If you don't use a credit card, the bill shows 160 yuan, which may be the annual fee generated by the card. I suggest you look at the bill details and have a detailed explanation, or you can call the bank directly to ask about the specific situation.

There is an annual fee for credit cards. Gold and ordinary cards can be exempted from annual fees as long as they are swiped in the bank. Most platinum cards charge a fixed annual fee. Your credit card should be closed in time, not stored. The annual fee has been collected, depending on your situation. You should pay off the annual fee quickly, or you will charge interest later and report it to the central bank's credit information system.
