Introduction to the stone niche: After passing through the deep, winding, bead-like deep pool, there is a stone niche of more than 50 meters in the middle of the lower section. The niche is small at the top and large at the bottom, shallow at the top and deep at the bottom. The bottom of the niche can accommodate more than a hundred people. A silver curtain fell from the top of the niche, scattering beads and jade, floating in the sky, as if from heaven, and drunken the gods in the sky. This is the story of the gods riding in the mortal world privately, enjoying the family relationship in the world.
