The 128 karst caves are distributed in the strata of the five ages of Cambrian, Ordovician, Silurian, Permian and Triassic and are the karst cave group with the largest number of parent rock geological ages in the world.
A total of 20,000 square meters of the caves are open to visitors. The Longhu, Lion, Building, Red Fish, Immortal, Fairy, Songjia and Zhongfeng caves are each more than 2,000 meters long.
Some of the biggest crowd-pleasers are the oldest stalagmite (the things that hang down) nicknamed the Leaning Tower of Pisa, Stone Curtain and Buddharupa in the Lion Cave.
The oldest stalagmite looks like the white marble pillar in front of Tian'anmen Square in Beijing.
Stalacto-stalagmite is a cylindrical object formed by opposite growth and docking of stalagmite and stalactite. A stalacto-stalagmite in the cave produces the tilted shape due to subsidence, and in turn producing the name Leaning Tower of Pisa.
