Haha, the credit limit of Bank of Communications cards is generally very strange. It is best to cancel the account of the card that is not used. Although it is now stipulated that no annual fee will be charged if you do not open a card, some banks still do not implement it.

Credit card limits vary from person to person, and each bank has its own set of review system rules. Maybe you have a platinum card at this store, but maybe they won't approve your card at that store.

Swipe your card slowly and the limit will go up. Generally, after opening a Bank of Communications card, you have to swipe the annual fee-free card, which seems to be 6 times, and then stop swiping it. After half a year or a year, your credit limit may be increased to encourage you to use the card. Stimulate your consumption. I have an account and all my friends are like this
