"What this king wants to teach you today is the law of multiplication, one by one to get one, one to two to get two, everyone to follow along."

In recent days, Li Kuan has gone to work as a teacher at Mutual Aid Primary School.

"Lord Wang, please stay, student Dongfang Ping, I have a question to ask."

Dongfang Ping ignored Xue Li and Xi Junmai's guarded eyes, and ran in front of Li Kuan.

"Dongfang Ping? New to the master? Li Kuan looked at this scholar with a face and showed a smile that met the expectations of society.

"Yes, I joined the Mutual Aid Primary School ten days ago, and I was recruited by Chu Zhubo at that time." Dongfang Ping explained simply.

During this time, Li Kuan encouraged all the people and helpers in his workshop to go to the mutual aid primary school at night, and if the class was not enough, he arranged for the master to go to the workshop to take classes, anyway, the whale oil candle was produced by himself, and there was no shortage!

For older helpers, this request did not have much repercussions, but for those youngsters, the appeal was unprecedented.

Of course, the attraction is mainly due to the fact that Li Kuan has made each workshop formulate a policy that literacy to a certain level can increase the wages of the first level.

In this way, there are a lot of requirements for the number of masters, and Dongfang Ping and they joined the Mutual Aid Primary School in this context.

"What questions do you have?"

Looking at "Basic Mathematics" in Dongfang Ping's hand, Li Kuan's eyes lit up.

This book was written by Li Kuan himself, and the content in it did not have much novelty, that is, the level of the first and second grades of primary school, but it was the first time that Arabic numerals were introduced, and it was also sold in the Xinhua Bookstore in Chang'an City, but unfortunately it was said that the sales were dismal.

Unexpectedly, I saw it in Dongfang Ping's hands.

You must know that even in the Mutual Aid Primary School, Li Kuan is ready to wait for the students to master some basic mathematical knowledge before teaching Arabic numerals.

"Lord Wang, the students think that the arithmetic in this book is in line with the thing called Arabic numerals, which is very useful for learning arithmetic, but I haven't seen anyone teaching it in the Mutual Aid Primary School, and I want to ask the prince, can students teach it in arithmetic class?"

Li Kuan's eyes lit up, but he didn't expect to meet a literate person, "There is a night school, the initial purpose is to teach them literacy, and this arithmetic can be taught after a while." However, in elementary school, if you have a literacy of more than 1,000 words, you can teach it. ”

Dongfang Ping is willing to take the initiative to promote Arabic numerals, and Li Kuan will naturally not object.

Before, I just thought that Chu Suiliang and they were basically not interested in arithmetic, and most of the students had not even completed the literacy step, so Li Kuan did not teach.

"Lord Wang, the student still wants to ask a question, with "Basic Mathematics", is there a more advanced one?" Dongfang Ping looked at Li Kuan expectantly.

"Naturally, there is, but this king doesn't have time to write it now, what, are you interested?"

"This ...... Can students? ”

Dongfang Ping's face flushed with excitement.

"If you have any ideas, you can sort them out and show them to this king first."

Li Kuan didn't know what Dongfang Ping's level was, so he could only take a look first.

"Don't worry, the students will go and start sorting out immediately."

……

At Wendeng Wharf, two strangely shaped boats came, and a group of specially dressed people got off the boats.

"Inu-kun, this is Wendeng Wharf, the last time we landed from here, the wharf was deserted, there were almost no people, and now I almost can't recognize it."

"I heard that His Royal Highness the King of Chu has been in Liangzhou City for more than half a year, and Liangzhou has changed from a military town on the northwest border to a prosperous state capital; Now that His Royal Highness King Chu has been in Dengzhou for almost a year, it is normal that this place has changed a lot. ”

Although Li Kuan has never been waiting to see the dog on the mountain, this widow always goes to the Chu Palace's mansion to give gifts during the New Year's holidays, regardless of whether Li Kuan is there or not.

It's really a bit of a spirit like "King Chu abused me thousands of times, and I treated King Chu like my first love".

Wendeng Wharf currently does not have a special management personnel, after the dog and his party went to the wharf, they found someone to ask Li Kuan's residence, and left the wharf under the watchful eyes of a group of people.

"Lord Wang, a group of people came to the door, saying that it was an old man who came to visit."

The weather has been a little hot these days, Li Kuan hid in the backyard of the county government to listen to Zixia play the piano and drink iced sour plum soup, but he didn't expect an old man to visit.

"The deceased?" Li Kuan couldn't guess who it would be for a while, "Please let them in, this king will go to the lobby now." ”

"The subordinate dog has seen His Royal Highness the King of Tang Chu in Yamada, and I haven't seen him for a year, and the prince's demeanor is still the same."

As soon as the dog saw Li Kuan come out, he immediately had a smile on his face.

"Puppies? It turned out to be you. You didn't stay in Chang'an, why did you come to Dengzhou? ”

Li Kuan was a little surprised to see that it was actually the Tang envoy from the Wa Kingdom in front of him.

"Lord Wang, it has been two years since the ministers came to Datang, so I want to go back and report to the lord of the country about the harvest of this trip. Thinking that the prince has always taken good care of his subordinates, he deliberately got off the boat to visit the prince. ”

Hearing what Inoumi Yamada said, Li Kuan understood what the situation was.

Feelings: These Japanese people have learned something in Datang, and they are ready to go back to ask their masters for credit.

Historically, the envoys sent by the Japanese State to the Tang Dynasty have been reused after returning to China, and it is no wonder that the dog wants to go back.

"I don't know when I will see each other again. Little dog, you will be in Dengzhou for a while, so that the king can do his best to be a landlord. ”

Li Kuan suddenly thought that these Japanese people didn't know what they brought back when they returned to China.

According to his previous thoughts, except for the Buddhist classics and the Four Books and Five Classics, which they can carry, other things can be brought without them, especially books related to arithmetic, agriculture, iron smelting, etc., Li Kuan does not want them to take any of them.

As for them to write it down silently after they go back with their own understanding, that's another matter.

I have to make it a little more difficult for them, besides, the Tang envoy usually doesn't have the opportunity to get a professor in this area, and he may not be able to write anything if he wants to write silently.

Now that Inoue Yamada has sent it to the door himself, Li Kuan naturally has to check what they brought on the ship.

However, people are ministers of a country, and their own methods are not too barbaric.

"Thank you, my lord, my subordinates have this intention."

In the past year, whether it is salted fish or whales in Chang'an City, many things have come from Dengzhou; So they also have the heart to see if they can have other gains in Dengzhou.

In particular, the refined salt behind the Dengzhou salted fish, the dog is salivating, and he wants to figure out how to make it.

In this way, the two people with their own ghosts immediately reached an agreement with a smile.

It's just that who has the last laugh in the end depends on whose means are more clever.
