亡羊补牢

一yí个人gè rén养yǎng羊yáng，羊yáng圈quān破pò了le个gè洞dòng，夜里yè li狼láng进来jìn lái叼diāo走zǒu了le一yì只zhī羊yáng。

A shepherd's pen had a broken hole; at night a wolf took a sheep.

邻居lín jū说shuō：快kuài修xiū羊yáng圈quān吧ba。他tā说shuō：羊yáng都dōu丢diū了le，修xiū有yǒu什么shén me用yòng？

A neighbour said: fix the pen. He said: the sheep is already lost, why bother?

第dì二èr天tiān夜里yè li，狼láng又yòu从cóng洞dòng里lǐ进来jìn lái，叼diāo走zǒu一yì只zhī羊yáng。

The next night the wolf came through the hole again and took another.

他tā后悔hòu huǐ了le，马上mǎ shàng把bǎ羊yáng圈quān修xiū好hǎo。从此cóng cǐ，他tā的de羊yáng再也zài yě没有méi yǒu丢diū过guò。

Sorry at last, he mended the pen. No sheep was ever lost again.

出chū了le问题wèn tí马上mǎ shàng改gǎi，还hái不算bú suàn晚wǎn。

Fixing a problem the moment you see it is never too late.
