"Do your job that you have been contracted for, nothing more, nothing less"

We are in complete agreement, you have given good guidance. Just do the job you have agreed to do which does not include being a busybody and concerning yourself with Christian or even Atheist teachers and what they are teaching. I was merely pointing out that genuine Christians cannot help themselves from trying to convert others, as atheists are motivated by the same but opposite determination. Maybe the Chinese should ban Christians, it is their business to decide.
