As long as there are 3 thousand yuan, all three credit cards can be returned.
First, you have to adjust the repayment amount of your bill. It's all set at 3 thousand yuan. Then the next month, you can spend both cards.
The method is as follows,
Ping An's bill is overdrawn by 3000 yuan. 1, change to a safe one. Then the third accounting day is 3000.
On the 9th, Ping An 3000 was brushed out and returned to China Merchants Bank. Then by 12, the bill amount is still 3000.
2 1 date, brush out the 3000 from China Merchants and return it to CCB. Then by the 25th, the bill will still be 3000.
When the number is 1, switch to Ping An by swiping the bank. The bill number 3 is still 3000.
In this way, the bank's 15000 yuan will remain in your hand, and how long you want to use it depends on yourself. You can contact me if you don't understand.
