Loans overdue won't sue the Postal Savings Bank for a month. According to the news of Hua Fu Lawyer Network, failure to repay the bank within 1 month will result in penalty interest. After six months, the bank will file a lawsuit with the court, and the court summons will be sent to the borrower's home. On the day of the court session, regardless of whether the borrower appears in court, the court will freeze the collateral originally mortgaged by the borrower to the bank and then auction it. The proceeds from the collateral auction will be used for repayment.
