I received a nice job offer from a University in China, but they asked me a reference letter that can prove that I have been working in a University before as teacher in the same subject I applied to the Chinese Uni.
I know the subject because I have been working in a Company(5ys) before, but I never worked as a teacher and for the Chinese Uni my Company reference letter it's not enough they want teacher exp too.

So my intention is to create a fake teacher ref letter and add the logo of my old UK University(where I Graduated) and sign it with the name of a Professor that it doesn't exist.

What consequences will I face in the likelihood my old UK Uni and the Chinese Uni will discover my trick?
