Social security is transferred from Shenzhen and then back to Shenzhen.

Legal analysis: Yes. It is possible to go back to Shenzhen in the future, so don't transfer the social security relationship yet. Shenzhen stops paying.

It is not too late to apply for transfer and merger after paying social security in other places and determining the long-term residence in the future, or determining the place to receive benefits before retirement.

After the social security payment is stopped, the original pension and medical payment amount and fixed number of years are still there and will not disappear.

Legal basis: People's Republic of China (PRC) Social Insurance Law.

Article 2 The state establishes social insurance systems such as basic old-age insurance, basic medical insurance, industrial injury insurance, unemployment insurance and maternity insurance, so as to guarantee citizens' right to receive material assistance from the state and society in accordance with the law in case of old age, illness, industrial injury, unemployment and maternity.

Article 3 The social insurance system adheres to the principles of wide coverage, basic protection, multi-level and sustainability, and the level of social insurance should be compatible with the level of economic and social development.
