Teach English in China. A Citizen of Trinidad and Tobago. What VISA do I need? Is this possible

I would like to Teach English in China. I am a Citizen of Trinidad and Tobago. What are my chances of teaching in China? What are the requirements for a Z type? What are the requirements for a F type? What are the requirements for a Ltype? I am a qualified Teacher in Trinidad and have a Bachelor's Degree together with a TESOL Certificate. Trinidad is an English Speaking former British Colony country. Would I be able to get a Z type to teach in China?
