Personally, I will talk about the difference between poetry and painting:
The essence of poetry is lyricism, while painting imitates scenes. No one can deny the lyricism of poetry at all times and in all countries. Plato, who claimed to expel the poet from "Utopia", did not deny the essence of poetry. What he denies is the value and significance of the poet's lyric activities. I can't explain the essence of painting clearly. Talking too much is probably nonsense. Keep it first)
They all have entertainment functions and are virtual spaces. It is estimated that the painting should also pay attention to the problem of shape. Everyone pays attention to "artistic conception", but poetry is easier to convey feelings.
My personal understanding of the phrase "there is a picture in the poem, and there is a poem in the picture" is that the picture in the poem is the reference of emotion, and the poem in the picture is the subsequent extension.
Contact: It is a process of observing, feeling, brewing, expressing and reproducing life.
Well, I admit I can't answer all your questions. It's too big.
