Within this scenic area there is a dry cave and a flooded cave which experts confirm were formed around 1.4 million years ago.

The dry cave has a length of some 1.5 kilometres of which so far only around 510 metres have been explored. Within its interior there are stalactites, stalagmites, stone pillars, stone flags, stone waterfalls, tongues of stone, curled emery stones, aragonite flowers and single crystal calcite flowers. All of these are extremely ornamental and of great interest since the shapes of the curled emery stones at present has no scientific explanation. Experts praise the stones as national level rock articles since aragonite flowers and single crystal calcite flowers are rarely seen either at home or abroad.

The flooded cave is three kilometres long and at the present time about 250 metres have been explored. At its deepest point, the water in the cave is seventeen metres deep with a cave width varying between three and fifteen metres. The interior of the flooded cave has a peculiar shape with a huge stalactite joining the apex of the cave to the floor. This is similar in appearance to the mythical Dragon King of the Eastern Sea’s heavenly needle. In the subterranean river also dwells the extremely precious national level protected Chinese giant salamander (Andrias davidianus). Nothing more beautiful can be imagined than a tour by boat through the cave which is just like the Dragon King’s Palace!
