Xu shen in his shuowenjiezi analyzed that 䯣(kui), 䰎(kui),嘳(kui), 匱(gui), 餽(饋)(kui), 鞼(gui), 蕢(kui), 樻(kui), 聵(kui), 憒(kui), 闠(hui), 繢(hui), 潰(kui), 殨(kui), 䜋(hui), 遺(yi), 穨(tui), 隤(tui), 僓(tui) should be pronounced following the phonetic sound of 貴(gui); however, in the rhyming categories in the pre-qin period, 貴(gui), 匱(gui) and 潰(kui) should rhyme with characters in wu rhyme group, while 遺(yi), 穨(tui) and 隤(tui) with wei rhyme group, totally different. as a matter of fact, the characters 貴 and 遺 originated differently. The character 貴 follows the phonetic sounds of 貝 and 臾(the protoform of 簣), while the core part of 遺 is the combination of 小(xiao) and (ju), which is irrelevant with the character 貴. Therefore, the old chinese phonology of 遺(yi)-prounced characters and 貴(gui)-pronounced characters should be reconstructed separately. The thesis proposes the following reconstruction based on zheng-zhang shangfang(2003):
Characters in yi-pronounced group: 遺(以追切 *lul / 以醉切 *luls, 穨(杜迴切 *l’u:l), 隤(杜迴切 *l’u:l), 僓(吐猥切 *lhu:lʔ)
Characters in gui-pronounced group: 䯣(丘愧切 *khruds), 䰎(丘愧切 *khruds), 嘳(丘愧切 *khruds / 苦怪切 *khru:ds),匱(求位切 *gruds), 鞼(求位切 *gruds / 公迴切 *klu:d),蕢(求位切 *gruds / 丘愧切 *khruds), 樻(求位切 *gruds / 丘愧切 *khruds), 貴(居胃切 *kluds), 聵(五怪切 *ngru:ds), 憒(古對切 *klu:ds), 闠(鬍對切 *glu:ds), 繢(鬍對切 *glu:ds), 潰(鬍對切 *glu:ds), 殨(鬍對切 *glu:ds), 䜋(鬍對切 *glu:ds / 鬍罪切 *:glu:dʔ), 僓(鬍對切 *glu:ds)
Meanwhile, william baxer and laurent sagart(2014) put forward the following modified reconstruction:
Characters in yi-pronounced group: 遺(以追切 *ruj), 隤(杜迴切 *n-rʕuj)
Characters in gui-pronounced group: 匱(求位切 *grut-s ), 貴(居胃切 *kut-s)
