Introduction to Jade Crab Spring: Jade Crab Spring is located on Shicheng Peak next to Qinpo Stream on the northern slope of Yushan Mountain. Because of its mellow and clear water quality, it is known as "the first famous spring in Yushan Mountain". The spring is more than a hundred meters long and is in the shape of a floor. It becomes steeper as it goes up, and there are many strange rocks in the stream. The water is thick and contains a lot of minerals. Try placing an aluminum coin gently on the water and it will float without sinking. What's even more peculiar is that bubbles often appear on the bottom of the water, like crabs blowing foam.
