The credit card of CCB has the function of overdraft withdrawal, but it is limited to 2,000 yuan per day, with a handling fee of 0.5% (the lowest in 2 yuan and the highest in 50 yuan) and interest of 0.5% per day.

If 1 000 yuan is withdrawn, the handling fee is 1 000 * 0.5% = 1 000 yuan, and the interest is 1 000 * 0.05% = 1 yuan/day. The interest on withdrawal shall be collected from the date when the withdrawal is recorded in the account until it is fully paid off, and the compound interest shall be calculated monthly.
