My household registration is in Pengshan, Sichuan. After working in Chengdu, the company bought me social security. Now I quit. How to renew social security? Can I buy my own medical care and pension?

Medical care and old-age care can be paid by yourself, directly at Pengshan Social Security Bureau (Caijiashan Zhiweixuan there). You can ask the original unit to open a social security payment voucher for you at the Social Security Bureau, or you can go to (West Street) by yourself. Open a social security acceptance letter at Pengshan Social Security Bureau with the voucher and turn it to the original. In addition, you can ask whether Chengdu can issue a payment certificate, and Pengshan can immediately continue to pay and enjoy medical insurance benefits. However, medical insurance policies vary from place to place, so ask clearly first.
