There are more than 1,900 rivers in Heilongjiang, including the Songhua River, Heilong River and Wusuli River, creating a convenient system of waterway transportation. Harbin harbor is one of eight inland ports in China and the largest of its type in Northeast China. Available from mid-April until the beginning of November, passenger ships sail from Harbin up the Songhua River to Qiqihar, or downstream to Jiamusi, Tongjiang, and Khabarovsk in Russia.
