Tang poetry
Pailü (Chinese:  ,  ,  "páilǜ"; Cantonese: "Paai"4-"leot"6) is one of the main forms of Classical Chinese poetry. It is a style of regulated verse ("jintishi"): the rules and regulations of the "pailü" allow for a poem composed of an unlimited series of linked couplets. The "pailü" form seems to have developed as part of 7th-century Tang poetry.
