How to calculate the pension from Shanghai Social Security to Jiangsu?

Dear, 1. See where the basic old-age insurance relationship is, that is, where social security is paid before retirement. If the basic old-age insurance relationship is in the place where the household registration is located, then the pension will be collected in the place where the household registration is located. 2. The basic old-age insurance relationship is not located in the household registration. If the basic old-age insurance relationship has been paid for 10 years, the pension will be received there. 3. If the basic old-age insurance relationship is not in the place where the household registration is located, and the basic old-age insurance relationship has not been paid for 10 years, it is necessary to return to the last area where the payment has been paid for 10 years. 4. The basic pension relationship is not in the place where the household registration is located, and the payment period of each insured place is less than 10 years. You should return to the place where the household registration is located to receive the pension.
