Traditional Chinese medicine is not solely medical science. It is broad and profound and widely used. “The upper-class research astronomy, the lower-class, geography, while the middle-class study human affairs. As big as the changes of Yin and Yang and small as the ecology of plants and insects. The sound of music, divination of luck, and the ins and out of the human organ and vital energy.” (A Preface of Lei Jing by Zhang Jiebin in the Ming Dynasty.) Chinese medicine is inclusive and can be said to be the representative and epitome of Chinese traditional culture.
