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
一部以新中国第一支刑侦大队在云南成立并屡破奇案为背景的30集电视剧 。该剧以云南首任公安厅副厅长、党组成员曹显政为原型，采取纪实手法，通过扑朔迷离的案件侦破和对不同矛盾冲突中人物性格的深入刻画，再现中国第一代刑侦工作者、云南“神探”曹显政带领云南公安连续三年创造刑侦破案率99.9%的传奇故事。男主人公曹政，从一个部队“误”入公安的“大外行”，成为一个个大案、疑案的“克星”，他既有“不放过一个真凶，不冤枉一个好人”的责任担当和职业本领，也有不拘一格用人才的胆识和气魄；无论什么样的疑难迷案，只要曹政出马，通过对案情“蚕丝剥茧”般的表象排除，最终总能抓住要害，水落石出，表现了广大公安干警“全心全意为人民服务”的共产党人风采，再现了新中国第一代刑侦工作者的英雄事迹和光辉形象。
"'let the dog bite '? Is the" dog "you said a real dog or something else that behaves like a dog?" I have some experience in hearing this, He interrupted and asked again in a "sure" tone. The reason for this is that in the interview at position 169, Qi Shicheng mentioned that the Vietnamese army's humanoid monster in tattered military uniform was like a dog when running, so when I heard Liu Guangyuan also talking about "dog", I was not sure whether the "dog" he said was a "living biological weapon" with Qi Shicheng.

PS: Many forums have seen beginners ask whether WCF still needs to learn in depth, because they think these technologies may be outdated. Maybe Microsoft will launch a new SOA implementation scheme at that time. Wouldn't it be a waste of time to learn in depth, so they feel that there is no need to learn in depth and just know how to use them. I had the same feeling about this problem before, but now I think that although WCF technology may be replaced, the key to understanding a technology in depth is not to know some more advanced API calls, but to understand its implementation mechanism and way of thinking. Even if the latter technology is replaced, the mechanism behind it is definitely similar. Therefore, if you have a thorough understanding of a technology, you will feel familiar with the new technology and relaxed about it. In addition, after you have a thorough understanding of a technology, you dare to say that you have mastered the technology well during the interview, instead of saying that you use it a lot at ordinary times. Once you ask deeply, you do not know the implementation principle behind it. This is also why I want to write WCF series. I hope this opinion is helpful to some beginners.
