People recruited by credit card centers rarely stay indoors to do office work, such as auditing and customer service. Most people need to make their own achievements, that is, have you ever seen a table set in front of major supermarkets or banks to provide credit card consultation (sometimes on the street)? That is the so-called stagnation point. These things are done by individuals. Who doesn't need a credit card or two these days? The key is how do you let others handle it in your hands?
