These factors have promoted the development of Jiangnan area.

Analysis:

Jiangnan area was regarded as a barbarian land in Qin and Han dynasties, with backward economy and sparse population, far from the economic, cultural and political center of the north at that time, and its development was slow. However, after the Qin and Han Dynasties, China has been in a state of division, and wars have been raging in the north. Coupled with the nomadic people on the northern grassland harassing the Central Plains, the northern center was in a turbulent situation at that time, and the northern people moved southward on a large scale. Now people from Shandong, northern Jiangsu, Jianghuai and other places immigrate to southern Jiangsu, southern Anhui and Zhejiang. People from Henan and Hebei immigrated to Hubei and Hunan. Shaanxi people go to Bashu. This great migration brought China's most advanced science and technology, agriculture and handicraft technology, as well as a lot of labor and capital to the south, which laid a solid foundation for the rapid development of Jiangnan in the future, and also laid the groundwork for the economic, cultural and political center of China to move southward in the future.
