Langzhong is a county-level city in northeastern Sichuan, China, located on the middle reaches of the Jialing River. It is administered as part of the prefecture-level city of Nanchong. Langzhong has a total population of 840,000, with 200,000 residing in the urban area.
The site of present-day Langzhong served for a time as the capital of Ba, a native but sinicized Sichuan state during China's Warring States period. It takes its present name from its role as the seat of Langzhong County, established by Qin two years after its 316 BC conquest of Shu and Ba. Under the Han and Tang, it was an important center for astronomical research. Under the Yuan, Ming, and Qing, it was known as Baoning. Over the late imperial period, it served as Sichuan's provincial capital for a total of ten years. It was well known for its salt wells.
Since 1985, the PRC government has awarded Langzhong with various accolades on three separate occasions. In 1986 the State Council named it a famous and historical town. In 1991, it was finally upgraded to county-level city status.
Langzhong is located in the northeast of the province and the northern part of the Sichuan Basin on the middle reaches of the Jialing River.
