History
Nanchong was in the territory of the state of Ba before it was conquered by the Qin in 314 BC. The Qin set up an administrative center at Langzhong City. Anhan City was established in Shunqinq district at the beginning of the Han Dynasty.

In 202 BC, Emperor Gaozu of Han instituted the Anhan County in this place. Anhan literally means "to establish or stabilize Han". In 8 AD, the name was changed to Anxin when Wang Mang seized the throne of the Han Dynasty, but it reverted to Anhan in 25 AD. It was again changed to Guozhou  in 621 AD (Tang dynasty), and then to Nanchong in 742 AD. The nickname of Nanchong is Guocheng, derived from Guozhou.

Nanchong is in the northeast of Sichuan Province. To the east of Nanchong is Dazhou, to the west are Mianyang and Suining, and to the north is Guangyuan.

The Jialing River, a tributary of the Yangtze River, crosses the prefecture from north to south. There are another 30 rivers in the prefecture with a drainage basin of more than 30 km2.

The dams on Jialing River and its branches have a large potential to increase electric power generation. But the largest resource of Nanchong is human: Nanchong is one of the main providers of Chinese cheap migrant workers.

Transport
Transportation in Nanchong is quite convenient compared with other cities in Sichuan province because of its extensive express railway network, shipping, and air service.

Nanchong is a transport hub of the northeast Sichuan Province. It is crossed by the strategic China National Highway 318, built by the Chinese government in the 1930s, and China National Highway 212 and newly built expressways — Cheng-Nan and Nan-Guang expressway — which link the city to Chengdu and another prefecture-level city: Guang'an. The expressway to Chongqing is under construction.

The Dazhou–Chengdu Railway through Nanchong links Chengdu and Dazhou. The Chongqing–Lanzhou Railway, in 2015, will link Lanzhou (Gansu) and Chongqing, and turn Nanchong into a railway hub in northeast Sichuan province. The Nanchong railway station provides passenger and cargo services to regional and national economic centres such as Shanghai, Beijing, Chongqing, Wuhan, Chengdu and Shenzhen.

The old Nanchong airport was built in the 1950s and closed in 2003. The new Nanchong Gaoping Airport which has capacity to land bigger planes, provides regular air services to Beijing, Shanghai, Guangzhou, Shenzhen, Kunming, Xi'an and Sanya.

Nanchong is suggested as a tradition shipping hub in ancient times. Ships from Gansu could reach Chongqing along the Jialing river, but the river is not suitable for modern shipping.
