35.77

○王子喬者。靈王太子晉也。好吹笙作鳳皇嗚。道士浮丘公接上嵩山三十年。謂桓良曰。告我家。七月七日待我緱氏山。果乘白鶴舉手謝時人而去。

Prince Qiao was Crown Prince Jin of King Ling. He was fond of playing the mouth organ (sheng) to imitate the call of the phoenix. The Daoist Fuqiu Gong took him up Mount Song for thirty years. He said to Huan Liang: 'Inform my family to wait for me at Mount Goushi on the seventh day of the seventh month.' As expected, he mounted a white crane, raised his hands to bid farewell to the people of his day, and departed.
