1, Hu people are illiterate, and they can occupy some areas by force for a period of time, but to establish political power, they still need to test Chinese. (At that time, the Hu people called the Han nationality: China, Xia, China, China and Han)

2. During Luanhua period, the contradiction in the north was extremely complicated. Not only is the contradiction between China people and conference semifinals, but the contradiction between conference semifinals is sometimes more acute. Therefore, it is the best way for the Hu people to fight for some China people, especially the clans of the Chinese University. Therefore, there is a lot of cooperation between Hu people and China people. This cooperation mainly deals with other conference semifinals.

3. After the Hu people established political power, most of them refused to go in and gradually became corrupt. Therefore, the regimes they established were very short-lived.

4. During the chaos in China, due to the cruelty of the struggle, most of the conference semifinals were killed. Some ethnic groups are even basically extinct. For example, the Jie people (from Central Asia, who were slaves of the Huns at first, and later established the post-Zhao regime). Therefore, the customs of these conference semifinals have little influence on future generations.

5. The sinicization of Tuoba regime is a rare special case of sinicization in the history of China. It is estimated that the blood of the leader of the sinicization movement accounts for more than 90% of the Han nationality. Although many people tout this sinicization movement. But this movement is actually a failure. Because sinicization caused the fundamental interests of other ethnic groups (vested interests at that time) in the north. So when the leader died, those aliens rebelled, the Tuoba regime collapsed, and the cause of sinicization stopped, or even went backwards completely. At that time, foreigners despised China people and called them "educated China people". It means that China people are only worth a penny and can kill people at will.

6. In the more than 50 years before the Sui Dynasty, the north suffered cruel wars and killings, mainly among different ethnic groups. Therefore, very few ethnic groups survived. After the establishment of the Sui Dynasty, the political power of China people was naturally restored.
