Modern Translation of the Ancient Joke "Looking at Monuments with Myopia"

Two nearsighted people read a story about a plaque. Two of them were nearsighted, and everyone refused to accept each other, so they decided to look at the plaque. On the first day they went, one of them asked someone what was written on the plaque. This man said that what he wrote was "aboveboard". The next day, someone asked them what was written on the plaque, and they said it was "aboveboard". Everyone laughed when they heard it. They said the plaque was not hung. How do you know this is aboveboard? When the plaque is not hung, everyone touches it with their hands. Later, a notary was invited to criticize, and they each stated their own experiences. The notary couldn't help laughing, because the plaque hasn't been hung up yet, and it's all "empty talk"!
