It is a worthwhile trip, it may restore popularity after the epidemic, so we now go to the ticket is 50% off, including skiing boats into the hole and taking the cable car. The cave is very large. It is the largest group of stone bell milk caves I have ever seen. There are also rivers below and transparent fish in the river. It is only rarely seen recently. The river in the underground river is very clear and the cave is very cool. This is also one of the places where Xu Xiake walked! Worth a visit, recommended push
