Poetry can be divided into classical poetry and modern poetry according to rhythm. Classical poetry and modern poetry are concepts formed in the Tang Dynasty, which are divided from the perspective of poetic rhythm. From the metrical point of view, the poetic style after the Tang Dynasty can be roughly divided into two categories: modern poetry and ancient poetry. Modern poetry, also known as modern poetry, has certain meter. Classical poetry, also called archaic style, is written according to the practice of ancient poetry, and its form is relatively free, and it is not bound by metrical rules.
According to the content, it can be divided into narrative poems, lyric poems, farewell poems, frontier poems, pastoral poems, nostalgic poems (poems about history), event poems, mourning poems and allegorical poems.
