Thus, a story of Мао-tun advent to power total by Ssu-ma Ch'ien can not consider as a reliable account of events occurring in Mongolia at the border of 3–2 centuries ВС. One can only say conclusively that Мао-tun come to power by a way of usurpation and, thereafter, he defeated Tung-hu and forced them to pay tribute.
Here, new question arise before us and two of them appear to be most important. The first question is related to dating of all events mentioned in the legend. Alas! The time in the folklore works is not consistent with the real time. It obeys the subject and changes in accordance with the events (characters). But the second question is even more complicated: who was a founder of the 'black' legend of Shan-уй Mao-tun? In the main, this question is a key one an and a clue of the problem as a whole depends on the answer to it.
In accordance with the written and archaeological sources, the pastoral nomadism was a basic business of Hsiung-nu. As for the nomads of Mongolia and Transbaikalia in the later times, the Hsiung-nu bred a typical for Eurasia set of animals: sheep, cattle, horses and, more rarely, goats and camels. In addition, they had also in small proportion other species of domestic animals. The economic system of the Hsiung-nu empire was based not only on the pastoral nomadism. The Hsiung-nu developed the internal sedentarization and promoted the agrarian policy, and handicraft. They created the special settlements at the places fafourable for agriculture where they settled the immigrants from China and personers of war from the settled states. The best known settled sites of Hsiung-nu times are Ivolginsky fort and Dureny settlement in Buryatia.
A different nationality of the settled residents in the west Transbaikalia is confirmed by many arguments of the archaeological studies: (1) predominance in the materials of the Ivolginsky fort excavations of the bones of such ('non-nomadic") animals as dog and pig; (2) fishing business; (3) construction of warmed stove-benches in the houses — kangs; (4) typical Chinese agricultural tools; (5) Chinese shapes of vessels; (6) Chinese hieroglyphes on a pottery; (7) anthropologic determinations of skills from the Ivolginsky cemetery [Гохман 1960].
A problem of contacts between the nomads and farmers is among the permanently discussed problems. Almost the fundamental question is in an estimation of a role of nomads in these processes. Some believed that the nomads were first of all robbers since earliest times and conquerors who brought death and destruction to people. While other considered that nomads were creators of the original mobile culture. The supporters of the latter standpoint see, as a rule, the relations between nomads and settled people within the framework of different conceptions of 'symbiosis'. It would be improper to regard the relation between nomadic and settled people unilaterally, only as enmity since earliest times or, on the country, symbiosis. In a reality, a situation was more complicated. Over the course of the Hsiung-nu empire existence, the relations between nomads and Han have not remained unchanged but have subjected to a particular evolution. One can identify four stages of the Hsiung-nu — Han relations.
At the first stage (200–133 ВС) for extortion of more higher profits, the Hsiung-nu have attempted to alternate the war and raids with the periods of a peaceful co-habitation with China [see Barfield 1981; 1992]. The first raids have been carried out to obtain a booty for all member of the imperial confederation of nomads regardless of their status. The Shan-уй should enlist the support of a majority of tribes being members of the confederation. After the devastating raid, the Shan-уй has, as rule, send the ambassadors to China with an offer to conclude a new agreement of 'A peace and relationship' pr, alternatively, the nomads have continued their raids until the Chinese have applied with an offer to conclude a new agreement. After concluding the agreement and obtaining gifts, the raids have ceased for any time. However, after a time when a booty plundered by simple nomads has finished or become worthless, the cattle-breeders have against begun to demand from chiefs and Shan-yii a satisfaction if their interests. By virtue of the fact the border, the Shan-yu has been forced to 'release a steam' and to issue an order to renew to raids.
