Geographical position: The entrance of the cave lies in a smaller collapse doline which is located on 1720 metre above sea level, NW from the Xingchang village, on slope above karst polje.
Basic data about the cave:
Length: 541m
Depth: 99m (between highest and low- est points of the cave)
Horizontal length: 510m Stretching in E-W direction: 330m Stretching in N-S direction: 90m
Description of the cave:
On the bottom of the collapse doline with diameter of 20 m are two entrances, one of the eastern longer passage and the other of the shorter western passage (Fig. 2.5.5.).
Eastern passage:
The narrow and low entrance in the east- ern passage becomes after few metres widely opened and follows the bedding plane parting dip under the inclination of 200. In this part numerous fossils (especially crinoid stems) jut out of the weathered cave walls. At the beginning ceiling is lower than 1m, but highness of the passage monoto- nously increases and after 100m passes into largest hall in the cave (50X40X20m). On the bottom of the hall is an entrance that leads into series of short vertical steps that end (continue) with narrow muddy chan- nel (unmeasured) 30m below the hall. Channel is already bellow the level of the flooding waters.
The hall is on the eastern side break off with flowstone barrier. Up to 10m high and up to 25m wide passage is covered with flowstone and proceeds towards NW from the hall. After 100m channel turns towards SE and continues with flowstone slope. At the bottom of the slope is the most remote and the deepest measured point of the cave. The final parts of the cave are beautifully decorated by numerous and various forms of flowstone.
Western passage:
Western passage is developed along ver- tical E-W oriented fissured zone. Ten metre high entrance is triangular in shape and the walls diverge into fissure on the roof. The passage steeply descend toward W under the inclination of 350. The bottom is cov- ered by gravels and the walls are bare.

Analyse :
Members of the Karst Research Institute ZRC SAZU, Postojna, and members of the Yunnan Institute of Geography and Institute of Geology of the Chinese Academy of Sciences gathered the results of karstological researches of south Chinese karst in two projects adopted by an agreement on scientific and technological cooperation between the Government of the Republic of Slovenia and the Republic of China. The projects Karst Environmental Protection and Exploitation of Cave Resources and Study of Stone Forest Genesis, Function and Structures of the Underground Karst Aquifers in Lunan, Yunnan Province were going on from 1995 to 1997. They were made feasible by the Slovene and Chinese Ministry of Science and Technology and supported by Yunnan Provincial Science and Technology Commission, Administration of Stone Forest, and The Ninth Township Scenic Spots and Historical Sites Administrative Bureau, Yiliang County. The researches were carried out near Liupanshui, the western part of Guizhou, in karst between the mountains in Guizhou and Yunnan Plateau, in the area of Lunan stone forests and in cone-karst at Xichou, Yunnan.
