His life is powerful, and the tortoise under the stone tablet seat is his portrait. Legend has it that in ancient times, Baxia often carried three mountains and five mountains on his back and made waves in rivers, lakes and seas. Later, Dayu subdued it when he was controlling the water. It obeyed Dayu's command, pushed mountains and dug ditches, dredged rivers and made contributions to water control. After the flood was defeated, Dayu was worried that he would run wild again, so he moved to a huge stone tablet with indomitable spirit, which was engraved with the merits of water control and told him to carry it. The heavy stone tablet prevented him from walking casually. The dam is very similar to the tortoise, but there is still a difference when you look closely.
