As seen above, we directly call that subclass baiDuInterview.init () method. Since our subclass baiDuInterview has no init method, but it inherit the parent class, we will look for the corresponding init method in the parent class. Therefore, it will face the prototype chain and look up in the parent class. The same is true for other subclasses, such as Ali class code, which will not be introduced much here. For the parent class, this method Interview.prototype.init () is a template method, because it encapsulates the algorithm framework in the subclass. As a template for an algorithm, it guides the subclass to execute the code in what order.　　此剧采用一剧上下两部的形式，上半部剧的主题是＇贝塔项目＇，讲述2017年外星人题材的奇幻悬疑故事。两旁各立着三个军汉，手握钢刀，一副要斩人的模样。大业末年，战乱四起，晋阳留守李渊次子李世民于郊外狩猎时，射落的乌鸦落在了一顶华丽马车前。李世民“一箭贯穿咽喉”的手法吸引了车中的女子，使她顿生仰慕之情，但口中却讽刺他骄傲自大，年少气盛，世民丝毫不恼，反而戏言会娶她为第二个老婆，车中女子大怒离去，但临别之际，却忍不住掀起车帘回眸望去，这一望恰巧与世民惊羡的目光交接在一起，她禁不住娇然一笑，妩媚无限，世民见到她娇好面容，一时间竟呆在当地，再也移不开目光......One problem with the factory method pattern is that the creation of the class depends on the factory class, that is to say, if you want to expand the program, you must modify the factory class, which violates the closure principle. Therefore, from the design point of view, there are certain problems, how to solve them? We use the abstract factory mode to create multiple factory classes, so that once new functions need to be added, we can directly add new factory classes without modifying the previous code. Because the abstract factory is not very easy to understand, let's look at the diagram first, and then it is easier to understand with the code.该剧根据汪一洋小说《洋嫁》改编，讲述了一位跨国追爱的北京大妞，在海外经历辛酸打拼、爱情浮沉后最终选择回国成就梦想与幸福的暖心故事。《桐柏英雄》是一部中国解放战争题材的电视剧，改编自同名小说《桐柏英雄》。由桑华、祝东宁、白杨导演，何晟铭、张逗逗、金晨等主演。
