Introduction to Tianlu Chengrui: Tianlu Chengrui is located near Mituo Rock. They are two ancient trees hugging each other tightly. One is a Double Ninth Festival tree and the other is a banyan tree. The roots of the trees are intertwined and the bodies of the trees are hugging each other. The trees have been entangled like glue and paint for more than 300 years, just like a pair of loyal lovers, attracting many young and old people to take photos under this tree.
