In the ancient Chinese fable,"The Governor of Yuanmen", there was an idiom that described actions and goals as being exactly opposite. It meant actions and goals were completely inconsistent. In ancient times, there was a prefect called Yuanmen. His residence was far from the government, but he often went to the government to do business. One day, the Governor of Yuanmen heard that there was a matter that needed to be dealt with quickly, so he decided to go and deal with it. However, when he arrived at the government gate, he found that the gate was closed and there was no one inside. He turned to a door at the side, but it was also closed and there was no one inside. He realized that he had gone in the wrong direction, but there was no turning back. The story of the Governor of Yuanmen tells us that if the action and purpose are exactly the opposite, it is very likely that we will fall into a dead end and be unable to find the right direction. This idiom is also often used to describe situations where people make decisions and actions that are not in line with reality, such as choosing Plan B when Plan A could solve a problem.
