The deepest and largest natural well on earth is called Xiaozai Tiankang. It is located in Penji, in the heart of China. This amazing well is completely natural and reaches a depth of 662 meters, a length of 626 meters and a width of 537 meters. But what stands out the most is the explosion of life it inhabits.

Xiaozhai Tiankang is what geologists are confused about due to the influence of water. In this case, it was created on top of a cave with an underground river of 8.5 kilometers in size and flowing into a spectacular waterfall. Its enormous size makes it the deepest sinkhole in the world.
It houses close to 1,300 species of plants and wild animals. Among the most fascinating "tenants" that roam their underground forest, the misty panther stands out
Locals have known him since ancient times.
