Ask! What is the most reasonable way to deal with the social security paid in Shenzhen before going to work in Shanghai?

It is enough to make a social security list in Shenzhen and bring it to Shanghai for transfer. When you go to the scene to handle the specific list, the staff will understand what it is for you. Bring your ID card.

In addition, if retirement is still early, there is no need to hurry. When you are nearing retirement, it is enough for you to decide where to go after retirement. Moreover, the future big data networking may not need you to deal with it.

Repeated payment is not acceptable, and the social security bureau will not recognize it. So the payment in Shenzhen will be cut off soon.
