1. Ancient poems pay attention to the harmony of phonology and rules of meter in form. Ancient poems (such as four-character poems in the Book of Songs and Sao-style poems in Chu Ci) and modern poems (such as five-character quatrains, five-character quatrains, seven-character quatrains, seven-character quatrains, etc.) all have fixed word numbers and rhythm patterns. Modern poetry, in particular, strictly abides by the principle of "level and level" and requires strict tone collocation within and between poems.
2. The language of ancient poems is refined, often expressing rich connotations with fewer words, pursuing the artistic effect of controlling complexity with simplicity, and the content is highly concentrated. When narrating or expressing feelings, we often adopt a leap-forward thinking structure, do not stick to linear narration, and construct artistic conception through hints, symbols and other means.
3. Ancient poetry is good at creating artistic conception with the help of concrete description, with a strong sense of picture, and readers can feel the emotional world beyond the surface of words through the life scenes described by the poet. The beauty of artistic conception is a major feature of ancient poetry. There are paintings in poetry and poems in painting, which closely blend natural scenery, character activities and the author's emotions.
4. Ancient poems can be divided into narrative poems and lyric poems according to their contents, and they cover a variety of themes, such as chanting history, chanting things, pastoral landscapes, frontier battles and so on. According to different stylistic features, ancient poetry also includes ci, Sanqu and other forms, each with different artistic rules and aesthetic standards.
