Offering more commuting choices and raising pay would be the trend for airlines in China to attract expat pilots, as well as improving their internal system to understand, communicate and help expat pilots if the management awares.
The past 7-10 years were the first time that China aviation inducted expats into this field. It was pain for both airlines and expat pilots to get to know each other. I should say recent years things are getting better in most of the airlines.
Though culture, language, lifestyle...in China are quite different from Western and there are many headaches in work, expats could lead a happy life if he's willing to make friends and being kind and optimistic. I believe some captains posting in this thread do know China well and deal with things well.
