Guanghan was Luo County in Qin Dynasty. Luoxian county is named after Luoshui flowing through the county, so the old city is located in Wuli Lane, a rural area in the north. In the 12th year of Jianwu (38 years), Emperor Guangwu of the Eastern Han Dynasty restored Yizhou and Guanghan County, and Luoxian was Guanghan County. Here, it means "the vast Han River". Qianwei belonged to Shu County in Qin Dynasty. In the sixth year of Jianyuan (BC 135), Emperor Wu of the Han Dynasty established Qianwei County as the national title. Qianwei county has a long history and excellent living environment. Since the Yuan Dynasty was established in the sixth year of Emperor Wu of Han Dynasty, Qianwei has been included in the history of China, and Emperor Wendi of Sui Dynasty has been emperor for three years, following the name of counties. Since then, although the county has been moved and expanded several times, the county name "Qianwei" has been retained for 14 16 years.
