You can'rt stop them lying, and they most likely will continue to
do the ame what they did before. So it's up to the individual FT to do his/her homework
ans act accordingly.

Correct. Since current law results in passport seizure, huge fines, and deportation when teachers are lied to, it is thus necessary to avoid those places.

Since the teacher cannot get a visa without a sponsor, and the sponsors are lying to them, it is impossible to be legal.

Therefore do not teach there.

In the context of this thread, that would be to avoid working as a teacher in Shanxi, Sha'anxi, and most specifically at Yuncheng English Village.
