At this time, the appearance mode can be used to decouple the client from each subsystem. Appearance mode refers to providing a consistent facade for a group of interfaces in the subsystem. It provides a high-level interface that makes the subsystem easier to use. For example, the customer specialist of Telecom can let the customer specialist complete the services such as charging telephone charges and modifying packages without interacting with various subsystems by himself. The specific class structure diagram is as follows:This is the learning method adopted by most people at present, and it is basically the same as nine.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.1949年夏秋之交，新中国的开国大典即将举行，在刚刚解放不久的边防重镇—丹城，国民党特务活动猖獗，妄图在我立足未稳，内忧外患之际颠覆新生的红色政权。侦察英雄徐程冬刚从前线凯旋，便奉命来到丹城市公安局，全面负责特务清查工作。师长贺群山的女儿贺芝圆暗恋着徐程冬，贺群山的老战友—即将担任丹城市市长的高平也觉得二人是天生一对。不料，刚刚进入丹城，车队即遭匪徒伏击，公安局长贺群山牺牲，临终前将女儿贺芝圆托付给徐程冬。徐程冬内心非常矛盾，因为早在上海担任地下联络员的时候，他与假扮夫妻的葛茵红已经产生了爱情。只是由于革命工作需要，两人天各一方，失去了音讯。为了不辜负师长的临终嘱托，为了照顾孤苦伶仃的芝圆，徐程冬终于答应了这门亲事。他全情投入侦察工作之中，暂时忘却了内心情感的折磨。谁知造化弄人，就在徐程冬和贺芝圆准备完婚之际，徐程冬昔日的恋人葛茵红竟意外出现，并再次成为他的战友，协助他开展特务秘密自首工作。天真的芝圆完全蒙在鼓里，她成天沉浸在即将成为新娘的幸福中，完全不知道徐程冬和葛茵红内心的酸楚。准是看错了。　　在西北野战军总司令员和总政委的战略思想指挥下，西北狼数次扭转战局，配合大部队站稳脚跟。在反攻中，超限、反常规作战更是 尖刀 一般数次插向敌军最薄弱的痛处，“扶眉”“壶梯山”“龙门渡”“荔北”处处留下了他们智慧与智慧的博弈。最终在华山粉碎了对手最后的阴谋，而这群性格饱满、血肉长城般的军人，也在这里了却了最后的爱恨情仇……
