The concept of "eating" is formed by steaming rice and cooking porridge. What is a meal? Rice and porridge are cooked cereals, and they are also the general names of foods that people often eat every day, including main and non-staple foods. The ancient book "Ji Cai's Soup" ("Da Dai Li Ji") refers to a meal composed of staple food and vegetable soup. This is a new change in the diet structure of our nation brought by "steaming grain for rice" in the era of the Yellow Emperor. In the early days of primitive society, our ancestors lived mainly by hunting, fishing and collecting fruits and stems of wild plants, often mainly by eating meat; Since the era of the Yellow Emperor, with the development of agriculture, people's one-time eating has changed to dinner, supplemented by vegetables and a small amount of meat, which is also a dinner. This diet has continued to this day. In the later period of primitive society, the population gradually increased, and the ready-made food raw materials became less and less. The Yellow Emperor led his subjects to slash and burn and develop primitive agriculture. On the vast land of the Yellow River Basin, flat green fields have appeared. The "five arts" advocated by the Yellow Emperor is to widely plant five grains, namely millet, millet, rice, wheat and rice. His "comfort everyone" approach, first of all, is that Guan Xinmin cuisine has solved the problem of people's eating. In this respect, the Yellow Emperor and Yao, Shun and Yu who inherited him are all models. China food culture has a long history and profound connotation. Understanding China's food culture can help us better understand the taste of China cuisine and appreciate the ancient cultural traditions of China.
