This is when you go to the CCB counter to handle online banking, and one of them is the upper limit of each payment, which depends on your personal decision (sometimes the bank service staff will ask you how much to set, and I will ask me when I go to handle it, and I will set the upper limit at 1000, as if the maximum limit can be set at 2W). According to what you said above, when you apply, just limit the ceiling to 500, if it exceeds 500.
