Maybe more than half of FTs working in China are doing illegal work. You only have to moonlight for 50 minutes a week at a different school and you will be treated the same by the police as the man with no expert's certificate at all. Certainly morally you won't be superior. Not you, not talking about you personally.

True! Anyway, good luck to those foreigners. Hopefully none of them will be apprehended by the police.
