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

The two sides started an artillery battle over this, Although it is said that our artillery is not only in terms of performance but also in terms of quantity, Both of them had an overwhelming advantage, coupled with the precise positioning of the comrades of the reconnaissance troops, so it took 20 minutes to complete the complete elimination of the Vietnamese artillery group. Later, I also saw in a military magazine that when the artillery battle was the most intense, some artillery comrades who pulled the bolt swollen their arms. It is conceivable how fierce the fight was. " Li Haixin said.
