The second section of the text "Xinian" 繫年 of the Tsinghua Collection of Bamboo Manuscripts recorded the historical transition from the Western Zhou to the Eastern Zhou. Towards the end of the section, there is a line that caught the attention of scholars: "King Wen of Chu expanded territory in Hanyang" 楚文王以啟于漢陽. After examining the various interpretations, this paper raises three questions: firstly, whether there is a lacuna in this line and if so, is shi 始 the missing word here; secondly, whether there is a connection between the line in question with the purport of the second section of the "Xinian," and thirdly, is there a connection between King Wen of Chu "expanded territory in Hanyang" and the area he took up residence. The paper proposes that Hanyang was both a directional indicator and geographic name. After reviewing several views on the approximate geographic range of Hanyang by previous scholars, the author moves on to analyze the early occurrences of the term in transmitted literature and expresses his own view on the matter.
