evidence: Heilongjiang (Simplified Chinese: 黑龙江省; Traditional Chinese: 黑龍江省; pinyin: Hēilóngjiāng; Postal map spelling: Heilungkiang; Manchu: Sahaliyan ula) is a province of the People's Republic of China located in the northeastern part of the country. "Heilongjiang" literally means Black Dragon River, which is the Chinese name for the Amur River. The one-character abbreviation is 黑 (pinyin: Hēi), and the Manchu name of the region is Sahaliyan ula (literally meaning "Black river"), from which the name of Sakhalin island is derived. Heilongjiang borders Jilin to the south and Inner Mongolia to the west, and it also borders Russia to the north, with the Amur River marking the territorial border between the two countries. Heilongjiang contains both China's northernmost point (in Mohe County along the Amur) and easternmost point (at the junction of the Amur and Ussuri Rivers). Heilongjiang's culture is part of a culture of Northeast China that is relatively homogeneous across all northeastern China.
