Well mate if you pay this Grace Kappa the two fees of 2000 yuan each, well you have just bought yourself a giant piece of the Great Wall of China. This is an old scam and any old timers in the ESL game will tell you that you never pay a fee to any recruiter, never! If she is a real recruiter she has been paid a deposit to go out and recruit a foreign teacher and the school will pay her the final fee when you have signed on to what ever school it is that she is working for. So do not take her up on this wonderful offer that she is giving you. Try dealing directly with the school and cut out the middle man. Good luck in finding a school
