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.黎水慌忙帮大哥澄清道：周姑娘请放心，我哥哥没说要娶南雀公主，都是将士们不肯吃亏，为了壮声势，才故意那么喊的。Because the scenic spot has tropical rain forest ecology such as "bangen", "strangulation", "parasitism" and "stem flower", it is called "Xishuangbanna in southern Fujian" by tourists.
