Reindeer Ewenke people, living in Aoluguya Ewenke Ethnic Township, Genhe city, Inner Mongolia Autonomous Region, is a special ethnic minority group directly transformed into the socialist society from the end of the primitive society. Historically known as "the Reindeer Tribe," it is the "last hunting tribe in China," and also the only ethnic group in China that raises reindeer and preserves the "reindeer culture" so far.
