Can't I buy social security in different places over 40 years old?

People over the age of 40 have the opportunity to buy social security in different places and must meet some conditions. For women, the pension relationship established in different places for the first time after reaching the age of 40 is only a temporary account, so they can't go through retirement formalities in the non-household registration area, and they have to go back to the household registration area to handle retirement matters in the future.
