In 1960, local government officials tasked with cleaning up Qing-dynasty archives found
4000 Qing-era official documents in a watchtower of the county's
public security bureau, covering political, economic, military, cultural, educational, judicial, religious, and diplomatic records of the years 1656 to 1911. It is one of the largest surviving collections of Qing-era judicial material. The archives are nowadays stored by the Nanchong Municipal Bureau of Archives. ==Administrative divisions==
