Ok, I know I'm waaaaay too late to ask, but how can we be sure Chieko is Japanese? Because she was first sighted here in Beijing; this is one clue. The second is she works at a Chinese restaurant. Third, she knows Chinese medicine.

So what makes her look Japanese at a glance without hearing her speech or any verbal clues?

BTW, what differenciates Chinese ppl from Japanese ppl in terms of appearance (besides those school uniforms)?
