Purple Glow Rock, also known as Chonghua Rock, is an underground karst cave. The cave is divided into inner rock and outer rock. The rock at the entrance is majestic. In the cave, there are wind tunnels, rain holes, thunder holes, the Bayin Hall, and stalactites, which are famous for their large size and exquisiteness. The outer rock is broad with a bright purple roof. When the sun rises and shines on the roof, there will be purple air hovering around it, thus the name Purple Glow Rock.
