Introduction to ancient trees: There is an ancient banyan tree in the north and south of the courtyard dam that is believed to be more than 1,700 years old. The crown of the tree covers the entire courtyard dam. At the bifurcation of the trunk of the ancient banyan tree in the north, there is a small temple about two feet square in the center, dedicated to "Huang Ge Daxian". Legend has it that all you need to do is touch the tree. That is to say, it can cure diseases and eliminate disasters. The ancient banyan tree in the south has tangled roots and tightly wraps a small earth temple. These two ancient trees, the tree that rides on the temple and the tree that wraps the temple, are unique in the world.
