Wherever one turn is are small and large chunks of rock being continually pushed down stream. When piles of them block the way, the water spills in all directions, washing away the river banks. Hence, the earth and rocks, after becoming loosened, are continuously collapsing.
放眼所及，大大小小的碎石不斷由上游沖刷而下，堆滿河道，溪水無「路」可行，只得四處奔竄，淘洗兩岸山脈；如此又造成土石鬆動，不停惡性崩壞。
