在后殖民理論視角下，"文化翻譯"不僅指跨語言文化的文本轉換，還涉及到人在不同文化間旅行的狀態及過程。心懷鄉愁的華人離散族群在家國之外從未停止過書寫、翻譯、演繹和傳播中國故事。他們跨越"自我"和"他者"的文化離散體驗能更好地幫助其協調文化異質性和可譯性之間的關系。本文通過研究離散族群在多元文化沖擊下展現的中國與世界的對話方式，指出他們基于不同的文化身份認同訴求，采取了不同的策略來展現中國元素和中國想象，用回歸、回望、重塑等不同形式守望了鄉愁。本文認為離散譯者的文化使命是要以更開放和自信的文化心態向世界說明中國，當好讓中國文化擁抱世界的文化導游。

In the perspective of post- colonial theory,"cultural translation"not only refers to cross-cultural text transformation between two languages,it also involves the state of diasporas in their cross- cultural travel and migration process. The diasporic translators have never stopped writing,translating and performing Chinese stories away from their home country for their homesickness. Their cultural diasporic experience across "self"and "other"can help them coordinate the cultural transition between cultural heterogeneity and accessibility. Through a study on the interactive modes between China and the world under the impact of diverse cultures presented in the diasporic translators’ works,this paper points out that they adopt different strategies to represent the Chinese factors and imaginations in their works based on their different appeals for cultural identities,and they use such ways as returning,retrospecting and remolding to keep their homesickness. It is believed that the cultural mission of disaporic translators is to illustrate China to the world with a more open and confident cultural mind and guide the Chinese culture to embrace the world.
