In the ancient history of China, how many times did the famous population move south?

There were three large-scale trips to the south.

1, in the late Western Jin Dynasty, the Indian Eight Kings Rebellion, the ethnic minorities around the Central Plains took the opportunity to rise and set up political power in succession, which caused the chaos in China, and a large number of people and clans began to cross south. In 3 17, Si Marui proclaimed himself emperor in Jiankang and rebuilt Wu, which was known as the Eastern Jin Dynasty in history.

2. After seven years of Anshi Rebellion in the Tang Dynasty, the ruling foundation of Li Tang regime was seriously shaken. Subsequently, the northern Hu people invaded the Central Plains, and the Tang Dynasty entered an era of war and separatist regime, followed by a more chaotic period of the Five Dynasties and Ten Kingdoms. During this period, from "Ming Di prospered Shu during the Anshi Rebellion" to "Nuodi prospered Shu" during the Huang Chao Uprising, Sichuan became the last turning point of the Tang Dynasty and another major direction of population migration. After Zhu Wen usurped the Tang Dynasty, Li's descendants from the other side occupied the south (i.e. Southern Tang Dynasty), and a large number of Central Plains people migrated to the south.

3. After the Jingkang Rebellion, Zhao Gou fled south and established the Southern Song Dynasty in Lin 'an. A large number of Han people in the Central Plains migrated to the south. Later, the Mongols occupied the Central Plains, which was seriously damaged. Jiangnan in the south, as the ruling center of the Southern Song Dynasty, replaced the Central Plains as a new economic center. This southern crossing took place in 1 127 (namely, the first year of Zhao Jianyan and the second year of Jingkang), so it is also called the southern crossing of Jian Yan.

After that, although the Qing Dynasty once again entered the Central Plains, the whole Central Plains region at that time had been plagued by natural disasters (small glacier period) and man-made disasters (bandits), and the people had nowhere to escape. In addition, the Qing dynasty adopted a series of political measures, which quickly stabilized the social production in the ruling areas, so there was no large-scale southward crossing.
