Wei Boyang

Eastern Han Daoist alchemist traditionally credited with the Cantong Qi, revered as the 'king of alchemical scriptures'.

Also known as Hao Yunyazi

Wei Boyang, from Shangyu in Kuaiji, styled Yunyazi, is traditionally placed in the reign of Emperor Huan of the Eastern Han as a man of good family who declined office to cultivate the Dao. He is credited with the Zhouyi Cantong Qi, which uses the hexagrams of the Book of Changes and Huang-Lao thought to explain alchemy and self-cultivation, later revered by Daoists as the 'king of alchemical scriptures'. Most details of his life come from Daoist sources such as Ge Hong's Biographies of Immortals, and his exact dates cannot be confirmed.
