In the Eastern Zhou Dynasty, it was the middle and lower reaches of the Yangtze River where the vassal states of Wu and Yue were located, i.e., present-day Shanghai, northern Zhejiang, southern Jiangsu, southeastern Anhui, northeastern Jiangxi, and other areas south of the middle and lower reaches of the Yangtze River (from the CCTV documentary "Where is Jiangnan").

Since ancient times, there have been administrative divisions in the Han region of Jiangnan, such as Huiji County, Wu County, Jiangnan Road, and Liangzhe Road.
