Paijing 牌經, also called Madiao paijing 馬弔牌經, is a book on a card game written by Long Ziyou 龍子猶, who is none other than the great novellist Feng Menglong 馮夢龍 (1574-1646). With 13 chapters, the book imitates the classic of military strategy, Sunzi bingfa 孫子兵法. It advises on tactics for a card game (paixi 牌戲), but also describes the standard rules of the game. Being written by a famous writer, the text is refined, but still clear.
The text is found in the series Chongding xinshangbian 重訂欣賞編 and Shuofu xu 繼說郛.
