Fu Xi
The Chu Silk Manuscript, which is an ancient Chinese astrological and astronomical text from the southern state of Chu, was discovered by grave robbers in a (ca. 300 BCE) Warring States period tomb east of Changsha, Hunan Province. Although this text does not mention "Yubu", the "Seasons" section records a deluge myth about the siblings Fu Xi and Nüwa being the only survivors of the Great Flood and their children "bu" "stepping" to calculate time and seasons.
