How to transfer the social security paid in Shanghai to Quanzhou after resigning?

If you confirm that Shanghai has bought social security, you can go to the Social Security Bureau to apply for a social security payment voucher. When you arrive in Quanzhou, you can hand it over to a new unit. When buying social security for you, just give your social security payment voucher to the local social security unit, and the social security units in the two places will handle the handover for you and won't let you run around.
