Imitation of poetry: First of all, we should pay attention to imitating the format of that poem. Poetry is very symmetrical, word by word, paragraph by paragraph. That's all that matters.
If ancient poetry rhymes, modern times don't pay attention to these. So, as long as the sentence reads smoothly.
Master the language well and divide the paragraphs well.
That's all. Imitating poetry depends on your understanding of that poem.
