It's a good thing they made her oriental/Chinese. I pictured her much differently. So, she's a lot like Luna Lovegood, the actress being from Ireland.
They put Chang in with the minor characters http://en.wikipedia.org/wiki/Hogwarts_students and Luna as her own article already.
This is interesting to me since I'm 1/2 Chinese and 1/2 Irish.
I mean, I feel pressured to have to want to be Cho, moreso being 1/2 Chinese. I do not really want to be any of the characters in this story. (I have read 1 - 5 and started 6, so far.) None of these characters are at all like my life, reflected. I think, it is because I am from a different country. Well, I am from U.S.A., Florida.. I think Cho was a great and innocent character at first, but I got disgusted and shocked whenever she'd left Harry. All the characters are stupid sometimes, but this was waay stupid. I hope it is not a racist joke by accident. They wanted a person with an "asian" personality and they got it. England = Ireland now, as well. I think what happened with this character is she got so physically outdone with life, There, that Harry really was hurting just her sensitivities. I do no think she was being racist.. in that regard. You know, it is that physical feeling that you cannot be with a person before something is really too late.. She just did not fit in, at all.
