Let me give you a list of steps:

1. Go to the district and county CDC for physical examination and get a health certificate. 2. Go to the industrial and commercial branch of the jurisdiction to approve the name of the tea shop with a copy of the ID card and proof of business premises (a copy of the store rental contract and the lessor's property right certificate (that is, a copy of the property right certificate or the property right certificate issued by the Housing Authority and neighborhood committees), and obtain a notice of pre-approval of the name. 3. Hold the health certificate, ID card and name pre-approval notice until the Food and Drug Administration handles the catering service license. 4. Go to the industrial and commercial branch office to apply for the business license of self-employed, copy of ID card, proof of business premises, copy of catering service license, 4 one-inch photos, and proof of marriage and childbearing of floating population (not required in some places). 5. Post the original catering service license and business license in a conspicuous position in the storefront and start business.
