Can Shenzhen Social Security Company return it without a certificate of resignation? How can I return it?

If you want to turn yourself in to the Social Security Bureau, you must have a company certificate, a copy of the original ID card, and a one-inch photo, and you must be yourself. This certificate is not your resignation certificate or application, but the company's application for surrender, which requires an online appointment. In other words, if you want to return to social security, you must have a company refund policy.
