Li Po (Rihaku) who heard a report that Nakamaro died in the storm wrote a shichigon zekku (a Chinese poem of four lines, each of seven characters), titled '哭晁卿衡' (wailing over the death of Nakamaro), one of which lines reads '明月不歸沈碧海' (a bright moon did not go back but sunk in the blue ocean), expressing Li Po's mourning over the death of Nakamaro.
このとき李白は彼が落命したという誤報を伝え聞き、「明月不歸沈碧海」の七言絶句「哭晁卿衡」を詠んで仲麻呂を悼んだ。
