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.
从前有个人要到南方去，他坐的车子却向北方行驶。过路人说：“你去南方，车子怎么向北行驶呢？”他回答说：“我的马很能跑路，我的车夫驾车的技术也很高明，加上我又带了充足的路费。”这个人没有考虑到，方向弄反了，他的条件越好，离他要去的地方就越远。

The idiom derived from this story indicates that one's action was the opposite effect to one's intention.
后来人们就把这个故事概括为“南辕北辙”，比喻一个人的行为和他的目的正好相反。
