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.

"I personally feel that there is still a little luck in this, After breaking up the colony, For a few more minutes, I don't know, Because this is the first time I have met such an 'opponent', No one has experience, Anyway, one is counted as one, It is true that there is no end to shooting with guns. Fortunately, there were flamethrowers prepared to counter the impact on the position at that time. The model I remember was 74, At that time, it was still a relatively new model. In terms of performance, The direct firing distance of '74-jet' (abbreviation of 74-type flame thrower) is about 50-75 meters. If the soldiers who operate it are not specially trained, Generally, only straight-line targets can be hit, It's a little bit of a slope, But in the hands of specially trained veterans, '74 Jet' can fire into that air, Although the range is much less than that of direct shooting, Only 25-30 meters, But after all, he didn't take it to the plane, It is used to deal with enemies in low-rise buildings in street battles. Therefore, it is enough, but it is quite dangerous to spray high-altitude targets with flamethrowers. After all, the fuel sprayed out is liquid. Once the distance and wind direction are not grasped well, it is easy to let the fuel sprayed out fall back again. If it accidentally splashes on oneself, it is really a "fire".
