The reason why the population of Central Plains moved south.

During the Wei, Jin, Southern and Northern Dynasties, the Central Plains fell into a long-term civil war again, and the north fell into the hands of foreigners for the first time, so that people from the Central Plains fled to Lingnan one after another, and the population of Han nationality in Lingnan increased greatly. This is the first peak of the migration of Central Plains population to the south in the history of China. At that time, Chinese introduced from the Central Plains was mixed with old Cantonese, which narrowed the difference between old Cantonese and Central Plains Chinese.

1. "Yongjia mourning" period

During the Yongjia period of the Western Jin Dynasty, the decadent rulers brutally exploited and oppressed people of all ethnic groups, which led to the displacement of people in the Yellow River basin and forced them to move to the 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. "An Shi Rebellion" Period

In the Tang Dynasty, about 6,543,800 people moved south, which fundamentally changed the population distribution pattern in China with the Yellow River basin as the center of gravity, and the population distribution ratio between the north and the south of China reached a balance for the first time.

3. "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 has 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. This is the biggest stage of population migration in the late Northern Song Dynasty.

4. Jin Yan Hong Liang period

1 16 1 Jin tore up the contract with the Song Dynasty and invaded the south on a large scale. 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 and Jiangxi.

5. The period of "Mongolian soldiers invading south"

After Kublai Khan and others arrived at Khan's position, 1273, a large number of Mongolian soldiers invaded the south and launched a war to destroy the Southern Song Dynasty. The main battlefield is in the middle and lower reaches of the Yangtze River. In order to escape the war, a large number of local residents moved to the Pearl River Basin, mainly in Guangdong, Guangxi and Fujian.

6. The period of "going west and going east"

/kloc-After imperialism invaded old China in the late 9th century, China, Russia and Japan competed to expand their power in the northeast, build railways and plunder resources, which required a lot of labor, forcing North China to go bankrupt, and farmers moved to the northeast one after another, especially in Shandong and Hebei provinces. Between 1923- 1930, there were 3 million farmers moving to the northeast, with 65,438+. In addition, there are many farmers in Gansu, Qinghai and Xinjiang in the northwest, such as Henan and Shaanxi provinces.

7. The period of "southeast coast going south"

After the European and American capitalism invaded Southeast Asia, in order to plunder the resources of Southeast Asia, they recruited bankrupt farmers from China as the labor resources for developing colonies and sold labor from China, which led to a sharp increase in the population of Southeast Asia.

The plain in the middle and lower reaches of the Yellow River is the birthplace of the Chinese nation. Since the Qin and Han Dynasties, the population of China has spread from the middle and lower reaches of the Yellow River to the surrounding areas, with emphasis on the Yangtze River basin and the Pearl River basin in the south. The population migration caused by "An Shi Rebellion" fundamentally changed the geographical distribution pattern of China's population, making the population in the south surpass the population in the north for the first time, and the population distribution center in China shifted from the Yellow River basin to the Yangtze River basin for the first time.

The most direct causes of population migration in the history of China are migration, war and natural disasters. For example, in the history of our country, every time there is a war or famine, it will cause a large-scale population migration.
