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.Know the principle man: Very good, your experience value has improved a lot. However, we can't start fighting monsters yet. After all, no monster can be directly sprayed to death. You lack tools. Then at this stage, we need to strengthen our programming ability. First find a framework to come down, read the source code, what? You said you can't read the source code, it doesn't matter, there are a lot of experience reading the source code online. Of course, the basis of these experiences is without exception: read more and write more. On this basis, find trick again. After the source code of the framework is set down, change some codes to run, debug them, and then constantly find out the reason to see how each API is written, and try to write it yourself. Write more and practice more. After 30 years of hard coding, you will definitely get something.　大学生村官孙浩然在英杰村创业，在书记田三友等人的支持下，不到两年，英杰村便成为宾县社会主义新农村的典型代表。上级下达并村文件，因涉及英杰村百姓利益，激起百姓不满。孙浩然考察杨家屯，几翻波折后发现温泉，于是一个建设温泉小镇生态旅游专线的构想慢慢形成。招商之路艰难，孙浩然提出一个大胆的想法——动迁。但村民们各怀心思，动迁工作难上加难。当村民们乔迁新居，英杰温泉酒店一期工程奠基之时，资金突然断链，村民们纷纷闹了起来。田三友坐镇村中，孙浩然四处奔走续接资金，终在县委县政府的帮助下，取得借款，资金链得以接续。英杰温泉度酒店建成，喜讯传来：孙浩然当选“最美村官”，赴北京领奖该剧由一对获得艾美奖的编剧（制片人）组合开发，获得艾美奖的Andy Samberg和Andre Braugher主演，故事主要描述一个很有能力但是缺乏责任感的侦探如何向刚刚走马上任的顶头上司证明自己。张大栓似乎觉得丢下小儿子有些不厚道，咳嗽一声，对他道：杨子，你安心做官。一位名叫John C.
