This paper explores the upper and lower contexts of the literature, and examines the meaning that the context intends to say and the era indicated by '古'. This not only helps to objectively and concretely recognize and interpret the "old" era, it can also be used to dig deeper into the meaning of the literature. In particular, such research is expected to play an even greater role in the literature that needs to clarify historical facts. '古' can be specified differently depending on the literature. In this paper, in particular, focusing on this point, in order to examine more closely how the periodic interpretation of '古' was done, the interpretation and usage examples of '古' were intensively examined. Notable items in the meaning of '古' are the meanings of beginning, ancestor, always, forever, and so on. In particular, in historical literature, the first beginning of civilization was viewed as 'old'. It is emphasized that the age of pay wages is viewed as the "old" at the base point.
