It depends on what kind of person the other person is. Although it is difficult to judge, you can also try to explain the benefits of credit cards to him according to your age. Young people should advocate online shopping for free and fast payment, and explain that they can accumulate points to get rewards! It depends, but be sure to smile and hand in your work certificate as soon as possible, otherwise others will think you are a liar and may not be used to it at first! I wish you success.
