In a sense, the soul of poetry is actually emotion, that is, all scenery words are emotional words. That is, poetry expresses ambition, poetry is considerable, exciting, collective and resentful. You should understand what you are writing and what you are writing for. However, in modern poetry, poetry is full of diversity, but it is only about emotion, meaning, rhythm and so on. Combined with this work you posted, it's hard to say what the soul of poetry is. But it is definitely not imagination. Imagination is only the distance that poetry can reach, but it is really not the soul. As for me, I can only try nonsense here
Keep waiting.
