Yang Kui and Chen Ying-Zhen pay much attention to the theoretical contribution in reportage. On the premise of no fiction,reportage emphasizes the author's attitude and trend while the artistry and literariness cannot be ignored, which makes it distinguished from other news writing. This may provide theoretical guidance for the reportage works published in Renjian. Guan Xiao-Rong deals with the polemical relationship between subjectivity and objectivity in reportage. Zhong Qiao is good at theoretical thinking. His praxis fulfilled Yang Kui's thoughts and observations two in one. He establishes the third world consciousness in the activity of the Asian People's Theatre. The inheritance of theories and creative experience of Taiwan Left-wing Reportage have a great influence on the development of reportage as a type of writing.
