I am part of a heavy drinking and high end living ex-pat crowd. I mostly mix with ex-pats who like the same lifestyle as myself. Some of them are married, but it was mostly so they don't need to do visa runs. I have not married a Chinese woman in my now six years here, as I don't see any advantage in doing so. I can only see disadvantages, like being asked to buy a house and car, which I don't want to do in China. In my experience, married foreigners in China are the most smug and arrogant, although some are not. What causes this arrogance? It is hard to say.
