Where in China are you going?
What is the TEFL certificate are you completing?
Yes, being anything but a foreigner trying to teach English in China (in my case Hong Kong) is a negative, but fear not, there are still opportunities to be employed. It just depends on whether you're willing to do them. Try applying to schools nonetheless, you never know what may happen. Tuition centres (not the tutor kings/queens) have vacancies all year round so you shouldnthave too much of a problem.
So how can we make ourselves more employable?
Get a recognised PGCE plus 2-3 years teaching experience In a local school(say from the UK). This makes you extremely employable and you'll surely get a satisfying salary with government incentives.
Or, find some teaching experience in the UK. Private tuition perhaps or even youth volunteering work.
If you're thinking of teaching kids, try taking a phonics course (especially Jolly phonics)
