In China he keeps a small mustache!
You like it... or... not.
I find it a little bit weird as most Chinese people don't have many facial hair and usual shave well.
Is there a new fashion in China?
We can ask ourselves wether it is positive or negative not to shave, wear a beard, a mutache when you are a foreigner in China?
Personnaly I think that a foreigner is always seen as a foreigner by most Chinese people. This implies a number of positives or negatives clichés.
Thus you should play on this foreign image fully and forget to shave!
