《庄子·杂篇·庚桑楚》
口能含车的巨兽，孤零零地离开山野，那就不能免于罗网的灾祸；口能吞舟的大鱼，一旦被水波荡出水流，小小的蚂蚁也会使它困苦不堪。
夫函车之兽，介而离山，则不免于网罟之患；吞舟之鱼，荡而失水，则蚁能苦之。
A giant beast that can hold a chariot in its mouth leaves the mountains and fields alone and cannot escape the disaster of the net; a big fish that can swallow a boat is once washed out of the water by the waves, and even small ants will make it miserable.
