The Tension of National Allegory by Mr. Nie Mao, standing in the globalization theory frontier, combined with the specific context of situation and the native culture of China, uses the western discourse to interpret Chinese literature in the new period. It is not only “decoding” of the classical texts of each literature trend , but also the “ pulse-taking interpretation” of the characteristics of creative groups in each period, hoping to obtain a “diachronic depth”, a “synchronic breadth” and a three-dimensional “thickness”. Through this fine interpretation, Mr. Nie Mao displays the original meaning hidden in the piles of materials to the maximum degree. In his eyes, the joint efforts made by Chinese literature creation groups in the new period not only impacted the “free thought” of cultural hegemony in the first world, but also repaired, enriched and developed the western discourse system itself, hence the significance of Chinese literature in the new period can not be ignored in the world literature.
