Introduction to Kesang Cave: The proven part of Kesang Cave is nearly 3 kilometers long, with different widths. The widest part is 18 meters, and the narrow part can only allow people to crawl through. There are a large number of moonstone deposits in the cave, which vividly reflect the changes in the local climate during the Quaternary Period. The various colorful and bizarre scenery in the cave can be called a "dream world" and are of high ornamental and scientific research value.
