In terms of diet, China attached great importance to the coordination between diet and seasons in ancient times, which was regarded as a principle that must be followed in food nutrition, food handling and drug treatment. Su Wen in Huangdi Neijing records that "you must be old first, and there is no harmony". "Sages raise yang in spring and summer, and yin in autumn and winter, so they follow their roots, so Yin and Yang are often the same, which is the foundation of life and death. If you do the opposite, you will get sick from your mouth. " These principles of treating diseases and preserving health must also be followed in diet.

Due to the influence of seasonal climate, the methods of storing food in ancient times were backward, and many foods could not be kept fresh and with good quality. Therefore, choosing different foods according to seasons is conducive to ensuring food quality and hygiene requirements.

The Zhou Li Tianguan of the Zhou Dynasty recorded the taste of the food selected in the four seasons as follows: "The spring equinox is sour, the summer is bitter, the autumn is spicy, and the winter is salty and soft." It is related to the season, so pay attention to the temperature of the diet. Bing Wang, an ancient medical scientist, said, "Spring should be cool, summer should be cold, autumn should be warm, and winter should be hot. This time is right, and there must be no problems. "

The experience of four seasons feeding in ancient times is still of practical significance until now. If you often eat some cool food and drinks in summer, you can have a cool feeling; Eating more warm and spicy food in winter can stimulate appetite, raise body temperature and make people feel warm and harmonious.
