Yupian

The Yupian (Chinese: 玉篇; pinyin: Yùpiān; Wade–Giles: Yü-p'ien; "Jade Chapters") is a circa 543 CE Chinese dictionary edited by Gu Yewang (顧野王; Ku Yeh-wang; 519-581) during the Liang Dynasty. It arranges 12,158 character entries under 542 radicals, which differ somewhat from the original 540 in the Shuowen Jiezi. Each character entry gives a fanqie pronunciation gloss and a definition, with occasional annotation.
