Inquiry on the Z visa/ work permit

I have a degree in Education from Gulu university and I have been invited by one of the school in Shiyan but according to Z visa requirements, I am supposed to be a Native English speaker to teach in China, so please what I am suppose to do. Is there any way I can get a Z visa/ if not what is another option for me. Looking forward to hear from you
Thanks
