Sun Simiao (58 1-682), Han nationality, was born in Jingzhao Huayuan (now Yaozhou District, Tongchuan City, Shaanxi Province) in the Northern Zhou, Sui and Tang Dynasties, and was praised as the "King of Medicine" by later generations. He is also a high-ranking Taoist figure, and his Taoist name is wonderful to real people. In many Taoist temples, there is a "Medicine King Hall". He has a noble medical ethics, attaches importance to health preservation and helps others. He is a real Taoist. He is from Yaoxian County, Shaanxi Province, China. 58 1 was born in a poor peasant family. He was very clever since he was a child and was highly praised by his teachers. When he grew up, he began to like Taoism. Due to the social unrest at that time, Sun Simiao lived in seclusion in Taibai Mountain, Qinling Mountain, Shaanxi Province, and gradually gained a high reputation. At that time, the imperial court appointed Sun Simiao as Dr. imperial academy, but he refused. In Taibai Mountain, Sun Simiao studied Taoist classics and explored the art of health preservation. At the same time, he also read many medical books and studied ancient medical prescriptions. He chose to "heal the wounded and rescue the dying" as his lifelong career. In order to understand the characteristics of Chinese herbal medicine, he traveled all over the mountains.
Sun Simiao also attached great importance to the folk medical experience, constantly accumulated interviews and recorded them in time, and finally completed his immortal book "Thousands of Money". After the establishment of the Tang Dynasty, Sun Simiao began to accept the invitation of the imperial court and cooperate with it to carry out medical activities. In 659 AD, the world's first national pharmacopoeia, Tang Xin Materia Medica, was completed. Sun Simiao died in 682 AD. According to historical records, materia medica, Taoist collections and other documents, as well as the inscriptions on Yaowangshan Mountain in Yaoxian County, Shaanxi Province, there are more than 80 kinds of Sun Simiao's works, many of which have been lost to this day. The Book of Old Tang Dynasty mentions Sun Simiao's self-interpretation of Lao Zi and Zhuang Zi. Since the Tang and Song Dynasties, the historical records of the two books have not been recorded and have been lost for a long time, so their views on Taoist teachings are unknown. Only Mr Meng's Notes on Laozi in the Forty Ancient Notes of Jin and Tang Dynasties were lost by Sun Simiao according to the sentence "The Valley God is immortal" in Chapter 6 of Zhao Bingwen's Notes on Laozi.
