The meaning of vanilla
The image of vanilla has two meanings, one is the nobility of morality and personality. Poets sometimes call themselves vanilla, and sometimes they refer to people they respect, all of whom are noble people. Second, it is opposite to evil grass, symbolizing both sides of political struggle.
The implication of beauty
The image of beauty is generally interpreted as metaphor, or king, or self metaphor. Among them, the most concentrated expression is the metaphor of the relationship between men and women. The former is like "only the grass and trees are scattered, and the beauty is afraid of dying." The latter is like "many women are jealous of Yu's eyebrows, and they say Yu is good at prostitution." It is not only vivid, but also in line with China people's thinking habits to describe the change of the relationship between monarch and minister with the change of men and women's engagement.
