larged edition of the "Kan-lu-tzŭ-shu" of Yen Yuan-sun (彥元孫) of the T‘ang period. The other was the "Han li-tzŭ-yuan" (漢隸字源), Sources of the Li characters in the Han literature. This is regarded as a trustworthy guide to the Li writing found in books and inscriptions of the Han dynasty and the Three Kingdoms. It gives the modern forms of the characters, their Li equivalents, adding the history and explanation of them.[1]
Another student of the language about this time was Lo Yuan (羅厚) al. Tuan-liang (端良) who was born in 1136 and died in 1184. He compiled a treatise to which he gave the name "Urh-ya-i" (爾雅翼) Wings, that is, useful additions to the "Urh-ya."
