According to Gui Guzi's skill of recognizing people, if a person has the following four characteristics, then he must never be intimate. The first characteristic is that he has no opinion of his own, flatters his superiors and flatters them. The second characteristic is that you look down on others. The third characteristic is only for oneself, very selfish. The fourth characteristic is unwilling to change and very stubborn.

First, people in modern society are becoming more and more impetuous, and many people are becoming more and more tactful in their work. Everyone knows not to be the first bird, which is very easy to get hurt, so they won't express their ideas easily. However, they are very flattering to others, and they often become have it both ways, and they don't have their own opinions. If they make friends with such people, they will encounter difficulties, not only will they not lend a helping hand, but they will hit people when they are down.

Second, there are some people who are always conceited and look down on others, always think they are the best, and don't allow others to be better than themselves. Once others have a little talent, they will be hit by them, so don't make friends with them. In today's society, many people are saying that everyone will die for himself, but people still need dedication. As long as they can lend a helping hand without harming their own interests, they should help others as much as possible, and there will always be some people who just watch coldly and never care about themselves. Such people should not be intimate.

Third, everyone has his own ideas, but there are also many ideas in the society. What we need to do is to find some that are helpful to us, and then constantly enrich and improve ourselves. However, some people are very stubborn, never listen to other people's criticisms, and refuse external voices. They live in their own world and think about themselves and be themselves, and they will never change. If you make friends with them, your kind reminder will make them.
