AKU Wuwu's poems, with its unique language style and image, have attracted increasing attention in world minority literature circles. Scholars at home and abroad focus more on the marginal position of literature, the identity of the author, and the uniqueness of minority culture but less on the poems itself. The purpose of this paper is to use Jacques Lacan's mirror image theory to analyze AKU Wuwu's poems, to explore how AKU Wuwu breaks Jacques Lacan's false image to seek truth from the inside and directly reach the ideological and spiritual level of literary life, and returns to the literariness of ethnic literature research.
