Will Shanghai Social Security expire next month? Such as March to February.

Most social security contributions are paid every other month, which is related to the payday. Most units pay wages after going to work, because the first month's salary can be used as the base of individual payment to calculate the payment amount.

Therefore, the social security in April was paid in May, and the list printed by the social security agency is the most correct. Online information can be used for reference, but it cannot be used as evidence.
