Wash the body hole, Huanglong's second step, an outlet of ancient glaciers. The cave is located at the bottom of a 40-meter-wide calcified wall, about 1 meter high,1.5 meters wide, and 1 meter wide. It is full of light yellow and milky stalactites. The water mist at the mouth of the cave filled with waterfalls like a curtain. The legend is that the fairy cleans the body, and the sterile women enter the hole to wash their bodies and enjoy their precious son.
