Classical 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.
In addition, ancient quatrains also had authors in the Tang Dynasty. All belong to the category of ancient poetry. In the process of development, classical poetry and modern poetry have an interactive relationship. In the late Northern and Southern Dynasties, a new style of poetry appeared, which emphasized rhythm and duality, but had not yet formed a complete rhythm, and was between classical poetry and modern poetry. Some ancient poems in the Tang Dynasty tend to be legalized, and even ancient works are often integrated into modern sentence patterns. However, there are also some ancient poetry writers who consciously distinguish themselves from the near-body, and often use awkward sentences or occasional essays to avoid the law.
