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.故事发生在肉类加工厂。车间工会主席大李，是一个热心于各种社会工作、群众关系极好的先进工作者，不过身体甚差，天阴下雨必然腰酸背痛，绰号叫“气象台”。老李和小李是一对父子，小李有青年人火热的性格，生活给他带来了无比的快乐...万两黄金，不能耽误燕南天片刻，但是一只小燕子却能，无非一个义字而已。时光流转，时间从幕末时代跳跃到现代的日本学园，本剧讲述了千鹤进入首次男女混校的薄樱学园后，作为全校唯一的女生，发生的奇妙的心动青春故事。女匪首林晓月一见钟情戏班弦师木根，准备将其接入山中成亲。面对这样“彪悍”的老婆，木根三番五次想要逃离却被百般刁难，致使笑料百出。有次林晓月让他去砸窑师长吴宗昌，靠岳父起家的吴宗昌正在筹谋找山贼绑架自己的夫人，而这与木根的计划“不谋而合”…….亲事照做，只是我们不必要为其承担任何的义务。　　此剧讲述了像ripley症候群一样，想要过着她人的生活的一个女人安娜的故事。
