If Helen group got you the z visa and the resident permit in China,

The first thing that they will do , they will ask you to pay for your transportation fees, medical check fees, and to find your own accommodation if they do not have a place to accommodate you , till they find you a school, and by that time you might rent a room in a hotel that might charge you 200 RMB per night, and they will never care

They will keep your foreign expert certificate and they will never let you see it,
They will deduct the DHL charges from your salary , that is related to your documents when they send it out to you by post to apply for the z visa from your own home country,and they will never inform you that,

They will never pay you on time, and there is always a delay on the payment,

They will hide everything from you, even the original contract they will not give it to you,

The companys' vice managers principles are like this,

Foreigners do not worth anything, So treat them like dogs, we have their documents we have everything, they are poor , they came to China to teach because they need money,

This is the way that they deal with foreigners,

Helen Chen, Hangtao wu, Shirly , you will hear those names always in the company , they are the managers who are responsible for all of that hassle,

The company is a blacklisted company in Taizhou, and one of the companies that has bad repetition in China, and it is famous for it is bad name,

Once you start complaining, they will threaten you saying that they will cancel your expert certificate and cancel your resident permit in China,

You just need to do one this just contact with the government on
