The Kanmiu Buque Qieyun (Ã¥ÂÂ謬è£Â缺åÂÂé») by Wang Renxu (çÂÂä»ÂæÂ«), which was published in 706, is the oldest extant Chinese rime dictionary. For many centuries, it was believed to be lost, until a copy was found at the imperial palace in Beijing in 1947. Lóng 1968 published an eye copy with annotations. Zhou 1983: 434-527 includes a facsimile of the original, which is not very legible.
There are three versions of KÃÂnmiù BÃÂquàQièyùn, which are typically distinguished by numerals, known as çÂÂä¸Â, çÂÂäºÂ, and çÂÂä¸Â.
The first version, çÂÂä¸Â, is known only from a Dunhuang manuscript fragment (P. 2011). The second, çÂÂäºÂ, is also called XiàngbábÃÂn 项è·ÂæÂ¬, because it contains a postscript by Xiang Yuanbian, or PéiwùqàZhèngzìbÃÂn 裴å¡é½ÂæÂ£åÂÂæÂ¬. The third version, çÂÂä¸Â, is also referred to as Quánwáng å ¨ç (because it is complete), Gùgà ÂngbÃÂn æÂ å®«æÂ¬ (because it was found in the Palace Museum), or SòngbábÃÂn å®Âè·ÂæÂ¬ (because there is a postscript by Song Lian). Generally speaking, the first and third versions are most alike, whereas the second is more distinct, and it is often considered to be a combination of KÃÂnmiù BÃÂquàQièyùn Ã¥ÂÂ谬补缺åÂÂéµ by Wang Renxu per se and JiÃÂnzhùbÃÂn Qièyùn 笺注æÂŒÂÂéµ by ZhÃÂngsà «n Nèyán é¿åÂÂè®·è¨Â, maybe S. 2055 (Zhà Âu ZÃÂmó å¨ç¥Âè°Â, 1983; Tóng XiÃÂolÃÂn ä»Âå°Âç³, 2008).
