Abstract: Since TCM classics contains a large amount of Confucian and Taoist thoughts,Confucianism and Taoism are of great value in interpreting them. This paper takes LIU Wansu's interpretation of Suwen and the creation of the theory of Huore as an example to explore the way of the interpretation of TCM classics by Confucianism and Taoism. The results show that it is the cornerstone of the theory of Huore to investigate the principle of things and interpret by image taking and analogy, the Wuxing and the images they form are the basis for the interpretation of the Liuqi Huahuo. Confucianism and Taoism are combined to explain TCM theory, Shangshanruoshui with Xiayuruhuo is the basic principle of LIU Wansu's interpretation of Wuzhihuahuo. Since the Gewu is only a general understanding of things, it is not necessarily true knowledge to apply the Confucian and Taoist methods to understand things in the medical field. LIU Wansu finally combined with the clinical experience to verify the theory of Huore.

Key words: Confucianism, Taoism, classics of traditional Chinese medcine, interpretation, the theory of Huore
