What does the image of "beauty" mean in ancient poetry?

The king's desire for beauty is a metaphor for his desire for the king. This image first appeared in Qu Yuan's Li Sao: "Only the grass and trees are scattered, and the beauty may wither." Beauty refers to the monarch, who knows how to pity vanilla. In addition, for example, "the swing inside the wall is outside the road, and the beauty inside the wall is laughing outside the wall", comparing yourself to a pedestrian, the king is more beautiful than the beauty, and it is impossible not to cherish the king. Of course, some people compare beauty to a virtuous minister, and compare the king's longing for a virtuous minister to a man's longing for a lover. Different poems are different and need careful analysis.
