Northern Dynasties Imperial Industry

"One is 1, two is 2, three is 3..."

In class, Li Tai took a small wooden stick and tapped the content on the blackboard: "In the front are the straight characters, and in the back are the casual numbers. The casual numbers are used for calculations. When entering the paper, the straight characters must be written!"

There were more than twenty people sitting in the classroom, old and young. There were schoolchildren who had received enlightenment and had excellent grades, and there were also old men who had a rough understanding of writing. There are also talents in management who have been selected in the past few months, and they are all seriously accepting the arithmetic enlightenment given to them by Master Lang.

The popularity of knowledge among the ancients was truly appallingly low.

Most of the dozen or so family members Li Tai brought from Dongzhou had received preliminary education because they had grown up with him since childhood. There are a few people who are smart by nature, such as Li Quji, whose academic quality is even higher than that of Li Tai, the master of the family.

However, among the new tribes of scholars in Kansai, there were very few literate people. Li Tai did not expect all of them to be able to read poetry and books, but as the family affairs became more and more complicated, these stewards should know at least mathematical operations and accounting.

Especially after Zhou Changming was appointed commander-in-chief, Li Tai seconded Li Quji and several other family members with both civil and military talents to help him organize the township league. There was an urgent need for talents to manage family affairs and they needed to be trained quickly.

The mathematical development of the ancients was not low. Not to mention Zu Chongzhi who had already calculated pi in the Southern Dynasties, the "Sustaining Classic" textbook circulated in the Northern Dynasties was actually not bad at all.

There are many application questions in "Suan Jing", and the types of questions are closely related to life.

Now if I owe him money, I will repay it with profit. At the beginning, the profit was doubled and the money was paid back one hundred. The second time, the profit was tripled, and the money was paid back 200. In the third round, the profit is quadrupled and the money is repaid three hundred. On the fourth transfer, the profit is five times, and the money is paid back four hundred. At the end of the day, all the multiples of the transferred profit are the capital. Now, excluding the initial capital, we have 5,950 money. How much is the initial capital?

Today there is a person with money, first one person with three qian, next person with four qian, next person with 5 qian, next person with 5 qian, and then transfer one more qian, and finally collect it and divide it equally, and the person gets 100 qian. Asking people about their geometry?

Li Tai seemed to be able to understand these questions, but if he did not calculate the equations carefully, it would be difficult to blurt out the answers. It is obviously inappropriate to use this as a teaching material to teach people who are illiterate.

What he wants is not high-end mathematical talents who can calculate pi, but at least the basic calculation problems of material increase and loss at home, so he can teach them simple and easy-to-calculate Arabic numerals and quickly master basic mathematical operations.

Of course, when actually entering paper and making accounts, you still have to use regular traditional Chinese numbers.

After finishing an introductory math class, Li Tai assigned a few more math problems as homework, and then went to another classroom door. Li Zhusheng, who was educating the children on literacy in the hall, asked the children to study on their own and walked out of the classroom.

"Has the engraving of the account book lines been completed?"

Travelers who go back to the era before the Tang Dynasty and do not engage in printing are firstly brainless and secondly heartless.

Li Tai did not get started with the academic printing of classics. He had made several editions of official documents and accounting forms before, and ordered the engravers to carve them out. The matter had been ordered for more than half a month, and today I thought about it and asked Just ask.

After hearing this, Li Zhusheng returned to his residence next to the school. Soon he took out a three-dimensional 16-karat wooden carving block and handed it to Li Tai: "The block has been finished, but the ink is still being mixed."

Li Tai took the engraving and put his palm on the convex pattern and pressed hard. He turned his hand over and saw that the indentation in his palm was still clear. He nodded with satisfaction: "After the ink is prepared properly, the printed matter will be brought as soon as possible." I read!"

With these printed fixed forms, the names of some commonly used materials are stamped with engravings. After that, the manor stewards only need to fill in the specific entry and exit figures, which naturally greatly increases the efficiency of accounting and makes it easier for Li Tai to check the accounts.

"It's a pity that Black Otter is too crazy and doesn't give me face. If I are given an official position, the administrative efficiency of the government can be improved for him and the cost will be reduced. He deserves to be unable to become the emperor when he grows old!"

Feeling that he was smart in what he did, Li Tai couldn't help but sigh.

Zhou Changming was promoted from a mere rural garrison commander to commander-in-chief. Although Li Tai was sincerely happy for him, he was also greatly affected.

It is human nature to hate others and blame others. He has been a time traveler for more than 30 chapters and is still just an idle worker in Gao Zhongmi Situ Mansion. This shows that Yu Wentai is a dim-witted person!

"Alang, someone outside the village sent me a message to visit. He named himself Shi Jing. I think he must be a relative of the Shi family."

Li Yan, who was in charge of the front hall, walked over with a broad head and said from a distance, waving two famous cards in his hand.

After hearing this, Li Tai couldn't help but be surprised: "Isn't Shi Jing locked up in a pig pen? Why did Shi Jing appear again?"

"It's not respectful, it's quiet!"

Li Yantou was also happy when he heard this. He came forward and handed the name card to Li Tai. Li Tai took a look and understood.

This Shi Jing's name comes from the surname of Chen Jingzhao and Du Ling, and he also has the title of General Weilie. Presumably, Hongo Shi Gong felt that he could not suppress Li Tai, so he asked the Jingzhao family to be a lobbyist.

In the late Northern Wei Dynasty, the number of generals with miscellaneous names was already rampant, and in the Western Wei Dynasty, this proliferation was even more serious. For example, when Zhou Changming was still serving as the garrison commander, he had the rank of seventh-rank general Dangnan. After he became the commander-in-chief, he was given the title of sixth-rank general Xuanwei.

As for what grade this mighty general is, Li Tai really doesn't know. Once the name becomes too common, it loses its solemnity. In short, in his opinion, as long as he is not the general of the Zhu Kingdom, everything else is almost meaningless.

Aside from the name card of Jingzhao Shi's family, another name card caught his attention. The owner of the famous post is named Lu Rou, who is from Fanyang. He is an official and a scholar in the province, and he actually has the title of Rongcheng County Son.

The official system of the Western Wei Dynasty inherited that of the Northern Wei Dynasty and included indiscriminate affairs. Li Tai did not know how powerful the Shusheren were, but the position of the Fanyang Lu family made him think twice. The reason why He Basheng was friendly to him was because his uncle Lu Shuhu was from the Fanyang Lu family.

"Is there a relative named Lu Rou in the family?"

Li Tai thought for a while, but couldn't remember whether he had such a relative, so he asked Li Yantou.

Li Yan scratched his head and laughed dryly: "Alang doesn't know yet, how could I know?"

"Forget it, go and call Uncle Zhu Sheng to the central hall."

No matter what kind of relative she was, this Lu Rou came with the Shi family and must have been a lobbyist. Li Taizheng planned to kill the historian severely, and no one could give him any face.

When Li Taixing reached the middle hall, he ordered his family to introduce the visitors. Not long after, a sturdy young man in his early twenties and a middle-aged man strode over.

"Jingzhao Shi Jing, I have met Li Lang. Li Lang..."

When the young man came close, he raised his arms and bowed. Before he finished speaking the polite words, the middle-aged man had already stepped forward, looked directly at Li Tai, and said with a trembling corner of his mouth: "You, you are... Is it Ah Pan? Back then, when I was traveling south, I once visited my hometown. Ah Pan, you were just a naughty kid playing in front of the court, but you don’t want to think that now, you are already..."

Li Tai was surprised when he saw this middle-aged man speechless with excitement. He originally thought that even if they were related, they were just honorable relatives who didn't often interact with each other, but he didn't expect that Lu Rou would be so excited when she saw him. .

Just when he felt a little embarrassed, Li Zhusheng had already walked over, pointed at Lu Rou from a distance and shouted: "Is it really Zigang, Lu Dalang?"

"Nagisa, Nagisa, it's me, it's me!"

When Lu Rou saw Li Zhusheng, her expression became even more excited. She strode forward to greet him, hugged Li Zhusheng's arm and patted him several times: "I didn't expect that we would meet again, but it would be in Kansai. Did you come with Apanxi? Is he okay? Are my aunt and uncle still in Qinghe?"

The two middle-aged men stood together with arms folded, each talking passionately about their feelings. As for Li Tai and the young man from the Jingzhao family, they were left alone and just looked at the two of them.

"Alang, Lu Da is the nephew of my mother-in-law..."

Li Zhusheng also guessed that Li Tai probably didn't know Lu Rou, and it took him a while to remember to introduce each other. It turned out that Li Tai's mother, Lu, was Lu Rou's cousin, and Lu Shuhu's blood sister. They were not considered cousins. Far.

"We met when we were young, my memory is blurry, and I neglected my cousin. It's really rude!"

When Li Tai saw that Li Zhusheng and Lu Rou were talking so much, it was inconvenient for him to be wary of alienation, so he came forward to greet them again.

"Ah, Ah Pan, what a handsome boy! He looks like your mother, not like you. When my aunt got married, the eldest brother in the household sighed, there is no need for a rich dowry, my aunt had already given me a rich dowry. The elegance of every door brings it to your home!”

Lu Rou was not only excited, but also stuttered a bit. She pulled Li Tai and looked up and down with emotion. Then she pointed at the increasingly embarrassed Shi Jing next to her and said, "Fortunately, Mr. Shi Lang visited Mr. Cui yesterday to ask for something. I just happened to be at my cousin's house, and I found out that you, Apan, had also come to Kansai! Since I was busy with my work, I had nothing to do, so I went to see you in the countryside together with Shi Langjun! "

Li Tai was a little curious when he heard this. Could it be that his family had relatives who were high officials in the Western Wei Dynasty?

"Thank you, Mr. Shi Lang. If it weren't for this, my cousin and I don't know when we would be able to see each other again."

Although his intention to kill the Shi family has not changed, he still has to take into account the politeness of face. Li Tai smiled and nodded to the young man Shi Jing.

Shi Jing hurriedly clasped his fists and said, "Li Lang's words are serious! Not long after Lang Jun arrived in the country, his voice has gradually spread. Even if I don't send the message, it will soon be known to everyone. On the contrary, I am full of shame in asking for an audience, so I beg you to be honest." Can you forgive the offence of the common people?"

"Yes, Apan, what is going on? I heard that not long after you entered the country, you had many conflicts with the people in the village. There are more rumors that you rely on the majesty of Grand Master Heba and are unwilling to be harmonious with the villagers. get along……"

When Lu Rou heard this, she also frowned, turned to look at Li Zhusheng and said: "Apan, he is still young, but Zhusheng, you shouldn't do it! Let's go westward for justice and live in Guanzhong, but we can't You have lost your integrity as a tutor and bullied the corporal!"

"So this is how Mr. Shi said his farewell to my cousin, so I need to explain it carefully! I am not afraid of the cunning people in the village who confuse right and wrong, but I don't want to be misunderstood by my old friends and that I have lost my upbringing!"

When Li Tai heard this, his face suddenly darkened, and his eyes looking at Shi Jing became sharp.
