From Li Bai's (
李白) Tang-dynasty
《上李邕》 (To Li Yong), paraphrasing the Peng bird fable of
《庄子·逍遥游》 (Zhuangzi: Free and Easy Wandering). Full couplet:
大鹏一日同风起,扶摇直上九万里 - 'one day the great Peng rises with the wind, riding the whirlwind straight up ninety thousand li.' Zhuangzi's original describes the Peng's flight as
抟扶摇而上者九万里.
