Nanchang (Chinese: 南昌) is the capital of Jiangxi Province in southeastern China.As of 2010, a population of 5,042,565 live in the prefecture, in which 2,357,838 live in the area made up of all five urban districts.Located in the north-central part of the province, it is bounded on the west by the Jiuling Mountains, and on the east by Poyang Lake. Because of its strategic location connecting the prosperous East and South China, it has become a major railway hub in Southern China in recent decades.
As the Nanchang Uprising in 1927 is distinctively recognized by the ruling Communist Party as "firing the first gunshot against the evil Nationalists",the current regime has therefore named the city since 1949 "the City of Heroes", "the place where the People's Liberation Army was born", and the most widely known "place where the military banner of the People's Liberation Army was first raised".
Since 1949 Nanchang has been extensively industrialized. It is now a large-scale producer of cotton textiles and cotton yarn. Paper making is also a major industry, as is food processing (especially rice milling). Heavy industry began to gain prominence in the mid-1950s. A large thermal-power plant was installed and uses coal brought by rail from Fengcheng to the south. A machinery industry also grew up, at first mainly concentrating on the production of agricultural equipment and diesel engines. Nanchang then became a minor centre of the automotive industry in China, producing trucks and tractors and also accessories such as tires. An iron-smelting plant helping to supply local industry was installed in the later 1950s. There is also a large chemical industry, producing agricultural chemicals and insecticides as well as pharmaceuticals.
Nanchang is located 130 km (81 mi) south of the Yangtze River and is situated on the right bank of the Gan River just below its confluence with the Jin River and some 40 km (25 mi) southwest of its discharge into Poyang Lake.
