Liskov Substitution Principle, LSP (Richter Substitution Principle) means that subclasses must replace their parent types. In other words, in the process of software development, after the subclass replaces the parent class, the behavior of the program is the same. Only when the subclass replaces the parent class and the function of the software is not affected can the parent class be truly reused, and the subclass can also add new behaviors to the parent class. In order to look at an example of violation of LSP principles, the specific code is as follows:郭家驹（潘粤明）大学毕业后创建了一家小型IT公司，但因经营不善负债累累，被迫将公司关闭后，他也失去了女友。不巧的是，在老家福建某个小山村的父亲此时病重，家人要他立刻带女友回去，情急之下，郭家驹租下“三陪小姐”莉莉（李佳璇），要求对方假扮教师冒充他女友回家交差。　　齐宣（明道 饰）是当红模特，英俊帅气，有着一大批忠实的女粉丝。曾经，一场意外让齐宣和钟无艳相识，彼此定下了婚约，如今，齐宣已然成为了一个标准的“颜控”，面对“丑陋”的钟无艳，他避之而不及，与此同时，一位名叫夏迎春（王思平 饰）的美艳模特出现在了齐宣的身边，把他迷得五迷三道的，这让深爱齐宣的钟无艳深感心痛。齐宣不需要钟无艳的感情，却需要她的智慧，他需要钟无艳帮助他坐稳集团总经理的位置。影坛鬼才王晶早期一部具国际视野的动作电影，全片除了充满越战式的游击战斗，还有传统的埋身肉抟，并在泰国实地取景。巨富之女贺盈聘请罗力于七天之内到柬埔寨，从杀手乃文手上夺回一盒录有商业秘密之录音带。罗力为了一百万酬劳，毅然与贺盈订定合约，并召集好友组织一支敢死队，潜入柬埔寨与游击队交涉。几经艰险，罗力终于完成任务，不料整个事件背后原来有极大阴谋……　　阴森狰狞的老管家雨果（杰克·梅伊 Jack May 配音）无时无刻不在设法让达寇拉重新变成吸血鬼，而身形巨大的天然呆女佣南妮（布瑞恩·楚门 Brian Trueman 配音）又总是无意中破坏着一切。加上可以在规定时间内瞬间前往世界各地的城堡。达寇拉展开了一次次惊险刺激、快乐有趣的大冒险…The reporter interviewed in depth and detail, In-depth interviews were conducted with several current and former middle-level and senior officials of the securities and communication company.
