What does it mean to maintain the social security center?

When the social security inquiry software inquires about social security information, the page displays "Social Security Center is under maintenance", indicating that the system may be under maintenance/upgrade, and the inquiry can be continued after 24 hours. It is recommended to check the payment information after one day.

If you are in a hurry, you can also call 12333, and then check the payment manually, or go to the local social security service hall to run the query. But it's best to check on weekdays, because weekends are generally closed to the public.
