from generation to generation, inheriting family studies, focusing on pharmacology and pharmacology. He attaches importance to clinical practice and advocates innovation. Since 1565, Li Shizhen has been collecting medicinal specimens and prescriptions in Wudang Mountain, Lushan Mountain, Maoshan Mountain, Niushou Mountain and Huguang, Anhui, Henan and Hebei, and visiting fishermen, woodcutters, farmers, coachmen, pharmacists and snake catchers. From fishermen, he has acquired knowledge of aquatic animals such as fish; from hunters, he has learned knowledge of birds and wild animals; from woodcutters. There, he learned the knowledge of elm, cypress and other plants; from farmers, he learned the knowledge of distinguishing grain.At the same time, more than 800 kinds of medical books and related books were consulted. He checked the medical books he read one by one. Sometimes he took some poisonous drugs personally to identify and verify the drugs. He corrected some mistakes in the names, varieties and origins of traditional Chinese medicine books in ancient times, reduced some tragedies between doctors and patients, and collected and sorted out the folk discoveries since Song and Yuan Dynasties. Many medicines and partial prescriptions enrich the contents of medicine. Referring to 925 kinds of books on medicine and other fields in past dynasties, we recorded tens of millions of words of notes and made clear many difficult problems. After 27 years, we changed our manuscripts three times. In the eighteenth year of Ming calendar (1590), we completed the 192 million-word masterpiece Compendium of Materia Medica. In addition, we also studied pulse science and eight strange meridians.
Li Shizhen has compiled such famous works as Compendium of Materia Medica, Book of Eight Veins of Strange Meridians and bin hu mai xue. Especially the outstanding contribution of Compendium of Materia Medica to world medicine is called "Medicine Sage" by later generations.
