Yanjingshi ji (Chinese: ç Âç»Â室é or ; âÂÂCollection from the Studio for the Investigation of ClassicsâÂÂ, also translated as âÂÂCollection from the Studio of Studying the ClassicsâÂÂ, etc.) is a collection of the private writings of the Qing dynasty scholar-official and philologist Ruan Yuan é®堠(1764âÂÂ1849), first printed in 1823. Ruan Yuan was one of the most important editors and scholars of Confucian research during the reigns of the Qianlong Emperor (r. 1736âÂÂ1795) and the Jiaqing Emperor (r. 1796âÂÂ1820), and a leading figure of the so-called Qian-Jia School () of evidential scholarship.
The writings of his entire life are largely included in it, except for several works for which he served as the leading editor. The collection reflects his academic views and his methods of scholarship. Ruan Yuan was also the editor of an influential annotated edition of the Thirteen Classics (Shisanjing) and of the collection Huang-Qing jingjie ().
According to Fang Chao-ying the collection of Ruan YuanâÂÂs poems and short prose writings was printed in 1823 and divided into five sections, of which 29 juan consist of prose and 11 juan of verse. Two supplements were later added: one in 9 juan, printed in 1830, and another in 6 juan, printed in or after 1844. A separate selection of his poetry, entitled Yanjingshi shilu (æ ç¶Â室詩é / æ ç»Â室è¯Âå½Â), in 5 juan, appeared in 1833.
In a new Zhonghua Shuju edition the whole work is divided into three parts: Yanjingshi ji (æ ç»Â室éÂÂ), Yanjingshi xuji (æ ç»Â室ç»ÂéÂÂ, âÂÂSupplement/ContinuationâÂÂ), and Yanjingshi waiji (æ ç»Â室å¤ÂéÂÂ, âÂÂOuter CollectionâÂÂ), which together comprise 64 juan (volumes). The Waiji (âÂÂOuter CollectionâÂÂ) contains 173 summaries of works that were not included in the Siku Quanshu. Ruan Yuan himself stated that about half of these pieces were not entirely written by him.
The Hanyu da zidian, for example, uses for the a photographic reprint of the first edition of the original publication in the Sibu congkan series ().
