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 BaiduBetween flowers and insects「鹿枫堂日和」讲述的是和风咖啡馆·鹿枫堂内上演的各种日常故事。店主スイ(东极京水)负责店内的茶水冲泡、ぐれ负责店内的咖啡制作、椿负责店里的甜品制作、ときたか负责店内的料理制作，四个青年共同组成了这个鹿枫堂，同时店内也经常迎来一些有着烦恼的客人，故事围绕着鹿枫堂的经营者和客人们开始展开。豹子头林冲是一个家喻户晓悲情式的英雄，他始终坚持自己的原则即使充满了复仇的怒火也不滥用暴力。他对生活由充满信心到迷茫到再次坚定，在磨炼的过程中他通过亲身的经历和自己的思考来提升自己。他在磨炼中变得逐渐坚强起来，他试图通过自己的奋斗来改变命运。然而他虽然做出一系列的努力但最终还是被奸人所害，他的愿想也就落空了，他的行为也让人感到遗憾和惋惜。本故事避开古装片一贯人物脸谱化的窠臼，通过对一个个人物心理层面的把控和社会层面的分析,达到推动故事发展和深化主题的目的，呈现给观众的是一个有所触动并能引发一定思考的故事上周他买了五本《武侠世界》被顾小玉嘲笑很久，但是后来付宇锋想清楚了，多买两本怎么能算是浪费，他有那么多同学，那么多朋友，就算是买上十本，也不会浪费，所以这次他就买了十本。
