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. It has also long been an important
military town of Sichuan. The old town of Langzhong is built according to
Feng shui principles. The dedicated military, trade and residential quarters of the town are located in a location corresponding to a particular element in Feng shui. The town itself is position centrally with respect to 4 mountains around it. 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. == Geography==
