This book is a collection of over a hundred medical cases compiled by Jiang Zuo-jing, a distinguished disciple of Cao Ying-fu. The cases are arranged in the order of the six meridians and are explained by referencing the profound meanings of the cold-damage disease theory from Zhang Zhong-jing, making it easier for medical learners to understand. Each case is accompanied by the disciple's notes and medical insights, providing valuable references. The book strives for detailed records of the nature of diseases, placing great emphasis on "syndromes." It meticulously documents "prescriptions" and "dosage adjustments," offering a vivid and immersive experience.
