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.　　铁匠铺二徒弟林成锋,在八路军团长崔洪年的影响感召下,走进了革命队伍,而师哥孟德彰则参加了国军,两个人选择的道路不同,却同时爱着师妹韩雅兰。在一系列感情纠葛、爱恨情仇中,最终却与真爱失之交臂。但，这并不是陈启实力不够，而仅仅因为陈启出道的时间太短，缺乏时间的沉淀。
