"Mighty good dugouts, these," thought Gray. "The Wusun have certainly dug themselves in on their ancestral hearths. Wonder how they manage for food?" He asked Garluk this question. The Wusun responded that he and certain of his companions—the tumani—were allowed to go out on the plain through the lines of lepers and hunt the wild camels and gazelles of the plain. Also, the Buddhists maintained several shepherd settlements near the River Tarim, a journey of three or four days to the west.

Some citrons, melons and date trees grew by the canals of Sungan. At times a caravan would come to Sungan from China bringing other food.
