B) Design principles. Many people have listed seven principles, such as single duty principle, opening and closing principle, Richter substitution principle, dependence inversion principle, interface isolation principle, composite reuse principle and Dimit principle. LSP, I elevated it to one of the three cornerstones of the object-oriented paradigm; Single responsibility and interface isolation are mainly used as the principle of responsibility division in object-oriented analysis/OOA, which you can not pay much attention to at this time. Relying on the inversion principle, I throw it away as garbage, because the opening and closing principle or directly "relying on abstract type principle" already contains the essence of relying on the inversion principle, while the dross of relying on the inversion principle is inherited by IoC. Of course, the pullback, I emphasize very much. Therefore, you need to master the abstract dependency principle (OCP), one-way dependency principle (including the learning of callbacks) and the minimum dependency principle (composite reuse principle, Dimit rule).

《外来媳妇本地郎》是广东广播电视台拍摄的以粤语为主要语言的一部情景喜剧，描述了广州老城区一个有着四个儿子的大家庭，娶了天南海北的四个外地媳妇，由于生活习惯和文化背景的差异，产生了一系列的喜剧故事。这些喜剧故事无一例外都来自于生活，有着鲜活的时代特色，因此，外来媳妇本地郎又可谓是一部紧贴生活、反映时代现状的情景喜剧。在剧中，三代同堂的大家庭不但适合于表现各年龄层次的故事，同时，由于人物关系的多线条设置，围绕着康家一批核心人物，又延伸出更多的次主要人物，从街坊、到外省乃至外国的亲朋、到广州的新移民、闯荡广州的外地人，无所不包，无所不能包。外剧正是有了这样的延宕性和扩展性，才使得它的故事丰富多彩，使人倍感亲切。
