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.民国初年，滇国一带流传着一种神奇诡异的“神农药谱”，谁占有它，谁就能成为无可非议的“帮主”。当时显赫一时的“神农帮”三位帮主为了夺此药谱展开了一场骇人听闻的“火拼”。三个帮主的子女为报父仇，各自结帮营私寻找药谱而结下新的恩恩怨怨，江湖人互相猜疑，酿成了一起又一起的腥风血雨和相互暗杀的悲剧…　　敬文不知所措，但舅舅却施展法术，证明自己的确去过另一个时空。敬文决定将舅舅接回公寓同住，一方面是没有其他亲戚肯帮忙，一方式是他觉得可以利用舅舅的能力来赚钱。杜小姐见她想不出，便道：这个或许不是你们小青山来的。Experimental process:道：红椒妹妹，你听我说。杂货店主人冯寒梅正被匪兵调戏，遇李宏成营长带兵前来搭救。一波未平一波又起。这时，粮仓被烧，火光冲天逼人，李营长领人冲进火海，奋力救粮，冯寒梅将店里的新桶全部献出装水，引得众人称赞，灭火后，二班战士在瀑布下洗澡，突遭土匪袭击，班长壮烈牺牲，神秘的电波不时出现。刚解放的万山县城又处于动荡的变幻中。
