Introduction to Immortal Cave: Immortal Cave is tens of meters deep. There is a grotto on the north side of the cave, and there is a stone Buddha statue in the cave. It is located on Qingshi Mountain, eight miles east of Zaozhuang Shiliu Garden City. It is said that Taoist Xiao practiced here and became an immortal. A waterfall cascades halfway up the mountain. Viewed from the bottom of the mountain, it looks like white clouds across the sky, hence the name "Xiandong Xuanyun". It was one of the eight scenic spots in Yixian County in ancient times.
