There was once a rich man in the State of Song. After a downpour of rain his wall began to rumple.

"If you don't mend that wall," warned his son, "a thief will get in."

An old neighbour gave him the same advice. But he paid no attention to it.

That night, indeed, a great deal of money was stolen. Then the rich man praised his son's intelligence all the time, but suspected his old neighbour of being the thief.

宋国有一富人，一场倾盆大雨过后，自家的墙开始坍塌。

他儿子提醒说：“如果墙不补，小偷就会进来的。”

他的一位老邻居也在提醒他，可这位富人却充耳不闻。

果真就在那天晚上，这个富人失窃，损失了很多钱。从此，富人老是在夸自己的儿子很聪明，而怎么看老邻居，都觉得他像偷了钱的贼。
