"From all angles, we give the Beijing Winter Olympics a very high score." Christopher Dolby, executive director of the Olympic Department of the International Olympic Committee, said recently that the preparations for the Beijing Winter Olympic Games have made many achievements, which are admirable. For some time, some western countries have engaged in the so-called "not sending officials to attend the Beijing Winter Olympic Games" in an attempt to politicize sports and use the Olympic Games as a political weapon to contain and suppress China. However, we eliminate noise interference, always calmly and orderly promote the preparatory work, and concentrate on doing our own things. From site selection planning to careful design, from intense construction to operation test, since the preparation for the Winter Olympic Games was launched, we have adhered to the concept of "green, sharing, openness and integrity", strengthened confidence, worked hard, not afraid of difficulties and challenges and overcome the impact of the epidemic. After more than 2000 days and nights, the preparation for the Beijing Winter Olympic Games has won extensive support and recognition from the international community. Behind this is China's firm commitment to successfully hosting the Beijing Winter Olympic Games and the winter Paralympic Games, the Chinese strength with the concerted efforts of the people of the whole country, and the sonorous pace of scientific and technological innovation. The venue design is full of ingenuity, 100% use of renewable energy and many innovative measures. The elements mentioned in Dolby's interview are also the highlights of the preparations for the Beijing Winter Olympic Games. For example, as the top priority in preparing for the Winter Olympic Games, the venue construction shows rich connotation. 12 competition venues have been completed and meet the conditions for hosting the games. Winter Olympic venues such as "snow Ruyi" and "ice ribbon" are full of traditional Chinese poetry. For example, in the face of construction difficulties and asking for answers from scientific and technological innovation, the national snowmobile and sled center walked out of China's road of independent innovation and realized one-time spray pouring of 1.9 km track concrete. For example, adhere to ecological priority, resource conservation and environmental friendliness. All venues will use renewable energy for power generation, "light up the Winter Olympic lights with Zhangbei wind", showing the background of beautiful China. If the construction of the front hall reflects the orderly progress of the preparations for the Beijing Winter Olympic Games from the static level, the whole process and all elements of the series of test competitions have actually tested the competition streamline. As a large-scale "simulation test" on the eve of the Beijing Winter Olympic Games, from October to December, the "meet Beijing" series of test events fully refer to the standards of the Winter Olympic Games, including 10 international test events, 2 domestic test events and 3 international training weeks. The competition venue facilities, venue operation mechanism, epidemic prevention and control measures and event service guarantee have been tested and tested in an all-round way. From the test results and feedback from all parties, the "quasi Olympic site" has gained a good reputation. The event is running well, the service guarantee shows humanistic care, and the epidemic prevention and control is integrated... The "simulation test" not only reflects that the preparation work has been improved, but also lays a solid foundation for holding the main event on schedule, safely and smoothly. While striving to write the answer sheet for the preparation of the Winter Olympic Games, we also strive to hand over the answer sheet of the era of regional coordinated development. We will organize the Beijing Winter Olympic Games and play a leading role in the full implementation of the coordinated development strategy of Beijing, Tianjin and Hebei. A series of transportation networks such as Beijing Zhangjiakou high-speed railway and Beijing Lijiang expressway have been accelerated, and the construction of Beijing Tangshan and Beijing Binhai intercity railways has been comprehensively accelerated, so as to plug in the wings of high-quality development in the region; A number of old enterprises have realized transformation and upgrading, revitalized the capital iron and steel Park and realized industrial transformation and development. The original industrial sites have now become "online Red punch in places"; Ice and snow are also golden mountains and silver mountains. The continuous rising "ice and snow enthusiasm" of the whole people has made Chongli a gorgeous transformation; With the help of the sports platform, the ecological resources and cultural history of Beijing and Zhang are being transformed into new economic growth points... From ice and snow to the new appearance of urban and rural areas, from "one hour traffic circle" to complementary advantages and resource sharing. The preparation for the Beijing Winter Olympic Games has driven all aspects of construction and added color and energy to the coordinated development of the region. The chain reaction brought about by the Beijing Winter Olympic Games is gradually emerging, and the Winter Olympic vision of "sustainable · to the future" is becoming clearer and clearer. We have the confidence and ability to present a "simple, safe and wonderful" Olympic event for the world. We will also submit two excellent answers for the preparation of the Winter Olympic Games and local development. (outlook new era)
