How to transfer social security from Zhanjiang to Shenzhen?

Old-age medical insurance can be transferred. You only transfer the amount in your personal account. After the transfer, you should recalculate your contribution index according to the local social wage. If you transfer from an area with high social wages to an area with low social wages, your contribution index will increase. If you move from the low zone to the high zone, the contribution index will decrease, but if the average pension contribution index is lower than 0.6 according to the social security regulations, it will be calculated as 0.6. From this point of view, when you are working in a social wage, it is the most cost-effective to transfer to a region with high social wage, and the amount transferred to a personal account in any region will not change. If your payment period in Shenzhen is 10 years and only 5 years in Zhanjiang, you can transfer the payment from Zhanjiang to Shenzhen and apply for retirement in Shenzhen. The pension is higher than that in Zhanjiang. If you have only been in Zhanjiang for 5 years, you can't transfer back. Of course, if it can be transferred back, it will definitely be higher than the pension paid by 15 in Zhanjiang. As long as you only pay 15 years, you will retire. Your payment index 1 is no different from 0.6. They all take the lowest local standard pension, and the same standard pension in Shenzhen is definitely higher.
