The "Lie Zi Shuo Fu" of Zheng Yukou in the Warring States Period: "The death of the ax means that the neighbor's son walked into the house and stole the ax; the color of the ax was also stolen; Speech, I am an open-minded axe, action attitude, inaction, not a stolen axe. The Org valley comes from the opening of the knife, which is reflected in the attitude of its son's action, and there is no complex visit like the stolen axe. "

A long time ago, there was a countryman who lost his axe. He allegedly stole the neighbor's son, observing the way the man walked, like stealing an axe; the expression on the man's face, like stealing an axe, and listening to his words and actions were more like a man stealing an axe, There's no one who doesn't like stealing axes.

Later lost the axe, dug in the valley, dug out the axe, and then noticed the neighbor's son, I think the way he walked expressed his face, he talked about it, it was not like stealing the axe, Not like stealing an axe.

This is a metaphor for subjective bias and obstacles to understanding objective truth. Observing stereotypes of the world will inevitably distort the original objective things.
