1, analogy
Bixing is "or a metaphor, or a form, or a quasi-heart, or a bixing." . There is also a more commonly used technique, that is, "personification": personification with things or personification with people.
2. Exaggeration is to enlarge the things to be described, just like the "capitalization" and "close-up" shots in movies, so as to attract readers' attention and association. Although it is not true, the image he created vividly shows the characteristics of things and expresses the poet's passion, which is not only acceptable to readers, but also convincing and surprising.
3. Metonymy
Is to replace that thing with this thing. Similar to analogy, but different. The difference lies in: analogy is generally compared, and comparison is concrete and visible; Metonymy is concrete on the one hand and abstract on the other, which bridges the gap between concrete and abstract, makes the image of poetry more vivid and prominent, and arouses readers' association.
