A man named Ch’i Hsieh（齐谐），who recorded novel occurrences，said：“When theP’eng is moving to the Southern Ocean，it flaps along the water for three thousand li.Then it ascends on a whirlwind up to a height of ninety thousand li，for a flight of six months’ duration.”
“Since the wings are large，they are difficult to move.They must mount upon a whirlwind in order to get up，and must get to the height of ninety thousand li，in order to be supported by the air.Since the p’eng has such wings，how can it suddenly get up，and get down at the height of tens of feet？Thep’eng has its own way of doing things，because of necessity，not because it likes to.The large bird flies with a duration of half a year and stops at the Celestial Lake.The small bird flies with a duration of half a morning and stops at the trees.If we compare their ability，there is a difference.But what each does is proper to its own nature；in this way are the same.” —Kuo Hsiang
