Research on the Unique Value of Wall Painting Art as a Non-Literal Carrier

As an immersive visual art deeply embedded in urban and rural public spaces, wall painting art breaks through the limitations of text carriers of expression and takes intuitive visual symbols, scene immersive experience, and public interactive attributes as its core features, becoming a very dynamic contemporary non-textual culture and emotional carrier. This article takes wall painting art as the core research object, relying on cultural memory theory, non-verbal communication theory and spatial narrative theory to analyze its differentiated advantages compared with traditional text carriers, and deeply explore its role in individual emotional comfort, collective memory cohesion, regional context inheritance, and urban and rural space. Activate the unique value of the four dimensions, sort out the practical difficulties existing in the current wall painting creation and application, such as homogeneity, superficiality, lack of long-term operation and maintenance, and isolation from public needs, and propose optimized paths for localized creation, connotative expression, normalized operation and maintenance, and universal participation. The research aims to improve the theoretical system of non-literal cultural carriers and provide theoretical support and practical reference for the construction of urban and rural public culture, the living inheritance of nostalgic culture, and the innovative application of public art.
