In 111 BC, Han troops invaded Nam Việt and established new territories, dividing Vietnam into Giao Chỉ (pinyin: Jiaozhi), now the Red River delta; Cửu Chân from modern-day Thanh Hóa to Hà Tĩnh; and Nhật Nam (pinyin: Rinan), from modern-day Quảng Bình to Huế. While governors and top officials were Chinese, the original Vietnamese nobles (Lạc Hầu, Lạc Tướng) from the Hồng Bàng period still managed some highlands.
