In BC 1 1 1, Emperor Wu of the Han Dynasty pacified Nanyue and formally established Cangwu County, which governed ten counties including Guangxin, Meng Ling, Mo Xie, Gaoyao, Duan Xi, He Lin, Fengcheng, Fuchuan, Fengyang and Lipu. Volume 28 of Hanshu records: "Ding Yuan, Emperor Wu of the Han Dynasty, opened Cangwu County in six years, called Guangxin, which belongs to Jiaozhou and has Lishui Pass." Lishui Pass is the entrance of Gui Jiang in western Wuzhou today. Li Daoyuan's Notes on Water Classics also recorded: "Lishui south to Guangxin County, into stagnant water."
Wuzhou is located at the intersection of Xijiang River, Yushui River and Lishui River. For 700 years, Guangxin has been the seat of Cangwu County. Among them, as a cross-toe secretariat, Jiaozhou's capital has a history of 300 years, commanding nine counties in Lingnan such as Nanhai and Cangwu, including large areas in Lingnan and northern Vietnam, and was once the political, economic and cultural center of Xijiang. According to historical records, Guangxin in Han Dynasty includes Wuzhou and Fengkai today.
