Jiangnan region: Hubei, Hunan, Jiangxi, Zhejiang, Anhui, Jiangsu, Shanghai and northern Fujian (extending eastward from Nanling).
Description of National Secondary Meteorological Geographical Division:
Jiangnan area: The north-south basic Zhejiang-Jiangxi and Hunan-Guizhou railway lines are divided into south and north, and the east and west are basically divided into east, middle and west by the north-south extension line between northeast Jiangxi Province and Zhejiang and the boundary line between Jiangxi and Hunan.
In different historical periods, the literary image of Jiangnan is different. Jiangnan first appeared in the pre-Qin and Han Dynasties. The Eastern Zhou Dynasty was the middle and lower reaches of the Yangtze River where the vassal states of wuyue were located, that is, some areas south of the middle and lower reaches of the Yangtze River, such as Shanghai, northern Zhejiang, southern Jiangsu, southeastern Anhui and northeastern Jiangxi (from the CCTV documentary "Where is Jiangnan").
Since ancient times, there have been administrative divisions such as Huiji County, Wu Jun County, Jiangnan Road and Liangzhu Road in the Han nationality areas in the south of the Yangtze River.
Extended data:
Compared with the north, the most obvious features of the terrain in the south of the Yangtze River are hills, plains and waters. Jiangnan is located in the hilly plain of the middle and lower reaches of the Yangtze River, with high terrain in the south and low terrain in the north. Its northern part is flat, mainly plains and hills, while some mountains are distributed in the south. In addition to abundant precipitation, there are two major water systems in the south of the Yangtze River and Qiantang River, which are connected by canals.
There are many rivers and lakes in the south of the Yangtze River. There are three famous freshwater lakes in China, namely Poyang Lake in Jiangxi, Dongting Lake in Hunan and Taihu Lake in Jiangsu and Zhejiang.
In the long-term development process, a large number of water conservancy projects have been built to connect them, such as Wu Zixu Kaixuxi, Fucha Ditch and Jiangnan Canal. Therefore, it has always enjoyed the reputation of "Water Town Zeguo". The physical geography of the south of the Yangtze River formed under such climate and topography is significantly different from that of the north.
Jiangnan is not only famous for its land of plenty and beautiful scenery, but also one of its traditions, which also casts the cultural character of some Jiangnan people. Jiangnan culture is the representative of long-lasting love, and the well-known stories such as talented people and beautiful women are another praise for the cultural heritage. The classical Jiangnan architectural style with white walls and blue tiles and small bridges flowing water also has a quiet and beautiful charm. The dishes are exquisite, salty and sweet, and they are also representatives of some Jiangnan areas.
Jiangnan is famous for its prosperous culture and education. Nanjing Qinhuai River Confucius Temple is a temple in memory of Confucius. Jiangnan Palace Garden in the Confucius Temple complex is an examination room for ancient students and a symbol of Jiangnan imperial examination culture.
