Introduction to Jiuding Square: Dayu unified the tribes while controlling the water, connected the territory controlled by the tribes into a whole, divided them into nine states, and each cast a tripod to symbolize the nine states. In the middle of the square, there is a huge bronze sculpture of Dayu reading the Nine Tripods. Dayu rides on a dragon carriage, facing the Yangtze River, echoing the Nine Tripods carried by nine beasts. It is the core and soul of the mythical garden. On both sides of Jiuding Square, there is a drum for admonishment. It has a strange appearance, with four legs and four wings. Dayu set up the drum to listen to the voices of the people. There is a record in ancient books that "Yu set up admonishment drums in the dynasty". Hearing the sound of drums, Dayu immediately came out to receive him. He did not avoid the cold in winter or the heat in summer.
