Mainstream survey

In ancient times, it was called Liaoshui, which came from two sources. Donglao River originates from Jingyunao, Xilao River originates from Qinling Mountains, flows northward after the two rivers meet, and finally flows into Weihe River through Xianyang. The total length of the old river is 82 kilometers, with a total drainage area of 663 square kilometers.
