With the popularity of social media and instant messaging platforms, emojis, as a unique digital communication method, play an important role in modern social culture. As one of the most popular social platforms in China, WeChat is extremely frequently used in user interaction. This article aims to analyze the communication characteristics of emojis on the WeChat platform and explore the behavior patterns of users in the process of using emojis and their socio-psychological impact. This article reviews the cultural background and development process of emoticon packs and explores the process of emoticon packs evolving from an early symbol system to modern digital cultural symbols.
