The stalactites in the cave are many cool animals, including the crocodile hall, the golden chicken hall, the beast hall and the rhino hall. There is a bell in the cave, such as a bronze bell, which is fastened to the ground, and the bell body is covered with fine stone milk, like a scripture. People say that this is the "law" of the animal world, so the bell name is "Tianzhong", and the name of the cave is also derived from it. The moisture in the hole is very heavy, the body feels cold, and you have to wear more clothes to enter the hole.
