Poetry, pronunciation: shρjù 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 words per sentence, 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.
The sentence, language, image, form and connotation of poetry also refer to poetry.
