Excuse me, is it Class A or Class B to apply for a health certificate when going to work in a restaurant?

At present, the card-type health certificate is divided into two types: A and B.

Class A refers to the work directly related to food, or any work that requires a health certificate.

Class B refers to jobs that are not directly related to food.

(One is only for physical examination, valid for 1 year;

There is also a physical examination and a training examination, which is valid for 2 years. )
