Pailü
Pailü ( Chinese: t , s , p páilǜ; Cantonese: Paai-leot) 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.
