By the 3rd century BC, another Viet group, the [[Âu Việt]], emigrated from modern-day southern China to the Hồng River delta and mixed with the indigenous Văn Lang population. In 257 BC, a new kingdom, [[Âu Lạc]], emerged as the union of the Âu Việt and the Lạc Việt, with Thục Phán proclaiming himself "[[An Dương Vương]]" ("King An Dương"). Some modern Vietnamese believe that Thục Phán came upon the [[Âu Việt]] territory (modern-day northernmost Vietnam, western [[Guangdong]], and southern Guangxi province, with its capital in what is today [[Cao Bằng Province]]).<ref>{{Cite book | url = https://books.google.com/books?id=Jskyi00bspcC&pg=PA13 | title = A History of Vietnam: From Hong Bang to Tu Duc | isbn = 978-0-313-29622-2 | last1 = Chapuis | first1 = Oscar | date = 1995-01-01| publisher = Bloomsbury Academic }}</ref>
