How did Migration in the Western Jin Dynasty put forward the idea of ethnic issues?

Jiang Tong, a native of the Western Jin Dynasty, was a county magistrate at first, and later rose to be a prince to wash horses. During the Jin, Yuan and Kang Dynasties, the Xianbei leader Bald Tree Function and the border leader Qi Wannian launched two large-scale rebellions. In this context, Jiang Tong wrote On Relocation, but his opinions were not adopted by the court. 10 years later, the Wuhu ethnic group took advantage of the rebellion of the Eight Kings in the Western Jin Dynasty to launch an extinct massacre of the Han nationality in the Yellow River Basin, which was called the "Five Rebellions" or the "Yongjia Rebellion" in history.

The highlight of Jiang Tong's article lies in seeing the great differences in values and lifestyles between the Han nationality and Wuhu nationality living in the Central Plains, and realizing that this difference is difficult to eliminate in a short time, and it is easy to cause civil strife in the hinterland of the Central Plains. Therefore, the author advocates taking advantage of the opportunity of the initial rebellion of the Hu people and the fact that the imperial army has not yet withdrawn, moving the Wuhu people out of the Great Wall, avoiding future troubles forever, strengthening national defense construction and improving the preparation for foreign struggle. However, the author failed to realize that the huge and dangerous project of moving the capital to Wuhu was by no means unbearable for the rulers of the Western Jin Dynasty who were addicted to wine and wine. In addition, ethnic migration itself is a sensitive work, and improper operation may also harm future generations: for example, Soviet leader Stalin moved several ethnic minorities in the Caucasus to Central Asia in World War II to prevent them from taking refuge in Germany, but the ethnic contradictions caused by it have made the Caucasus turbulent to this day. It is doubtful whether the migration of Hu people is effective: the Ming Dynasty strictly prevented northern nomads from entering the territory, and also implemented an assimilation policy for Mongolians and Semu people left over from the Yuan Dynasty, stipulating that their marriage must be aimed at Han people, but they still died in the Qing Dynasty, which was established by nomadic people. In fact, the stability of a country depends on political civilization and national defense consolidation, and whether foreigners live within national boundaries is a secondary issue.

However, this article by Jiang Tong implies a fact: a nation that does not cherish its own values and lifestyle will not be forgiven by history. The rulers of the Western Jin Dynasty did not assimilate the descendants of nomadic people living in the hinterland of the Central Plains and allowed them to keep their original customs and habits, which can be said to be an important reason for the "Yongjia Rebellion". Looking at western Europe after World War II, Muslim immigrants who were blindly introduced by local people as cheap labor for post-war reconstruction have been deeply rooted in the land of various countries, coupled with high birth rate and devout religious beliefs, which have the momentum of overwhelming the local major ethnic groups in culture. Today, after the end of the Cold War, the clash of civilizations has increasingly become the theme of international affairs. How to defend the cultural security of China is worth pondering by every patriotic China people.
