If you are a shopaholic, I suggest you apply for CITIC's Magic Card. If you spend this card a lot every month, there will often be double points or over-value purchases. Considering that you are an office worker, you are usually very busy. From the point of view of convenient life, I suggest that you set up a credit card for the payroll bank, associate the payroll card with the credit card, and handle online banking business, so that it is convenient for you to overdraw and repay, avoiding the two situations of saving money in order to pay back the credit card, or paying for transfer and repayment online, and you can shop, pay fees and invest online.
