I used to work in Shenzhen and paid social security for four years. Now I work in Shanghai. Can I transfer the previous social security to continue to pay?

First of all, tell you that you are not paying in Chengdu now, but opening a new account in Chengdu to pay, because social security is not connected to the internet now. I suggest you take out new insurance in Chengdu now. After enrollment, there are two ways for Shenzhen Social Security Association to handle it: 1. If you are in Chengdu for a long time, I suggest you transfer the social security in Shenzhen, because if you don't transfer it, the social security you bought in Shenzhen will be invalid according to the existing policy; 2. You are only in a short-term transition in Chengdu. I suggest that you can transfer or not, and then transfer when a place is stable. To sum up, mainly according to your specific situation, if it is convenient (considering that your previous work unit is still there, you can transfer from Shenzhen first, so as to save trouble later), merge Shenzhen with Chengdu first. The procedure is as follows: after you are insured in Chengdu, let your former company go to the social security bureau in Shenzhen for social security transfer. After the transfer, the Social Security Bureau will issue a transfer letter, similar to the letter of the social security payment account. After you get the letter, you can give it to Chengdu Social Security Bureau, which will ask you to fill out the relevant forms after receiving the letter. If the inter-provincial transfer is public to public, you will be fine. You just need to check whether the previous social security has arrived after a while. I hope it helps you,
