Why not demolish the five Dong Lei settlements?

The reasons why Wutai Dong Lei immigrant areas are not demolished may involve the following factors:

1. Policy factors: The government may have established five resettlement areas in Dong Lei according to relevant laws, regulations or policies to protect the legitimate rights and interests of local residents. These policies may include land and housing demolition and resettlement compensation policies. In order to protect residents' life and social stability, the government may decide not to demolish the area for the time being.

2. Social stability factors: Demolition may have an impact on local social stability, especially when it involves large-scale demolition. The government may consider social stability factors, avoid intensifying contradictions and conflicts, and choose not to demolish for the time being.

3. Economic development factors: Demolition may involve the reuse of land resources and the planning of economic development. The government may be carrying out relevant planning, such as urban renewal and industrial transformation, and it needs time for technical research, social investigation and policy formulation, so it decides not to demolish for the time being.

Please note that the above are the possible reasons for my speculation. If you need more specific information, I suggest you consult the relevant government departments or learn about the planning and policies of the local government.
