What are the effects of population migration in the late Western Jin Dynasty?

It has made contributions to the great development, ethnic integration and economic development of Jiangnan area.

A large number of Han people moved south, which not only enriched the labor force in the south, but also brought advanced productive forces, promoted the development of productive forces in the south, and laid the foundation for the economic center of China to move south in the future.

As the Han people moved south, the northern minorities moved south to the Central Plains, which brought great damage to the economy of the Central Plains and brought disaster to the Han people who stayed in the Central Plains. At that time, the Han people were called "two-legged sheep", which was the history of blood and tears of the Han people.

However, the migration of ethnic minorities to the south has objectively accelerated the integration between ethnic groups.

It laid the foundation for the reunification of the Sui and Tang Dynasties.
