You can check the repayment date on the website of CITIC Credit Card, which is generally about 22 days. That is to say, if you bill in August 10, then September 2 is the final repayment date, and the most cost-effective thing is to bill on the billing date (for example, 1 1). 12), which takes a long time. You paid 1 1 in August and didn't pay it back until 10/0. Brush 1000 yuan on August 9 and pay it back on September 2. Understand? Never apply for installment ~ ~ It will cost a lot of money ~ ~ Never give the supplementary card to your wife or lover. Once the quarrel is over, but remember! ! ! Brothers are tragedy textbooks.
