It is normal for bank staff to promote the products of their own units. The key is whether we are willing to do it or not. Whether there is a need to use a credit card, whether the salesman can get a commission or whether there are indicators on it, I think if he is a leader, he will definitely let his employees market his products. That's understandable. But we can't be forced to apply for a credit card, and if we really want to do it, we should have a general understanding of what the credit card is and how to use it before using it, otherwise it will be bad for the bank to deduct fees or affect personal credit records. But now that credit cards are very popular, young people basically know what's going on. I'm used to it. I think credit cards are good.
