Not a Guangzhou hukou, I bought social security after working in Guangzhou. How to enjoy social security benefits after retirement?

I don't think it can only be collected from different places.

Non-registered employees in cities and towns reach the statutory retirement age, and go through the formalities of enjoying the basic old-age insurance benefits like employees in township enterprises in this city, that is, apply in writing, bring their ID cards, household registration books and personal account manuals of basic old-age insurance in Guangzhou to the social insurance agencies in time to go through the formalities of enjoying the basic old-age insurance benefits, and bring their ID cards to the social insurance agencies for review every July. To reach the statutory retirement age in different places, the required documents and materials (my written application, Guangzhou personal account manual of basic old-age insurance, a copy of my ID card and a copy of the household registration book) should be sent back to the social insurance agency in this city to go through the formalities of enjoying the basic old-age insurance benefits, and the social insurance agency in this city should handle the payment of basic old-age insurance in different places according to my requirements. Audit procedures are required in July every year (the personnel issued in different places provide the survival certificate issued by the household registration police station every year).
