The base of the provident fund does not match the salary.

Legal analysis: there is a difference in the social security base, so you can report it to the social security audit department of the county where the social security unit is located and ask the enterprise to make up the difference. Housing provident fund must be paid in proportion to the actual salary, but the average monthly salary of employees in the above years is the standard. The company pays social security for employees, and employees need to pay it for employees after they join the company, so the company pays it first, and then deducts personal contributions from their wages.
