The canteen originated in the summer and autumn of 1958. At that time, it was called "public canteen" and was organized by the government. It was the time of political madness, and it was completely ineffective for farmers to pretend to be poor to fight against this madness, so setting up public canteens was just one of a series of romantic fanaticism. People get steamed buns and eat in public canteens. At first, the canteen was "prosperous". The canteen trust includes two important subjects: one is the dining party, that is, the trustee of the canteen, including factories, schools, hospitals, hotels and other enterprises or organizations (hereinafter referred to as Party A); Secondly, the custodian of the canteen, generally a professional catering company with catering service qualification (hereinafter referred to as Party B). All canteen staff must hold health certificates issued by relevant institutions, which meet the professional standards of catering industry. The catering raw materials used should be purchased from places with health and epidemic prevention qualifications as planned, and invoices should be requested. It is forbidden to purchase rotten food to prevent food poisoning, especially to disclose the procurement channels of non-staple food to employees.

All cooks should pay attention to hygiene. Wash your hands frequently, cut your nails frequently, change your work clothes frequently, and wear work clothes during office hours. Cooks should have a health check-up once a year, and they are not allowed to work in the canteen without a health certificate.
