1. The metaphor is novel and vivid. Tiangou originally existed only in folklore, but the poet praised it as an idol. The image of Tiangou in the poem has become a symbol of rebels in the old times, traditions and the old world, as well as a symbol of personality liberation with unlimited energy and the creator of the new world, society and future. The use of this metaphor not only vividly shows the poet's strong desire to publicize his personality and pursue liberation, but also gives people a refreshing feeling in poetic images. In addition, the poet compared "I" to "X-ray light" and "flying like electricity", which also reflected the characteristics of advocating science at that time.
2. Imagination is bold and strange. The image of Tiangou is vague in legend, but it is transformed into an image of "I" with unlimited energy and fully liberated personality in poetry. He swallowed the moon for a while, the sun for a while, and all the planets for a while, becoming the light at the end of the month, the light at the end of the sun, and the light at the end of all the planets, and then flying, screaming, burning, flying on the nerves, spinal cord and brain, all of which showed the boldness and strangeness of the poet's imagination.
3. Emotion is unrestrained and intense. The whole poem is written in the tone of "I", and the poet uses the dog as a metaphor to express his inner pride through the extraordinary trend of the dog devouring the universe. Poetry runs through strong feelings from beginning to end and has a strong subjective color.
4. Pay attention to the rhythm and sense of rhythm. This poem is also very distinctive in language form. Poets often use short sentence mode, and combine overlapping sentences and parallelism, which produces strong melody, rapid and powerful rhythm and destructive momentum. In addition, the language of the poem is free and the rhyme is rough, which shows that the poet attaches importance to the sense of rhythm.
