How can I apply for another teaching position in China if my degree is not notarized???

I am employed in China for the past 2 years. Agents inform me as of 1st April 2017 I need a notarized degree. I have a document from the Chinese embassy in South Africa 2015 when entering China, stating that I qualify for a Z visa because they recognized all documents required then to enter China, will this document be acceptable for new applications?
