The Great Flood of Gun-Yu, also known as the Gun-Yu myth,[1] was a major flood in ancient China that allegedly continued for at least two generations, which resulted in great population displacements among other disasters, such as storms and famine. People left their homes to live on the high hills and mountains, or nest on the trees.[2] According to mythological and historical sources, it is traditionally dated to the third millennium BCE, or about 2300–2200 BCE, during the reign of Emperor Yao.
However, archaeological evidence of an outburst flood at Jishi Gorge on the Yellow River, comparable to similar severe events in the world in the past 10,000 years, has been dated to about 1920 BCE (a few centuries later than the traditional beginning of the Xia dynasty which came after Emperors Shun and Yao), and is suggested to have been the basis for the myth.[3]
Treated either historically or mythologically, the story of the Great Flood and the heroic attempts of the various human characters to control it and to abate the disaster is a narrative fundamental to Chinese culture. Among other things, the Great Flood of China is key to understanding the history of the founding of both the Xia dynasty and the Zhou dynasty, it is also one of the main flood motifs in Chinese mythology, and it is a major source of allusion in Classical Chinese poetry.
