Taiwanese indigenous peoples [SEP] Surnames and identity
Several factors encouraged the assimilation of the Plains Aborigines. Taking a Han name was a necessary step in instilling Confucian values in the aborigines. Confucian values were necessary to be recognized as a full person and to operate within the Confucian Qing state. A surname in Han society was viewed as the most prominent legitimizing marker of a patrilineal ancestral link to the Yellow Emperor (Huang Di) and the Five Emperors of Han mythology. Possession of a Han surname, then, could confer a broad range of significant economic and social benefits upon aborigines, despite a prior non-Han identity or mixed parentage.
