Introduction to Wahuang Grottoes: It is said that this place was where Nuwa made stones to mend the sky, and the traces of her digging into the mountain and taking stones can still be seen. The inscription on the left cliff is "Nuwa's Stone Refining Place" and the inscription on the right cliff is "Layered Mountains and Towering Green", both of which are works by famous people in ancient times. There is a 200-square-meter platform halfway up the mountain, and there are Wahuang Grottoes and Sanqing Cave on the side walls, both of which are natural stone caves. There are statues of Nuwa, maids and Taoist gods respectively enshrined inside. Among them, there are tall tree trunk fossils on the inner wall of Sanqing Cave. There are dozens of stone tablets outside the cave, describing in detail the reconstruction of temples in the Song, Yuan, Ming and Qing dynasties.
