Introduction to Tiande Cave: Tiande Cave, also known as "Dog Chuan Cave", is located about 80 meters above the entrance of the Ganzongzao water outlet. This cave is shaped like the bottom of a pot, about 200 meters in diameter, with cliffs of 100 feet on all sides and hanging vines hanging upside down. According to legend, in ancient times, the entrance to Tiande Cave was very small, covered with trees, brambles, and strong grass, and no one discovered it. Later, some people came here to hunt. The hunting dogs chased the hedgehog into the hole. The hunter followed and jumped in, only to reveal the secret of the hole, so it was called the dog hole. During the Republic of China, Huang Yuedong and Huang Yunzhong built villas at the west foot of the "big tiankeng" in the cave. County officials and celebrities often visited this cave. They thought the name "Gou Chuan Cave" was inappropriate, so they changed it to "Tiande Cave". So far, the people call it both names.
