挥手 waving hand

含义说明

挥手。使用场景：群里打招呼“大家早👋，今天上线”、下班告别“先走一步👋”、或退群/结束对话“先撤了👋”；离职退群、项目群收尾时也常用“就此别过👋，江湖再见”。情绪强度：表达轻松的问候与告别，语气友好随意，强度低——纯礼节性信号，不带强烈情绪，常用于开启或结束一段聊天而不打扰别人，轻松不尴尬。易混淆对比：👋 是挥手打招呼/再见，🫡 是敬礼式“收到”，🙌 是举手欢呼；👋 最轻，🫡 正式硬核，🙌 热烈。

A waving hand for casual hellos, goodbyes, or entering a chat—"morning everyone 👋", "heading out 👋". Its tone is light and polite, a low-intensity courtesy with little emotion. Compare it to 🫡 (a formal salute/acknowledgment) and 🙌 (enthusiastic raised hands); the wave is by far the most casual.
