What rhetorical devices did Wang He use in the first two sentences of Rain Clear? What kind of feelings does it show the author?
The first two sentences use contrastive rhetoric. It is a contrast between two different aspects of the same object in contrastive rhetoric, that is, flowers before rain and flowers after rain. The contrast between two different scenes expresses the author's infinite regret that the flower buds did not open before the rain and fell after the rain, and he could not enjoy the flowers all the time.
