Thanks for the advice Jan. I will definately e-mail my school's supervisor and tell him about the situation with my former head teacher. I would like to know myself if this is personal or sanctioned by the school. I just can not image the school would back this head teacher in trying to get me banned from China, since the school gave me a recommendation and release letter, and it would make them look bad with the Chinese authorities.

However, I do not really believe this stuff about getting banned from China. I am worried that the school might not pay my summer travel allowence.

Thanks, Stephen
