The BIGGEST and most serious issue that FTs in China have to deal with is the inability to share experiences on such forums as this one for esl sites are sponsored by the employers, recruiters, tesol/tefl and invaded by varieties of questionable users. So, given my previous input vs yours, you've proved my obvious point.

A BIG serious issue that FTs in China have to deal with are dishonest schools and the employers who run them. The cultural side of this is to understand Chinese business "culture" and how to deal with the latter. Given your previous input, you don't seem to know anything about them either. You must also be unemployable in your home country for obvious reasons and cannot do anything but to sell yourself to dishonest employers in China. And this is what losers do. Yes, loser!
