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.本剧讲述了上世纪二三十年代云南腾冲这个翡翠古城的一个传奇故事，一块玉石界天下无双的皇帝玉，一批为它献出生命的玉雕大师，一段经历了岁月洗礼的沉淀，造就了让人垂涎的绝世珍宝，玉中之王，翡翠凤凰！一代玉雕大师文之光因为收藏了 “翡翠凤凰”，招来杀身之祸，各方势力争夺不休，文之光最终导致家破人亡。Join the Doctor, as he teams up with an investigative journalist, and a superhero to save New York from a deadly alien threat.距离1950年国庆节前一个半月的一个夜晚，我军驻北平201情报处收到了一份来自打入国民党情报机关的卧底“中华一号”的机密情报，一个针对新中国首都的“天字一号”战略计划已经悄悄拉开了帷幕。随即，敌我双方同时发现了在各自的内部都埋藏着对方的谍报人员。摆在我方情报高层领导面前的形势极为严峻。当死里逃生的仲华被敌方情报高层指挥者陶然以督办的身份派回北平的时候，敌情非但没明朗，反而更加扑朔迷离。一个又一个潜伏的敌特在被抓之前就相继死去。种种迹象表明，敌方的计划在陶然的尽心策划和指挥下一刻都没停止地深入展开着。面对自己的暴露，仲华坚持要求继续冒险留在敌人的狼窝内与敌周旋，利用督办的特殊身份，他不但要查清敌人的卧底是谁，而且一定要摸到“天字一号”计划行动的细节。于是，一场针对敌方“将计就计”阴谋的“反将计就计”战术被确定了。百姓得知是为怀王报仇，必定全力以赴，上下一心，同仇敌忾。
