My credit card text message reminds me to pay back on April 3. Do I have to pay interest if I don't change or postpone the repayment?

Hello, if you are a credit card of China Merchants Bank and fail to return the minimum repayment amount of the bill in time before the due repayment date, you will be charged a late fee and interest, and your personal credit will be affected. The overdue fine is 5% of the unpaid minimum amount, and the minimum amount is RMB 10 yuan or USD 1 yuan. Interest refers to the collection of all consumption in the current period from the bookkeeping date (usually the day after consumption), with a daily interest rate of five ten thousandths until you pay it off in full. In order to avoid affecting personal credit, it is recommended that you repay on time. If it is not convenient to pay off the bill in full, please pay off at least the minimum repayment amount on time.
