Nohow! 

Chinese Labor law (2017 novelty ...) states:

" ... holder of native English passport (USA, Canada, UK, Ireland, Oz, NZ und S. Africa) qualifies for the (legal) English teaching job in China ...".

Meaning of the legal ET job is "Working permit' with 'Z visa' for the first entry" ...

All other Chinese entry visas makes you illegal, if caught working as an ET.

You might receive illegal ET job offers, which I don't recommend 'cause you'll be abused by your potential employer and in the same time you won't be able to get protection from the Chinese authorities.

You will be also required to exit China every 3 or 6 months to renew your L (Touristy) of F (Business) visa.

1. Your Nationality

You must be from one of seven approved countries – UK, Ireland, US, Canada, Australia, New Zealand & South Africa

China has decided that only citizens from these seven countries speak English fluently and may teach their students. Yes, we know – it doesn’t always work like that but, to be brutally honest: their house, their rules.

2. You must be a native-English speaker

Very much tied to the first rule, and this one makes more sense, right? If you want to teach English to Chinese students, you’d better have a great grasp of the language. 

Saying that there is scant evidence to suggest teachers from French Speaking Canada or South Africans who speak English as a second language have problems getting a working visa.

Native English Speaker

In our experience, this is the most enforced of all the requirements that you need to teach in China, but not for the reasons you’d think.  It’s usually the schools that insist their teachers be native English speakers due to the fact that the students and their parents demand it.  If you’re a good teacher then the work experience might not matter so much, but if you can’t speak fluent English or have a thick accent, you will find it harder to get a job.

If your question is an example of your English ability, good luck 

An English speaker would ask the following question:

"How would I go about getting an English teaching job in China if I am a native English speaker?"
not
"How to get English Teaching Job in China? if someone is not native."
 

Your English is not good enough.
Brutal but true.
