亡羊补牢

亡羊补牢

战国时代，楚国有一个大臣，名叫庄辛，有一天对楚襄王说：“你在宫里面的时候，左边是州侯，右边是夏侯；出去的时候，鄢陵君和寿跟君又总是随看你。你和这四个人专门讲究奢侈淫乐，不管国家大事，郢（楚都，在今湖北省江陵县北）一定要危险啦！”

襄王听了，很不高与，气骂道：“你老糊涂了吗？故意说这些险恶的话惑乱人心吗？”
庄辛不慌不忙的回答说：“我实在感觉事情一定要到这个地步的，不敢故意说楚国有什么不幸。如果你一直宠信这个人，楚国一定要灭亡的。你既然不信我的话，请允许我到赵国躲一躲，看事情究竟会怎样。”

庄辛到赵国才住了五个月，秦国果然派兵侵楚，襄王被迫流亡到阳城（今河南息县西北）。这才觉得庄辛的话不错，赶紧派人把庄辛找回来，问他有什么办法；庄辛很诚恳地说：“我听说过，看见兔子牙想起猎犬，这还不晚；羊跑掉了才补羊圈，也还不迟。……”

是一则很有意义的故事，只知道享乐，不知道如何做事，其结果必然是遭到悲惨的失败无疑。

“亡羊补牢”这句成语，便是根据上面约两句话而来的，表达处理事情发生错误以后，如果赶紧去挽救，还不为迟的意思。例如一个事业家，因估计事情的发展犯了错误，轻举冒进，陷入失败的境地。但他并不气馁，耐心地将事情再想了一遍，从这次的错误中吸取教训，认为“亡羊补牢”，从头做起，还不算晚呢！

It is not too late to mend the fold even after some sheep have been lost

A man who raised sheep once noticed there was a hole in the walls of his sheepfold. But he neglected to repair it. A few days later, several sheep were missing. His friend advised him: "It is not too late to mend the sheepfold."

"Wang Yang Bu Lao" or "Mending the sheepfold after the sheep have been stolen" advises us that even though we have suffer a loss, it is never too late to take steps to prevent further losses.
