winter Olympics, the promise of China. *** I don't know what's going on. How many times, how many times to overcome difficulties, the "Winter Olympic blueprint" has become a reality step by step. All 12 competition venues were completed ahead of schedule, three Winter Olympic villages were delivered on schedule, and the Beijing Zhangjiakou high-speed railway and Beijing Lijiang expressway were opened to traffic; When Beijing first submitted the bid report, it proposed "taking athletes as the center, sustainable development and thrifty hosting competitions", which has rich and vivid practice *** The sudden outbreak of novel coronavirus pneumonia has disrupted the pace of world sports. The foresight of "early but not late" has once again amazed the world at China's preparedness. *** Facing this test, China has made full preparations. That morning, the general secretary walked into the main media center of Beijing Winter Olympic Games and winter Paralympic Games. During the games, as the headquarters of registered print media and broadcasters around the world, thousands of Chinese and foreign journalists will gather here. How to manage under the epidemic situation? What should I do? *** He stressed: "closed loop management is very necessary, the design must be scientific and reasonable, and the smooth holding of the Winter Olympics cannot be affected by the rigidity and simplicity of management." The smart restaurant in the main media center is built for better epidemic prevention and control, all of which are independently developed by China. A robot shakes the wine glass and makes cocktails; There are robots busy splashing water and cooking dumplings. The general secretary was very interested: "there is a stress on cooking dumplings. The cover is the filling, and the cover is the skin." During the conversation, the delicious dumplings came out of the pot. "How does it taste? Has the chef tried it?" The general secretary asked with a smile. "Robots are apprentices of chefs." The staff answered with interest. There are more than 200 dishes and recipes. Once the mobile phone scans the code, the robot in the back kitchen is busy, and then the dishes are accurately delivered to each table through the cloud track system above the restaurant. "The development of artificial intelligence catering industry has realized the standardization of production and the refinement of epidemic prevention and control." The general secretary praised. The media workroom is the distribution center for the Winter Olympic Games. The reporters who were making preparations here saw the general secretary and enthusiastically gathered around him. "Affected by the epidemic situation, the on-site viewing of the Beijing Winter Olympic Games and the winter Paralympic Games is greatly limited, and news communication is more important than ever." The general secretary smiled and said to everyone: "I hope that domestic and foreign media and journalists can tell the story of the passion and hard work of Olympic athletes in various countries, the story of China's preparations for the Winter Olympics, and the story of the hospitality of the Chinese people, so as to comprehensively, three-dimensional and vividly spread the Beijing Winter Olympics to the world." There are three competition areas in the two places, one game of chess and one strength. Behind this, "command center" is the dispatching center of Beijing Winter Olympic operation headquarters. *** The dynamic data and images on the large screen are updated in real time. An emergency support team is waiting for success; The meteorological changes, traffic conditions and other information of each competition venue are accurately transmitted. "Despite the impact of the epidemic, the preparations for the Winter Olympics are progressing very smoothly, which is almost a miracle!" The Chinese power expressed by IOC President Bach is once again confirmed here. *** *** Over the past six years, he has repeatedly stressed that "every promise will be fully fulfilled" and "it will be done well". It is a consistent style of China to abide by its promises. Historical changes: "The goal of 'driving 300 million people to participate in ice and snow sports' has been achieved ahead of schedule" The last stop of the investigation was the ice and snow project training base of Erqi plant. In the spring of 2018, Erqi plant, which has a history of more than 120 years, stopped production and transformed into a national ice and snow transportation
