If the landlord needs to complain to the industry and commerce, it should be "checked" by the industry and commerce, not "checked"; Unless you complain to the public security bureau, you will be investigated. Please choose the appropriate complaint institution according to your complaint.

Regarding the choice of complaint institutions (suggestions that meet the criminal filing standards directly complain to the public security economic investigation, and suggestions that do not meet the standards complain to the industrial and commercial economic investigation), in addition, the Bureau of Quality and Technical Supervision may also have jurisdiction, depending on the subject of your complaint.

The complaint materials provided shall be called "Letter of Request about ...". As the landlord is the obligee, the request should include: proof of rights (business license, trademark registration certificate, letter of introduction, identity certificate), infringement facts and legal demands.

How to make a good relationship depends on people and things.

As for the place of complaint, as long as there is jurisdiction.
