I have no depolima and degree how can apply China working visa

Hi, 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 give you a definite answer. Just give it a try. Good luck.
You should first prepare those documents including your passport and copy of its data page, a completed application form, a recently-taken passport-style photo, work permit (your employer will get the last document for you). Then, submit the application to the CVASC in your country.
