This book focuses on the conflicts between Chinese medicine and western medicine in modern Chinese society. It is trying to represent how Chinese medicine used its knowledge of exogenous febrile diseases while practicing western medicine, gradually establishing a set of TCM (traditional Chinese medicine) infectious disease studies, and carving a space to function in daily life. Initially influenced by modern medicine, many of TCM clinical techniques were marginalized. In addition, limited  national investment hindered the application of TCM theory and skills. It is the author's hope that  the study of medical history would improve the knowledge of the TMC system among traditional Chinese medical scholars and inspire researchers to acknowledge the value of a TCM culture, which had been demonized for a hundred years, providing another possibility for practical treatment and recuperation.
