By sorting out relevant literature, this article defines the concept and classification of service rituals. Service rituals can enhance consumer experience, enhance customer-enterprise relationship and promote brand value, and the cultural background of consumers will affect their service ritual experience. At the end of this paper, the future research directions of service rituals are proposed.
