Introduction to Shuiliandong: Located behind Longwang Bridge, it presents a natural cave hidden behind Yilian Waterfall. Many lifelike stone monkeys are playing happily outside Shuiliandong. Lying or standing, the postures are different and full of interest. There is a crystal waterfall next to the Shuilian Cave, which overflows from the stone wall. Because there are many crystals on the stone wall, they sparkle under the light, hence the name.
