Is there a time limit for social security transfer? What are the procedures for transferring in different places?

The following program: 1. Print payment voucher. Before the insured person leaves this city, he/she should take the original and photocopy of his/her ID card to the Social Security Bureau of this city or the social security offices of towns (streets) in this city to print the payment voucher for his/her participation in this city. 2. Apply for transfer and connection. The insured person holds the "payment voucher" to the social security institution of the new employment place to apply for the continuation of the old-age insurance relationship. 3. The old-age insurance relationship will be handled by the social security agency of the original insured place and the social security agency of the current insured place, so that the insured person's insurance records can be connected.
