The three-fold waterfall in the mouth of the bowl kiln is composed of three layers of upper, middle and lower layers, and has a rhythm of hanging waterfalls. It seems that a large and white Hada floats in the mountains, and the sound of the water is on the other side of the mountain. Can hear the vagueness. As you approach the foothills, the panoramic view of the waterfall is unobstructed. The waterfall is about 40 meters high and about 6 meters wide. The water sprays the beads and splashes the jade. It falls down and merges with another turbulent flow from the mountain to collect it in a Bitan. Stirring is like a sieve of rice. On the water surface, countless water beads are like the rice grains in the rice sieve, and they are excited to roll and beat. This lake, the locals vividly call it "Mi Si Tan". Under the squeezing of the upper stream, the pool water spewed out along the mouth of the lake, and slid into the next pool. The water flow was more grand, forming a second-fold waterfall with a wider and more rapid flow. The fold was natural and rhythmic, and the water flow was invested. A green water pool; the water crowded in the water pool spewed out again, rushing down the cliffs of more than 40 meters high, forming a third-fold waterfall, falling straight into the Bitankou, about 15 meters below the cliff. When the water is stirring, the silver beads are splashing, and the splashing water drops fall into the water pool, the ping-pong sounds, forming the spectacle of "big beads and beads falling into the jade plate."
