What does the catering system mean?

When it comes to catering system, I believe everyone is familiar with it. It can often be seen in daily life. What makes everyone curious is, what does the dining system mean? In fact, the separate dining system refers to the principle that chefs, waiters or family members distribute staple food and dishes to tableware in equal amounts, so that each diner can enjoy it alone, which is relative to the "combined dining" in which many people use one or several dishes. Separate meals can reduce cross-infection, reduce food-borne diseases and infectious diseases, and cultivate good and healthy life behaviors. Moreover, the separate meal system is of far-reaching significance for reasonable diet, balanced nutrition, control of food intake and prevention of chronic diseases such as obesity, diabetes and cancer.
