The so-called four hundred years of Xia Dynasty are actually three dynasties, the former Xia, the poor dynasty and the later Xia. The former Xia Dynasty was China's first slavery dynasty. Taikang lost moral integrity and was overthrown by Hou Yi's revolution, establishing a poor dynasty. At that time, people believed that the death of Yu and his usurpation were accidental, and they demanded the restoration of the virtues of the late primitive society. But society has advanced, and it is inevitable to enter a slave society. This is the root of Hou Yi's tragedy.
Hou Yi was not killed by Han Yun, but by the remnants of the former Xia nobles in cruel revenge. Hanzhuo and Chang'e jointly attacked the remnants of the former Xia aristocracy. The poor dynasty flourished. This is also the product of the great division of mental labor and physical labor. Due to the one-sidedness of people's understanding, private concepts are once again bred and produced. Hanzhuo's son, who had made great achievements, became the king of slavery, which eventually led to the collapse of the poor dynasty. Starting from the Later Xia Dynasty, the new dynasty launched a slanderous attempt to completely obliterate the Shengqiong Dynasty and put the crime of killing Hou Yi on Han Yun.
