The Lishui River is also known as Xining River, which refers to the important tributary of the Yellow River that flows north of Xining City. When spring and summer, the ice and snow in the upper reaches of the flood melted, the water source was sufficient, and the river flowed to the western suburbs of Xining, Beichuan River, and Nanchuan River, and the river flow rose sharply and choppy, so it was called "turbulent spring rise", one of the eight ancient scenes of Xining. The Lishui River is the cradle of the life of the people of the plateau that has been continued and reproduced for generations, and is also known as the "Mother River", which the local people call "Water of Life". As early as four or five thousand years ago, the ancestors of the plateau people reproduced and lived here, creating a splendid river culture. The river of Lishui is sprayed with snow and white waves in the joys of the four seasons, and it is not adjusted by the cold, which casts a strong character of the plateau people. This river is like a silver-white Hada, which gives the plateau people happiness and auspiciousness.
