《儀禮》嚮稱難讀。傳統以分節、繪圖、釋例爲治禮之法。三法之外，歷代禮家對《儀禮》筆法每有關注，卻未成系統。清代禮學大家吳廷華（1682-1755）著《儀禮章句》，其書於分節繪圖釋例三途，用力均篤，被譽爲“學禮者階梯”。吳書關注《儀禮》筆法，作經者的行文舖排、遣辭用字，每加析説，見解獨到。本文舉吳氏《章句》對《儀禮》筆法之意見凡十類，包括《儀禮》中的變文、行文語序、提示語、預陳其書、書有見無、省文、互文、相兼乃備、特定的虚詞等，各據例證。由於筆法每與禮例及禮意往往相須而成，吳氏對《儀禮》筆法的意見，與鄭、賈注疏互有異同，詮解出與注疏不同的禮經文本。藉此説明《儀禮》筆法應立爲專門之學，爲研治禮經之重要方法。

Yili 儀禮 (Book of Etiquette and Ceremonial) is considered a Confucians classic difficult to read. Scholars have adopted three basic methods of interpretation: (1) to break the texts into paragraphs; (2) to illustrate the ceremonies; (3) to explain the etiquette rules. In addition, scholars of different historical periods have also researched unsystematically on the writing style of Yili. This article examines Qing-dynasty scholar Wu Tinghua’s 吳廷華 (1682 1755) annotations to the writing techniques of Yili in his Yili zhang ju 儀禮章句 (Analysis of the Book of Etiquette and Rites) , including textual variation, words’ sequence, hint, pre-narration, indicating the hidden, omission, intratextuality, use of specific function words, etc. Because the writing techniques of Yili are related to the moral meanings of the etiquettes and their rules, the differences among Wu Tinghua’s, Zheng Xuen’s 鄭玄 and Jia Gongyan’s 賈公彦 annotations project a diversity of the actual performances of the etiquettes.
