Huangdi Neijing Tai Su, simplified Tai Su, also known as Huangdi Tai Su. It was compiled by Yang Shangshan, a physician between Sui and Tang Dynasties. Tai Su in Huangdi's Internal Classic is a biography of Huangdi's Internal Classic (volume 18), with a total of 20 articles, the titles of which are Birth Outline, Yin and Yang, Human Harmony, Tibetan House, Meridians, Acupoints, Camp, Stephy, etc. Typhoid fever, cold and heat, pathogenic factors, wind, qi and miscellaneous diseases. At the beginning of the Tang Dynasty, the court ordered Yang Shangshan to preside over the collation and revision of ancient medical books. On the basis of the original 20 volumes, Yang expanded the book Tai Su, which was once lost after the Southern Song Dynasty, to 30 volumes. However, Tai Su was soon published and introduced to Japan. At the beginning of the 9th century, Tai Su, an ancient version of Japanese Ningna Temple, was discovered one after another, which attracted the attention of China scholars. From the sixth year to the tenth year of Guangxu (1880 ~ 1884), Japanese scholar Yang Shoujing (Xing Wu) returned from a visit to China and made textual research, annotation and collation on the book. The existing Tai Su has some incomplete contents, and the photocopy of Japanese Toyo Rare Medicine Series 1987 is the best version. The popular version in China is the blue version photocopied by Xiao Yanping, People's Health Publishing House 1955.
Tai Su is an early work that classified and annotated Huangdi Neijing. The original text of Neijing quoted in the book is the closest to the ancient appearance among the existing medical books, and the lost articles of many classic medical books have been preserved, which can be used to collate Suwen and Lingshu today, which has high reference value for studying Huangdi Neijing.
