Genghis Khan can establish the Mongolian empire, and the rules are very important. Is reusing Han Chinese one of the success factors?

Reusing Han people is indeed an important reason why Genghis Khan unified the world. Genghis Khan unified the Mongolian plateau by means of war. At this time, there were strong enemies of the Jin Dynasty and the Southern Song Dynasty. Genghis Khan used the cruelty of foreign wars to encourage tribes to be consistent with the outside world. In foreign wars, Genghis Khan never excluded the Han people, but appointed them as military advisers. Although Genghis Khan did not have the ability to assimilate the Han people, he treated them like one of his own. So some talented Han Chinese took refuge in Genghis Khan, and with the help of Han Chinese, they got rid of the control of the rulers.

Under the oppression of the Jin people, the Mongols are United. However, in the early days, both sides suffered losses. On the other hand, Genghis Khan's tribal losses are a bit serious. Genghis Khan thought there were some problems with his strategy, so he consulted the Han people many times and later worshipped them as military advisers. From then on, I trusted the Han people every time I fought. As a result, Tongguan and other important places were quickly breached, and many problems appeared in the rulers. The peasant army constantly revolted, and the rulers were wiped out by the Mongols under the internal and external troubles.

After the Mongols unified the Central Plains, they began to conquer the Western Regions. In order to solve this problem, Genghis Khan boldly hired Han Chinese to escort food and grass, and some important positions were also held by Han Chinese. After solving the problem of grain and grass, Genghis Khan began his three expeditions, which occupied most of the territory of the western regions. Now Eurasia is beginning to fear the Mongolian Empire.

After Genghis Khan's death, his descendants began to distrust the Han people and refused to be sinicized internally, which split the ruling class and worried the court. After several generations, the court became increasingly corrupt, and the court did not appoint loyal ministers. The sinicization system failed, so that the emperor lost the support of Mongolian nobles, and soon the Yuan Dynasty perished.
