Liáo-dynasty Buddhist monk and lexicographer, zì Guǎngjì 廣濟, secular surname Yú 于. Active at the Mǐnzhōngsì 憫忠寺 in the Liáo Yānjīng (modern Beijing). His sole work, the Lóngkān shǒujiàn KR1j0036 (Tǒnghé 15 / 997, prefaced by his fellow-monk Zhìguāng 智光), is the only major character dictionary surviving from the Liáo dynasty — a four-juàn work with 26,430+ head graphs in a doubly-stratified four-tone organization (radicals four-tone-ordered, head-graphs within each radical four-tone-ordered). The work refines the zhèng / sú / tōng scheme of Yán Yuánsūn’s 顏元孫 Gānlù zìshū into a five-form scheme (zhèng / sú / jīn / gǔ / huòzuò). No CBDB or DILA Buddhist authority entry can be confirmed.
