However, archaeological evidence of an outburst flood on the Yellow River, comparable to similar severe events in the world in the past 10,000 years, has been dated to about 1900 BC (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]
