English Original
There was once a rich man in the State of Song. After a heavy downpour, his wall began to crumble.
"If you don't mend that wall," warned his son, "a thief will get in."
An old neighbor gave him the same advice, but the man paid no attention.
That very night, a great deal of his money was indeed stolen. Afterwards, the rich man constantly praised his son's intelligence, but he suspected his old neighbor of being the thief.

宋国曾有一位富人。一场倾盆大雨过后，他家的墙开始坍塌。
他的儿子警告说：“如果不修补这堵墙，小偷就会进来。”
一位老邻居也给了他同样的建议，但富人充耳不闻。
就在那天晚上，他果然失窃，损失了大量钱财。此后，这位富人总是称赞自己的儿子聪明，却怀疑那位老邻居就是窃贼。
