郭璞
Guo Pu (; AD 276–324), courtesy name Jingchun () was a Chinese historian, poet, and writer during the Eastern Jin period, and is best known as one of China's foremost commentators on ancient texts. Guo was a Taoist mystic, geomancer, collector of strange tales, editor of old texts, and erudite commentator. He was the first commentator of the "Shan Hai Jing" and so probably, with the noted Han bibliographer Liu Xin, was instrumental in preserving this valuable mythological and religious text. Guo Pu was the well educated son of a governor. He was a natural historian and a prolific writer of the Jin dynasty. He is the author of "The Book of Burial", the first-ever and the most authoritative source of feng shui doctrine and the first book to address the concept of feng shui in the history of China, making Guo Pu the first person historically to define feng shui, and therefore, Guo Pu is usually called the father of feng shui in China.
