When "Ju zhi wang tianxia (The kingship of various rulers)" was published in Zhanguo Chu zhushu collected by Shanghai Museum (9), the editor Pu Maozuo divided its contents into five chapters, namely "Gu Gong jian Taigong Wang (The Old Duke visits the Grand Duke Expected)", "Wen Wang fang zhi yu Shangfu ju zhi (King Wen enquires about raising and governing from Shangfu", "Yao wang tianxia (The kingship of Yao)", "Shun wang tianxia (The kingship of Shun)", and "Yu wang tianxia (The kingship of Yu)". After that, not only the scholars specializing in reading and explanation of individual words successively made the related discussion, many scholars also suggested making correction of the brief preface. One of these comments indicated that except "Gu Gong (the Old Duke)" being mentioned in three sections of "Gu Gong jian Taigong Wang", it had no connection with the contents of the remaining chapters. Therefore, after the original explanation was arranged, the scholars generally did not raise objection to the brief preface. In view of this, the discussions of this paper will review the scholars' comments on the explanation of the related words, and will also present the researcher's personal viewpoints.
