啞啞而笑（上烏陌反顧野王云啞啞笑聲下私妙反說文大戴其竹君子樂然笑也經作㗛𠸍咲皆非本字傳寫誤）。

啞啞而笑 (Laughing ha-ha: the upper character has the fanqie 烏陌; Gu Yewang says 啞啞 is the sound of laughing. The lower character has the fanqie 私妙; the Shuowen says that having large bamboo is joyful, and the gentleman laughs with joy; the scripture writes it as 㗛, 𠸍, or 咲, none of which are the original character, but errors of transmission and transcription).
