"Heilong Jiang" is a Chinese name that refers to a river located in Northeast China. In English, this river is commonly known as the "Black Dragon River." The name originates from the dark, murky color of the river's water, which resembles the scales of a black dragon. The Heilong Jiang also goes by several other names such as the Amur River, which is a transliteration of its Russian name, "Amur." In Chinese, it is also known as the "Heilongjiang River" and "Wusuli River."
