Loading chinese font for the application

I had wenquanyi font file with whcih I should load the chinese font. I also had translator chinese.qm to install translator.

I successfully installed translator. But I couldn't load wenquany font.
I tried like QApplication::setFont(QFont("wenquanyi",10), true)

Can anyone tell me what is wrong and how can I do that?

Send me a font and I will try in my code to load it ... And try an alternative, try to use this font using stylesheets ...
