Snowmobile and sleigh track "Ice ribbon" of national speed skating hall with "smart venue" as its feature rises Xiao Zhen, an employee of an Internet company in Beijing, loves skiing very much. According to her introduction, she used to take someone else's car or bus to go skiing in Chongli, with a journey of 4 to 5 hours. After the opening of the Beijing Zhangjiakou high-speed railway, the time from Beijing to Chongli was shortened to one hour. Xiao Zhen tried to ski on the high-speed railway for the first time. At the Beijing Winter Olympic Games, athletes from all over the world can take this train to and fro between various competition areas, and feel the real speed of China in the Winter Olympic Games. When the Beijing Zhangjiakou high-speed railway was put into operation, General Secretary Xi Jinping made important instructions and stressed that the Beijing Zhangjiakou high-speed railway is an important supporting project for the Beijing Winter Olympic Games. Its opening and operation marks new progress in the supporting construction of the Winter Olympic Games. Other preparatory work should also be advanced with high standards and high quality to ensure the smooth holding of the Winter Olympic Games as scheduled. With the opening of the Winter Olympic Games getting closer and closer, the achievements of the Beijing Winter Olympic Games are also appearing in front of the public one by one. In xiaohaituo mountain, with an altitude of 2198 meters and a maximum gradient of 68 degrees, the construction of the national alpine skiing center has been completed through the unremitting efforts of the team members. Not far from the landmark "bird's nest" of the Beijing Olympic Games, the "ice ribbon" of the national speed skating hall with the characteristics of "smart venue" has sprung up. The national snowmobile and sleigh center is the first snowmobile and sleigh track in China and the first 360 degree racetrack in the world. The construction process has filled many technical gaps in China. The national ski jump center "xueruyi" combines the ancient Chinese "Ruyi" shape, realizing the organic combination of architectural design and Chinese traditional culture. The Beijing Organizing Committee for the Winter Olympic Games and the governments of the two places jointly implement the spirit of General Secretary Xi Jinping's important instructions in depth. In 2020, we will make every effort to promote the construction of venues and infrastructure by focusing on both epidemic prevention and control and the preparation for the Winter Olympic Games. By the end of 2020, all competition venues of Beijing Winter Olympic Games will be completed as planned. Just like the Beijing Zhangjiakou high-speed railway, the preparations for the Winter Olympics once again highlight China's speed.
