What's the difference between poetry and articles?

Classical poetry has no fixed verse and style. All ancient poems are classified according to the number of words in the poem. Four-character ancient poems are referred to as four-character ancient poems for short; Five-character ancient poems are referred to as five-character ancient poems for short; Seven-character ancient poems are referred to as seven-character ancient poems for short. Four-character poems were adopted by people as early as the Book of Songs. But it gradually declined in the Tang Dynasty, and few people wrote it. Therefore, ancient poetry is still expressed in five words and seven words.

Classical Chinese is the written language in ancient China, mainly including the written language based on the spoken language in the pre-Qin period. During the Spring and Autumn Period and the Warring States Period, no articles were invented to record characters, but bamboo slips, silks and other things were used to record characters, and silks were expensive, bamboo slips were huge and the number of words recorded was limited. In order to record more things on a roll of bamboo slips, unimportant words must be deleted. Later, when "paper" was used on a large scale, the habit of using "official documents" among the ruling classes had been finalized, and the ability to use "classical Chinese" had evolved into a symbol of reading and literacy. Classical Chinese comes from vernacular Chinese, characterized by writing based on words, paying attention to the use of allusions, parallel prose, neat rhythm and no punctuation, including strategies, poems, words, songs, stereotyped writing, parallel prose and ancient prose.
