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.就听一阵脚步响，进来四五个少女，皆是锦衣绣服、珠玉耀目、富贵之极，好容易恢复镇定的白果顿时又张大了嘴巴。“如果我是你合适人选，那么从现在开始，你不能对我说不。”从朋友到爱人。当一个是好人，而另一个是坏男孩时，这种关系会如何发展？有没有可能把坏男孩变成恋人？SYN Gateway:这是一部充满眼泪与凄情、坚韧与奋斗的故事，是一部感天动地的历史长卷的关于命运苍凉而又令人振奋的书写，是一部弥漫着中国古老而又生机勃勃的传统美德的力作。全片自始至终蕴积着情感与道德的力量。On May 3, 2018, U.S. Treasury Secretary Menuchin, Trade Representative Leticize, Chief Economic Adviser Kudla and Trade Adviser Navarro, Commerce Secretary Rose and Deputy Adviser on International Economic Affairs Essenstadt, and U.S. Ambassador to China Branstad arrived in Beijing to hold talks with China on economic and trade issues.
