Tea culture in China has a long history, and drinking tea is a good way to keep fit. Various teas have different effects, and there is no distinction between good and bad. Generally speaking, they can regulate body metabolism and cultivate temperament in the process of drinking tea. All-natural products are of course the best, and too much processing is unfavorable. Of course, some tea leaves need post-processing, such as cooked Tieguanyin. It depends on what kind of tea you choose, according to the season and physical condition, and the specific purpose of health preservation (beauty beauty, self-cultivation, etc. ), and the four characteristics of tea: warm, cold and cool.
