Parallel prose is a style of writing in which words and sentences are opposed to each other to form a piece. Four or six sentences are commonly used, and most of them are even sentences.
Rhyme is very rhythmic, and most even use words with the same rhymes as the end of sentences to create a rhyming style or article. The number of rhyme words may be long or short.
Poems are generally short in length, and Cao Cao's poems do not pay attention to rhyme.
