Quatrains (poetic genre)

Quatrains, also called truncated sentences, broken sentences and quatrains, are short and pithy. It is a popular poetry genre in China in the Tang Dynasty, and it belongs to a form of modern poetry.

Jue means "cut off", and the ancients used four poems with four quatrains to complete an ideological concept. There are two types of quatrains: quatrains and archaic styles. Rhythm only needs to be refined after the rise of rhythmic poetry. Ancient times existed long before the appearance of metrical poems.
