Zimbabwean, no degree, which visa can I apply for to be ESL teacher

Tae, based on what I know, a bachelor degree is needed when you apply for the work permit which is a necessary document for work Z type. Thus, I cannot tell you if you can get Chinese work Z type for sure. You can try to make the application from the China embassy. The required documents are your passport and copy of its data page, a completed application form, recently-taken passport-style photo, alien employment permit as well as other requirements.
