Introduction to Huafeng Cave: Under the Huafeng Cave beside the "Xiandu Bridge", there is an ancient cave with a hall height of 4 meters and a length of 8 meters, called "Huafeng Cave", also known as "Dongshan Stone Chamber". In the fourth year of Xuanhe of the Song Dynasty (AD 1122), a natural cave temple was built. The couplet "There is sky in the cave, there is a cave in the sky; there is no scenery outside the mountain, and there is no mountain outside the scenery" is carved on the huge stone at the cave door. The statue of Guanyin later became a chanting place for spiritual monks.
