Did the ancient nomadic people look down on the Han people? Why can't peace exist? Maybe we can merge and rule the grassland together. Why don't Mongols and Han Chinese?

There are not only individual differences but also group differences in people's intelligence and thinking tendency.

Han people have long adapted to agricultural life, while Mongolians have long adapted to nomadic life.

Although the Han people are divided to some extent, they still need a complicated social division of labor and a systematic regime to manage their lives.

Mongolian society has little division of labor and strong division, and there is no strong unity in other periods except Genghis Khan.

If the dispute between Han and Mongolian is eliminated, it will be very difficult to integrate. Mongolians are unwilling to farm, while Han people are unwilling to graze. Just like blacks, the crime rate of blacks in the United States and Africa is very high, because the jungle and grassland life in Africa is loose and free, and they can never adapt to modern national life. If Mongolians and Han Chinese divide and rule and have equal status, then Mongolians can't resist the trade plunder of Han Chinese at all and will become poorer and poorer. In the past, Liao and Jin lost a lot in the trade of Song Dynasty. Song dynasty used some money to buy peace, but after peace, Song dynasty plundered more wealth from Liao and Jin through trade.

At that time, the Han people and the Mongols despised each other, and no one looked down on each other. Although the Mongols completely wiped out the Han Dynasty for the first time, they were killed by a Khan in Sichuan (Yang Guo killed the Mongols in the battle of Xiangyang City in The Legend of the Condor Heroes, actually transplanted from the battle of Fishing City in Sichuan, and the Mongols were killed by flying arrows and stones in Song Jun), so it can be said that the war to fight the Southern Song Dynasty is the hardest and most difficult. Although the Han people were ruled by the Yuan Dynasty for a hundred years, Ming Taizu and Ming Chengzu's repeated northern expeditions later beat the Mongols out of the water, which could no longer pose a fatal threat to the Central Plains.
