I applied for public rental housing in Kunming and have moved in. What if the government doesn't sign the contract?

I applied for public rental housing in Kunming and have moved in. The solution for the government not to sign the contract is as follows:

1. It is suggested that you can consult relevant departments to understand the specific situation, and then properly handle it according to law.

2. You can contact the local government departments or call the national service hotline 12345 for consultation and guidance on related issues and find solutions in practice.
