There are more than 20 large and small drops, and the largest drop is more than 20 meters. Along the way, the water flow may be fast or slow, and the surrounding environment is beautiful, with mountain springs alternating between fast and slow, pools stacked on top of each other, birds singing in the mountains, wild flowers blooming, willow branches on both sides of the bank, surrounded by green mountains, and everything is green as far as the eye can see.
