　　期盼着和平的国家，而成为了土耳基史上最年轻的将军。古人学武，只杀敌不表演。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.Combination function is to encapsulate various algorithms into small functions one by one, for example, if level A is used, encapsulate a small function, if level B is used, encapsulate a small function, and so on; The following code:Auxiliary Class:《好家伙》:“好家伙”，是革命队伍中一群藉藉无名的战士对自己的戏称，因为他们亦戏称敌人为“坏家伙”。一九四零年皖南事变后，这群意志坚定的好家伙们受命掩护一位重要的同志去上海，而他们并不知道这位重要同志是他们中的哪一位。从大西北到大上海，沿途会遇到土匪、国民党、汉奸、日军等等各色坏家伙们的狙杀。而好家伙们这回不仅要用生命、智慧、梦想和死谏去护送自己的同志，而且他们也在保护和挽救国家的希望——抗日统一战线。在护送的途中，坏家伙们从西北荒漠到繁华上海层层拦截，他们在天外山拦截，在黄沙会拦截，在国统区拦截，在日占区拦截，在船帮拦截，在天目山拦截。好家伙们中不断有人牺牲，他们运用各自的智慧，排除各种困难，完成了党组织交给的任务。同时好家伙们用自己的行为教育顽固势力，以民族大义为重，大家一致对抗日本侵略者。
