Dayu married during Dayu's flood control process.

It is said that Emperor Yao appointed Yu to control the water. After accepting the experience of his father Gun's failure to control the water, Dayu realized that blocking was not as good as sparse, and led the people who controlled the water all over China. Unconsciously, Dayu was already 30 years old, and Dayu had never married in order to control the water.
That is, in the process of water control, Dayu passed by Tushan in Haozhou, Anhui (now in Huaiyuan County, Bengbu City), and met the daughter of the Tushan family. On a warm spring day, a pair of pure men and women met in the green mulberry forest. It can be said that they fell in love at first sight and became husband and wife. However, Dayu had to run around to control the water, so he could only temporarily become the door-to-door son-in-law. The female jiao still lived in his own home. However, Dayu led the water control team to leave on the fourth day of marriage because of the heavy responsibility of water control. During the later water control period, the story of "three times without entering the house" also happened.
