How can the old-age insurance paid in other places return to Tai 'an?

You can go back to Tai 'an, first go to Jinan Social Security to transfer to Tai 'an, and then go to the social security bureau or street office where your household registration is located, and do personal endowment insurance, so you can pay it yourself. Your mother is 50 years old and has not reached retirement age. Women who have reached the age of 50 and are still working in this unit and have paid the old-age insurance 15 years can apply for retirement, except for special jobs. How many years has your mother paid the endowment insurance? I'm afraid I have to wait until I retire at the age of 55. At present, pension insurance is not available in many places. If your company is willing to pay back the money for its employees, you can also pay back the money, but the company has to bear the late payment fee, and this method is not available in all regions. Or you can pay every year. Your mother hasn't retired anyway.
