From the end of the Eastern Han Dynasty to the Jin Dynasty, wars were frequent, diseases were prevalent, and the population lost a lot, but this period was also an important stage in the development of traditional Chinese medicine. Zhang Zhongjing's theory of typhoid miscellaneous diseases in the Eastern Han Dynasty laid an important theoretical foundation for TCM syndrome differentiation and treatment, and people paid more and more attention to drinking water health. Zhang Zhan of the Eastern Jin Dynasty wrote in "Health Collection": "Drinking boiled water is not sick". Although there is only the word 1 1, it clearly points out the direct relationship between drinking boiled water and preventing diseases.
This shows that people at that time clearly realized the benefits of drinking hot water, rather than learning from foreign countries after the founding of the People's Republic of China. In Han dynasty, Bashu area began to drink tea. We saw in the Nanhai agreement that one of the daily jobs of boys at home is to make tea. In the Tang Dynasty, due to the influence of Buddhism and Zen, tea began to spread all over the country. There are shops selling tea in big cities, and tea has become a popular drink. The water for making tea must boil.
Lu Yu also mentioned in the Book of Tea that when boiling water, there are one boiling, two boiling and three boiling points. When making tea, pay attention to two boiled waters and drink them "while they are hot". It is clear here that tea should be drunk while it is hot. The Book of Tea has a far-reaching influence on later generations. Tea, as a hot drink, has not changed since its spread. Perhaps it is because it is so natural for China people to drink hot tea and then plain water in China.
Chinese medicine can nourish the five internal organs because water is yin, and heat is yang, which can warm the body. A cup of hot water combines yin and yang, which is very good for the human body. Since we pay attention to harmony, the water can't be too hot. It is too hot, that is, the sun is too cloudy. The temperature of Taihe soup must be appropriate. Slightly higher than 40℃ is the best.
