&Quot; many people would wonder why the notes in ancient books are written differently by everyone. Actually, it's not strange. The ancient people have always been very cautious about the words on paper. They would study them word by word before finally writing them down. In addition, the meaning of ancient words is different from the words we're learning now. This resulted in a sentence in ancient words having completely different meanings in the eyes of different people. Other than these, the ancients had another problem. The good thing was that they didn't have punctuation marks when they wrote. In other words, you didn't know where they really wanted to make a punctuation mark. Perhaps the place you thought was a punctuation mark wasn't a punctuation mark, so the notes in the ancient book were written by different people. You couldn't say that they were wrong, because that was their understanding and not the intention of the author. Maybe they were wrong. Perhaps he's right."
