No question it's photoshopped.

Those legs are freakishly long and skinny.

Have to wonder the OPs motivation in posting this.

Maybe the poster has airbrushed his girlfriend a little, but that doesn't detract from his message.

The poster's motivations are clear, he wants to make it clear to women-haters that Chinese women can make very nice girlfriends and wives irrespective of their financial status. However if one spends all one's time frequenting whore house in China you won't get a nice Chinese woman to practice your airbrushing on.
