For this reason, Studying on how "exile" has an influence on arts and literate of the nobility is very significant and meaningful. Earlier studies on exile literature have developed in three ways. First, bibliographical studies, that is, studies of contents, writers and social background, have been conducted. Second, based on bibliographical researches, writers` inner conflicts have been investigated. Third, literal conceptualization of exile literature in an area that needs more research.
