The Yellow Emperor's internal classic "Four Qi Regulating the Spirit" says that the way of keeping in good health comes naturally. People should change their tastes according to seasonal changes, and eat more spicy food in spring, which will help to grow hair and nourish the liver; Eating salt in summer means eating more seafood, supplementing salt and nourishing the heart; Eating some seasonal acidic fruits in autumn has the effect of astringing the body fluid and moistening the lungs; Eating barbecue in winter keeps you warm and nourishes your kidneys.

If the spring qi is violated, shaoyang will not be born, resulting in stagnation of liver qi and pathological changes; If you violate the qi of Xia Chang, the sun will be weak and your heart will be weak. If the qi of autumn harvest is violated, the Taiyin can't converge, so that the lung heat leaves are full; If you violate the gas stored in winter, you can't hide it without yin, leading to kidney gas failure, diarrhea and other diseases.

The change of yin and yang in the four seasons is the foundation of all life, so saints raise yang in spring and summer to meet the needs of growth, and raise yin in autumn and winter to meet the needs of collection, obeying the fundamental law of life development, so they can move and develop in the life process of birth, growth, hiding and hiding, just like everything else.

If you violate this law, you will destroy the vitality and the true spirit. Therefore, the four seasons of yin and yang are the end of all things and the root of ups and downs. If you go against it, you will have a disaster. If you follow it, you won't get seriously ill, so you can know the way to keep fit.

I don't know if you ate right. In the next article, I will talk about how to keep fit in autumn and winter.
