Why should I learn the language? Should I learn the language of every country I visit? Where would I have found the time to learn so many language? I would argue that knowing how to speak mandarin will only expose you to even more of their deceptive ways. If you cannot understand them then they cannot lie to you as often as they would like. On the other hand if you can understand them, then you will be subjected to even more of their nefarious behaviour.

Whether they tell you about "free accommodation" in chinese or English does not matter, they will still be lying to you. Whether they tell you that you working 15 hours when in fact it will be 20 hours, does not matter what language is spoken, its still a lie. They will not change their behaviour just because you can understand them, they will be forever the most dishonest society, whether you can speak their language or not.

That has to be one of the most stupid statements I have ever read on this site.
Fact; They are still going to lie to you in English, mandarin, cantonese, or Zulu!!!!!!!!!!!!!!!!!!!!!!!!

To suggest Ronnie is daft because he/she has more than one questionable employers whilst in china is completely unfair. It is a daily occurrence to come into contact with questionable chinese, employers or otherwise.
