You beat six and I beat six. The oriole and the lark can't finish singing. What is rhetoric?

Personification is a rhetorical device, which endows non-human things or abstract concepts with human characteristics and behaviors and makes them more vivid. The oriole and lark in the sentence "You clap six, I clap six, and the oriole and lark can't sing" are endowed with human behavior, that is, they keep singing and vividly express their constant singing. This rhetorical device makes the description more vivid and interesting, and enhances the appeal and vividness of expression.
