I opened a restaurant in Guicheng Shiken, Nanhai, Foshan, and now I am told that the business license cannot be obtained because of housing. Is this true? Is there any other way?

Civil residences cannot be registered for business licenses, and civilian residences can be converted into commercial buildings:

If the owner changes the residence into a commercial building, in addition to complying with laws, regulations and management regulations, he must go through Interested owners agree.

If an owner changes a residence into a commercial building, other owners in the building shall be recognized as "interested owners." If owners outside the building within the building zoning district claim to have an interest, they should prove that the value of their houses and quality of life are or are likely to be adversely affected.
