The ancients said, "Every man is responsible for the rise and fall of the world." I didn't understand this sentence very well before, but it was just a literal feeling. I don't know much about national defense and think it's too far away from me. That's a matter for the country and the government, I don't have to worry about it. Now, the Chinese nation has experienced the Opium War, the Sino-Japanese War, the Northern Expedition, Eight-Nation Alliance's invasion of China and the brutal Nanjing Massacre ... National defense education is urgent!

So, what is national defense? National defense refers to the country's efforts to guard against and resist aggression and stop armed subversion. Terrorists and so on. Defend the sovereignty and unity of the country. Simply put, it is national defense. Why do you want to carry out national defense education? The answer is simple: strengthening national defense education is to carry forward the spirit of patriotism, enhance citizens' sense of urgency, and let that humiliating history be remembered in everyone's heart.

The third Saturday in September every year is National Defense Education Day, which is a wake-up call to the past in the present peaceful times. As the saying goes, "He who has no long-term worries will have near worries." How can we forget the painful history of being bullied? Eight-Nation Alliance invaded China because the Qing government was corrupt and incompetent? Otherwise, how could China lose 654.38 billion taels of silver, thus making China's economic lifeline in the hands of imperialist powers? Yuanmingyuan was looted and many cultural relics were scattered overseas. What a painful lesson!

We are the protectors and builders of the future of our motherland. Ten years later, we will all take up the post of building and defending the motherland and shoulder the heavy responsibility of defending the motherland. Primary school is a critical period for a person to lay a good foundation. In order to contribute to the motherland, we must receive national defense education. On the basis of learning scientific knowledge well, we should train our various skills to lay a good foundation for building and defending the motherland in the future.

Some people say, "The hero who defends the territory against foreign enemies is the Great Wall of Wan Li." And I want to say: "We have something stronger than the Great Wall of Wan Li, and that is the firm patriotic belief of China people!" Now, as a primary school student, I have such a dream that when I grow up, I will wear a green military uniform to defend the frontier of the motherland. Although this dream may not come true, my patriotism is sincere and passionate.

Students, as a new generation of students, we should inherit the glorious traditions of countless revolutionary ancestors, build China into a civilized modern military power with firm steps, and let the splendid five-star red flag stand in the east of the world forever! Let's build a solid Great Wall of National Defense, realize the Chinese dream and build a beautiful home!
