Introduction to Black Dragon Pool: Due to the impact of running water falling from a rock wall over 10 meters high, the depth of the pool is unfathomable. Also, because of the pine trees between the walls, the pine roots are entangled in the rock crevices, bending or stretching. Brown scales, resembling a black dragon, appear on the edge of the pool, and the "dragon" body is reflected, presenting a magical landscape of "a dragon exploring the abyss in the Black Dragon Pool", so people call this pool the Black Dragon Pool.
