You can actually log in to CCB Credit Card official website to inquire about the credit card charging standard of CCB. Click on "credit card products" in the upper left corner, and then there is "charging standard" in the lower right corner. The annual fee is differentiated according to the level of the card (

Hong Kong, Macao and Taiwan tourist cards currently only have gold and platinum cards). As for the cash withdrawal fee and interest, all credit cards of CCB are unified.

There are only two situations that will generate interest:

The current credit card bill cannot be fully repaid, so the consumption will bear interest. Every consumption in the bill will be charged from the day of consumption, with a daily charge of five ten thousandths, until you pay off the consumption.

there is overdraft withdrawal in the credit card. Since cash withdrawal does not enjoy interest-free, it will be charged from the day of cash withdrawal, with a daily interest of five thousandths and a handling fee of five thousandths (the lowest 2 yuan and the highest 5 yuan).
