Where was Dayu born (in today's Shandong)? What special functions does he have?

So a national hero who has made great contributions in many aspects is deeply admired by people, so there are many myths and legends about him. Yu's birth is full of mystery. It is said that Gun stole the emperor's treasure "evil soil" in order to control water disasters. The emperor was very angry and ordered the Vulcan Zhu Rong to kill the gun in the feather suburb. The gun died for three years, but his body didn't rot. Someone cut open his stomach with a knife and Yu jumped out, while Gun himself turned into a yellow bear and hid in the mountains.

Yu inherited his father's will and began to control water. Because of busy work, I am not married at the age of 30. At this time, a white fox with nine tails came, and he was deeply impressed by his professionalism. She turned into a beautiful girl named Tu Shanshi, who sang to Jade to show her love. I married her. However, after marriage, he was still busy managing water and rarely went home to reunite with his wife. Miss Tu Shan went to the water conservancy site to look for him, but she just saw Yu turn into a bear and dug a cave. Tu Shanshi thought that Yu was really a bear, felt ashamed to marry a bear, and ran back. Jade chased after her, but forgot to change back to human form. Tu Shanshi became more pessimistic and disappointed when he saw a bear chasing after him, and turned into a stone. I shouted at the stone, "Give me my son back!" " The stone cracked and gave birth to a child, so Yu's son was named Qi.
