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.

Some plants are very picky when choosing pollinators. The flowers of European Trollius are like a real safe deposit box, and only six kinds of insects know the code to open the safe deposit box. These lucky people all come from the genus Brevicorn. Only they know how to get into the sepals of European Trollius and find the center of the flower. However, no matter how hard other insects try, they can only fail with disappointment. The short-horned flower fly, which has gone to great pains to pollinate European Trollius, will naturally receive considerable "remuneration". Female short-horned flower flies lay eggs on the carpels of flowers. When the larvae are hatched, they will eat the seeds of flowers and grow up. This symbiotic relationship also has certain risks for European Trollius. The more short-horned flower flies, the greater the chance of pollination, but at the same time, the more insects parasitic on flowers. The cooperative relationship between the two was formed millions of years ago and continues to this day. It is a model of relative balance and harmonious symbiosis in nature.

"This time we can get that position out of danger, All by one radio station, At that time, we used rifle butts, stones, bayonets and even belts and helmets to fight these rats hand to hand. But I can't, There are too many of them, And you can take care of the earth and not the sky, Either killed by a big mouse or stung by a big wasp, Even some soldiers were anxious and hugged with big rats. And bite it with his teeth, However, this will not change the overall situation at position 149, which is very unfavorable to us. So it didn't last long, Seeing that the position was about to fall, The impression is that a person in our company, Should be a company correspondent, He sent the message directly to the back on the radio. Request the artillery to cover position 149, To live or die with the position in the way of "firing at me", Because I was very close to him, So I could hear what he was shouting, I thought I wanted to die bravely, But in the end, Through the superior order he conveyed, The response we got was to evacuate us to a hillside due north of position 149 in 3 minutes. This means that we have to give up the defense of the main position for the time being. To be honest, He had already killed the red eye, No one wants to withdraw, Watching his comrade-in-arms get along with him day and night be stung to death by a big wasp, I was killed by a big mouse, and I was always left with a dead body. All of them were bent on killing one more one to avenge their comrades. I remember very clearly that I saw with my own eyes that at least three comrades had been bitten off their arms and necks by that big mouse. One of them had his stomach bitten through and his intestines flowed all over the floor, but they were still fighting.

OCP (Open-Closed Principle) principle emphasizes that a software entity (class, function, module, etc.) should be open to extension and closed to modification. That is, every time there is a change, the behavior of the existing type should be enhanced by adding new code instead of modifying the original code.
