According to the health certificate, my job is food, but I'm a caterer, okay?

At present, "health certificate" is divided into two categories: A and B. People who hold Class A health certificate can engage in any industry and type of work that requires health certificate. Class B health certificate holders can only engage in non-food businesses, guest rooms, security guards, receptionists, parks, stadiums, bookstores and other industries and jobs.

Since the landlord has a Class A health certificate, it is ok to try it in the supermarket.

In addition, the health certificate is valid for one year, and it will expire after more than one year.

Tasting activities ensure the health and safety of both parties. As long as your health certificate has not expired, there should be no problem doing these part-time jobs. I hope this answer can help, and the landlord can take up his post as soon as possible, hehe.
