中文摘要：

本文结合《花东》103版5、6辞中“亡后”一语的释读，对古后字形、音、义演化轨迹进行了讨论。认为后、司乃一字之分化，读为齿头音的“司”较为晚出，《花东》103版原释文中的“司”应该改释为“后”，在辞中读若前後之“後”。

We recognized that 后 and 司 came from the same origin, the latter one appeared more lately than the former, and its pronunciation are about tooth. We should change the old explanation of 司 to ＂后＂, use it as ＂後＂ .
