Overdevelopment of real estate in China has become a common phenomenon, and there are more and more ghost towns in China, so many cities don't need to build new buildings for ten years. It is a fact that the unprincipled loans of banks have been alleviated or even deterred by various means, so the life of developers is very difficult. In the face of the decline in the market value of the house, the house has been paid in advance, but the house is not available and many developers have run away. Every city has this problem, and the people who suffer in the end have worked hard to return to a few years ago. Sigh.

But I don't think it's effective to send a message for help here. People who are concerned about "knowing" are ordinary people, and people from "relevant departments" will not take the initiative to help you solve it even if they see it here. I suggest you appeal through formal channels.
