Hi, I would like to know if some of you guy could give me some advice.

I have been dating this awesome girl for a while, and everything is great between us. She is Chinese and I am caucassian. The problem is that her father doesn't approve of the relationship, because I am not chinese.

Is there anything I can do? Everytime I meet him I am very polite and very nice to him. However, it seems that this isn't enough.

Any of you ever been in this kind of situation? got any tips?
thanks a lot!
