What are the subject categories of ancient poetry?

Poetry is a unique style of writing in Chinese, with a special format and rhythm. Poetry can be divided into two categories: ancient style poetry and modern style poetry. Ancient style poetry and modern style poetry are concepts formed in the Tang Dynasty, and are divided from the perspective of the rhythm of poetry.

According to the subject matter and content, it can be divided into narrative poems, lyric poems, farewell poems, frontier poems, landscape pastoral poems, nostalgic poems (epic poems), mourning poems, poems chanting objects, military poems, etc. Ancient style poems include "The Book of Songs", "Chu Ci", "Yuefu", "Han Fu", "Folk Songs of the Southern and Northern Dynasties", etc. Modern poetry is generally composed of quatrains, rhymed verses, and arranged rhymes (long rhymes).
