在军中，得罪同袍的事最好少干。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.讲述了一名落魄球员不放弃心中的足球梦，在一次偶然的机会下组建球队，参加杀手联盟举办的特殊“世界杯”。面对其他队伍的阴谋诡计，中国队全力以赴并请来了神秘外援，最后赢得比赛，完成了自己的“足球梦”。快和我细说一下。　　是一部在绝望的瞬间，重新站起来的人们重置人生的治愈电视剧。讲述了外柔内刚的恢单女和身无分文的单身父亲相遇后，治愈彼此伤痛的“互愈罗曼史”。First look at the local image and select one as the base image:So the result is?
