The principle of opening and closing means opening to expansion and closing to modification. When the program needs to be expanded, the original code cannot be modified, but the original code should be expanded to achieve a hot plug effect. Therefore, a summary of one sentence is: in order to make the program scalable, easy to maintain and upgrade. To achieve this effect, we need to use interfaces and abstract classes, etc. We will mention this point in the later specific design.

……彭城，西楚国都城。
There is a male friend around him who likes a girl very much. They have been good friends for many years. He has considered for a long time and also thought about the consequences of the confession. But in the end, the boy still confessed. Although rejected, he is still a friend. The girl's idea is that being a friend will never be lost. She believes that only friends can last a lifetime. In fact, the boy also struggled for a while. He didn't know what kind of attitude he should use to face the girl after being rejected. I was also worried that their relationship would be far less than before. As both of them were optimistic and cheerful and had a deep friendship, they were still as good as before. Emotionally, boys and girls may have very different ideas. If the girl's confession is rejected, she may not continue to be friends unless the girl is open-minded enough. I remember that I supported this friend's confession very much at the beginning and wanted to help match it up for a time. From the perspective of boys, it is not easy for a person to meet a person he really likes all his life. If he does not try to stay, he will definitely feel sorry in the future. From the perspective of girls, how lucky it is to meet a person who is so kind to himself. But emotional things can never be forced.
