Troublemaker, do not let your husband go back to China. I know this opinion is of extreme nature, considering that I do not know either of you, but having gone through what I have gone through, I can tell you that marriage and kids is mre important than career and money. few people can resist temptation, and it is the fault of you to subject your husband to temptation.
Good luck with you. Just remember, money is not necessarily a good thing anyway, especially if it's not accumulated slowly.
