China Tefl Network is one of the worst companies not only in Hangzhou but also in China,The company is blacklisted in many provinces , and it has a bad name even between Chinese people,

They offer the foreign teachers the z visa which is quite good but they will never fulfill the terms and the conditions of the contract,The have nice trained recruiters , they speak in a nice way , using sweet words but actually , most of them are liars, My experience with them was horrible,The first thing that they did to me is to send me my documents to my home country by DHL but they never advised me that they will deduct the DHL fees from my salary,Sometimes they delay the payments and they pay me on a different payday ,Most of the houses that they rent for the teachers do not cost more than 1000 RMB for the rent , but actually they mention on the contract that it costed 2000 RMB,

They try their best to deduct money from your salary as much as they can , some teachers might not get insurance from the company, which is quite dangerous,

And the company does not care, finally when you finish the contract they company will not provide you with a release letter or a recommendation letter, that means you will not be able to extend your residence permit with another school , and finally you will return back to your home country ,

My advice to you never ever to sign a contract with them ,as it is like losing money and time
