The second kind of people are narrow-minded, selfish and haggle over every ounce. I know a few such people who only think about themselves and don't care about the interests of others at all. When he takes advantage of you, he is unambiguous at all. As long as you don't explicitly object, he will take as much as you want. But on the other hand, if you take advantage of him, he will hold a grudge against you, and he will have to come back after seizing some opportunities. It is really boring to get along with such people.
The third kind of people are people who are particularly good at' pretending'. Such people are parasites of the company. Don't look at his usual set of principles and principles. He seems to be very capable, but when it comes to serious work, they can't do anything, just pointing fingers at us young people, saying that achievements are their own, and if they make mistakes, they will stay away. For example, in a meeting, you can talk about your work in front of your boss for an afternoon, from history to stories, from truth to chicken soup for the soul. The only thing you don't talk about is how to solve the difficult problems at work.
The fourth kind is people full of negative energy. They are depressed every day. If something goes wrong, they will complain to you endlessly. What's the matter? This work is difficult to do. The heart is not old, you can sigh. Stay with these people for a long time, even if you are positive in the sunshine, you will be infected by them. You only have negative emotions, you can't see anything and you can't work hard.
For the above four kinds of people, you should neither get too close to them, nor have obvious rejection to them, as long as you know what you are doing. After all, China is a human society, so you should learn to deal with all kinds of people.
