The Liskov Substitution Principle (LSP) is one of the basic principles of object-oriented design. The Richter substitution principle says that wherever a base class can appear, subclasses can certainly appear. LSP is the cornerstone of inheritance reuse. Only when derivative classes can replace base classes and the functions of software units are not affected can base classes be truly reused, and derivative classes can also add new behaviors to base classes. The Richter substitution principle is a supplement to the "open-close" principle. The key step to realize the "open-close" principle is abstraction. The inheritance relationship between the base class and the subclass is the concrete realization of abstraction, so the Richter substitution principle is the specification of the concrete steps to realize abstraction. --From Baidu

I remember the fighting was fierce, Almost everyone's barrel was red, But that's it, There is still a "slip through the net" in these things, Towards the end of the third exchange of fire, And one came up from the right side of the position, I turned around and shot it, After pulling the trigger, One shot hit him in one of his hind legs, I watched helplessly as the impact of the bullet knocked its hind legs off its body. But it doesn't seem to care, It is still a leap forward, He threw himself on a soldier named Zhou Xiaolin beside me. Biting his thigh and not letting go, Ge Xiaolin's painful "wah-wah" yelling, I think we've just had an attack, A little respite, He asked two people to help him get this thing off his leg with me. As a result, I was busy for nearly 5 minutes, Break this thing up with a dagger, But it did not let go, Finally, I used a faster knife. It's only by opening its mouth from the outside to the inside that it's allowed to let go. But Zhou Xiaolin is still relatively unfortunate, Although the thing was loose, almost a small watermelon area of meat was torn off on his bitten left thigh, and the thigh bone inside could be seen from the front. A cyan artery on the outside of the thigh was also exposed for a while, while he himself was in a coma due to excessive blood loss and severe pain.
