Ancient poetry
Ancient poetry is a genre of poetry. Judging from the number of words in poetry, there are four-character poems, five-character poems and seven-character poems. Four words are four words, five words are five words and seven words are seven words. After the Tang dynasty, it was called modern poetry, so it was usually divided into five words and seven words. Five-character ancient poems are referred to as five ancient poems for short. Seven-character ancient poems are referred to as seven ancient poems for short, and those who use three, five and seven characters at the same time are generally considered as seven ancient poems.
Poetry is the sentence that makes up poetry. Poetry usually limits the number of words in each sentence according to its format. China's earliest poems were structured with metrical poems, and the metrical requirements were strict. For example, the poems in the pre-Qin period are generally four-character poems, which can be found in the Book of Songs. Later, it developed into a five-character or seven-character rhythmic poem, which was found in Tang poetry. After the further development of economy and culture in Song and Yuan Dynasties, the content of poetry was gradually expanded and deduced. In the later period of the new-democratic revolution, poetry evolved into a free poem that was not limited by the number of words.
