: You did an end run around me when you first did your contract and ended up signing for less money than I would have arranged.

Typical unethical training center tactics. They'll cheat not only the rich Chinese, but also dumb laowei who work for them.
Real providers of education do not negotiate salaries. There are fixed regulations re somebody's salary, based upon academic qualifications and teaching experience, among other criteria. You accept or decline the initial offer made by the employer. Your company treats jobseekers like Chinese shoppers bargaining at a non-governmental department store, pathetic. Your outfit has no integrity!
