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.《命运与愤怒》以想改变自己命运的具海拉(李珉廷饰)和与她命运般相恋的仁俊(朱相昱饰)为中心，讲述交织着命运般的爱情和凄切的愤怒的四位男女的故事。是现实性的强烈的传统浪漫电视剧。尹旭下意识地握了一下拳头，抬起脚步台上鼻阶，一步步走上台阶的高层。够了。Shutter speed is also called slow shutter.
