Visa on arrival for South Africans

Hello. My name is Anthony. I am currently stranded in South Africa with no form of Income. I am about to lose my job in China too. I have a valid resident and work permit in China. I am desperately trying to get a new Visa issued to enter China and return to work. Does anyone know if I will be eligible to get a Visa on arrival? Or is there any other way to get a new Visa issued?
