Swearing is actually lowering your own quality. First of all, swearing is uncivilized. And swearing shows that you are incompetent and have no solution to the problem. Some people, if you scold him, he will get angry, which shows that his endurance is not enough, but some people have no influence on him because they scold him without substantial harm. If the other party scolds him, it shows that the other party is angry, and he has the upper hand, so why argue with him? So it is unwise to call names.
