Chinese : there are two sources of this surname, both from the Spring and Autumn period (722–481 bc). At one time, there existed a state of Dai at one time (in modern Henan province). When this was defeated by the state of Cheng, residents of the defeated state adopted Dai as their surname. Additionally, a duke of the state of Song was called Dai, and his descendants adopted Dai as their surname. Vietnamese: unexplained.
