Why the hell should anybody care if the guy is not in China working as an FT?

Professor, I don't understand your question. Mr. [edited] says he is in China working as a FT. After working at a Private School for two months, he has given it a positive review.

Christian missionaries are ordained and commissioned to proselytize, an illegal act for foreigners in China.

Students in classrooms are naive captive audiences. I care that my Chinese students are often subjected to stealth sermons by FT missionaries that choose to hide their identities and break Chinese law.
