catering service units belong to public places. According to the Regulations on Hygiene Management of Public Places, this type of public places need to obtain a "Hygiene Permit". The health department should only require operators to apply for the Health Permit according to the Regulations. However, in most places, the health departments have not legally issued the Hygiene Permit to catering units, and catering service units only need to obtain the Catering Service Permit. Article 2 of the Regulations on Hygiene Management of Public Places stipulates that "these Regulations shall apply to the following public places: (1) hotels, restaurants, hotels, guest houses, chariots and horses shops, cafes, bars and teahouses; ..... "At the same time, Article 8 of the" Regulations "stipulates that" a business unit may apply to the administrative department for industry and commerce for registration and apply for a business license only after obtaining a "health permit". Those who have started business before the implementation of these regulations shall be reissued with a "health permit" after passing the inspection by the health and epidemic prevention institutions. The "health permit" is reviewed once every two years. "
