When it comes to Xu Zhimo's poems, I will naturally think of Lin, I will definitely think of Liang Sicheng and his wife, and I will definitely miss the old city wall, the city gate of old Beijing, and the ancient buildings that only leave place names all over the country.

1949 after the founding of new China, Mr. Liang Sicheng also served as the deputy director of the Beijing Municipal Planning Commission. He insisted on protecting ancient buildings and walls. Together with Mr. Chen Zhanxiang, who is also a famous architectural expert, he put forward the "Good Chen Plan" (a suggestion on the location of the administrative center of the Central People's Government): to build another new city in the west of Beijing, Chang 'an Avenue is like a pole, stirring up the new old city of Beijing.

You can build a flower pond, plant shrubs such as lilacs and roses, or spread some grass, plant some grass flowers and put some garden chairs. At dusk in summer, hundreds of thousands of people can enjoy the cool and rest. In the crisp autumn season, people living in the city can climb high and overlook the whole city, the gray western hills in the northwest and the endless plains in the southeast, all of which are so close to nature and have a magnificent mind. There are also towers and turrets that can be turned into cultural centers or small libraries, museums and tea shops; The moat can lead into Yongding River, boating in summer and skating in winter. Such a three-dimensional park around the city is unique in the world ... ".
