"Get on the track"

It seems you are off the rails. [edited]

I would not allow you to teach my children English.

Once again I will state, have a look at the job advertisements for English teachers, they want native speakers.

Question; If you want your children to learn chinese, will you seek out a chinese person or a Mexican?
Question; If you have desires to learn to cook fine Japanese cuisine, will you ask an Egyptian or a Japanese person?

You are not getting English teaching jobs in china because you are NOT a native speaker. It has nothing to do with the colour of your skin.
