Your question did make me wonder for some time. You are a Chinese girl, aren't you? I reckon there is no much noticeable difference between Chinese people living in Beijing and in your region. However, the words you employed in the question, 'people in Beijing' is quite interesting. You seem to imply Chinese residents rather than Chinese citizens. As Beijing has now become a great metropolis and attracts people of different kinds from over the world, it is hard to briefly describe what people in Beijing look like. I guess, maybe, varied kinds of looks?

They have chinky eyes... And the average people are smaller than we thought.. :))

For me i can't make diferent between them bcz all have the same shape of face (eyes,small,nose..)

They all look very Chinese to me.

open-mind
