Just go or just come over . Since you said that the bad reviews sounded like anger what's there to stop you. As for the US15.50 per day, it depends on where you are going to teach. For small cities it will be sufficient to live comfortably provided you don't spend lavishly on food and other needs.

You have to make sure that accomodation is not shared and utilities are all paid for. Some schools do provide excellent medical facilities but some have facilities that are disgusting. Warning!You may need to bring loads of antibiotics with you. Here in China most doctors will stick a needle into you - IV, for whatever little ailments that you have.

For the 24 hours support, some good employers or agencies may provide that (rarely) . Others can be describe as Houdinis- they take their fees and you will be left to rot in some shitty holes in the middle of nowhere.

Do not get put off by what I've said. You never know, you may end up in one hell of a good school and with an agency that really take care of their staff.

Good luck
