Who ruled the Mongolian Plateau before Xiongnu?

1. Before the Xiongnu, the ancestors of all ethnic groups in the Xiongnu Alliance ruled the Mongolian Plateau, such as Guifang, Gourong, Shanrong, Chidi, Bai Di and Yi. The names of each dynasty, generation and tribe are different, but they are all the same kind of people, that is to say, the Altai yellow race and the white race are hybrids;

Qin Shihuang crusaded against Xiongnu, mainly to recapture Hetao. During the Warring States period, the Huns took advantage of the war in the Central Plains countries and gradually occupied the Hetao area. Qin Shihuang sent Meng Tian to raise hundreds of thousands of troops, chase the Huns Tou Man Khan in the north, recapture Hetao and build the Great Wall of Wan Li. Another reason why Qin Shihuang fought against Xiongnu was that an alchemist named Lu Sheng told his fortune and said, "If Qin dies, Hu dies.".

3. The Huns did not reach the northernmost Arctic Ocean in the territory of Mongolian Plateau, but just north of Lake Belga; Other ancient nomads did not have the concept of modern territory. At that time, some tribes of the Xiongnu League were living near the Arctic Ocean, and the center of gravity of Xiongnu ontology was in the Monan grassland. At that time, Sahayakut, Chuvash, Chukchi and other ethnic groups near the Arctic Ocean were themselves descendants of ancient Asians and members of the Xiongnu League.
