The eyes are blocked by a leaf, which means that you can't see the whole picture of things. There was a man in the state of Chu whose family was very poor. He read Huainanzi and learned that when mantis catches cicada, masked leaves can be used to hide people, so he really went to look for it. He ran to a tree and looked up. He found a leaf hiding mantis, so he reached out and picked it. Unexpectedly, the leaves fell to the ground and mixed with many fallen leaves, which was beyond recognition. So he simply swept up all the fallen leaves and collected several buckets. After taking it home, he covered his eyes one by one in turn and asked his wife, "Can you still see me?" At first, my wife kept saying, "I can see." Later, because of tossing all day, his wife was tired and impatient, so she coaxed 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 magistrate interrogated in class, the Chu people told the story from beginning to end. The county magistrate smiled and let him go without prosecution. You can't see similar words, but you can only adopt them when you see Mount Tai.
