REFERENCE: The Dong Son culture, Dongsonian culture,[1][2] or the Lạc Việt culture (named for modern village Đông Sơn, a village in Thanh Hóa, Vietnam) was a Bronze Age culture in ancient Vietnam centred at the Red River Valley of northern Vietnam from 1000 BC until the first century AD.[3]: 207 Vietnamese historians attribute the culture to the states of Văn Lang and Âu Lạc. Its influence spread to other parts of Southeast Asia, including Maritime Southeast Asia, from about 1000 BC to 1 BC.[4][5][6] The Dong Son people were skilled at cultivating rice, keeping water buffalos and pigs, fishing and sailing in long dugout canoes. They also were skilled bronze casters, which is evidenced by the Dong Son drum found widely throughout northern Vietnam and Guangxi in China.[7] To the south of the Dong Son culture was the Sa Huỳnh culture of the proto-Chams.
