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孝明世子李英（朴宝剑饰）是朝鲜第23代国王纯祖的长子，个性必须请。收到神秘短信的志浩得知诗雅是吸血鬼，但因为相信与诗雅之间的真爱，志浩并没有因为种族的阻隔而选择放手。这时诗雅的家人却出现阻止他们相恋，诗雅几经周折终于知道原因，原来她是高阶吸血鬼，会对人类造成伤害，越是爱志浩，越会不受控制的吸收志浩的能量。为了保护志浩，诗雅拒绝了志浩的求婚，两人分手。志浩看出诗雅有心事隐瞒，下定决心搞清楚事情的真相，志浩的编辑崔俊赫鼓励志浩，不论遇到什么困难都不要放弃与恋人一起的决心。志浩决定，这次换他来主动追求幸福。与此同时，辛巴却发现有神秘的力量一直在盯着诗雅，因为怀疑与诗雅身份有关，表面上与诗雅决裂的辛巴，实际上却在调查针对诗雅的势力。志浩发现崔俊赫接近自己的目的并不单纯，于是与辛巴里应外合，终于让崔俊赫露出马脚，暴露出崔俊赫的终极目的，其实是为了获得诗雅的全部能力来复活因他而死的爱人，崔俊赫与诗雅一样是高阶吸血鬼。虽然崔俊赫的阴谋被阻止，但志浩也为了救诗雅而死，诗雅决定牺牲自己救活志浩，接着陷入了昏迷中。三年后，诗雅醒来竟然变成了人类，与志浩再没有任何阻隔，大家俞大猷苦中作乐笑道，曹巡抚亲上前线，苏州补给又跟得上，咱们当兵的岂有打败仗的道理？不得不说，狼兵的确骁勇。Squat down, grab bars, lift, shoulder support, bow legs, clean and jerk... on the afternoon of the 8th, when the peninsula reporter came to the weightlifting training hall of the city sports school, the afternoon training class had already begun, and more than 20 female athletes were silently repeating their exercises and lifting barbells again and again. Different from the traditional impression of reporters, weightlifters are short and stout. Some of the girls here are over 1.70 meters tall. Most of them are well-proportioned, with beautiful hips and tight arms. Only a few of them are tall and stout, while the rest can't see any trace of stout. "Because China used to do weightlifting at small levels, people saw the success of 48kg and 52kg athletes, so they took it for granted that weightlifting would make people grow short, but in fact scientific practice would not affect children's height development. Just imagine, even in daily life, how tall can a person weightlifting about 100kg be? Plus muscular will appear stout, but this does not mean that all weightlifters are stout. Five or six little girls in our team are over 1.70 meters tall, and some boys are nearly 1.90 meters tall. " Liu Eryong, coach of the women's weightlifting team, told reporters that weightlifting not only did not affect the height of the children, but also did not destroy their figure. "As you can see, because of the long-term squat practice, the children's thighs and buttocks are very beautiful. Some small fat people have lost more than 10 kg in a few months and their muscle lines look better. With the deepening of scientific training, weightlifting is no longer the sport that people think destroys their bodies.
