Fu Bi's prosperity is the three main expressive techniques in The Book of Songs, and it is an induction of the expressive techniques of China's ancient poems. Fu: Direct narration, laying out details and parallelism are equivalent to the rhetorical methods of parallelism now. Bi: Metaphor is equivalent to the rhetorical method of metaphor now. Xing: Holding something up, saying something else first, and then associating it, leads to what the poet wants to express, thoughts and feelings, which is equivalent to the current symbolic rhetoric.
Fu Shuo's truth is that people express their thoughts and feelings and related things in a straightforward way.
For example, comparison is the most basic technology and the most common technology.
Xing, say something else first and let the lyrics be sung.
