Anyway, life goes on and we just want to let our supporters and friends know that we are no longer at MEGA, and remind new comers to beware of contracts and agreements signed locally in China, they don't mean ANYTHING.

But to me, as an employee, THEY DO MEAN EVERYTHING, and I ensure that my employers get to know I'll take them to hell's gates, if necessary, to make them adhere to the terms and conditions of my contract with them.
Of course, I wouldn't sign a contract that is not a SAFEA one in the 1st place. That's why I'd never teach at many private schools nor training centres in China. I needn't risk being taken for a ride. At least, the public sector here has a modicum of integrity, and it's VERY welcome at that!
