Abstract: As one of the four classics of Chinese medicine, the Treatise on Cold Damage has an irreplaceable position in both Chinese medical theory and clinical practice. However, it is still necessary to explore the meaning and criteria of classicality in Chinese medical texts and the current research strategies. As a discipline that explores the relationship between text, author, and reader, as well as understanding and interpretation, hermeneutics has received much attention in the field of humanities and social sciences for its truth outlook, theory of textual understanding, and theory of practice. Through applying the theories and methods of hermeneutics, some characteristics including classicality, originality, as well as authority of the Treatise on Cold Damage can be elucidated. In addition, through exploring and understanding the connotation of truth and the practice, the text in the current clinical practice can be further interpreted to provide reference and inspiration for the study of the Chinese medicine classics.
