Someone did an experiment. They wrote a lot of notes and rubbed them into a ball, or folded several layers and then rubbed them into a ball. They carefully checked each paper ball to make sure that ordinary people couldn't recognize the words in the paper ball, and asked Tang Yu to put the paper ball in his ear before recognizing the words in the paper ball. I saw Tang Yu sitting firmly among these inquiring adults, unhurriedly identifying the words in the paper ball through his ears. Surprisingly, he even recognized the 20-word Tang poem "Will there be frost on the bright line at the foot of my bed?" Looking up, I found that it was moonlight and sinking back, and I suddenly remembered that home was "word for word." People can't help but believe this witnessed fact!
