Once a man wanted to go to the south, but his carriage was heading north. A passer-by asked him: “If you are going to the south, why is your chariot heading north? ” The man answered, “My horse is good at running, my driver is highly skilled at driving a carriage, and I have enough money. ” The man didn't consider that the direction might be wrong; the better his conditions were, the further he was away from his destination.
從前有個(gè)人要到南方去，他坐的車(chē)子卻向北方行駛。過(guò)路人說(shuō)：“你去南方，車(chē)子怎么向北行駛呢？”他回答說(shuō)：“我的馬很能跑路，我的車(chē)夫駕車(chē)的技術(shù)也很高明，加上我又帶了充足的路費(fèi)?！边@個(gè)人沒(méi)有考慮到，方向弄反了，他的條件越好，離他要去的地方就越遠(yuǎn)。

The idiom derived from this story indicates that one's action was the opposite effect to one's intention.
后來(lái)人們就把這個(gè)故事概括為“南轅北轍”，比喻一個(gè)人的行為和他的目的正好相反。
