Language has non-compulsory customary logic, its phonology, rhythm, the three-character, five-character, seven-character singular text structure unique to ancient poetry and metrical poetry, or the four-character, six-character plural The structure can reflect the special phonological beauty. Chinese poetry has a very important feature. Its rhyme, rhyme and language structure are composed of monosyllables. Wang Wei's "Pastoral Music" is composed entirely of six-character sentences.
Ancient poetry pays attention to using different even and odd numbers of rhymes to interpret the rhythm of the poem.
The lyrics are an adjustment to the neatly arranged metrical poems, but there are also specified word count requirements. This requirement is mainly related to the rhythm of language and music. Through the interpretation of strong musical rhythm, poems are easier to remember and can better exert their appeal.
