Can Shenzhen and Guangzhou buy social security at the same time in 22 years?

Honey, you can't buy it at the same time. Workers who can pay at the same time can pay social security in both places at the same time, but in the end there is only one pension. At the same time, if there are two or more basic old-age insurance relationships, when handling the transfer of the basic old-age insurance relationship, the social insurance agency will negotiate with me to determine to keep one of the basic old-age insurance relationships and personal accounts, and other relationships will be cleared at the same time, and the amount stored in personal accounts will be returned to me, and the corresponding individual payment period will not be counted repeatedly.
