jiangnan
Jiangnan (name) means the name of a loosely defined area of China that always takes in the lands lying south of the Yangtze's lower reaches, in Shanghai together with southern Jiangsu and northern Zhejiang, and that sometimes also includes its cultural sphere lying north of the river, sometimes reaching as far south as Guangdong.
Etymology
This word comes from Hanyu Pinyin Jiāngnán, reflecting the Mandarin pronunciation of Chinese 江南 (Jiāngnán, “[Place] South of the [Yangtze] River”), which in turn goes back to the Classical Chinese use of 江 (jiāng) as a proper name for the Yangtze.
