從生存狀態和生存體認出發，“離散”概念的外延，可以延伸到“離散意識”，以及與它相對的“回歸意識”這一層面。而離散的主體，則可以延伸到中國古代士人這一群體。自故鄉—政治文化中心離散，期盼回歸到故鄉—政治文化中心，構成了中國古代士人離散—回歸意識的核心内涵。這裡的“故鄉”，除了故土家園之外，還具有理想、歸宿或者精神家園的含義：所謂“此心安處是吾鄉”。古代中國士人“離散—回歸”意識的獨特内涵，及其文學書寫的獨特風貌，便是由上述質素構成、影響和造就的。從貶謫文學的視角看，貶謫帶來的離散，具有不可忽視的文化價值。

From the living state and survival awareness, the extension of the concept of “diaspora” can be extended to “diaspora consciousness” and its relative “regression consciousness”. Meanwhile, the subject of diaspora can be extended to the group of Chinese ancient intellectuals. Leaving from hometown-political cultural center and looking forward to return to hometown-political cultural center constitutes the Chinese ancient intellectual’s core connotation of the diaspora-regression consciousness. Here the “hometown” is not only the meaning of homeland but also includes the connotation of the ideal, destination or spiritual home: the so-called “Wherever my heart is at peace is my home”. The characteristic connotation of the “diaspora-regression” consciousness of the Chinese ancient intellectual and the unique style of their literature writing are composed, influenced and created by the above factors. From the perspective of relegation literature, the diaspora which brought by the relegation has the cultural value that can not be ignored.
