One day. According to the inquiry of China Bank official website, how long it takes to unfreeze the bank card automatically after freezing depends on the freezing reason. If it is frozen due to incorrect password input, it will be automatically unfrozen the next day. Because the bank loan or credit card overdraft has not been frozen, it will be unfrozen the next day after all the arrears are repaid. Because of the judicial freeze, the first freeze can last for up to six months, and it can be extended for another three months after six months.
