Lạc Việt
From the 3rd century BC the term was used for the non-Chinese populations of south and southwest China and northern Vietnam, with particular ethnic groups called Minyue, Ouyue, Luoyue (Vietnamese: Lạc Việt), etc., collectively called the Baiyue (Bách Việt, ; ). The term Baiyue/Bách Việt first appeared in the book "Lüshi Chunqiu" compiled around 239 BC. By the 17th and 18th centuries AD, educated Vietnamese apparently referred to themselves as "nguoi Viet" (Viet people) or "nguoi nam" (southern people).
