Both criticism and creation of ancient poetry should pay attention to meter. The ancient poetic style before the Tang Dynasty is a poetic style that does not pay attention to meter and has no limitation on the number of words and sentences. After the Tang Dynasty, due to the appearance of modern poetry, poets deliberately imitated the writing style of ancient poetry in the Han, Wei and Six Dynasties in order to distinguish ancient poetry from new metrical poetry, and restricted it in some aspects, thus forming a fixed pattern of ancient poetry in the Tang Dynasty. As a result, the completely free poetic style before the Tang Dynasty was changed into a semi-free poem between metrical poetry and free poetry.
The writing performance of ancient poetry lies in:
1. Concise sentences
2. Peace and confrontation
3. Words and grammar
Therefore, writing and commenting should also pay attention to these. In addition, the creation of ancient poetry should also pay attention to artistic conception and modification techniques.
