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故事讲述二十世纪初满清灭亡后军阀割据的动荡时局下，龙奇从一个力求独善其身的平凡小人物在恶势力压迫下奋起反抗的励志故事。廊檐下也都挂上了红灯笼，院中红光烂漫，那雪片在朦朦光晕中飞舞，宛如飞花飘落，更镀上一层旖旎色彩。此剧讲述不再梦想罗曼史的大叔和大妈的真实爱情故事，描写担心会孤独死的独居男和担心独居的孤独女的生存生计爱情。在阿桑·迪奥普十几岁的时候，他的父亲因含冤入狱而离开人世，此后他的生活发生了翻天覆地的变化。25年后，阿桑受到“怪盗绅士亚森·罗宾”的启发，决心为父报仇。这短笛是板栗从元国弄来的，草原上人召唤鹰用的。
