Man-To Hui (許文韜)

(Wentao Xu officially used and personally used before, pronounced in Mandarin Chinese)

According to my paternal grandfather, I am a descendant from northern Viet Nam before Ming Dynasty, during which my ancestors migrated northward to Guangxi, China, where they remained and graudally intermixed with the Han people ever since. If this story is reliable, then it is likely that my ethnicity is partly Gin (京 in Chinese, Kinh in Vietnamese). However, the pedigree records nothing about this part of history, but says that we were Hoklo immigrants. Taking into account that faking pedigrees was not rare in ancient southern China, because then the Han people were considered superior to any other peoples, I am totally confused. Nevertheless, none of my paternal relatives nowadays speak the Gin language (a dialect of Vietnamese) nor Hokkien. They all speak Hâm Lim Yuet (粵語欽廉片). Since I was born in 1990 in Canton, Guangdong, my first language is Cantonese, the most influential dialect of Yuet. By contrast, my maternal pedigree is much less uncertain. They are definitely the Hakka people (客家人).

Now I am a graduate student of EPSS, UCLA, working with legendary David Jewitt.
