A good post.

The brit guy I know doing it, does not even like teaching kids. He more or less admitted to me it is just easy money, but he dislikes the work, and that his wife is the driving force. His wife wants to go to the UK eventually, he does not, looming problems, she could take the money and flee and all his work and time will have been for nothing, it is better not to marry a chinese woman in her 30s or 40s....not unless she shows willing, financially. Good luck.
