What if the landlord doesn't give the release form and the property doesn't come out?

First of all, it must be clear that neither the landlord nor the tenant of the property has the right to prevent it from entering and leaving the community.

Legal basis:

Article 271 of the Civil Code of People's Republic of China (PRC) * * * The owner has the ownership of the exclusive parts of buildings such as business buildings, and * * * has the right to jointly manage the parts other than the exclusive parts.
