Metaphor is not a general thinking activity in images, but an intuitive thinking activity in images that establishes identity relations between distant heterogeneous things. For example, when dusk spreads in the sky, it looks like a patient is anesthetized on the operating table. (TS Eliot). The new critics' understanding of the carrier and theme of metaphor is that it is far from homogeneous in nature, but it has something in common.
As for Bixing, Bixing is on the one hand, that is, "compare this thing with other things", and Xing is on the other hand, "say other things first to arouse the words sung". In terms of prosperity, one is the rise (peacock flying southeast) and the other is the entrustment (Lisao). One more thing, the metaphor of new criticism is a term in the analysis of literary criticism poetry; Bixing is a means of expression in literary creation, and the corresponding literary criticism method is Mencius' theory of "opposing one's will with one's will".
