Wu Song
Some of the outlaws who appear in the famous novel "The Water Margin", such as Wu Song, were experts in this style; this is why Chuojiaoquan was alternately known as the "Water Margin Outlaw style". It is also known as "Yuānyāng Tuǐ" (鴛鴦腿) or "Mandarin Duck Leg." In "The Water Margin"'s 28th chapter, entitled "Drunken Wu Song beats Jiang Menshen innkeeper", it mentions that Wu Song uses the following moves: "step of nephrite ring, leg of mandarin duck".
