Introduction to Pearl Pool: The pool is shaped like a bottle gourd, about five meters long, about 1.5 meters wide, and 3.5 meters deep at its deepest point. The most amazing thing about it is that the water bubbles raised by the water entering the pool are large and small, thousands of them, layer upon layer, endless. Against the background of the green and clear spring water, they look like silver and look like pearls. . This is a rare sight in the world.
