What does a blind eye tell us?

Blind eyes tell us that to see the whole picture of things, we should not blindly believe and worship them, but must go through scientific investigation and verification and treat them with modesty and prudence.

Blindness is an idiom in China, pronounced as YYYYZhà ng Mù, which means that a leaf in front of you will make you unable to see the outside world. Metaphor is confused by local or temporary phenomena.

"Laughing Forest" Three Kingdoms Han Wei Dan Chun

When Chu was poor, he read Huai Nan Zi and learned that "mantis can hide from cicada", so he picked leaves under the tree-mantis held the leaves and waited for cicada to pick them. Leaves fall under the tree, and leaves fall under the tree first, which can't be separated.

Sweep, fight and come back-one leaves the fence and asks his wife, "Have you seen me?" My wife always answers "yes" at first, but after a long time, she gets tired and disappears. Well, I was overjoyed, though. Ye enters the market and picks people up from the opposite side. Officials then bound Yixian. The magistrate was resigned and told the story, but the official just laughed!

Translation:

There was a man in the state of Chu. His family was very poor and penniless. He read Huainanzi, and saw a record in the book that mantis used leaves to cover his body when catching cicadas, so that other small insects could not see it, and he could use it to hide his body (if anyone could get the leaves).

He was very happy, so he ran to a tree and looked up, hoping to find the leaf that mantis used to cover himself when catching cicadas. I found it by accident, so I reached out and took it off. Unexpectedly, the leaves accidentally fell to the ground. There are fallen leaves under the tree, which are beyond recognition. So he simply swept up all the fallen leaves and picked up a few buckets to go home. ?

After taking it home, he took turns covering his eyes with leaves one by one and asked his wife, "Can you still see me?" At first, my wife kept saying, "I can see." Later, after a whole day's tossing, his wife was so tired that she lied to him and said, "I can't see!" " "Hearing this, the man secretly rejoiced, hurriedly held the picked leaves in his arms and ran into the street.

In the downtown area, he held up leaves and threw other people's things at his face, and no one looked. The government caught him red-handed and escorted him to the county government. When the county magistrate questioned him, he honestly described the whole story. The magistrate laughed without punishment and let him go.
