One of the ruins of Yao Wang Shan today is the Bazaar Cang (Tibetan Medical College), also known as Yao Wang Temple because of its religious nature. Sakyamuni can cure all kinds of diseases. According to legend, the King of Medicine is an incarnation of Sakyamuni Buddha. Since the emergence of Tibetan medicine among Tibetan people during the Tubo Dynasty, this ancient knowledge has been spreading for more than 1000 years. In the 7th century, when Princess Wencheng married Tubo, she brought Chinese culture from the Tang Dynasty. Among them, a Chinese medicine book was called "Medical Complete". Since then, Princess Jincheng remarried to Tubo and brought a medical book "Yuewang Medicine Diagnosis" to make some theories and methods of traditional Chinese medicine gradually merged into Tibetan medicine.
