还真是 越南还真是 一下来自 wiki The Vietnamese became independent from Imperial China in AD 938, following the resounding Vietnamese victory in the Battle of Bạch Đằng River.
The name Việt Nam (Vietnamese pronunciation: [viə̀t naːm]) is a variation of "Nam Việt" (Chinese: 南越; pinyin: Nányuè; literally "Southern Việt"), a name that can be traced back to the Triệu Dynasty of the 2nd century BC.[16] The word Việt originated as a shortened form of Bách Việt (Chinese: 百越; pinyin: Bǎiyuè), a word applied to a group of peoples then living in southern China and Vietnam.[17] The form "Vietnam" (越南) is first recorded in the 16th-century oracular poem Sấm Trạng Trình.[18] The name has also been found on 12 steles carved in the 16th and 17th centuries, including one at Bao Lam Pagoda in Haiphong that dates to 1558.[19]
