If Chongqing participates in the basic medical insurance for urban workers as an individual, the social security agency will entrust the bank (Yuzhong District is the Postal Savings Bank) to deduct money from the personal deposit account at the end of each month, and the deduction period is about 20-30 days. The insured person can check the transaction details (print the passbook) at the bank regularly, or check whether the deduction is successful through the banking service telephone.
