Chizhishizhuhou Chanyu
The southern Xiongnu were a branch of the eastern Xiongnu that followed the rebellious pretender Huhanye and in 51-53 BC moved en masse within the Han borders under protection of Chinese. Since the times of Huhanye, the status of the southern Xiongnu was loyal allies of the Han Dynasty. The southern Xiongnu enjoyed material support of the old "heqin" treaty, and in return guarded the Chinese northern borders and participated in the Chinese external and internecine conflicts as long as the Chinese court respected their independence. However, when the Han imperial court attempted to appoint an ineligible for the crown Western Jükü-Prince Yufuluo from ineligible Right Wing as a Chanyu, instead of respecting the traditional election, the southern Xiongnu dissented and elected a lawful alternate Hyuibu Gudu-heu. Later they expelled Yufuluo, who had to seek safety in exile at the Han imperial court.
Donghu people
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.
Thus at this time there lived in the region west of Long the Mianzhu, the Hunrong, and the Diyuan tribes. North of Mts. Qi and Liang and the Jing and Qi rivers lived the Yiqu, Dali, Wuzhi, and Quyuan tribes. North of Jin were the Linhu (Forest Barbarians) and the Loufan, while north of Yan lived the Donghu (Eastern Barbarians) and Shanrong (Mountain Barbarians), each of them with their own chieftains. From time to time they would have gatherings of a hundred or so men, but no one tribe was capable of unifying the others under a single rule.
