The Diaoshuilou Waterfall is located at the northern end of the Jingpo Lake in mountains south of Ning'an County, Heilongjiang Province. The Jingpo Lake was called the Huhan Sea during Bohai Shire Period (698-926) of the Tang Dynasty (618-907), and later called Bi'erteng Lake, which means the lake is as tranquil as a mirror, in the Ming and Qing dynasties. As what it is called Jingpo (mirror lake), the water is crystal clear and tranquil like a mirror. During summer and autumn seasons, the lake takes on a fascinating look with mountains decorated with trees and flowers, birds hovering in the sky, fish jumping up and down in the lake, and the reflection of rocks and rosy clouds setting off each other.    

The Diaoshuilou Waterfall is at the outlet of the Jingpo Lake where lies a crack formed during the cooling of lava. The water pours down through the crack to a deep pool underneath, with a fall of over 20 meters high and more than 40 meters wide. The waterfall bursts forth white waves that shine with multicolored rays of morning or evening sunshine and gives out a thunderous sound. In winter, the waterfall changes into an ice curtain, hanging down from the cliff. To the east of the waterfall is a pavilion with guardrails and rocks, providing a good place for people to stand or sit while viewing the great spectacle.
