Introduction to Ring Waterfall: Ring Waterfall, “Guda Piao” in Miao language. The surging water of Donia Falls in the upper reaches flows down from the cave at the top of Dafengchongqunniao Mountain. The spring flow divides on the mountainside. A large spring water pours down from the high mountain and hits a huge boulder about 2 meters thick. The huge boulder was impacted into an arc with a diameter of more than 3 meters and a width of more than 3 meters. Water flowed through the arc, forming a waterfall and deep pool. The spring water in the pool is green and translucent, like emerald, and the mist is steaming, which is wonderful.
