“南辕北辙”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 didnt consider that the direction might be wrong; the better his conditions were,the further he was away from his destination.The idiom derived from this story indicates that ones action was the opposite effect to ones 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.
