You just have that idea, but did not look for it online?
If so, you need to look for such a job online. After you plan to sign a contract with a Chinese school, they will issue you a work permit and an invitation letter. With them and some basic information, you can apply a Chinese Work Z in your local Chinese embassy.

The fee for the Work Z is 50,000XAF.

For the accommodation and the flight information, you may need to consult different schools.
