Which city in China has been demolished for more than two generations?

At present, the city with the largest number of second-generation dismantling in China should be Shenzhen. With the development of urbanization, Shenzhen has become one of the largest immigrant cities in China. Especially in the process of urban village reconstruction, a large number of demolition actions have caused the number of second-generation demolition to rise linearly. In addition, in the process of urban renewal and urban transformation, the Shenzhen Municipal Government has been actively promoting the demolition of a large number of old buildings, thus further promoting the increase in the number of second-generation demolition. Of course, this has also triggered a series of social problems, and the government needs to pay more attention to people's livelihood and social equity in the follow-up treatment.
