fishing for the moon in the water-empty

fishing for the moon in the water. Metaphor is futile. A calm water surface is equivalent to a flat mirror. An object in a plane mirror is a virtual image, and the image is the same size as the object. The moon in the water we see is just a virtual image of the moon in a plane mirror. Therefore, it is impossible to catch the moon in the water.

Nothing: All hopes and efforts have come to nothing.

Example:

1. He himself knows that without a formal job, finding a suitable partner in Huangyuan is tantamount to fishing for the moon in the water.

2. The detectives stayed here for two whole days, but it was like fishing for the moon in the water, with no result.

According to the Law of Monks and Monks, Buddhas and monks said that in the past, there were 5 macaques in the city of Bolonai, a corpse country. One day, they played in the forest and came to a well. The macaques thought that there was a moon (shadow) in the well.

So he said to his companions: The moon died today and fell into the well, so we should take it out to avoid the darkness in the world. The monkeys didn't know how to start. The macaque thought there was a tree in the well, so he said, I catch the branch, you catch my tail, and you can get it out by spreading and turning. So the monkeys turned to catch each other, the weak branches of the tree broke, and the monkeys all fell into the well water.
