Rhyme is a form of China's ancient poetry, which usually consists of eight sentences, each with five or seven words. Rhyme of metrical poems is very strict, and a series of rules and techniques need to be followed. The following introduces the basic methods and skills of rhyming rhyme.

1. Requirements for rhyming words. Rhyme words of metrical poems must use the same rhyming words, and cannot be mixed. In metrical poetry, the flat rhyme is generally used, that is, the flat rhyme must be used for rhyming feet. If you use rhymes, you must use rhymes with the same rhyme.

2. The position of rhyme. The rhyming position of a metrical poem is generally on even sentences, that is, the second, fourth, sixth and eighth sentences. The first sentence can also rhyme, but it is rare.

3. The rhyming format. The rhyming format of rhythmic poems is generally "135 regardless, 246 distinct". That is to say, in even-numbered sentences, the rhyming characters can be in the second, fourth and sixth positions, but the characters in the first, third and fifth positions can be flat and even, which is more flexible. However, the words in the second, fourth and sixth positions must strictly follow the principle of alternating flat and oblique tones, that is, flat or oblique tones cannot be used together.

4. Rhyme. Rhyme of rhythmic poetry requires strict compliance with the rules of rhyme, and different rhymes will affect the rhythm and aesthetic feeling of poetry. In metrical poems, two rhymes, namely, the level rhyme and the new rhyme, are generally used. In the ancient sound system, it is divided into four tones, in which the flat tone is divided into yin ping and yang ping, and the three tones are all muffled.

5. rhyming skills. There are many rhyming techniques of rhythmic poetry, such as overlapping words and antithesis, to increase the sense of rhythm and beauty of poetry. For example, the words "Dongli" and "Nanshan" in "Picking chrysanthemums under the east fence and seeing Nanshan leisurely" are antithetical techniques, and the sense of rhythm between the two sentences is also very strong.

The related knowledge of rhythmic poetry is as follows:

1. On the carrier of poetry, it belongs to the category of modern poetry. The origin of the name "metrical poem" is that it is written according to a certain metrical form, and requires specific antithesis and phonology for even sentences (such as couplets and necklaces) of each poem.

2. Structurally, metrical poems are usually divided into four parts, namely, the first couplet, the parallel couplet, the neck couplet and the tail couplet. These four elements all have specific antithesis and meaning requirements. The first couplet usually introduces the theme or the poet himself, the parallel couplet usually describes the scenery or things, the neck couplet usually expresses the poet's feelings or thoughts, and the tail couplet usually summarizes the whole poem or leaves a aftertaste.

3. In phonology, metrical poetry requires that the last word of two or four adjacent sentences be the same or similar, so that the poem can produce a harmonious musical effect when read aloud. At the same time, the requirements for the level tones of rhythmic poetry are also very strict. Through the alternation and opposition of level tones, a beautiful sense of rhythm and cadence of musical beauty can be formed.

4. In terms of expression, regular poems often use symbols, metaphors, exaggerations and antithesis to express themes and emotions. The use of these techniques makes the expression of rhythmic poetry more rich, vivid and implicit.
