Abstract: In the current context of sustained social development and increasingly frequent interpersonal communication, modern service industry has put forward higher requirements for the appearance and etiquette of talents. This study focuses on the application of digital technology in the teaching of body language and etiquette. Through analysis, it is found that the introduction of digital technology can significantly improve teaching efficiency, enhance students'immersive learning experience, and promote the development of personalized and self-directed learning modes. However, in current practice, there are still practical challenges such as insufficient technological integration, lagging teacher role transformation, uneven digital literacy of students, and privacy protection. Based on the above findings, this article proposes optimization strategies such as building an intelligent teaching resource library, constructing a digital teaching environment, and building a digital driven multidimensional evaluation system. The results indicate that by systematically leveraging the empowering role of digital technology, it can effectively promote students'understanding and internalization of etiquette knowledge, thereby promoting the comprehensive development of their etiquette literacy.
