What are the large-scale population movements in the history of China?

Our population originally lived in the middle and lower reaches of the Yellow River. Since Qin and Han Dynasties, due to natural environment and social reasons, people's center of gravity and economic center of gravity have been moving south. Large-scale centralized population migration includes:

(1) "Yongjia mourning" period: It happened in Yongjia period of the Western Jin Dynasty, and the decadent rulers brutally exploited and oppressed people of all ethnic groups, thus making people in the Yellow River basin displaced and forced to move to Jianghuai basin on a large scale (mainly into Jiangsu, Anhui, Hubei, Sichuan and other places). The population moving south is about 900,000, which has changed the pattern of large population in the north and small population in the south since Qin and Han Dynasties. The population in the south has increased rapidly, which has promoted the rapid economic development in the south. This is a landmark event that the population distribution center of China has shifted to the Yangtze River basin.

(2) The "An Shi Rebellion" period: It happened in the Tang Dynasty, and about 1 10,000 people moved south, which fundamentally changed the pattern of population distribution in China concentrated in the Yellow River basin, and the proportion of population distribution between the north and the south of China reached a balance for the first time.

(3) The "Jingkang Rebellion" period: It happened in the Northern Song Dynasty. 1 125, Jin destroyed Liao and began to attack the northern song dynasty in the south. The Yellow River basin has become the main battlefield. Every major war caused a large number of residents in the Yellow River basin to migrate to the Yangtze River basin, mainly to Zhejiang, Jiangsu, Hubei and Sichuan, which was the largest stage of population migration in the late Northern Song Dynasty.

(4) During the period of "Jin Yan and Yan Liang invaded south":11Jin tore up the peace treaty with the Song Dynasty, and invaded south on a large scale, and the Huaihe River basin became the main battlefield, forcing the residents of the Huaihe River basin to move south to the Yangtze River basin, mainly to Zhejiang, Jiangsu, Hunan, Jiangxi and other places.

(5) Period of "Mongolian soldiers invading south": After Kublai Khan ascended the throne of Khan, he sent a large number of Mongolian soldiers to invade south on 1273, and launched a war to destroy the Southern Song Dynasty. The main battlefield is in the middle and lower reaches of the Yangtze River, and a large number of local residents have moved to the Pearl River basin to escape the war, mainly in Guangdong, Guangxi and Fujian.

After the above-mentioned population migration, the population in the south greatly surpassed that in the north, and the south of China became the most densely populated area in China. At the same time, the social economy in the south of the Yangtze River basin has developed greatly, which can be said to be the transfer of China's population center and cultural center from the Yellow River basin to the Yangtze River basin.

(6) the period of "going west and going east"

/kloc-In old China in the late 20th century, after the invasion of Russian and Japanese imperialism, the two countries competed to expand their power in the northeast, build railways and plunder resources, which required a lot of labor, thus forcing farmers in North China to go bankrupt and move to the northeast, especially in Shandong and Hebei provinces. In addition, there are also many immigrants from Henan, Shaanxi and other provinces in Gansu, Qinghai and Xinjiang in the northwest.

(7) The period of "Southeast Coast Heading for South China Sea"

After European and American capitalism invaded Southeast Asia, in order to plunder the resources of Southeast Asia, they recruited farmers who went bankrupt in the middle of the Zhou Dynasty as labor resources to develop colonies and sold China laborers, which led to a sharp increase in the population of Southeast Asia.
