For ancestral halls and other land, first of all, it should be reported to the local land management department for examination and approval. Every place has a policy on this kind of land according to local traditions, and it needs to be built after approval, otherwise it will be regarded as illegal construction. Specific procedures, you should first negotiate with the existing contractor and the village committee, and the village committee will come forward to adjust the contracted land for it, and then the proposer will negotiate compensation with it. Then the village committee will use this land for rebuilding the ancestral temple through the resolution of the villagers' representative meeting, and then apply for a building permit from the government department with these written materials.
