Lưu is a Vietnamese name of Chinese Han (漢人) descent. Between changes in Chinese dynasties and regimes, there were several major Luu/Liu (劉) families who immigrated to Vietnam. An example would be the Shu Dynasty where Emperor Liu (Luu) Bei's (劉備) descendents left their capital in Si Chuan. After losing to Wu and Wei dynasties in the Three Kingdom Era, many royalties and peasants alike headed south and eventually escaped to Vietnam. Another major immigration period is in 1949 when the communist took over China and many loyal nationalist left to Vietnam. Prior to French occupation, Vietnamnese writing was in Chinese character (漢字) and Luu was written as 劉. After French occupation, alphabets were introduced and hence all Liu (劉) surnames were changed and spelled as Luu. Many descendents of Luu who speaks Chinese would spell Luu in English and writes 劉 as their Chinese surname. After Vietnam War in 1975, many left the country and resettled all over the world. The majority resides in France and the United States.
