In Zhuangzi's "Free and Easy Wandering," a legendary fish of the Northern Sea transforms into a magnificent roc whose wings, when fully opened, block out the sun like a cloud. When the wind rises in June, a trail of spray accompanies the legendary bird as he flies toward the Southern Sea with his wings skimming the surface of the ocean.
莊子〈逍遙遊〉裡，北海的鯤化身巨大鵬鳥，展翅若雲遮蔽天空，而當六月風起，鵬鳥雙翼拍打海水，激起水花三千里，伴隨大鵬往南海而去。
