According to historical records, the Han people have been oppressed and insulted since the Mongols unified the country. In the hearts of many Han people, they are secretly determined to take revenge. Therefore, after the demise of the Yuan Dynasty, many of his subjects gave full play to Zhu Yuanzhang's request, pursued the Mongols who fled back to the desert and quickly killed them to avenge them.

However, during the 80 years of the Yuan Dynasty, many Mongolians also married China people. If it is not handled properly, it will cause large-scale unrest. Moreover, the Mongolian ethnic policy was not handled properly, which led to Dayuan's complete loss of popular support. It is no good if they just kill blindly without solving ethnic problems. Solving ethnic problems can not only stabilize the country, win the hearts of the people, but also consolidate the dominant position.

In addition, Zhu Yuanzhang himself also attached great importance to the hierarchical order of feudal society. In his view, the Han people are orthodox in China, and the rule of the Mongols is a complete act of usurpation. Now that orthodoxy has been restored in the world, Han people are interested in moral etiquette. Treating northern barbarians should be based on the principle of benevolence, righteousness, courtesy and faith. If they stop invading, we don't need to take extinction measures. This is more in line with the needs of the times. Therefore, he said to the world: "The dream of Mobei is not the orthodox home of China, but everything in the world has the same origin. If you and other Mongolians can know the etiquette of the avenue, you can become a subject. "

This important move of Zhu Yuanzhang not only catered to the requirements of our traditional culture, but also stabilized the society, won the public opinion of all ethnic groups in Han and Mongolia, and was also in line with today's peaceful exchange.
