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.Advantages and Disadvantages of 2 Events一之濑步（中岛裕翔 饰）从小就将成为杰出职业围棋手作为毕生的理想，无奈高中时代家中突遭变故，父亲去世，生活的全部重担落到了母亲（朝加真由美 饰）孱弱的肩上。坚强的母亲全力的支持着步实现他的理想，步亦凭借着努力和智慧在成为职业棋手的道路上艰难前行，可是最终，已经23岁的步还是失去了成为职业选手的最后机会。
