欻然（上熏鬱反𦵮綜注西京賦云欻忽也文字典說云欻者忽起皃也說文云有所吹起也從欠炎聲）。

Suddenly (欻然: the first character [欻] is fanqie 熏鬱 [xū]. Xue Zong's commentary on the Xijing fu says: "欻 means suddenly." The Wenzidian shuo says: "欻 denotes the appearance of rising up suddenly." The Shuowen says: "Something blown upward." It is formed with the yawn radical [欠] and 炎 as phonetic).
