The Fourth Prince saw Zhao Yao staring at a page of a book without turning it for a long time and asked, "What's wrong?"
"It seems like something is missing." Zhao Yao flipped through a few pages of the book, and it was the same. He picked up another book and opened it, and it was the same. Now that he thought about it, all the books he had read were like this, without punctuation, making him learn to break sentences himself. "This isn't right."
The Fourth Prince asked in confusion, "What's not right?"
Zhao Yao pointed to the content in the "Diary" and said, "There's no punctuation." In his dream, the books Zhao Yao read had punctuation. They used punctuation marks to break sentences; that would make reading very convenient. Oh, and there was also pinyin.
