You are the wind and I am the sand adopts the expression technique of "bi" in the Book of Songs.
The expression techniques of "The Book of Songs" include: Fu, Bi and Xing.
1. Fu is a direct description, that is, the poet expresses his thoughts, feelings and related things in a straightforward manner, and directly describes a certain thing from multiple angles. For example: Li Chunbo's song "Xiao Fang" "There is a girl named Xiao Fang in the village. She is good-looking and kind-hearted, with a pair of beautiful big eyes and thick and long braids."
2. Comparison is an example. To compare something to this thing, to compare is to make an analogy. For example, the theme song of the TV series "Huan Zhu Ge Ge" is "You are the wind and I am the sand lingering around the world."
3. Xing is to use other things to elicit the meaning of this thing, which is equivalent to a symbolic rhetoric method. The word "Xing" originally means "rising", so it is often called "rising". "Xing" in "The Book of Songs", according to Zhu Xi's explanation, means "preface other things to trigger the words to be chanted." It is often used at the beginning of a poem or chapter. Sometimes when a sentence in a poem seems to be Xing, you can judge whether it is Xing by whether it is used at the beginning of a sentence or paragraph.
Extended information:
The use of Fu, Bi and Xing is not only an important symbol of the artistic characteristics of The Book of Songs, but also opened up the basic techniques of ancient Chinese poetry creation. The three techniques of Fu, Bi, and Xing are often used interchangeably in poetry creation, and together they create the artistic image of the poem and express the poet's emotions.
