First, the health-keeping movement of traditional Chinese medicine is rising in the rising sun. Since it is in exercise, the human body will get hot and sweat, and it will consume the vulva substances in the human body. The vulva in the human body is mainly water, so TCM health-keeping exercise needs to replenish water and nourish yin in time. Second, Chinese medicine believes that water can be divided into raw water and cooked water. There is no boiled raw water, "cold drinking will hurt the lungs" and stimulate the stomach. After "fire roasting", the boiled water cooled by fire is mixed with yin and yang, which is more suitable for the needs of viscera and easier to digest and absorb.
