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.众人吓了一跳，尤其是小葱，慌忙对板栗使个眼色，微微侧头，向后面那对主仆瞟了一眼，一边道：三叔这是什么话？宁静郡主家世容貌品性，无一不是上上的，三叔又没定过亲，怎么不行了？板栗也急忙道：就是。This method requires the salesman to directly target the customer's main purchasing motivation, directly sell to him, beat him off guard, and then "take advantage of the situation" to persuade him in detail.

When the master opened the door, the man asked, "Is there a high-grade food mixer in the house? "The man was shocked. This sudden question left the host at a loss as to how to answer. He turned to discuss with his wife, who was a little embarrassed but curious and replied, "We have a food mixer in our house, but it is not particularly advanced. "The salesman replied," I have a senior one here. "He said, and took out a high-grade food blender from his bag. Then, it goes without saying that the couple accepted his promotion. If the salesman changes his way of speaking, he will say, "I am a salesman of X Company. I came to ask if you are willing to buy a new food mixer. "Do you think about the marketing effect of this kind of talk?如果按照之前韩信所策划的关中谋略，只要指挥实施得当，这成功是必然的。为了挽救最后的幸存女孩，一位潜心于一项突破性研究计划的儿童临床医学家凯瑟琳·迪恩，受命用现代高科技进入到昏迷杀手的大脑当中。她进入杀人凶手的灵魂无疑是一次奇异未知并且充满危险的旅程，当她进入后，一个FBI探员紧随其后，同时间赛跑去揭开层层线索，查找那个失踪女孩的下落。不幸的是，事情并没有像预期那样的顺利，凯瑟琳·迪恩发现她被困在了这个杀手的思维世界里，真正有欲罢不能的感觉。周芷若被黄衫女子制住，动弹不得。燃烧的腐魂
