Introduction to Milk Flower Rock: Milk Flower Rock Cave is composed of stalactites of different shapes, like a natural cave, in which there is a pillar holding up the sky, and the roof of the cave is supported by the ground. There is a waterfall of more than 30 meters cascading down from the top of the cave. The trickling water inside the cave forms a curtain of water, which is like Penglai in a fairyland.
