1. Chinese people have some resistance to the system of separate meals. Dinner plays an extremely important role in China people's social activities. People rely on dinner to connect their feelings, and disputes are often solved through dinner. Dinner has even become a belief. During the Spring Festival, hundreds of millions of people have crossed Qian Shan and many barriers, and migrated at the highest frequency and on the largest scale, just to have a reunion dinner at home.

2. It is also difficult for catering enterprises to operate in practice. On the one hand, some special dishes are not suitable for sub-packaging, and dishes with carving and special plate setting skills need to ensure the integrity of the dishes when serving, and it is difficult to implement standardized production for some Chinese dishes; On the other hand, the separate meal system will inevitably increase the cost of manpower and material resources, and at the same time cause the consumption of water resources and washing products to rise.

3. The lack of knowledge education about meal sharing is also an important reason for the weak awareness of meal sharing. For a long time, eating separately is not in students' health education textbooks, healthy lifestyle education for adults, and it is not widely publicized like "washing hands before and after meals", which shows that our national health education still needs long-term efforts.
