I agree, but I am just curious as to what extra visa privileges you get for being married?

1/ Long L visas issued within China.
2/ When with your wife, you can stay in cheaper hotels that are licenced to accept Chinese only.
3/ Some Chinese EFL employers prefer hiring foreigners with Chinese wives rather than single foreign men.
4/ Less chance of your employer trying to cheat because he (or she) is aware your wife is with you.

In fact, there are precious few extra privileges. But the long L is the best one for me. A 5-year RP would be equally advantageous, if not a little more useful.
