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).个性天真率直的龙女（袁洁莹 饰）尝试到人间学习施雨的方法，而她必须化身为人。她本想在繁华的人间到处游玩，却深深吸引住了乐善好施的叶希（陈浩民 饰），两人展开了一段“人龙爱恋”。但“人龙相恋，必遭天遣”，导致状况百出，一发不可收拾，但他们还是热爱着对方。另一方面，与叶希一起长大的周处（钱嘉乐 饰）虽然武功高强，但性格刚烈。他一度认为龙是万恶之源，立志要以屠龙为己任。一次正当他上山屠龙之际，竟被他误救出了美丽的新月公主（张燊悦 饰），不久便展开了一段若即若离的感情。没想到的是新月公主竟然也喜欢上了叶希，一段四角关系应该如何解决？ABC喜剧《喜新不厌旧 Black-Ish》在五月前获预订座落在Freeform的衍生剧，现改名为《成长不容易 grown-ish》（前名《college-ish》），首季为13集，预定在明年1月3日播出。《成长不容易》讲述Zoey在离开家人来到大学后，很快发现这里的生活不能事事如意。母剧演员Deon Cole会在衍生剧继续饰演Charlie，他在大学兼职当市场学教授。Emily Arlook饰演南加州大学新生Miriam，「万事通」的她对人十分坦率，该角在母剧中原本由Mallory Sparks饰演。Chris Parnell饰演南加州大学的事务主任﹑Trevor Jackson饰演一个具有社会意识的大二学生，他们已在后门试映集出场。The turn signal must be turned on when the vehicle changes positions, and the only one that cannot be turned on is to enter the roundabout (turntable).《老来难》，语言通俗，描述细腻，道尽老年人的生活特点和万般苦痛，劝人要孝敬老人，尊重老人，并委婉告诉人们，人人都要经过老年这一阶段，孝敬老人也是尊重自己。过去，有人用这首《老来难》写出一个老人拄杖的画像，形象逼真，农村人贴在屋里，用来提醒人们的孝敬心，久传不衰。　　开朗、自信的女人。世界上有很多不如美人长得好看的女人，但是她们同样可以遇到帅哥。如此说来，杨长帆治天下，是比子升要高明了。
