For children, the movie "The Battle of Changjin Lake" can intuitively let children see the scene of the war between the two countries, and even very young children can feel the ethnic differences and different positions between the two countries, which can help children understand the concept of the country initially. For older children, we can further deepen our understanding of the country by thinking about some issues, such as: why there is a war between countries, what are the differences between the two sides' positions, how far away the war is from our own country, why the volunteers can defeat the better-equipped American troops, and so on. I believe that this is also the germination of feelings about home and country and the beginning of patriotic thought. Life is precious, and only faith has a value beyond the body! We often lament that today's children are fragile, unable to bear hardships, lack respect for life, and lack toughness and willpower. Then, how can we influence children's outlook on life and values bit by bit, so that children can cherish what they have now while enjoying a good life and know that today's happy life is hard to come by? The shocking scenes, tough environment and tenacious will in the battle of Changjin Lake can certainly shock and enlighten children. When Lei Gong died in the movie, it can be said that the audience fell into a state of collective tears, and many parents also said that their children were very sad to see it here. In this situation, men, women and children all feel the same emotional resonance and fall into the same sad moment. This is also one of the few places in the film that depicts the pain of the physical body carefully and emphatically. It can be said that it is the crowning touch of the film and a classic scene that touches people's hearts.
