About the great migration of ethnic groups during the Anshi Rebellion in the Tang Dynasty

The Anshi Rebellion was a turning point in population migration during this period, which was mainly manifested in the large number of Han people from the Central Plains migrating southward again. History books say that "the people in the world were well-dressed and common people, and they avoided Soochow. Yongjia moved southward, but it did not flourish here." "During this period, the Han people who migrated south mainly moved from the North China Plain and the Guanzhong area to Huainan, Jiangnan, Hubei, Hunan, Sichuan, Fujian and other places, and the farthest moved into the Lingnan area. This time "the northerners' southward migration, which lasted for a century and a half, spread throughout the southern regions, was very large, and its distribution area was much wider than the southward migration after Yongjia." This large-scale migration of the Han population directly led to the population ratio between the north and the south. From 6:4 to 4:6, the Yangtze River Basin has since replaced the Yellow River Basin as the center of China's population distribution.

During the Sui and Tang Dynasties, the Lingnan and Southwest Yi areas had always been settlement areas of the Man, Liao, and Li ethnic groups. During this period, the Han population entered the minority inhabited areas of Sichuan, Guizhou, Yunnan, and Guangdong and Guangxi. There are more of them than in the Wei and Jin Dynasties, and they are distributed over a wider area. For example, the heyday of Nanzhao was the climax period after the Han and Jin Dynasties when Yunnan and its surrounding areas absorbed a large number of Han people from the mainland. Hundreds of thousands of Han people from the mainland settled in Erhai, Dianchi and other places, which had a great impact on the changes in the ethnic composition of Yunnan. Big impact. The large-scale immigration of Han people has further broken up the local ethnic minority settlement pattern, and the situation of mixed ethnic groups in southern my country has become increasingly obvious.
