This is an immortal poem. At the beginning of the poem, review your life. It is intended to imply that no matter what difficulties and hardships, you are tempered and fearless. Then I described my combat career: I spent four years in a desolate cold war environment. Linking personal destiny with the rise and fall of the country. Three or four sentences continue to express the development of the situation and the deep sadness and anger from both the country and the individual. This couplet is neat and the metaphor is appropriate, which truly reflects the social reality and the poet's experience at that time. The national disaster, personal bumpy experience and all kinds of pains tormented the poet's feelings, which made his words doubly sad. Five or six lamentations are deeper, once again showing the poet's painful inner trembling because of the collapse of the country and his distress with typical events in his encounter. The last two sentences converge the whole article with great momentum, and write a heroic oath that would rather die than surrender, meaning that since ancient times, has there been an immortal body in life? As long as we can make this patriotic loyalty shine in the history books. This famous saying, which has been told through the ages, is a hymn of an ideal life written by the poet with his own blood and life. The whole poem is gloomy and tragic in style, and it is a great patriotic poem that touches the world and makes the gods cry.
