For example, your credit line is 10000 yuan, of which 5000 yuan is the withdrawal line. Before the withdrawal (and the total consumption is less than 5,000 yuan), the withdrawal amount remains unchanged at 5,000 yuan. If you withdraw cash, the cash withdrawal amount will immediately decrease with your withdrawal amount. For example, if you take away 2000 yuan, the withdrawal amount will be reduced to 3000 yuan. When you pay off the withdrawal amount, handling fee and interest, the withdrawal amount will be restored to 5000 yuan.
