Cunning often outwits itself.
鹅和鹤
The Geese and the Cranes
鹅和鹤在同一块草地上吃草，突然来了一个捕鸟人。轻巧的鹤很快飞走了。身体沉重的鹅，动作缓慢，还没来得及飞，就成了俘虏。
弱者需要加倍小心。
The Geese and the Cranes were feeding in the same meadow，when a birdcatcher came to ensnare them in his nets. The Cranes，being light of wing，fled away at his approach；while the Geese，being slower of flight and heavier in their bodies，were captured.
The more vulnerable need to watch more closely.
