Introduction to the Queen Mother Curtain: The Queen Mother Curtain is a screen formed by stalactites in the cave. There are exquisite water lines on the surface. Each small shining water droplet seems to be threaded. At first glance, it looks like a jade bead curtain. Legend has it that the Queen Mother's seven daughters often went to Longtan to bathe. The Queen Mother followed them every time and stood in front of the screen to monitor to prevent the fairies from stealing the mortal world. The cave is full of stalagmites, stone flowers and stone curtains, which complement each other.
