"Miss Lin taught so fast, can they remember?" Yu Zimo knew that Lin Qiya was also kind to teach them literacy, but if they couldn't remember it so quickly, it was equivalent to teaching them in vain.

"What they can remember, my sister seems to have taught them a pinyin, and the words they don't know will be marked, so it's not easy to forget." Lin Wenwen briefly said what he knew, and he originally two knowledgeable people should not be interested in this pinyin.

However, he guessed wrong, and the two of them became curious when they heard the term "pinyin".

"Pinyin? What is that? Canghuachi asked directly.

"I don't know very well, Xiaocai, you can talk about it." Lin Qiwen really didn't know pinyin, but Xiaocai knew it, so he asked Xiaocai to explain it to the two.

"This is a way to help recognize words taught by the young lady, using some symbols to combine them according to a certain rule to become the pronunciation of a word, so as to help recognize words. For example, the word 'day' is replaced by the combination of 'tian', and all the words 'tian' can use this symbol, but if the intonation is different, it can be represented by this, which can represent the four different sounds of 'tian, tian, licking, and 掭'. Xiaocai took out the small book he carried with him from his body, and today's book is a copy of "Thousand Character Text" that he copied himself.

"Can I take a look at your little book?" Yu Zi silently saw the book that Xiaocai took out, and wanted to see the contents inside.

Xiaocai didn't understand why Yu Zimo wanted to read his little book, but since everyone had spoken, his book was not a valuable thing, so there was nothing that people couldn't read.

Yu Zimo took the small book, this book was bound by himself at first glance, and this paper was obviously the paper made by Lin Qiya's family, but the size of this paper should be cut from some obsolete paper.

One page is not big, and now with the pen power of Xiaocai, one page can write four words.

Turning the first page is the first sentence of "Thousand Character Text" "Heaven and Earth Xuanhuang", and the word with symbols is only the word "Xuan".

"Why is this the only word with a symbol?" Yu Zimo pointed to the word "Xuan" and asked.

"At that time, I couldn't remember what to read, so I marked it, but now I don't use it."

Yu Zimo flipped through the other pages and found that some words were marked and some were not.

"All words can be marked? That's right, that's what Miss said when she taught, and she also said that some words that don't have can also be marked with this, such as the local dialect we speak, Miss said that some words are not in the book, but you can use this to express it. Although Xiaocai didn't know what words were not in the book, what Lin Qiya said at the time made him feel a little incredible, so he remembered it.

Xiaocai couldn't understand this, but several people here could understand it, especially Canghuachi's eyes lit up.

What he is thinking about now is not the magic of this pinyin, but thinking about whether pinyin can be used to transmit documents if it can represent all the words, even if such a text is seen by the enemy, if you don't understand the combination and arrangement of this text, you don't know what is written in the document.

"Is this easy to learn?" Canghuachi asked Xiaocai.

"It's easy to learn, my sister can do it, Miss said this is what we use as beginners to learn." Xiaocai became more and more curious about the pinyin taught by Miss, as if these young masters didn't know what it was, could it be that Miss herself researched?

"It's studious...... Canghuachi wasn't happy when he heard it, but frowned, and then asked Xiaocai.

"Who else did you young lady teach this pinyin?"
