The (ca. 109–91 BCE) "Shiji" section on Xiongnu history first records the Donghu during the era of Duke Wen of Jin (r. 697–628 BCE) and Duke Mu of Qin (r. ca. 659–621 BCE).At this time Qin and Jin were the most powerful states in China. Duke Wen of Jin expelled the Di barbarians and drove them into the region west of the Yellow River between the Yun and Luo rivers; there they were known as the Red Di and the White Di. Shortly afterwards, Duke Mu of Qin, having obtained the services of You Yu, succeeded in getting the eight barbarian tribes of the west to submit to his authority.<br>
