You ask the wrong question. And that is because you have no clue about language learning and teaching.
People like you are totally unfit for any teaching job, and I hope the Chinese can get rid of you somehow.
Time will work in their favour because who wants to employ a 68+ y/o fake any longer?

Being fair to you, I have to say that you do have a clue, but only a clue; and a whole truck-load of megalomania issues forth from having that one clue. However, in your case, abundantly blessed with clues or totally clueless is academic; you are not a native English speaker and shouldn't even be on the same platform as the likes of Beth discussing ESL, or spin-off matters concerning foreign teachers in China; except those foreign teachers teaching Russian or whatever your language is.

By the bye, I am not 68 and I do not have a student wife or girlfriend.
