Abstract: The postcolonial theory, as a perspective, has a kind of openness to integrate with other perspectives, because the revelation of the postcolonial world is not for the purpose of preserving the past, but for reshaping the future. Taking novel To Kill a Mockingbird as an example and focusing on the special connection between the child’s perspective and postcolonial criticism that has been overlooked in previous research, this article uses the child’s perspective to remove and transcend the postcolonial theory of binary opposition. In fact, with the help of a child’s perspective, the colonial world was able to re-reconsider its complex human nature and social relationships, which also meant that people in colonial history regained themselves, freed themselves from the colonial discourse of the original world, and gained growth. The childlike mockingbird is a breaking fog lamp for the new self to achieve transcendence over the old self, providing an opportunity for the conflicting self to make new value choices, soothing the hurt and insulted souls of the past, and truly achieving reconciliation and harmony with the old self and the old world.
