Hi
Haha, you've got very sincere replies really.
I 've only passed through Tai Yuan. I believe it's a Confucian county and you'll find pretty conservative Chinese around there; but then, you might find big surprises too.
Your concern's understandable and your wish to find other expats too, as Tai Yuan's a place that sounds like you're going there to do missionary work; like Gladys Alywards went to Yang Zheng ( also in Shanxi?) in 1931 and became a close friend of the local Mandarin who appointed her as an official foot inspector ( culltured Chinese ladies had their feet bound in those days).
Some expats work in cities like Bj and S'hai where they're spoilt for expansive expatriate company ; but you can make friends with locals more easily if you're rather isolated.
Depends on what experience you're looking for in China; but, like everything else in life - you can find ways to adapt or make changes that will suit you. I believe your company and colleagues will look after you well if you're working for a reputable firm or school. It's useful to join societies or clubs related to your interests - you'll find like-minded friends.
Good luck and hope you'll have a great time in China. I know many of my friends did - in the 80s and before! From my own short stays, i found it easy to get teaching English jobs ; and Chinese students simply adorable then; can only hope they're still the same nowadays, with all that emphasis on business and success these days!
