The meter of classical poetry is relatively free, informal and even. The rhyme foot is wide, except for the rhyme foot of seven-character white and bright sentences, which generally rhymes with other sentences. The rhyme foot can be flat, flat or variable. The length is not limited, and the sentences are generally neat, which can be divided into four-character poems, five-character poems, six-character poems, seven-character poems and miscellaneous poems. Miscellaneous poems are mainly composed of five words and seven sentences, which are generally divided into five ancient poems and seven ancient poems.
Meng Haoran's Spring Dawn is an ancient poem!
