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.我脑子又没毛病，跟你赌这个。《深夜的士》讲述在深夜的北京街头，有一辆的士，营业时间由深夜零时到早上的 7 时左右。司机是个 30 岁出头的男人，他外表冷峻，内心却像天使一般温存。他和每一个夜间的乘客，进行心灵上的交流，并带出一个充满人情味的故事。刚刚大学毕业的安可，在求职过程中屡屡碰壁，正在焦头烂额时候，解释了网络八卦主播糖果。安可在糖果劝说下，开始了网络主播行业，却因为刚入行不了解直播行业，屡屡闹出笑话。
