How do you deal with people who blurt out curse words?

I think those who blurt out dirty words are signs that they have not restrained their behavior. When they were very young, it may be because others used such words to influence them, and then they also used this kind of words to influence them. He gradually formed such a habit in order to retaliate against others. It is also because over time, he has no way to change. So I think this kind of person just has no way to self-discipline and no way to correct himself. Behavioral habits, many times his habits are bad, and generally this kind of person is a person with relatively low quality and relatively low education.
