Introduction to Tangyin Waterfall: The waterfall formed by the spring water lasts all year round. It is a pleasure to watch, the sound of the water is pleasant, and it looks like thousands of dendrobium pearls pouring down. The ground was dug into a pond and koi fish of different colors were raised there. Visitors gathered there and elegant scholars chanted them, so it was called "Watching Fish at the Silver Waterfall" and it became one of the new sights of Pearl Spring.
