In reality to teach in China you do not really need a degree. Mostly you will be teaching Oral English and maybe children. A few months of self-learning and that experience you are getting now will help. But to get a legitimate working visa you will need a degree though.

In China laws are made to be interpreted according to the area. One law, for example, states that you must be over 25 to get a working visa. But next week my school will get a new teacher who is 23 years old. So you might get a legit visa from a place that has trouble getting foreign teachers.

I believe you can find work in China. Just make sure that the school knows that you do not have a degree. Don't use a fake degree. Also ONLY come on a Z visa. Do not get suckered in with comming on a business or tourist visa with the promise of the school to change it later. Either this school does not have a license to hire foreigners, or they want to check you out first to see if they want to hire you- at your expense of course.
