Wude Tiankeng in Zhenxiong County, Yunnan, is a pure natural landscape and a wonder of nature. Compared with other tiankengs in China, it has its own merits, not in depth, but in breadth and natural landscape inside the tiankeng. Because it is located in the Wumeng Mountain area of Yunnan and Guizhou, transportation is inconvenient. With a little development and promotion, it can be a famous scenic spot. The most interesting thing is that there are still residents living inside, just like the Jueqing Valley in martial arts novels, living a paradise life, lush and green, chickens, dogs, geese and ducks, full of life. There are also pure natural karst landforms inside, with huge stalactites and ingenious craftsmanship, which is worth a visit.
