However, it is not as simple as these principles when we really formulate the principles of four seasons cooking. On the one hand, China has a vast territory, and its climate and eating habits are quite different. For example, Sichuan and Guizhou are wet and cold in winter, and the northern region is dry and cold in winter; There are continuous spring rains in the south of the Yangtze River, and frequent spring sandstorms in northwest and north China. On the other hand, everyone's physique is different. Some people eat cold food with cold hands and feet and loose bowels; Some people have a fever and get angry as soon as they eat spicy food. Therefore, no matter what the diet principle of the four seasons is, it should be adjusted according to the specific situation, and it cannot be mechanically copied.
