The Liao people are the Khitan people. During the heyday of the Liao Dynasty, its territory extended to the Sea of ??Japan in the east, the Altai Mountains in the west, the Ergun River and the Greater Khingan Range in the north, and the Baigou River in southern Hebei Province in the south.
The Jin people are the Jurchen people. On the land of Northeast Asia live the Jurchen tribe, a Tungus ethnic group inherited from the Blackwater Mohe. That is now the three eastern provinces.
The Xiongnu were located in the Hetao and Daqingshan areas of Inner Mongolia today, and later spread to all parts of the world with the migration of the Xiongnu. When the Xiongnu people emerged, the Guifang, Hunchu, Yinxi, Rong, Di and other ethnic groups appeared successively in the north and south of the desert on the Mongolian Plateau. The Xiongnu people emerged from the struggle and integration of these ethnic groups.
Extended information:
The Xiongnu were a nomadic people in northern China in ancient China. They arose in the foothills of Yinshan Mountain in present-day Inner Mongolia. According to records in "Historical Records: Biography of the Xiongnu", the Xiongnu were the descendants of their ancestors, the Xia Hou family, and were named Chunwei. In the Tang and Yu periods, there were Shanrong, yangxu, and Xunzhu, who lived in the northern barbarians and moved with livestock. The Xiongnu in ancient Chinese books were a powerful nomadic people who dominated the north of the Central Plains at the end of the Qin Dynasty and the beginning of the Han Dynasty.
In 215 BC, the Xiongnu were expelled from Hetao and the Hexi Corridor area by Mengtian. The Xiongnu became powerful in the early Western Han Dynasty and repeatedly invaded the borders, posing a strong threat to the Western Han Dynasty and controlling the Western Regions. They were later defeated by Emperor Wu of the Han Dynasty and retreated to Mobei and split into five tribes. In 119 BC, General Huo Qubing, surrounded by the Han army and the surrendered Huns, "sealed the wolf to live in Xu Mountain, meditated in Guyan, and climbed to the Hanhai (today's Lake Baikal)".
In 53 BC, the leader of the Southern Huns, Hu Hanxie Shanyu, led his people to surrender to the Western Han Dynasty. In the first year of Emperor Liu Shijingning of the Han Yuan Dynasty (33 BC), Huhanxie Chanyu came to the Han Dynasty for the third time and asked himself to be his son-in-law. Wang Zhaojun married him. After that, the Han Dynasty and the Xiongnu maintained peace for more than 60 years. During the Eastern Han Dynasty, the Xiongnu split again into the Southern and Northern Xiongnu. In AD 48, the Southern Huns killed their corpses and drove the Shanyu to surrender to Emperor Guangwu Liu Xiu, and they were placed in the Hetao area.
The Northern Xiongnu’s unsteady rebellion made the Eastern Han Dynasty determined to destroy the Northern Xiongnu. In AD 89, the first year of Emperor Liu Zhaoyong of the Han Dynasty, General Dou Xian defeated the Northern Huns. Ban Gu carved a stone at the southern foot of Yanran Mountain (now Hangai Mountain in Mongolia) and inscribed the "Feng Yanran Mountain Inscription" to record his achievements. The Southern Xiongnu established the former Zhao regime during the Five Hus and Sixteen Kingdoms period. The Tiefu people, the mixed descendants of the Xiongnu and Xianbei, established the Huxia.
