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 nodded at this passage, Understand that what Zhang Xiaobo said is indeed reasonable, It is not a lie, Here I think it is necessary to give you one thing about popular science. So we have to say something digressive: The result of a real bullet hitting a petrol tank is not the same as that shown in most movies. One shot can explode the petrol tank, But this is not the case, Although a pure metal projectile will rub against the air at a speed of hundreds of meters per second to generate equivalent heat, And will produce sparks after hitting the metal oil drum, But none of this is enough to ignite petrol, Especially for gasoline with a large total amount, to ignite gasoline, please remember one thing-open flame must be used. In addition, gasoline is a flammable item, but it is not an explosive item in the true sense. Only after reaching a certain total amount can explosion be caused. If the total amount is insufficient, it can only cause combustion without explosion.

香港七十年代初期，当时还没有成立廉政公署，贪污情况泛滥成灾，民不聊生。警局沙展王一冲（狄龙 饰）为人正直不阿，不肯同流合污，因此而不容于其他同僚，在警局受到排挤。在一次行动中，王一冲的手下莫森（任达华 饰）甚至从背后开枪将他打成重伤。与此同时，港督麦理浩委派百里渠爵士调查香港的贪污情况，其助手马安妮找王一冲帮忙。经过调查，王一冲了解到莫森击伤自己也是出于无奈，莫森其实为势所逼，于是找到了莫森并在警校中挑选了一批精英学员，共同开始搜集贪污集团证据，打响香港廉政第一击
