Can the social security base be reduced?

Legal analysis: social security can't reduce the payment base, because the payment base of the unit involved in the social security bureau must match the salary of the staff.

Legal basis: Article 16 of the Regulations on the Administration of Housing Provident Fund in People's Republic of China (PRC) stipulates that the monthly contribution of employee housing provident fund is the average monthly salary of the employee in the previous year multiplied by the contribution ratio of employee housing provident fund. The monthly deposit amount of housing provident fund paid by the unit for employees is the average monthly salary of employees in the previous year multiplied by the proportion of housing provident fund paid by the unit.
