Yaowang Mountain has five peaks that are distributed like fingers. It was called "Wutai Mountain" in ancient times. It was renamed "Yaowang Mountain" because Sun Simiao, a great medical scientist in the Sui and Tang Dynasties who was revered as "King of Medicine", once lived in seclusion here. It is located 1.5 kilometers east of Yaozhou District, Tongchuan City, Shaanxi Province. It is located in the border area between Guanzhong Plain and Weibei Plateau. It has typical northern hilly and canyon landforms, towering ancient cypresses, magnificent palaces, numerous steles and stones, and beautiful scenery. It has been listed as the first batch of national key cultural relics protection units. The Yaowang Mountain Temple Fair was created to commemorate Sun Simiao. In the Northern Song Dynasty, the commemorative activities were held in Nan'an Jingming Palace. During the Jiajing period of the Ming Dynasty, the central Taoist temple for sacrifice began to move to Beidong. According to the "Food Donation Stele Record" in the 11th year of Shunzhi in the Qing Dynasty (1654), when the Yaowang Mountain held a temple fair, "the Qin people, men and women, young and old, the sound of people and horses continued all night, and it lasted for more than a month. Even the princes and scholars did not go up to worship." From the late Qing Dynasty to the Republic of China, the duration of the Yaowangshan Temple Fair was changed to ten days, starting from the second day of the second lunar month, the sixth day of the first lunar month, and ending on the eleventh day. During the temple fair, bells and chimes rang, drums and music were loud, and there were performances such as "roadside lanterns", lions, dragon lanterns, fireworks, and "Dawn Opera". Tens of thousands of people gathered from all directions, and the atmosphere was extremely lively. At the climax of the temple fair, the streets were deserted. The Yaowangshan Temple Fair promoted the medical ethics and style of Medicine King Sun Simiao, promoted the inheritance and development of the traditional Chinese medicine culture of the motherland, and has research value in folklore, sociology, and Shaanxi local culture.
