The Lyric focus on the inner world of people, while the narrative is an act of report about the external events. Therefore, we can find the worlds which are reproduced in the language through narratives and compare these worlds and the real worlds where we actually think and act. Often the narrative is divided into two categories, one is historical narrative and the other is fictional narrative. But in oral tale, it is difficult to distinguish between history and fiction. Oral tale is old traditional narrative which was passed on to people in a oral cultural system. People believe myths to be true, regard legend as historical fact. But the main feature of folk tale(民譚) is fictionality. It is difficult to confirm what is the historical text and what is the fictional text in the oral tales. Therefore when understanding narrativity of oral tale, it is necessary to research into the worlds and the relationships of these worlds which narrative texts being presented. The oral tales have very wide spectrum of possible world and that of the relationship. The aspects of connection between empirical worlds which are regarded as real world by the audience and the speaker in the community of tales and fictional worlds of the oral tales are as follows. The first is that empirical worlds and the fictional worlds are consistent. The second, fictional world become cause or result of empirical worlds or empirical worlds. Finally, the fictional world and the empirical worlds are combined depending on a particular law. These three types are related to the feature and law of three types of sign: icon, index and symbol.
