I have been reading all your posts. I worked for tianshuo for a little more than a year, how dumb was I to believe they would cancel my visa, and that they would put the police on me. But those were all lies. lets name them:

MAGGIE
MAMA WANG
LUCY
(and KIKI who is in jail now, because they bailed mama wang but they didn't bail her out)

I had to leave china and get a new visa again, this time with a working permit and an invitation letter, so read carefully : DONT TRUST ANYONE WHO TELLS YOU TO COME TO CHINA JUST WITH A TOURIST VISA AND THEY WILL CHANGE TO A WORKING ONE THERE. IT IS A LIE: in order to work LEGALLY in china you MUST have an invitation letter and working permit, this last one is only provided by each province's government, and no one else.

I have seen it all: tianshuo went from having more than 150 teachers to have less than 10 at the present day. Why? lies, lies, and more lies. I have been refused to get my salary, and to get my passport back. I had to call my embassy. Everything was broken in those sewer-stinky apartments, and for god's sake never ever trust chinese handymen. Nevertheless, I have seen hard-working easy-going adult people (+60 yrs old) getting f*cked around by these people for months, even years. I have seen how those assistants they hire for no longer than 3 months do all the dirty work for them, and when you go to complain to the boss, they all dissapear (including the boss).

Ill cut the crap:

I never got a full schedule, not even 20 hours a week.
I never got a full salary, they would be always stealing money from me.
I never got that famous "release letter".
When I left, they chased me around the city saying that I owed them money (regardless of the fact that they didn't pay me my last salary).
and so much other crap that I don't want to remember.

be aware of your chances before coming to work in china.
