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.Peter Boyd探长指挥着一支经过多种训练的警探和科学家的警察队伍-悬案小组，使用现代的方法和原来调查时还没有的新科技来专门调查的未破获的老谋杀案。跟孤魂野鬼般游荡了一个多时辰，正要退回去，忽听二门外有人说话。《深宅》是以深宅老院——乔园地下的宝藏为引线，讲述一段带有悲剧色彩的爱情、亲情故事，其中，“琼女郎”秦岚和“武侠皇后”郑佩佩在剧中上演了一对深爱儿子的母亲，虽然都为人母，但两人性格却大相径庭，白玉兰个性固执，对儿子却百般顺从；乔母视财如命，因觊觎王府的财富而强行把儿子乔日升和有孕在身的白玉兰拆散，做法虽过份，但也是想在自己死后为儿子留下一笔财产。该剧由来自《迷失》的制片人组合J.J.
