Can social security be reduced after the 25th?

According to the inquiry of China Travel official website, the maintenance time of social security system is 1 until 5 o'clock every month. You can apply for social security relief from May to the end of the month and pay social security on the 25th. If the social security reduction and exemption is carried out before 25th, it will take effect in the current month, and this month's expenses will not be paid to employees. After the 25th, there will be fewer people. When social security is paid on the 25th of this month, employees still have to pay it.
