Comparison of poetic expression techniques

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".
