You decided to home in on a typing error! Have you nothing to say about that f-visa post?

I feel I have upset you for something else? Now come come, what do you say about teaching on
F visas?

I say it's foolhardy to teach illegally in China these days, as you and I know very well. Why foolhardy? Coz of the severe penalties that those illegally employed FTs will be subject to, if found out.

You should not imply that it's ok to teach on an F visa. You never know whether your implication will be believed by some happy-go-lucky foreigners. And as a result they might end up in HOT WATER!
