The gas coupons given by Bohai Credit Card will be bound to the credit card when refueling. When refueling, you can enjoy discounts by using the account bound to the credit card to pay, or you can also enjoy discounts by paying directly with the credit card. Credit card gas discounts are generally divided into two situations. One is a preferential card, such as a bank car owner's car card, which provides direct gas discounts or gas tax rebates. The credit card in this case can be used directly after refueling, and the fee will be paid directly after discounting, or the fee will be refunded to the bank card within the specified time after swiping the card.
