The ancient city is a cultural point left over from history. It is not just a rigid city, but a place where people live. Many people live a full life, and it is difficult to transform an old city. It turns out that at the beginning of the founding of New China, Mr. Liang Sicheng wanted to keep the old Beijing city intact as a history museum. Later, the country learned from the experience of urban construction in the former Soviet Union and wanted to transform the old city. Some old houses in the old city were demolished and buildings were built on the basis of dangerous buildings. First, experiments were conducted in the suburbs, and buildings were built in the suburbs. More than 20 years have passed, and the old suburbs are almost built. In the past 20 years, when he entered the city, he first began to build and tear down a piece of the central government office building in the city, that is, build one piece and build another. For example, most of the houses occupied by troops in the city have been demolished and built.

In this way, the development of the old city has become a "nail house" type, and it is gradually increasing. Later, in the past ten years, houses in Beijing were torn down one by one and covered in large pieces. Its development trend will be that almost all the old residential buildings in the city will be demolished, and all the buildings will be built in both urban and suburban areas. There is a Forbidden City in the center of Beijing. The palaces in the Qing Dynasty are basically bungalows, which are equivalent to the height of two or three floors. Houses around the Forbidden City will be gradually raised in the planning. In the suburbs, plan in pieces and build high-rise buildings at the same time. Now, if you go to Beijing and climb to the top of Xishan Mountain, Beijing is already full of tall buildings. Beijing's construction in this way has a great influence on cities all over the country, and other cities in the country have followed Beijing's example and gradually built houses in the old city, with fewer and fewer old houses. If factories and industrial areas are to be built, they will be built in the outer suburbs of the city. After a long time and dense buildings, there will be no big difference between outer suburbs and suburbs.

Among them, there are several problems. First, protect important ancient buildings, ancient cultural relics and important Buddhist temples, such as big temples, Taoist temples, towers, academies, churches, memorial archways and businesses. Such a building has been appraised by the state, and the cultural relics policy stipulates that it is basically immovable. In this way, when new buildings are built, these ancient buildings and cultural relics should be preserved, and a certain amount of land and a certain distance should be reserved as required.
