Is Cao Zhi's seven-step poem harmonious?

Ha ha. His poems are very classic. At that time, during the Three Kingdoms period, he mainly followed the> style, and at the same time played the rhyme of Yuefu, which was not strict with the number of words and rhythm of poetry. Although Cao Shi and his son are very particular about literature, it is not easy to write a poem in seven steps. How can we balance rhyming? It should be an ancient poem with word equivalence.
