China Construction Bank's credit card is stipulated in this way. First of all, there is an accounting day, and this is the dividing line (I don't remember excluding the day). Consumption before this date will be refunded within 20 days after the bill date. Consumption after this date will be refunded within 20 days of the next billing date.

This is very vague. For example, my bill date is 10.

So if I spend or withdraw 10 yuan on June 9 and June 1 1 respectively.

Then I must return the first fee 100 yuan and the second fee 100 yuan before1October 30th.

In other words, the credit card money of CCB can generally be used for at least 20 days. This may take up to 50 days, depending on the time from the date of your bill.
