Introduction to Haitian Cave: Haitian Cave is the largest of the seventy-two caves. Because it was built by the eminent monk Wuwu, it is also called Wuwu Cave. At that time, the eminent monk Wu Wu removed the silt between the stone cracks, dug through the related caves, connected the Haitian Cave with the small caves above and below, and built the Zhaohai Pavilion on the top of the cave. Looking down from the pavilion, you can see the peaks standing in the distance on all sides, the greenery hitting your face, and the fragrance of flowers, making you feel like you are in a fairyland.
