The meaning of this sentence is to be a villain first, then a gentleman. Refers to the words that care about the gains and losses of interests first, and then talk about friendship.

Whether it's the allusions left over from ancient times or the common saying that it's better to be a villain before a gentleman, it's up to the other side to make an analysis of the realization of the benefits, so whether it can be achieved depends on their own considerations. It will also provide a reference for the development of the follow-up things. Since the ugliness has been said in the front, the result in the back is at least stronger than that in the front, so that everyone can accept it more easily, and if there is a problem, it is better to solve it.

However, in real life, there are also some problems in the practice of putting the villain first before the gentleman. Some people often misunderstand because of these real opening remarks, which leads to some behaviors that cannot be completed, but because they have a clear conscience, they will not affect their subsequent lives.

On the contrary, if the gentleman comes before the villain, the contrast is very serious. Compared with the heaven and the earth, the dog's tail is full of confidence at the beginning, and the mink continues at the end. This strong contrast is easier to rebel against people's psychology, and the obstacle between the two is also very strong.

So it is the best solution to talk about everything on the table.
