Still I’ve never heard any Chinese folks introduce themselves as ‘an Asian’. In fact I’ve never heard any ‘Asians’ who were born and live in Asia call themselves ‘Asians’.
I feel it perfectly understandable. After all, when’s the last time you actually heard a ‘westerner’ call him/herself ‘a westerner’? They are Brits, Americans, Aussies. Or, more likely, Tim, Emily and Steve.
