Starting point introduction: The starting point of the Wusuli River is Hutou Town in Hulin City. In the Wusuli River Square, tourists can see a stone tablet marking the starting point, which is a must-take photo spot for tourists. The Ussuri River was originally an inland river in China. It became a boundary river only after Tsarist Russia forced the Manchu Qing government to sign the "Beijing Treaty" in 1860. The Muling River flows into the Songaca River and joins the Iman River originating in Russia in Hutou Town, Hulin City, and begins to form the Ussuri River.
