Many immigrants lived in the Xiongnu pasturelands, but at first they did not mix with the Xiongnu. To be a Xiongnu, one had to be a member of a clan, born of Xiongnu parents. The newcomers were well off, but were outsiders, and could marry only among themselves, not the Xiongnu. Only later did they intermix, increase in numbers, even created a state that existed from 318 to 350 AD.
History of Siberia
As early as the first millennium BCE, trade was underway over the Silk Road. Silk goods were imported and traded in Siberia.
The establishment of the Xiongnu empire in the 3rd century BCE started a series of population movements. Many people were probably driven to the northern borders of the great Central Siberian Plateau. Turkic people such as the Yenisei Kirghiz had already been present in the Sayan region. Various Turkic tribes such as the Khaka and Uyghur migrated northwestwards from their former seats and subdued the Ugric people.
