Yupian


The Yupian is a c. 543 Chinese dictionary edited by Gu Yewang 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.
The Yupian is a significant work in the history of Written Chinese. It is the first major extant dictionary in the four centuries since the completion of Shuowen and records thousands of new characters that had been introduced into the language in the interim. It is also important for documenting nonstandard súzì, many of which were adopted in the 20th century as official simplified Chinese characters. For instance, the Yupian records that wàn had a popular form of, which is much easier to write with three strokes versus thirteen.
Baxter describes the textual history:
The original Yùpiān was a large and unwieldy work of thirty juàn , and during Táng and Sòng various abridgements and revisions of it were made, which often altered the original fănqiè spellings; of the original version only fragments remain, and the currently-available version of the Yùpiān is not a reliable guide to Early Middle Chinese phonology.

In 760, during the Tang dynasty, Sun Jiang compiled a Yupian edition, which he noted had a total of 51,129 words, less than a third of the original 158,641. In 1013, Song dynasty scholar Chen Pengnian published a revised Daguang yihui Yupian. The Japanese monk Kūkai brought an original version Yupian back from China in 806, and modified it into his c. 830 Tenrei Banshō Meigi, which is the oldest extant Japanese dictionary.
