In the Greater Xing’ an Mountain of northern China, there is a group of people who share their life with the reindeers. These Ewenkis people came from Siberia over three hundred years ago. They have been living in the dense primeval forest and surviving on hunting and raising reindeers in their own traditional way. In 2003, the Reindeer Ewenkis came out of the forest and moved down to the new settlement built by the government. Now with hunting also banned, the Reindeer Ewenkis find themselves in a dilemma. Time is passing… the sounds of deer bells are fading away… Maria Suo, the last chief of the tribe, watches the changing of time helplessly. But does the forest the Ewenkis used to know still belong to them?
