If you have a credit card of Guangfa Bank and want to shop in installments, the installment amount must be less than 80% of the current bill amount before you can pay in installments.
All banks, including Guangfa Bank, have restrictions on the installment amount of credit card holders' bills, but the prescribed proportion will be different. Guangfa Bank stipulates that the installment amount shall not exceed 80% of the current bill (consumption). In fact, this limit is limited by the cardholder's permanent limit (not exceeding). For example, if you are a cardholder, your credit line of Guangfa Bank is 8,000 yuan, your monthly consumption is 6,000 yuan, and your installment amount is 4,800 yuan. I believe you can understand it by analogy with a card friend.
