Does Nanjing have to have an employment permit to pay social security?

Hello! What you said is normal. You are insured after graduation on 20 10. As long as you have a graduation registration certificate, you can participate in the insurance, and you don't need an employment unemployment certificate. To transfer to Shanghai and return to Nanjing to participate in the insurance again, you must have an employment unemployment certificate. It is still very simple for you to take your ID card and household registration book to the street social security office where your household registration is located.
