Introduction to the Nine Dragon Monument: Located in Huiguang Temple, it is 2.7 meters high and 1.3 meters wide. It is carved with nine dragons flying through the sea of ​​clouds. Except for the one in the middle, the other eight are symmetrically distributed on the left and right sides. The head, body and tail of each dragon can be carefully distinguished. The dragon's mouth also contains an orb that can be rotated without falling out. The implication is that Dayu and the river dragons will subdue the people, and the nine rivers in the world will lead to the sea. From now on, there will be no flood disasters in the world, benefiting all people. The second meaning is to unify the country and the country.
