Introduction to Damo Ladder: The steps are 3.5 meters wide, smooth and well-proportioned, and 92 meters high, very spectacular. When tourists climb up the Damo Staircase, they will make a crisp sound every time they step on a step, one sound louder than the other. The sound echoes back in the valley, like the sound of knocking wooden fish or the chirping of golden frogs, which is very novel.
