Abstract: As a unique symbolic function, language landscape conveys the spillover effect of "cultural self-confidence". Its cultural translation and dissemination is a full affirmation and positive practice of its own cultural value. Based on the in-depth translation theory, this paper explains the regional culture carried by the language landscape from the perspectives of implicit translation of language landscape text, marginal annotation of language landscape and explicit annotation of cultural capital, in order to enrich tourists' sense of cultural experience, enhance cultural exchange and acceptance, and expand the dissemination of cultural information.
