Abstract: Based on the literature on misty poetry theory in the history of modern Chinese poetry over the past century,the paper proposes for the first time the establishment of the “misty poetics theory” in Chinese new poetry.It is not an abstract theoretical hypothesis,but rather a historical generalization and theoretical interpretation of misty poetry theory’s content across different periods of modern and contemporary times.That is,it refines and elucidates the historical “Misty Poetics” into “Misty poetics theory”.The main theoretical tenets include:“mistiness” serves as a crucial pathway for poetic creation in new poetry and an important aesthetic pursuit in new poetry writing,in essence,mistiness embodies beauty.And as a historical form,the “Misty Poetics Theory” encompasses existing views that misty semantics are obscure,but as a theoretical form,it necessitates reflection and vigilance against semantic obscurity theory.While,the “Misty Poetics Theory” in new poetry belongs to the realm of communication and reception theory,requiring a scientific approach to the complex relationship among readers,poets,and new poetry texts,fully respecting readers’ responses and advocating for the cultivation of new poetry readers with subjective character and creative reading consciousness.In a word,the “Misty Poetics Theory” in new poetry is a novel poetic theory developed after Chinese poetry entered modern society.It should be integrated into the theoretical system of Chinese poetics,using its modern characteristics to activate the inherent vitality of traditional Chinese poetics,and enrich and develop it further.
