雒越
The Âu Việt, known in Chinese as Ouyue, resided in modern northeast Vietnam, Guangdong province, and Guangxi province. At some point they split and became the Western Ou (Xi'ou or Nam Cương) and the Eastern Ou (Dong'ou). In the late 3rd century BC, Thục Phán, a descendant of the last ruler of Shu, came to rule the Western Ou (Xi'ou or Nam Cương). In 219 BC, Western Ou came under attack from the Qin Empire and lost its king. Seeking refuge, Thục Phán led a group of dispossessed Ou lords south in 208 BC and conquered the Lạc Việt state of Văn Lang, which he renamed Âu Lạc (Ouluo). Henceforth he came to be known as An Dương Vương.
