Qu Yuan's allegorical technique of "Beauty Vanilla" in Lisao has gone far beyond the so-called "Bi Xing" in The Book of Songs. Bixing in The Book of Songs is often just a fragment of a poem, a simple metaphor and association, but Qu Yuan's works have undergone great changes and development.
First of all, it began to mix and blend things, feelings and scenery with me. This is not simply comparing things with things, or getting excited by touching things, but combining some characteristics of things with people's thoughts, feelings, personalities and ideals, and combining feelings with things through association and imagination to form a symbol, thus greatly enhancing the artistic tension of poetry.
In the long poem Lisao, the poet grasps the rich aesthetic connotation of fragrant flowers and herbs, beautiful trees and Merrill Lynch, and the love between men and women itself to beautify the image and character of the lyric subject.
