Dear Gao Fei, I am sorry to hear about your problem and thank you for your trust.I konw you impossible take his money.so do not afraid they suspect you as soon as you find him and clear it.Maybe you can find somebody prove your innocence.or you can also tell to your teacher and appeal all your classmates to find out the money。

In the word，facing it honestly and bravely is the key to finish it.I hope my advice is helpful and I wish you good luck. Yours truly, Aunt Betty
