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無奇不有，本節目以十個改編故事，將歷年來發生過、流傳過的駭人聽聞詭異事件搬上螢幕，並以佛家哲理帶出善惡因果的警世信息。《上错花轿嫁对郎》是根据台湾纯情女作家席绢的小说《上错花轿嫁对郎》和《请你将就一下》改编的。故事讲述了一个悬念迭起、妙趣横生的古代民间故事。相传在某个朝代的扬州，有两个美丽的姑娘，一个是城北富商的小姐杜冰雁，一个是城东武师的闺女李玉湖，二人同年同月生，又在同一天出嫁。富家小姐杜冰雁要嫁到林州，武师闺女李玉湖要嫁到金州。杜小姐未来的丈夫是柳州巨商齐府的三公子。是相信重要的朋友，还是背叛重要的朋友。该剧讲述了职场萌新记者程了与棋坛风云人物盛景初之间陪伴守护的治愈系甜恋故事，蕴含中华文化丰富内涵的创新题材搭配全新组合CP本片讲述了一起在煤渣胡同长大的铁猴（黄景行 饰）和铁蛇（敖犬 饰）兄弟情深，大哥铁蛇为人仗义有担当，是这帮胡同串子的依靠。铁猴爱街舞胜过爱生命，在小飞（孟美岐 饰）家寄养长大。害羞默默守护一起长大的妹妹小飞多年。
