The Oroqen are one of the fifty-five officially recognized ethnic minorities of the People's Republic of China. They are found in Heilongjiang Province (Huma, Xunke, Aihui, and Jiayin counties) and the Inner Mongolian Autonomous Region (mainly in Hulun Buir League). Their language,which belongs to the Tungus Branch of the Manchu-Tungus Family of Altaic languages, has no script. "Oroqen" means "mountain people" or "reindeer herders"; both are accurate descriptions of their environment and traditional way of life. Roving in the Greater and Lesser Hinggan mountains during long cold winters and greatly abbreviated summers, they are known as excellent hunters. According to the 1990 census, the Oroqen population stands at 6,965.
