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.　　当失散的小妹忽然有了音信，佳琳选择直面现实，不惜代价争取家人团聚。财阀张墨白的出现为她提供了一条捷径，而站在人生的十字路口，却发现前方有更大的秘密向她招手。为了探究家族没落的原因，佳琳不惜委身张墨白，凭借过人的智慧与努力争取到张墨白的信任，在香港飞速发展的十年，协助他扩展势力，平步青云。　　巫山连日传来努达海兵败的消息，新月实在难以控制自己对努达海的爱和思念，她毅然远赴巫山找努达海，与他共生死。努达海欲为兵败而自刎之际，他听到新月的呼唤，他们再次的相遇，真有彷如隔世之感。那夜，新月将自己的一切奉献给努达海。翌日，他们欲自刎以谢天下，但最后却决定回京面对众人。雁姬、骥远和珞琳实在难以接受新月要成There are many places to recharge Manaka.
