San Diu people

The Sán Dìu (also known as San Deo, Trai, Trai Dat and Man Quan Coc; ; Chữ nôm: ; Vietnamese alphabet: Người Sán Dìu) is a Yao ethnic group in northern Vietnam who speak Yue Chinese (Cantonese), a Chinese language. Although the Vietnamese government classifies San Diu as an independent group, San Diu people are originally a part of Chinese people in Vietnam. They are believed to have migrated from Guangdong, China around 1600.
