Introduction to Tiannv Sanhua Waterfall: Tianlai Valley is the largest valley between streams in the scenic area under the Cailan River. Sound can be transmitted through the empty valley and the sound of nature can be heard, so it is named Tianlai Valley. The valley is surrounded by high cliffs. The sky is low and the clouds are close. A waterfall falls from the sky, fluttering like a goddess scattering flowers and blessing the world. What's even more amazing is that the waterfall has a musical rhythm. Every one or two seconds, it throws out pearl-like water splashes in circles, just like the rhythm of a fairy's flower basket picking flowers and tossing them. It's wonderful.
