How to transfer social security to a new company by changing companies?

1. Social security relationship transfer can only transfer pension insurance, medical insurance and unemployment insurance.

2. We need to see whether the new job is acceptable before we can transfer. Medical insurance and endowment insurance can only transfer the amount of personal accounts and the number of years of payment. The full transfer of the personal part of the endowment insurance will not affect the interests of the insured's personal account, regardless of whether the unit pays the part or not. This is only the fund balance of the social security institutions of both parties.
