Xu Zheng (Eastern Wu)

Xu Zheng (fl. 200s) was an Eastern Wu official who served as the "Taichang (太常)" and a Daoist author of the "Three Five Historic Records" (, literally: "Three Five Calendar") and Wuyun Linian Ji. The "3-5" refers to the "Three August Ones and Five Emperors" (三皇五帝).

Xu Zheng relates two different variants of the creation myth of Pangu.
