WeChat is a popular social media application developed in China and designed for the mobile phone. Users may send and receive messages in a variety of systems, including text, emoji, gif files, pictures, and audio messages. They may create messages in one or more languages and code systems, and may interact asynchronously, or synchronously. For this study, we examined data in the form of messages shared using the “Chat” function of WeChat. Our analysis demonstrates how both WeChat as a technology and Chinese as a language afford novel and creative ways to construct messages and interactions. Users may write messages in non-standard, vernacular forms of Chinese, Cantonese; they may purposefully select incorrect characters to key and accent messages. By working carefully with untransposed data, and demonstrating user-generated methods of interaction, we show the limits of traditional CA, and point to new ways to expand and further methods of analyzing new forms of online data.
