如果聚集的水不深,那么它就没有负载一艘大船的力量了。在堂前低洼的地方倒上一杯水,一棵小草就能被当作是一艘船,放一个杯子在上面就会被粘住,这是水浅而船却大的原因。如果聚集的风不够强大的话,那么负载一个巨大的翅膀也就没有力量了。因此,鹏在九万里的高空飞行,风就在它的身下了,凭借着风力,背负着青天毫无阻挡,然后才开始朝南飞。
If there do not have enough water, big boatcan not float. If you put a cup of water on the ground in front of house, a grasscan float on the water like a boat, but a cup can not, because it is tooshallow and the cup is too big. If there do not have strong wind, wing will nothave tremendous strength. So, rocs can fly in the higher sky freely, withstrong wind, then it will fly to south.
