You need a health certificate to go to a tea shop for a summer job, and you need a health certificate to go to other places, not to mention the tea shop, which is a beverage store, especially during the epidemic. The validity period of the health certificate can be one year, which can be used by summer workers or during the winter vacation.
No matter whether you work in the food and beverage department for a long time or a short time, you must have a health certificate before you can take up your post, because tea shops are drinks, and workers have a high frequency of contact with food. If I have infectious diseases, I am particularly prone to cross-infection. Units and individuals who employ people without health certificates without authorization will be dealt with severely once they are investigated.
