The key is being persistent, patient and lucky. If money is most important to you, you had best look first for a China job in the States or from Hong Kong. Any company that sends you overseas will most likely give you a full package plus great benefits. Even if money is not important to you, before you leave the States you ought to do a heavy job search on that end. See details on compensation below.
Many people come and then look for a job.
It's probably the true China person who chooses this riskier strategy. We do advise you to first look in the States, though, or in Hong Kong, before packing your bags. Hong Kong can be a prime job market, but unless you have a friend there, it is very expensive to stay and hang out. Maybe you get a good job in Hong Kong and they send you into Mainland China. Be prepared to be patient and not find a job for several months.
