Introduction to Nine Bends and Eighteen Bends: The windings have wonderful scenery, and the bays have weather. Where the water flow is gentle, it is as calm as a mirror, and everything is silent. Where the water flow is rapid, there are sounds. Some places are like beads falling on a jade plate, some places are like the sound of harps and harps, and some places are like the golden wind passing through the forest. It makes people feel relaxed and happy. Don't want to go home.
