Xianghongdian Reservoir (National Water Conservancy Scenic Area), located in Jinzhai County, Lu'an City, Anhui Province, is located in the upper reaches of the Xiqiao River, on the bank of Qiyun Mountain. A lake is clear, green, the mountains are green, and the nephews are reflected in the water. With the ripples of the water, the ripples are trembling, the mountains are intermingling, and the landscape is very beautiful. On the Dangzhou Lake, the tea garden on Qiyun Mountain floated a burst of tea. Driving the boat around a mountain, driving into a bay lake fork, thousands of acres of bamboo sea raised layers of green waves. A small mountain appeared in the heart of the lake, similar to a girl's mirror grooming. From this, it was Zhang Chongkongyan, who had been here, knew that there were two famous waterfalls nearby; one was a magnificent and famous pound-eyed, and the other was a poetic Longtan.
