1. Determine whether the person changing hands is the landlord or the lessee. If you are a landlord, you should ask the landlord to produce a valid property rights certificate, and check the building area, structure, etc. based on the property rights certificate.

2. Check whether there have been any records of violations of laws and disciplines. Go to the industrial and commercial administration department and tax department in person to find out whether the industrial and commercial administration fees and taxes payable have been paid in full, and whether there are any fines.

3. Are there any financial disputes with former employees?
