Fang You-zhi, courtesy name 中行, number Jiulong Shanren. A native of She County, Anhui Province in the Ming Dynasty. Fang You-zhi He said that he was blunt by nature, "foolish compared to Confucianism and afraid of not being able to do it." He did not study medicine at the beginning. Later, in middle age, he lost his wife twice due to common cold and five times due to infantile convulsion After losing his son, he set out to study medicine, and he especially has experience in treating diseases caused by cold. He believes that Shanghan Zabing Lun is a master who has mastered the art of medicine for centuries. When the Western Jin Dynasty Wang Shu-he was reorganized, some changes were made; and the Jin Dynasty Cheng Wu-ji made annotations, many changes were made, resulting in Those who practice medicine may write incomplete books without practicing, or they may follow the mistakes of the two schools of medicine and lose the truth. Therefore, I spent more than 20 years traveling to Qi, Shandong, Sichuan, Shaanxi and other places, visiting teachers and friends, and exploring the true meaning of disease caused by cold. When he was old and returned home, he "returned to his fields and closed the pavilion, and studied the differences between Li and Li, and revised them after returning to divorce." After eight experiences of cold and heat, he revised his manuscript seven times and wrote Shanghan Lun Tiaobian in eight volumes, followed by " Materia Medica Chao", "You Wen" and "Ji Shu" each have one volume.

Fang You-zhi revised and revised Shanghan Lun by adopting the method of whole movement and deletion, and carried out overall revision and editing. He divided the articles on taiyang disease into volumes one, two and three, yangming disease and shaoyang disease were combined into the fourth volume, taiyin disease, shaoyin disease and jueyin disease were combined into the fifth volume. The articles on dampness disease, rheumatism, Zabing, as well as articles on cholera, yin-yang transmission, and post-departure labor recovery are combined into the sixth volume. It is considered that the chapter "Distinguishing Syndrome of Spasm and Dampness" is still credible, and it is considered that the two chapters "Methods for Identification of Pulse" and "Methods for Normal Pulse" contain part of the original book content, and are combined into "Methods for Identification of Pulse", which is the seventh volume. Wang Shu-he compiled the articles on the permissibility and inadmissibility of sweating and placed it in the eighth volume. The Taiyang (EX-HN5) chapter has the biggest changes in the entire book. He believed that the evils of wind and cold invaded the human body's nutrient-defense. The wind controls the defense, so the articles about illness caused by apoplexy of the body are compiled into the first volume, and the articles about disease caused by cold hurt the camp, so the articles about illness caused by the camp disease caused by cold and the words "disease caused by cold" are compiled into the first volume. It is the second volume; at the same time, the provisions on wind and cold violating nutrient-defense at the same time are compiled into the third volume. These are the three types of exogenous wind-cold that he advocated. His examination and editing of the articles of Shanghan Lun are indeed innovative, which enhances the systematicness and orderliness of the original text, especially reflecting his rich practical experience and theoretical understanding of disease caused by cold. Later, it was vigorously advocated by Yu Jia-yan and summarized as the theory of "three cardinal principles". Harmony emerged. Famous masters in the Qing Dynasty such as Zhang Lu, Yu Jia-yan, Wu Yi-luo, Zhou Yang-jun, Huang Yuan-yu, etc., They all supported his theory and formed the famous disease caused by cold theory called the Wrong-Jiang-Re-Revision School, also known as the "Wrong-Jiang School".
