First, the Xia Dynasty exists in ancient books. In early summer, Dayu was in charge of water control. Because of Dayu's outstanding achievements, it opened up an era of drought and little rain for the world, and Shun Di had to give way to Dayu, so Dayu became emperor. After Dayu's death, his son didn't get the throne, and the throne was taken away by Xia Qi. He began to rule the Xia Dynasty. Later, after Xia Qi's death, his son didn't know how to safeguard political rights, and the Xia Dynasty was later ruled by Hou Yi.
