Renowned Taoist immortal during Eastern Han dynasty
Yin Changsheng (陰長生, "Long-life Yin", fl. 120-210) was a famous Daoist xian ("transcendent; immortal") from Xinye who lived during the Eastern Han dynasty (25-220 CE). After serving more than ten years as a disciple of the transcendent Maming Sheng ("Horse-neigh Sheng") he received the secret Taiqing (太清, "Great Clarity") scriptures on Waidan ("External Alchemy"). Several extant texts are ascribed to Yin Changsheng, such as the Jinbi wu xianglei can tong qi (金碧五相類參同契, "The Five Categories of Metals and Minerals in the Cantong qi").
