I would like to warn people about a agency located in beijing I have done some work for. They like to call themselves the 'English teacher recruitment project' or the English speaker recruitment project, Other names they use are Tongwen, and Sijifengxing which is their actually registered name. Although they are not registered as a teachers agency. Sijifengxing is owned by a Mr Gao who is an unscrupulous person. Recently he had several other partners in the business but they have all left now due to his practises. Which include Non payment of teachers salaries, Lying about living conditions and on several occasions even threatening teachers who complian with violence and even death. I would urge everyone to steer well clear of these people. they will promise to 'help' with visas but what they acually mean is they will charge YOU anywhere up to 13,000rmb for a fake visa which is almost 3 months wages on the poor salary they offer if indeed they pay you at all.
There are plenty of other companies that will genuinly look after you well and pay for your visa. So please go with them.
