What was the large-scale relocation in Nanjing history?

For the first time, it was called "the Jin family moved south"-the Jin royal family moved south, built its capital and built health, and the northern aristocratic families and a large number of people moved abroad. At this time, the total number of northerners in Nandu Yangtze River Basin is about 700,000.

The second time was in the early Ming Dynasty, when Zhu Yuanzhang made Nanjing his capital, he moved a considerable number of former Jinling residents to the frontier of Yunnan, and immigrants from Zhejiang, Jiangxi, Huguang and other provinces, as well as fifteen states such as Suzhou, Songjiang and Changzhou, and Xuzhou, Chuzhou and Hezhou "occupied the capital". At that time, the total population of Nanjing was 473,200, and the foreign population accounted for nearly half.

The third population migration occurred in 1864, after Zeng Guofan led the Xiang army to attack Tianjing, the capital of the Taiping Heavenly Kingdom, and slaughtered the Taiping Army.

1937, after the Japanese captured Nanjing, the Nanjing Massacre was carried out, and 300,000 residents were massacred. The "Holocaust" drastically reduced the population, and many immigrants from other provinces poured in-this was the fourth large-scale immigration.
