Historical geography of Vietnam

Jiaozhi (standard Chinese, pinyin: Jiāozhǐ, Vietnamese: Giao Chỉ), was a historical region ruled by various Chinese dynasties, corresponding to present-day northern Vietnam. The kingdom of Nanyue (204–111 BC) set up the Jiaozhi Commandery (; , chữ Hán: 郡交趾) an administrative division centered in the Red River Delta that existed through Vietnam's first and second periods of Chinese rule. During the Han dynasty, the commandery was part of a province of the same name (later renamed to Jiaozhou) that covered modern-day northern and central Vietnam as well as Guangdong and Guangxi in southern China
