You can only transfer in the same province, otherwise you can't participate in the new insurance.

As for whether the intermittent part is compulsory or forbidden, it depends on local regulations. Even if it is not paid, the endowment insurance paid in advance is your own and will not be invalidated. The eligibility for receiving pension stipulated by the state includes "cumulative" contributions 15 years, rather than continuous contributions.

If it is a transfer, open a "basic endowment insurance payment voucher" to the insured institution of the original unit and hand it over to the manager of the new unit, who will then hand it over to the social security, and the social security will go through the transfer formalities.

If you are not sure, please call 12333.

good luck
