"Building and managing the capital well is an important part of the modernization of the national governance system and governance capacity." Zhao Li, the former executive deputy curator of Beijing Planning Exhibition Hall, still remembers the scene at that time: "the general secretary has a detailed understanding of Beijing's geographical environment, planning layout, functional positioning and so on, and asked very detailed questions. He is very concerned about the problems existing in the development of the capital, such as overpopulation, traffic congestion, rising house prices, severe ecological environment and so on." We will highlight Beijing's advantages and activate Beijing's factor resources more widely. A new stage of development of great synergy.

Now, by the Universiade River, the construction framework of Beijing's urban sub center is slowly opening, and the former shanty town has become the canal business district. In November 2021, the State Council issued the opinions on supporting the high-quality development of Beijing Urban sub center, which is full of vitality and the enthusiasm of the officers to start businesses. In the next step, Beijing will continue to implement the "Beijing Tianjin Hebei coordinated development planning outline", strengthen cooperation with Tianjin and Hebei, and build a modern capital metropolitan area with relief as the starting point, hinterland expansion as the support, and integration as the path, so as to drive the formation of a world-class Beijing Tianjin Hebei Urban Agglomeration. He pointed out that a remarkable feature of old Beijing is the Hutong. We should pay attention to preserving the characteristics of Hutong, so that the city can retain its memory and let people remember nostalgia. Beijing has a history of more than 3000 years and 860 years. Its rich historical and cultural heritage is a golden card. "I'm very familiar with this alley. I'm here today to see the old neighborhood and listen to your ideas on the transformation of the old urban area." In some old urban areas, residents can voluntarily choose to "go or stay". Those who move out live in modern buildings; Retaining residents use vacated space to improve living conditions and assemble modern kitchen, bathroom and other facilities. The reporter saw in No. 30 courtyard of yu'er Hutong that the illegal construction for many years has been demolished, the ground has been set aside green space, and the courtyard has restored the primitive appearance of green bricks, grey tiles, red doors, and green lattice windows.

The protection of Beijing's old city has been carried out step by step." Chen Mingjie, director of the Beijing Municipal Bureau of cultural relics, said that in the future, the protection of the central axis of Beijing will be an opportunity to inject new impetus into the prosperity and development of Beijing's historical and cultural heritage. "Manage and make good use of the Beijing Winter Olympic heritage" with the successful holding of the Beijing Winter Olympic Games and the winter Paralympic Games, Beijing has become a "city of double Olympics". From the bid to the preparation, and then to the successful holding, the general secretary repeatedly told: "hosting the Winter Olympics is not a one-off deal", "it needs to be combined with the use after the games, and do not engage in extravagance and luxury, and do not engage in repeated construction"...

Wu Xiaonan, director of the operation team of the national speed skating hall, said: "the important instructions of the general secretary point out the direction for the long-term sustainable development of the 'ice ribbon'. We should build the 'ice ribbon' into an urban sports complex and become a business card for the development of ice and snow sports in China."
