The author of this book has provided detailed annotations after experimentally elaborating on Zhang Zhongjing's works. The book has three main features: (1) It summarizes the author's decades of clinical experience, with every phrase reflecting personal insights, differing from the usual compilations of previous commentaries; (2) It integrates the entirety of Zhang Zhongjing's works, adhering to the spirit of his writings, offering detailed analyses without seeking novelty or being confined to the biases of any single school; (3) In explaining each section, the book not only analyzes the pathology but also extensively cites the author's years of clinical experience as evidence, enabling readers to understand how to apply the knowledge, distinguishing it from works that merely offer empty theories without practical application. This book is a valuable reference for those studying Chinese medicine and for clinical practitioners today.
