Introduction to Wolongtan: It takes about ten minutes to reach "Wolongtan". It is impossible to verify whether there was a dragon lying in this pool originally, but from all directions of the pool it is indeed an ideal place for hiding dragons and crouching tigers. Looking up, the pool wall is 8.5 meters high, with a clear water cascading down. The climbing plants on both sides are lush and green, forming a blue dragon that has been sleeping for thousands of years in the pool. Due to the water infiltration, the rock on the left wall vaguely shows a 2-meter-high "dragon" character. Wolongtan also got its name from this. The 10-square-meter empty space on the right is said to have been the place where Wu Sangong, the originator of shiitake mushrooms, rested on a rainy day.
