The Natural Cave has once been called the Immortal Cave. The cave goes from the east to the north. It is 1,560 meters deep. There are all kinds of cliffs and fallen rocks. In the laneway on the underlayer of the cave which is 30 to 40 meters long, there are many stalactites with all shapes: standing towers, mushrooms, large pink stone lotus, breasts, fresh and tender bamboo shoots in spring, and twisting roots of the old trees. The further you go, the more stalactites you will see. Sometimes you even have to enter sideways, or stoop down to pass. People may wonder at the natural beauty here which is maintained so perfectly.
According to the Records of the Historic Sites in Zhanyi Zhou, a book written in the year of Guangxu in the Qing Dynasty, there were stone buildings and stone figures of Buddha in the cave. People did not know how deep it was, and named the cave Natural. There was also a Natural Basin. In the sixth year of Qianlong in Qing Dynasty (1741 AD), Wang Yumo, under the guidance of local people, entered into the cave and enjoyed the wonders in it.
