One day, a big bad wolf was strolling by a river. Feeling suddenly hungry, it caught five large fish.
However, the wolf ate too quickly, and a fishbone got stuck in its throat.
A red-crowned crane was passing by and saw the wolf struggling with the bone. Without a second thought, it approached the stream to help.
The crane approached the wolf and asked, "Mr. Wolf, what's wrong? Are you stuck with a fishbone? If so, let me help you peck it out!" the crane offered earnestly.
The crane added, "I can help you, but you must not repay kindness with ingratitude!" The wolf struggled and replied, "I know, I know! Just hurry up and get the bone out! I'll agree to any condition!"
The crane agreed and carefully pecked the bone out of the wolf's throat. To its surprise, the wolf actually tried to betray it. Fortunately, a little white rabbit saw what was happening and shouted, "Watch out, Sister Crane! The big bad wolf is going to eat you!" Hearing this, the crane quickly flew away. Enraged, the wolf turned to chase the rabbit. Luckily, the rabbit was fast and had prepared in advance; it had asked a puppy to dig a hole and hid inside it. In the end, the wolf got lost in the forest, and no one was willing to help it when it cried for rescue.
The moral of the story is: One should never be ungrateful or betray those who help. Only by being grateful will others be willing to help and trust you.
一天，大灰狼在小河边散步，忽然觉得很饿，于是捉了五条大鱼。
可是大灰狼吃得太快了，结果鱼刺卡在了它的喉咙里。
丹顶鹤正准备经过此地，恰好看到被鱼刺卡住的大灰狼。它没有多想，便走到小溪边准备帮助大灰狼。
丹顶鹤走到大灰狼身边问道：“狼先生，你怎么了？是不是被鱼刺卡住了？如果是的话，让我帮你啄出来吧！”丹顶鹤真诚地提议道。
丹顶鹤接着叮嘱：“我可以帮你，但你千万不能恩将仇报！”大灰狼痛苦地挣扎着说：“知道了，快帮我把鱼刺弄出来吧！任何条件我都答应你！”
丹顶鹤答应了，并细心地帮大灰狼将鱼刺啄了出来。谁知大灰狼竟然真的恩将仇报。这时，一只小白兔恰好看见了这一切，大声喊道：“丹顶鹤姐姐小心！大灰狼要吃你了！”丹顶鹤听到提醒，赶紧振翅飞起。大灰狼气急败坏，转身去追兔子。幸好兔子跑得快，且早有准备，它请小狗提前挖了一个洞，随后钻进洞里躲了起来。最终，大灰狼在森林里迷了路，再怎么求救也没有人愿意理会它了。
这个故事告诉我们：人不能背信弃义，更不能恩将仇报。只有知恩图报，别人才会愿意帮助并信任你。
