I know for a fact that if you're not of chinese background, you will NEVER be accepted as one of them.

That's true. Gregarious laowai will feel very lonely over here. But if you are a loner or someone with very few real friends back in your homeland, you'll be able to cope here well. Otherwise, don't come.

Another thing to be aware of is that there's always an angle to any Chinese who go out of their way to befriend you. It will probably be money-orientated, eg free tuition from you or getting you to teach where there's a commission that you don't know about pocketed by your Chinese new-found friend, or acting as your agent/interpreter in a pink room for a commission.

As for Chinese women, those mousy types will never get involved romantically with laowai. You'll 'attract' golddiggers by and large. You don't want to be a meal ticket bossed around by such a woman. There are suitable wives here, but it's not easy to find them. The main thing is to ensure you're the boss in the marriage, not her!
