Hi,
I have lived in Nanning on a college campus for over 1 year.
It takes time to adjust to life here so don't give up!
Of course the students are shy at first and it's up to you to make friends with them and with other people. If you're at the main Uni then try to 'mix' with the other teachers, they should know where to go locally. I find the people of Nanning very friendly, helpful and far from boring!
Plenty to do in 'The Green City' if you've got the time to explore this paradise. As for girlfriends etc, I've never met anyone yet who hasn't found the women of Nanning absolutely beautiful but treat them with the respect they deserve. Give it time ..... maybe you'll never want to go home like many of us!
