Introduction to the Pagoda Hall: Inside the cave, there are shapes such as pastoral fields made of stalactites, Guanyin Bodhisattva, Arhats and stalagmites, stone drums, stone tables, stone benches, etc., as well as poems written by literati of the past dynasties. The spring water from Xiadong surges out, clear, bright and quiet, and never dries up in all seasons, forming the Luanshan Dongjiang River.
