It was discovered by chance by the local people of that year. This reminds me of the Terracotta Warriors and Horses found in the Mausoleum of the First Emperor of Qin Dynasty, which is very large. Go down from a cave to level 70, turn around and change scenery step by step. Four main stalactites can be seen. There are also stalactites regenerated from broken stalactites. Some local people pondered for three years and developed the stalactite pipe organ. You can listen to a paragraph on the spot. There is also a church and a pool of wishes.
