Jiangxi (Chinese: 江西; pinyin: Jiāngxī; Wade–Giles: Chiang-hsi; Postal map spelling: Kiangsi, Gan: Kongsi) is a province in the People's Republic of China, located in the southeast of the country. Spanning from the banks of the Yangtze River in the north into hillier areas in the south and east, it shares a border with Anhui to the north, Zhejiang to the northeast, Fujian to the east, Guangdong to the south, Hunan to the west, and Hubei to the northwest. The provincial capital is Nanchang
The name "Jiangxi" derives from the circuit administrated under the Tang Dynasty in 733, Jiangnanxidao (江南西道, Circuit of Western Jiangnan; Gan: Kongnomsitau). The short name for Jiangxi is 赣 (pinyin: Gàn; Gan: Gōm), for the Gan River which runs across from the south to the north and flows into the Yangtze River. Jiangxi is also alternately called "Ganpotaiti" (赣鄱太地) which literally means the "Great Land of Gan and Po"
