For the people of the Tang Dynasty, the threshold for reading was very high.

On the one hand, the prices of books and paper are very high, which is definitely not something ordinary people can afford.

Even if the Qin family’s papermaking workshop greatly reduces the cost of paper, the price of a book is not acceptable to ordinary people.

A book that costs two yuan a book at every turn is basically equivalent to a book worth several thousand yuan per book in later generations, or even tens of thousands of yuan per book.

Not to mention tens of thousands of yuan at the beginning of the 20th century, even if the currency depreciated a lot in 2021, this expensive price is not something that ordinary people can accept.

On the other hand, it is to read and recognize words, and a teacher needs to teach you.

Otherwise you won't even be able to read.

It will take several years for a child to go from not knowing big characters to knowing thousands of commonly used characters.

But now Li Chengqian said that he would hope to reach this level in a few months.

This statement is really hard to believe.

That's all, now Li Chengqian said that mathematics is difficult for ordinary scholars to understand, and even a child can easily master it.

How is this possible?

"Gao Ming, are you sure you are not talking about individual prodigy, but a common situation in elementary school?"

Li Shimin looked at Li Chengqian with suspicious eyes.

Obviously he is a little disagreeable with his boast.

"Your Majesty, I can testify that the Crown Prince's words are not exaggerated, but simply report the situation here.

If you have any questions, you can take a look at the math books we have for children, and then find a few children to take the exam for the teaching exam.”

At this time, Qin Xiedao had already received the news and came to Li Shimin.

When he first created these things, he expected that it would be today sooner or later, so he was not panicked at all.

"Okay, since you are so confident, I'll have a good experience."

Soon, Li Shimin came to the classroom under the leadership of Qin Xiedao.

However, he originally thought he could watch a joke and expose Qin Xiedao's lies in person.

As a result, the children's answers were beyond his expectations.

"Xiedao, are these children really just learning mathematics for less than a year?"

Li Shimin did not deliberately make things difficult for Qin Xiedao, and he chose children who looked older last year.

But according to his normal understanding, it is normal for these people to know some simple addition, subtraction, multiplication and division, but that kind of complex algorithm will be beyond his expectations.

"Your Majesty, I will give you a few examples and you can see the benefits of the word Zhenguan.

For example, if forty-three times one hundred and twenty-two is based on the traditional calculation method, it may take a lot of time to calculate it.

But here, after using the word Zhenguan, we calculate according to this method, and we only need a few breaths to get the answer."

Qin Xiedao said while demonstrating it on the blackboard.

Later, I gave a few more examples, which completely allowed Li Shimin to see the extraordinaryness of these things.

"Xiedao, please sort out these things and let the Ministry of Rites arrange personnel to come and communicate with you in detail.

From now on, all the teaching books you are using now will be added to the teaching books of all the primary and primary schools in the Tang Dynasty.”

After seeing the benefits of this thing, Li Shimin naturally would not miss it.

Although he has only been a year old, it is something Li Shimin has always been preparing to do to promote poor scholars to enter the officialdom and promote the academic development of poor scholars.

Loomingly, Li Shimin felt that the thing Qin Xiedao created was helpful to his idea.

...

Taking advantage of Li Shimin's appointment of the Qin family's primary school and primary school textbooks as all primary school and primary school textbooks in the Tang Dynasty, the Qin family's Sanlian Bookstore opened.

I don’t know whether it is to take advantage of the hot spots or to disgust Qufu Bookstore, but Sanlian Bookstore is open opposite Qufu Bookstore.

Of course, in addition to selling books such as "Three Character Classic" and "Mengtong Mathematical Science", there are also popular books such as "Romance of the Three Kingdoms".

As for the traditional Four Books and Five Classics, there are naturally many books.

There is no concept of copyright these days. As long as you want to print and you have the ability to print, you can print as you want.

The printing cost and paper cost of Sanlian Bookstore are lower than that of other bookstores, which directly leads to almost no book in the entire Sanlian Bookstore selling for more than the usual price.

Even the thickest "Romance of the Three Kingdoms" is only priced at 999 cents.

As for booklets like "The Analects of Confucius", I simply set a low price of 100 cents.

The price of one hundred cents is equivalent to that of several hundred in later generations.

From the perspective of later generations, it must be very expensive.

But from the Tang Dynasty's time point, the price of 100 cents is definitely a new low.

The most important thing is that other books such as "Shangshu" and "Spring and Autumn" are not sold for more than 500 cents.

In this way, even if the opening of Sanlian Bookstore is very low-key, it has brought a huge impact on Chang'an City.

For three consecutive days, there were crowds of people inside.

Some booksellers even buy books wholesale from Sanlian Bookstore, and then take advantage of the opportunity that Sanlian Bookstore has not opened branches in other state capitals to transport these books to Luoyang and other places for sale.

With such a refusal, the profit margin is even as high as 100%, and it is still very marketable.

"Our house, our shop has not sold a single book in the past three days. If it continues to develop at this pace, our shop will be finished.

Qin Xiedao is really unruly, and this is not leaving us a way out."

Kong Zhiqiang just endured it for three days and could no longer bear it.

There is no way, even if he wants to be an ostrich, he can't do it.

"Have you figured out why Sanlian Bookstore's books are so low? Did you want to be sensational at the beginning or did they really have a lower cost?"

Kong Yingda was not a big deal in business.

But the current situation is really bad.

If I really don’t care, it would probably take less than two months for the Qufu Bookstore, which has a history of a century, to go bankrupt.

"I heard that their paper has a special method of making it, and the cost is very low.

That’s why books can be sold at such a low price. Of course, there is definitely a sensationalism, otherwise wouldn’t it be good to make money well?"

Although Kong Zhiqiang couldn't find anything to attract Sanlian Bookstore, he didn't do anything.

"If this is the case, then let our paper workshop find ways to reduce costs!"

Kong Yingda naturally said something.

This made Kong Zhiqiang want to cry very much.

If the cost of papermaking is so easy, it will be reduced so early.

"The boss, maybe... maybe not that optimistic..."
