Question should read:
Why do all Chinese people have/possess the same (facial) characteristics?
OR
Why do all Chinese people look the same?
...same eyes, hair, skin colour, (not only Chinese people but all Oriental people) etc.. Am I right ?
Do they think so too?
By the way, I'm sorry if my question has offended you.
I used to think the same thing, I thought that all Chinese, Japanese and Korean etc. people look the same and found it difficult to tell them apart but, after living in China for over 4 years I've come to realise the obvious - they are not alike at all.
Yes the hair and eyes are the same colour BUT skin colour varies ALOT, and of course, the facial features themselves are completely different from person to person.
And, as many have mentioned already, they think all westerners look the same too...
