I have resigned, and the company's social security has been deducted from my personal salary.

Legal analysis: employees who leave their jobs and work for less than one month in the current month need to pay social security for them. Moreover, individuals and units need to pay social security fees in accordance with the provisions of national documents, and there can be no illegal deduction in violation of the Social Insurance Law.

Legal basis: Article 9 of the Interim Provisions on Wage Payment. If both parties to the labor relationship dissolve or terminate the labor contract according to law, the employing unit shall pay the employee's salary in one lump sum when dissolving or terminating the labor contract.
