1, old house. Most of the houses were built in the 1980s and 1990s. They are relatively old, and there are a considerable number of one-story bungalows, some of which are even dangerous buildings.

2. The infrastructure is backward. Road congestion, poor drainage, lack of sewage treatment facilities, no standardized vegetable market, parking lot, etc.

3. Lack of management level. In the aspect of city sanitation management, there is a cleaning team but no long-term measures, and the underground drainage pipe network is not ideal and seriously blocked. The problem of dirty, disorderly and poor is more prominent, the management of vehicles in the core area is chaotic, and the phenomenon of parking and parking at random blocking traffic is common.
