Antique refers to the four-character archaic poems mainly based on The Book of Songs/Sao-style poems represented by Li Sao, Yuefu poems represented by Han Yuefu and five-character archaic poems represented by Nineteen Ancient Poems.
Modern poetry has quatrains and exorcism poems, such as five-character quatrains, seven-character quatrains, five-character quatrains and seven-character quatrains.
Ci-Qu is a style juxtaposed with poetry.
