First, the formation of metrical poems is different from quatrains. Rhyme is generally created directly by poets. Just like aphorisms, after determining the title and theme of the verse, it is equivalent to basically determining the framework of the verse. A poem has five words, and there are seven words in it. Five words are called five-character poems, seven words are called seven-character poems, and two sentences are a couplet. The average poem is four sentences, that is, there are always eight sentences. There are also more than eight sentences, and more than eight sentences are called xenophobia.
Second, the structure of metrical poems. Rhyme is generally divided into four parts, and every two sentences in these four parts should be strictly opposed. Let's give an example. Two orioles sing green willows, and a row of egrets go up to the sky. Two to one line, oriole to egret, singing willow to heaven. Not only that, level tone should also echo Liu and Tian relatively. However, leveling is generally not as strict as sentences. A rhyme is usually used on the rhymes of four letters and eight sentences. It is the end of the second sentence, the fourth sentence, the sixth sentence and the eighth sentence that rhymes with a tone, which is a good metrical poem.
Third, quatrains are relatively simple. A quatrain is simply a truncated sentence of a regular poem, which is a punctuation poem formed by intercepting some essence from a regular poem. The theme of metrical poetry is much simpler than that of metrical poetry, which is generally divided into four parts and four sentences, with five-character quatrains as the most. But quatrains also pay attention to antithesis and rhyme, and the last word of the second sentence and the fourth sentence should rhyme.
