Who is the big fool in the story of Carving a Boat for a Fish?

It should be "carving a boat for a sword", and the fool is a Truman.

During the Warring States Period, a Chu man crossed the river by boat. When the boat reached the middle of the river, he accidentally dropped a sword he was carrying into the river. He hurried to catch it, it was too late.

The people on board felt very sorry for this, but the Chu people seemed to have planned it long ago. He immediately took out a knife, carved a mark on the side of the ship, and said to everyone, this is where my sword fell into the water, so I want to carve a mark.

Everyone didn't understand why he did it, and they stopped asking him.

After the ship landed, the Chu people immediately launched in the marked place on the ship to catch the fallen sword. After fishing for a long time, there was no sign of the sword. He felt very strange and said to himself, didn't I drop my sword here? I also carved a mark here. How can you not find it?

At this time, the people on the boat said with a smile, the boat has been moving, but your sword has sunk to the bottom. How can you find your sword?

In fact, after the sword fell into the river, the ship continued to drive, but the sword would not move again. It's ridiculous to find a sword like him.

The moral of this story:

This idiom has two meanings. One is that if people's ideological understanding does not conform to the objective reality, they will not succeed in doing things.

On the other hand, objective reality is constantly developing and changing. If we regard the old rules and regulations as a magic weapon to solve new problems, we should also make jokes.

The author's thoughts are simple materialism and dialectics.
