Tang Tianbao period: An Shi Rebellion, the economic center of gravity moved south again, and the south replaced the economic status of the north. Because many famous ministers in the Tang Dynasty, such as Xu Yuan and Zhang Xun, adhered to Suiyang, the south was not destroyed by the war like the north, and the south was preserved. Because a large number of northerners fled to the south, the south brought labor, which made Jiangnan's economy increasingly developed, and eventually the economic scale exceeded that of the Central Plains.

During the Jingkang period of the Northern Song Dynasty, the Jin Dynasty moved more than 100,000 people, including the imperial family Bianjing (now Kaifeng City), empresses, officials and civilians from the capital to Daxing House in Zhongdu (now Beijing).
