Others make mistakes, which may be right, that is, condescending psychology, which is easy to forgive.

If others make mistakes, prove that they are also wrong. At most, everyone is wrong. Everyone is half a catty and easy to forgive.

If others are right and they hold different views, they are probably wrong. Two things are hard to forgive: first, not admitting that you are wrong; Second, it is hard to accept that others are better than themselves.
