It should be noted that banks generally give credit lines after comprehensively evaluating customers' repayment ability according to their income level, occupation, assets and liabilities and the credit status of other banks. Maintain good consumption habits for daily consumption in shopping malls, supermarkets, gas stations, restaurants, tourism, entertainment and so on. Swipe more cards and use active cards for a long time, so that banks can understand the cardholder's quota demand, repay on time and maintain a good credit record, which will help cardholders improve their quota.
