The Quanpu Valley, also known as Laotanggou, was formed during the Cambrian period of 540-490 million years ago. After long-term water erosion, movement, and gravity collapse, the ancient planation surface at an altitude of 800-1200 meters was strongly cut down locally to form the geological wonders of the magnificent mountains, beautiful rivers, high peaks and turbulent waterfalls. The "Yuntai Heaven Waterfall" with a single-stage drop of 314 meters is located at the end of the Quanpu Waterfall. It kisses the blue sky and goes down to the stone shoal. It is like a galaxy flying down and jade column supporting the heaven magnificently. The Quanpu Valley is high and straight in the mountains, deep and turbulent in the water flows. Along the valley against the river, scenic spots such as the Quiet Pool, the Dragon-roaring Waterfall and the Porous Spring, will bring tourists into a fairy dreamland.
