In the historical substitution principle, the methods of the subclass to the parent class should not be overridden or overloaded as far as possible. Because the parent class represents a well-defined structure, subclasses should not destroy it casually by interacting with the outside world through this standardized interface.

HBO的这部暴力，描写监狱生活的剧集是一部令人上瘾，激素窜升的肥皂剧。第一季的8集给整个剧集设定了基调：大量演员塑造的栏杆内外逼真的人物形象，4，5个故事以快速而令人窒息的速度发展，并伴有愤怒而古怪的旁述和戏剧性增长的死亡率。由杀人犯（Homicide）的制片人Tom Fontana创作，这部剧集很快赢得了“最暴力的电视节目”的称号。本片像是简单的化学反应：在一个局限的密封的容器内融合各种爆炸性的元素并用力摇动Oswald劳教所（被犯人亲切的称为OZ）的黄砖路延伸到“Emerald城”--用混凝土和玻璃建造的洁净的狱所，由监狱改造倡导者Tim McManus监管。第一季介绍了两位最引人注目的犯人：律师Beecher，从一个懦弱的羊羔变成一个无畏的吸毒的山猫：还有穆斯林积极分子Kareem Said，一个凶猛的非暴力领袖，其监狱改造运动最终以季末高潮的暴动结束。第一季的演员还有：Ernie Hudson--狱长，Rita Moreno--戒毒修女，Edie Falco--女巡视长官。

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forums have seen beginners ask whether WCF still needs to learn in depth, because they think these technologies may be outdated.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.
