Liu Xie said in the book Wen Xin Diao Long: Metaphor is "either a sound metaphor, a figurative metaphor, a mental metaphor or a metaphor." There are many examples in the poems we listed before. There is also a more commonly used technique, that is, "personification": personification with things or personification with people. The former is like Xu Zhimo's Farewell to Cambridge: I left gently/just as I came gently; /I waved gently,/saying goodbye to the clouds in the western sky. /the golden willow by the river,/the bride in the sunset; /Beautiful shadows in the waves,/rippling in my heart. Treat "clouds" and "golden willows" as people. People imitate things, for example, Love's Because of the Wind: ... My heart/as bright as the candlelight in your window/slightly ambiguous/inevitable/because of the wind/... with the love of my life/light a lamp/I am a fire/may go out at any time/because of the wind. Compare "my heart" to candlelight, and compare me to a lamp. Of course, in the final analysis, the essence is "personification".
exaggerate
It is to enlarge the things to be described, just like the "capitalization" and "close-up" shots in the movie, to attract readers' attention and association. Li Bai's Peach Blossom Pond is deeper than thousands of feet, so it is not as good as Wang Lun (for Wang Lun), "Flying down three thousands of feet, suspecting that the Milky Way will fall for nine days" (Looking at Lushan Waterfall), in which "deep thousands of feet" and "three thousands of feet" are mentioned, 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. However, this exaggeration must be artistic and aesthetic, not too absurd, not too real, and not too vulgar. Limerick is a special form of street literature. For example, there is a jingle describing the bumper harvest of cotton: "A cotton bag/truck head stuck/stuck, three feet high/like an anti-aircraft gun." After reading it, people feel unreal and can't feel good.
Metonymy and other rhetorical devices
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.
