In real life, China's income tax is divided into enterprise income tax, foreign-invested enterprises or foreign-invested enterprises income tax and personal income tax. For these three types of income tax, each is calculated in a different way. Personal income tax has a personal income tax calculation method, while enterprise income tax has its corresponding calculation method. If we do not adopt the policy mode to realize such a requirement, we will define an income tax class, which has an attribute to identify the type of income tax and a CalculateTax () method to calculate the tax. In this method, we need to judge the tax type and calculate the income tax for different tax types through if-else statements. Such an implementation can indeed solve this scenario, but such a design is not conducive to expansion. If the system needs to add an income tax in the later period, it has to go back and modify the CalculateTax method to add an additional judgment statement, which clearly violates the principle of "open-closed". At this time, we can consider using the strategic mode to solve this problem. Since the tax method is the changing part of this scenario, we can naturally think of abstracting the tax method at this time, which is also the essence of the implementation of the strategic mode.Inspector's name, inspection date, inspection category (referring to daily inspection, monthly inspection, quarterly inspection, annual inspection, etc.), inspection content (referring to the content specified in relevant technical specifications of various fire fighting facilities) and treatment results, maintenance date and content.1932年，执行秘密任务的地下党员秦西岳返回家乡照金，让以为他已经牺牲的恋人周谷雨欣喜若狂。秦西岳奔赴甘南执行任务，周谷雨带着秦西岳的弟弟虎儿偷偷尾随。秦西岳潜入警卫团劝说团长带领队伍起义，却发现团长正是自己的大哥秦灿明。在周谷雨和虎儿的配合下，秦西岳计划用自己和周谷雨的假婚礼做掩护，发动兵变。关键时刻大哥秦灿明，导致兵变失败，秦西岳只得逃亡，虎儿则跟随大哥如愿成了一名军人。从此秦家三兄弟分道扬镳：秦西岳是坚定的共产党员，大哥秦灿明是进步的国民党，弟弟虎儿则走向了彻底的反动。回到照金的秦西岳在周谷雨的配合下，建立根据地，他们面对的敌人正是两个亲兄弟。几十年间，秦家三兄弟在亲情和大义中有挣扎，有坚守，有痛苦，有欢乐，也有悔恨，如同那段历史的缩影一般Position 246 Attack% 132%影片讲述了特勤陈子默在执行任务的时候发现自己的恋人邓潇潇的身份十分可疑，就在他要调查清楚此事的时候意外频发，恋人的意外死亡，朋友的出卖，同事的怀疑让他身陷囹圄。陈子默并不知道，所有的意外都是为了他的特殊身份而编制的一个大网。陈子默背负各种压力成为了一位孤胆英雄只身对抗幕后的黑手。海瑞淡然道：行贿也是重罪。
