Shijiazhuang, a city in northern China, plans to build three more subway lines in addition to the existing three. Among them, Line 4 is the most special. It can be inferred that this line does not serve the urban area, but serves the countryside, and the subway has become a tool for urban development.

As urbanization accelerates, more and more historical neighborhoods are disappearing. These neighborhoods represent the memory of a city. Wenzhou is a small coastal city located in Zhejiang Province, China. In many blocks of this city, new and old buildings coexist.

Young IT workers envy the relatively free life of IT workers around 35 years old, while IT workers around 35 years old also have a sense of crisis in life because of their age.
