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.《读心探案》是一部刑侦社会剧，讲述新一代公安刑警，运用犯罪心理分析和网络时代新科技，刻画作案动机，侦破离奇疑难案件的故事，堪称一部当代犯罪心理侦破实录。该剧改编自同名人气网漫，讲述失忆的超能力刑警“东柏”遇到连续杀人事件后发生的故事。 由电影《邻居》《石雕宅邸杀人案》的金辉导演、《恩珠的房间》苏在贤导演共同执导，2020年播出。百无聊奈，看着春光再一次从身边滑过，少女有些着急了。1943年，特种兵部队奉命深入敌后摧毁日寇大规模杀伤性武器，却遭日寇设计而全军覆没，队长尤龙的遗孀周至柔的小妹周志卿，奉国民党军统高层命令查清此事。调查过程中，周志卿身陷险境，正巧被我地下党人赵凯所救，自此一见钟情。两人通力合作，经历重重险境。周至柔是国民党特种部队“猛龙”大队大队长的妻子，中共高级特工，在“猛龙”大队被日本间谍告密而全军覆没后，她同时执行查处奸细并摧毁日寇的任务。当他们终于查出了真相，并摧毁了日寇的大规模杀伤性武器时，更为严峻的考验接踵而至，日寇的惊天阴谋渐渐浮出水面，而最危险的日谍“枭”仍然潜伏在他们身边……
