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.来人问了平安，就告辞了，说张家人才到京，诸事忙乱，不敢打扰，等他们歇息两天、安定下来后，再亲来看望。电视剧由王杏元和程贤章合作完成的小说《胭脂河》改编，以抗日战争后期为历史背景，以平远县城仁居镇为事件发生地，以三位风尘女子的爱情故事为主线，反映了当时纷繁复杂的战乱生活，地处大后方的山城也危机四伏，也必然给人们带来思想观念和行为方式的种种变化。
