Tang Zong-hai authored, completed in 1884, the book consists of eight volumes. It is a monograph by Tang on hemorrhagic syndrome. The book is rich in content and clearly organized. In it, he first elucidates the roles of Yin-Yang, Water, Fire, Qi, and Blood in the human body, as well as the relationship between hemorrhagic syndrome and the zang-fu organs. Secondly, he categorizes the symptoms of hemorrhagic syndrome and details the methods of differentiation and treatment, listing specific prescriptions and medications under each condition, making it thorough and detailed. The most notable feature of the book is its strong practicality. Due to his extensive reading of medical texts and personal practice in the study of hemorrhagic syndrome, most of the discussions in the book are based on experience. As he stated in the preface: "I have meticulously explored the profound mysteries of loss of blood, either expanding on what the ancients intended to say or supplementing what previous scholars had not covered, always striving for sufficient rationale and effective prescriptions, avoiding vague discussions." It is evident that the book Xiezheng Lun was written by summarizing the experiences and theories of predecessors, combined with his own practical insights. Therefore, this book not only provides guidance for the treatment of hemorrhagic syndrome but also serves as an important reference for research on hemorrhagic syndrome.
