例1：是鸟也，海运则徙于南冥。南冥者，天池也。（《逍遥游》）
冯译郭注：The p’eng cannot move itself，unless in the ocean.The air cannot bear its wings，unless it reaches to a height of ninety thousand li.The p’eng is not doing so for the sake of curiosity.It does so simply because large things must live in a large place；and in a large place，large things must be produced.
例2：鹏徙于南冥也，水击三千里，抟扶摇而上九万里，去以六月息者也。（《逍遥游》）
冯译郭注：Since the wings are large，they are difficult to move....The p’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 they are the same.[12]
