What is the story of this idiom handed down from ancient China?

Carving a boat for a sword is an idiom evolved from fable. I wonder if you have heard this story in your daily life. This idiom comes from Lu Chunqiu Chajin. We usually use this idiom to describe people who only know how to stick to the rules, then stick to the rules, stick to their own opinions and don't know how to be flexible. This word is often used as a derogatory term. It doesn't matter if you don't know the story very well. Next, Bian Xiao will tell you about it.

First of all, the background of this story is in the Warring States period. At that time, there was a man in Chu who wanted to cross the river by boat. As a result, when the ship reached the center, the Chu man accidentally dropped a sword he was carrying into the lake. He is in a hurry and wants to get him out quickly. As a result, it was useless to work for a while, because the sword fell into the water and slowly sank into the water, and everyone on board felt very sorry. It's no use trying to persuade him, but the Chu man seems confident. He immediately took out a knife and carved a mark on the rope of the bed. He also told everyone that this was the place where his sword fell into the water, so he had to mark it, but he must be very sad to think that his sword had fallen, so he didn't ask him again.

Secondly, after the ship landed, the Chu people immediately went into the water to look for his sword in the marked place on the ship. As a result, they didn't find their sister for a long time, which was very strange. They said to themselves that his sword fell from here. Why is it marked here but he can't find it? Hearing what he said, everyone around him said with a smile, the ship has been moving, but your sword has sunk to the bottom of the water and will not move with the movement of the ship. How can you find your sword?

Finally, the truth contained in this story is that people's thoughts do not conform to objective reality, and what they want to do will not succeed. Then don't take it for granted that the old rules and regulations are the magic weapon to solve the problem. If so, it would be a joke.
