The withdrawal limit of CCB credit card is half of the credit card limit. If the credit card limit of the landlord is 9000, the withdrawal amount is 50% of the credit limit, which means that the cumulative withdrawal amount of this card cannot exceed 4500 yuan.

In addition, remind the landlord that in addition to the cash withdrawal fee (0.5% of the cash withdrawal amount, at least 2 yuan), interest of 0.5% of the cash withdrawal amount will be charged every day, and the maximum overdraft for each card is 2,000 yuan per day.

For example, the landlord withdraws 2000 yuan from the ATM of CCB and pays it back after 10.

Total amount payable = withdrawal principal+withdrawal handling fee+withdrawal interest.

= 2000+2000 * 0.5%+2000 * 0.05% *10 (10 interest)

=2000+ 10+ 10

=2020 yuan

As short as 10 days, the extra cost of 20 yuan will be generated, which is actually quite high. It is suggested that the landlord try not to overdraw cash, or pay it back as soon as possible after withdrawing it.
