No social security, only provident fund.

The policy of "five insurances and one gold" varies from place to place. Take Shanghai, Beijing, Hangzhou and other cities as examples, the provident fund and social security cannot be paid separately, both of which are items that employers must pay. Housing accumulation fund, like the "five risks", is legally binding. No matter whether the employer and the employee agree to pay the housing provident fund, the employer cannot be exempted from the legal obligation to pay the housing provident fund for the employee in the prescribed way and amount. The unit shall pay the housing provident fund in full and on time, and shall not pay it overdue or underpaid. When the rights and interests of employees' provident fund are infringed, they can go to the provident fund management center to complain and report, instead of bringing labor arbitration to the labor arbitration department.

In addition, the provident fund consists of the monthly contributions of employees and the monthly contributions of employees. These two parts are essentially part of the employee's salary and the housing salary increased by the unit to each employee in the form of housing provident fund, both of which belong to the employee's salary.

Therefore, it is recommended not to do so.
