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.　　本片根据蒔田光治的原作改编。郭家驹（潘粤明）大学毕业后创建了一家小型IT公司，但因经营不善负债累累，被迫将公司关闭后，他也失去了女友。不巧的是，在老家福建某个小山村的父亲此时病重，家人要他立刻带女友回去，情急之下，郭家驹租下“三陪小姐”莉莉（李佳璇），要求对方假扮教师冒充他女友回家交差。和对自己来说绝对是个巨大的优势。In ES6, imports is a read-only view of exports.
