Since the 60 s of the 20th century, scholars home and abroad have shown interest in studying metaphor translation and looking for the guiding principles. So far four periods have been recognized, that is, the preparatory period, the primary period, the theory-building period, and the period of textualization and individualization. It is also recognized among the scholars that metaphor translation can be studied either from the perspective of the original language or that of the target language. So far as relevant theories are concerned, metaphor translation can be guided by rhetoric, componential analysis, textual analysis, pragmatics, culturalism, and cognitive linguistics.
