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』.
