For real, there were an evangelical yank couple in Wuhan like a decade ago that were there teaching English at one of the universities and would hand out Christian children's books to these young adult Chinese university students. The students knew it, the other English faculty knew it (a Kiwi, a different American couple, and even the other American Christian, all disliked the couple). They thought they were saving the souls of the poor godless Chinese by having extra, optional study sessions that just so happen to be like youth pastor reading material. Got upset some of the other teachers wanted to have a Halloween party with the faculty/students.

Good times.
