The last month deducted double the amount of five insurance and one pension

Are you asking why the last month's deduction was double? The last month's double deduction is because you left your job. In China, if an employee leaves a job, the employer is obliged to settle the employee's salary and pay the relevant social insurance fees to the social insurance department, including pension insurance, medical insurance, unemployment insurance and work injury insurance, as well as housing fund. If the employee has not completed one year's contribution period before leaving the company, the amount of the last month's social security and provident fund contributions will be double, due to the need to settle all outstanding contributions prior to leaving the company, as well as the need to pay the last month's social security and provident fund contributions. Therefore, the double deduction for the last month is due to separation from service.
