No matter what happens, we must work hard ourselves, improve our character, and make progress, without being too affected by the external environment.
Some people do indeed behave poorly, but we should not compare our worst behaviors with theirs, even less should we be influenced by them.
They not only live very poorly themselves, but they often drag others down into the water with them, causing others to live poorly as well.
Pay them no mind.
If we feel angry at them and act out negatively, we'll become very much like them, and life will get harder and harder.
The best course of action is to be more patient, engage in more positive thinking, do more practical work and avoid arguments.
So what should we do if such people target us?
As long as we manage to remain unaffected by them, they will eventually settle down after a while, and then we'll be free from trouble.
If we are influenced by them and behave poorly, many more bothersome issues will follow.
