The Guangyun (Plantilla:Zh-cpw; literally "Broad/Extensive Rimes") is a Chinese rime dictionary that was compiled from 1007 to 1011 under the auspices of Emperor Zhenzong of Song. Chen Pengnian (陳彭年, 961-1017) and Qiu Yong (邱雍) were the chief editors. In the history of Chinese lexicography, the Guangyun stands between the Qieyun and the Jiyun.
It was originally split into five volumes, two belonging to the Middle Chinese Ping tone (平聲), one each for the other three Middle Chinese tones, Shang (上聲), Qu (去聲), and Ru (入聲). Each tone was split into rimes, and under each rimes were grouped characters of the same onset, and under each entry, was given a brief explanation of its meaning. The Guangyun has a total of 26,194 character entries, which are arranged under 206 final rimes, increased from 193 in the Qieyun (Teng and Biggerstaff 1971: 146).
