In real life, China's income tax is divided into enterprise income tax, foreign-invested enterprises or foreign-invested enterprises income tax and personal income tax. 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.平和、乐观、坚韧的“包子女”孟初夏，因为带着一个十五岁的“儿子”而成为剩女，她与沉稳理智的海归高富帅沈岸因为好友何若男相识，后来进入沈岸的公司工作，二人渐渐产生感情。而张伦硕饰的李泰迪在学生时代就爱慕孟初夏，出国后回国，依然深深爱着她。三人的关系最终将怎样发展?刚认的干娘一边用帕子帮他擦嘴，一边连声道：慢点吃，慢点。Yu Ying's father grabbed tonic for his future son-in-law.
