Is it because the Han people can't protect their homeland that Mongolia went south to the Qing army to enter the customs?

It is wrong to say that you are incompetent. From a realistic point of view, Chinese immigrants from all over the world still live very well. If there is a war, nomads are natural guerrillas. If you can't kill him, you have to be careful. If you are weak, you can't play. Looking at the thoughts of the Han people, in short, the vast majority of Han people are egoists. What should I do if Mongolian troops occupy our villages and counties? Obviously not! In the case of the inability of the Han central Committee to resist, joining the winner's camp is obviously the best solution. Besides, people dare not engage in genocide and the land carrying capacity is limited. What are you trying to do? When the Japanese invaded the border city of Haicheng, the militia and the Japanese fought fiercely for three hours, but no one bled. What's more, all ethnic origins are played by westerners, and the vast majority of Han people only have regional discrimination without racial discrimination. First, I don't hate foreigners. Second, I'm not here to kill me. Third, no matter who rules, you have to pay taxes anyway.
