Hi Justin.

I was just looking through the posts here and saw yours and also some of the replies.
China can be a very hard place if things are not going good, no work, little understanding of the language and culture, to name a few.
you need more money than what you propose taking, you don't have a signed contract so there could be one problem there.
your taking too many clothes with you too. but money and somewhere to live are by far the two most important things you will need.
I took some months to plan my first trip and even then, I was not ready when I came to China.
hospital medical insurance is another important thing, many Chinese people dread to have something life threatening wrong with them becauase some medical bills can be so expensive. the poor have very little or no money and simply wait for death.unless there are family or friends who will help.
it certainly can be very hard and unforgiving if one is not prepared.
I hope your trip will prove rewarding and things will work out very well for you.
Good luck.
