Piya
The Piya (Chinese:埤雅; pinyin:Píyǎ; Wade–Giles:P'i-ya; "Increased [Er]ya") was a Chinese dictionary compiled by Song Dynasty scholar Lu Dian (陸佃/陆佃, 1042-1102). He wrote this Erya supplement along with his Erya Xinyi (爾雅新義 "New Exegesis of the Erya") commentary. Although the Piya preface written by his son Lu Zai (陸宰/陆宰) is dated 1125, the dictionary was written earlier; Liu (1963:87) estimates around the Yuanfeng era (元豐, 1078–1085).
