Not sure the way Chinese girls measure guys goes by nationality, but my guess is that if it was – Pakistan wouldn't be too high on the list. Still, that maybe shouldn't stop you from pursuing the option, there are lots of girls out there with different personalities, tastes, etc, so you can never know. I knew a Pakistani guy who studied Mandarin in Taiwan who found himself a gorgeous Taiwanese girl and they both moved together back to Pakistan and lived with his parents after getting married. As far as I know, they live happily ever after.
