姜質〈庭山賦〉既非名家名作，甚至文辭粗鄙，卻被文學造詣頗高的楊衒之全文引錄於《洛陽伽藍記》，此弔詭現象不僅引發近代學者多所臆測，也誘使本文商量舊學之興趣，進而探究楊氏之所以引錄與其信念價值判若雲泥的〈庭山賦〉，實乃史家一筆兩寫之敘述策略，藉此諷刺擾亂綱紀的權臣及阿附權貴的逢迎小人。就楊氏撰書之時間點而言，當時氣焰囂張、無視禮法綱系己的高歡父子及阿諛順旨、奉詔撰史的魏收，恰符合此兩類形象。

Composed by a little-known writer Jiang Zhi, ＂Ting Shan Fu＂ presents a poor language and rough rhetoric skills. However, such work was full-text cited in ＂Luoyang Qielan Ji＂ by Yang Xuanzhi, who achieved high literary performance. This paradoxical phenomenon has triggered considerable assumptions among scholars in recent years and elicited the motivation of this study in discussing the old learning. This study explored Yang's motive for citing ＂Ting Shan Fu＂, which presents content contradictory to Yang's belief and value, and determined that such citation was a historian descriptive strategy of implying double meanings in a passage to ironize the officers who held power but breached legal principles and low-dignity people who were obedient to authorities. Considering the time when Yang composed ＂Luoyang Qielan Ji＂, the arrogant Gao Huan family who despises legal principles and Wei Shou who edited history by conforming to the emperor's order exactly met the characteristics of breaching legal principles and low dignity.
