Jueju
Jueju (traditional Chinese: 絕句; simplified Chinese: 绝句; pinyin: juéjù), or Chinese quatrain, is a type of jintishi ("modern form poetry") that grew popular among Chinese poets in the Tang dynasty (618–907), although traceable to earlier origins. Jueju poems are always quatrains; or, more specifically, a matched pair of couplets, with each line consisting of five or seven syllables.
