When Chinese, Koreans, and possibly other Asians migrate into countries like the UK or the US, they often take on a "western" or "anglicised" name for a number of reasons. For example, the director Justin Lin's Chinese (well, Taiwanese) name is Yipin Lin. I'd like to know how to refer to the two variants:
Yipin Lin is his ____ name while Justin Lin is his ____ name.
Ideally, I'd like to avoid nationalities (Chinese/Korean) and regions/languages ("western"/"anglicised") in preference to generic terms.
P.S. I want to avoid connotations of replacement as both names are often equally valid and current.
