Should the health certificate of Mi Xue Bing Cheng be hung on the wall?

Need. Food and drug supervision and management departments and agricultural departments will randomly check whether there are food safety hazards in milk tea shops, so the health certificate of Mi Xue Bing Cheng should be hung on the wall to prevent it from being taken out directly during inspection. If you don't check, you will be fined. The health certificate is valid for one year, which is mainly a certificate issued by an authoritative national medical institution. It is valid anywhere, but only within the validity period. After the expiration date, it will have no effect.
