Poetry and prose collection by Tao Hongjing, written in 499 CE
The Zhengao (真誥, Declarations of the Perfected) written in 499 CE is the Shangqing Daoist patriarch Tao Hongjing's comprehensive collection of poetry and prose from the original "Shangqing revelations", which were supposedly given to the mystic Yang Xi by a group of Daoist zhenren Perfected Ones from 364 to 370. This classic text has long been famous both as a foundational text of religious Daoism and as a brilliant exemplar of medieval Chinese poetry.
