1, unclear property rights. In some cases, unclear property ownership may become an obstacle to demolition. The ownership of dormitory is controversial or unclear, which will lead to the government's failure to carry out demolition.

2. Demolition compensation. Demolition involves a large number of compensation costs and resettlement issues, and the government cannot provide suitable compensation and resettlement programs, which will lead to the failure of demolition. In addition, residents are not satisfied with the compensation scheme, which also hinders the demolition.

3. Environmental protection. In some cases, demolition involves environmental protection. There are environmental problems in the dormitory area, which need to be solved before demolition.

4. Social stability. In some cases, demolition involves social stability. If there are social problems in the area where the dormitory is located, or some groups resist the demolition, the government will consider suspending the demolition to maintain social stability.
