What kind of jokes are circulating about "one leaf is blind"

There was a joke in ancient China. It is said that a Chu man saw a note in a book that "mantis catches cicada, yellowbird is behind", saying that mantis can't see yellowbird because he hides behind a leaf. The Chu people think that all this is the magical effect of this leaf. So he looks for this leaf every day. One day, he finally saw the interesting story of "mantis catches cicada, yellowbird is behind", and there is a leaf in front of yellowbird. He took the leaf home, held it in front of him and asked his wife, "Madam, have you seen me?" Of course, the wife could see it, so she said, "Yes, how could she not see it?" He didn't believe it, covered it and asked again. His wife was impatient. She said, "I can't see anything." The Chu people said happily, "This is the truth."

The next morning, he came to some stalls one by one, covered them with the leaves and got something to eat. Small stall owners think he is a fool and don't care about him. This made him think that the stall owner could not see him and jumped for joy. Later, I came to a cloth shop, carried a piece of cloth and left. The shopkeeper reached for him and said, "How can you take my cloth?" He was surprised and said, "What, you can see me?"

Of course it's a joke.
