Administration
In 111 BC, the Han Dynasty armies defeated the successors of Triệu Đà and incorporated Nam Việt and former Au Lac into the Han empire under the new name of Giao Chi, dividing the former kingdom into nine commanderies:
- Nanhai (南海; Vietnamese: Nam Hải; located in Lingnan, modern central Guangdong)
- Hepu (合浦; Vietnamese: Hợp Phố; located in Lingnan, modern southern coastal Guangxi)
- Cangwu (蒼梧; Vietnamese: Thương Ngô; located in Lingnan, modern eastern Guangxi)
- Yulin (郁林/鬱林; Vietnamese: Uất Lâm; located in Lingnan, probably Guilin, modern northeastern Guangxi)
- Zhuya (珠崖; Vietnamese: Châu Nhai; located on Hainan)
- Dan'er (儋耳; Vietnamese: Đạm Nhĩ; located on Hainan),
- Jiaozhi (交趾; Vietnamese: Giao Chỉ; located in northern Vietnam and part of southern Guangxi)
- Jiuzhen (九真; Vietnamese: Cửu Chân; probably located in central Vietnam)
- Rinan (日南; Vietnamese: Nhật Nam; probably located in central Vietnam)
All nine districts were administered from Long Biên, near modern Hanoi; each ruled by a Chinese mandarin while the old system of low er rank rulers of Lac Hau, Lac Tuong were kept unchanged.
