Northern Dynasties Imperial Industry

Li Tai had no specific purpose for coming to the academy today. He looked aggrieved when he saw Liu Ang again, and felt a little guilty in his heart.

Liu Min had entrusted his son to him before, but he was busy with official duties and had been tending to Shang Yuan Village and neglected to pay attention. Now faced with Liu Ang's small request, he couldn't bear to refuse and nodded in agreement.

When Liu Ang saw that Li Tai agreed, he cheered happily, then took Li Tai's wrist and happily went to the Mongolian School. It was only after walking a long distance that he slowed down and muttered in a low voice: "I seem to have forgotten something..."

Li Tai also looked back and saw the forgotten "thing" following not far behind them, with a dull expression on his face.

At this moment, Liu Ang also remembered his mission, and quickly let go of Li Tai's hand and walked towards Yang Jian. After a short apology, he said: "Students in the academy call each other by their names or in small characters, or by their family rank. My name is Liu Ang, you can introduce yourself as you like."

Li Tai knew that Yang Jian was taciturn, so he answered on his behalf: "His name is Yang Jian, you can also call him Yang Da."

However, as soon as he finished speaking, Yang Jian frowned and corrected him: "Call me Na Luo Yan!"

Naluoyan means Buddhist Vajra Warrior. It can be seen that Yang Jian is very satisfied with this small word and is willing to be called this. Under the dull appearance, there is actually a burning soul of Chuni.

In the school, a group of schoolchildren sat in a circle, with two seats surrounded by them. A child sitting at each of the two seats was writing something down at his desk, while the children sitting around him were watching them with interest. .

"These two people were dissatisfied with the lessons taught by my husband. They just said that they were too simple and not difficult. So my husband specially gave them a few arithmetic problems. As long as they could solve them, he would give them separate lessons."

Liu Angxing went to the window of the school, first looked inside, and then said to Li Tai with a showy smile: "They are all old arithmetic questions that they have learned at Zhuang before, but they haven't learned them yet. The solution is very difficult. I was already working on it when I left, but I haven't finished it yet. If it were me, it would only take half an hour."

Li Tai stood outside the window and looked in, and found a question written on the hanging blackboard: Someone has stolen a horse and has gone 37 miles. The horse owner is aware that the horse has been chased for 145 miles and is still 23 miles away. How many miles will it take to catch up?

This question is a question in "Zhang Qiu Jian Suan Jing". Zhang Qiu Jian was a member of the Zhang clan in Qinghe, Hebei Province during the Northern Wei Dynasty. Li Tai's family also lived in Qinghe County in the past, so he incorporated "Zhang Qiu Jian Suan Sutra" into his family study. It is used by middle school students to enlighten their children.

This is a typical proportion problem. After chasing 145 miles, there is still a difference of 23 miles, which means that within 145 miles, the pursuit is close to 37-23=14 miles, 14:145=23:X. Although it sounds simple, it is still difficult for seven or eight-year-old children who have never been exposed to such problems and do not have this kind of arithmetic logic.

"I figured it out, I figured it out! It's just that the numbers are a little bit broken..."

At this moment, the children in the seats on the left side of the hall suddenly raised their hands and cheered.

Li Tai looked around and was immediately happy. It turned out that this boy was Su Wei, Su Chuo's son. The last time we met was at Su Chuo's funeral. This boy was young but very sad, which made Li Tai a little worried. Now he has been discharged and is much older than then. He looks very smart. healthy.

Li Tai didn't explain this specifically, but he didn't want Su Wei to be sent to his own school by his family. It's normal when you think about it. The elementary students enrolled in the school are children who are in the period of enlightenment.

At this age, the talents and talents have not been fully revealed. The so-called merit-based admission is just empty talk, and the only ones that can be recruited are the children of relatives and friends. If you don't know someone well, I'm afraid you won't trust your child to him.

Su Chuonai was Li Tai's recommender. Although Li Tai is no longer here, this friendship still remains. Now that Longyuan Academy has a strong reputation, it is natural for its clan members to entrust Suwei here.

"I solved it too!"

Following Suwei, another child raised his hand and answered. Li Tai also knew this boy. He was Gao Jiong, the son of Gao Bin, who had visited the mansion with his father before. Gao Bin is now serving as the governor of Xihe County, and Li Tai is considered half of his lord, so there is nothing wrong with entrusting his son here.

After seeing these two boys, Li Tai turned to look at Yang Jian aside, and saw that this boy was also staring at the blackboard, muttering something in his mouth, thinking he was also calculating the questions silently, but he couldn't figure it out, and he didn't do it at all. What clues to solve the problem.

When the teachers in the school heard that the two men had solved the problems one after another, they were quite surprised for a moment. They stepped forward to check and found that the answers were correct, so they also smiled and praised them.

Seeing this, the other students in the classroom burst into applause. At this moment, Su Wei and Gao Jiong were able to question their husband and solve the problem beyond the scope. In their eyes, they were absolutely heroic. Amid the cheers and cheers of their classmates, the two of them were as proud as victorious little cocks, with their chins raised high, enjoying this small highlight of their lives.

"We want to learn the essence of Governor Li's strategy and the secrets of invincible military tactics. Sir, please stop using these calculations about how to pay for catching thieves!"

After solving the problem given by their husband, the two boys became very ambitious. They looked at their husband and loudly put forward their requests.

When Mr. Xuetang heard this, he didn't know whether to laugh or cry. Why do you think I am here to teach you little guys? If I understand the gist of Li Dadu's military tactics and strategies, how about I lead the troops and become the Dadu myself?

Although there is no invincible secret art of war, this gentleman still has some methods to deal with naughty children.

He took down the blackboard and replaced it with another one. He pointed at the new problems on it and said with a smile to the students: "How can we teach the Dharma lightly? You wait for the young disciples to be complacent after they can only solve simple arithmetic problems. If you are more advanced, you will be at a loss. If you can solve this problem, you will be qualified to get a glimpse of it. "

Su Wei and Gao Jiong were so arrogant at the moment, how could they be afraid of new challenges? They were ready to let their husband see their superb IQ and skills again: "Today, a rooster is worth five, and a hen is worth five." One chicken is worth three, and three chicks are worth one. If you buy a hundred chickens for a hundred dollars, how much are the roosters, hens, and chicks?"

The other students in the school were also envious of Su Wei and Gao Jiong, and were eager to try out the new questions. But when they saw this question, they were a little dumbfounded. At first, I thought it should be a very simple question, but if I thought about it more carefully, I found that my mind was a mess and there was no clue at all.

Li Tai outside the door couldn't help but feel happy when he saw this problem. The Hundred Chicken Problem is the most important and typical problem in "Zhang Qiu Jian Suan Jing". It is a three-dimensional indefinite equation problem. Its problem-solving ideas have long gone beyond the scope of elementary education, and even many mathematicians in ancient times were unable to give a clear, easy-to-understand problem-solving idea. Now in this elementary school, it is this gentleman who is making things difficult for all the students.

Some students quickly gave up wisely after realizing that it was difficult to solve this problem with their own intelligence and knowledge. When they saw Gao Jun and Su Wei scratching their heads and frowning, they no longer struggled with this problem. , turned his attention to other places, and soon made a surprising discovery.

"That, that's Governor Li!"

Soon someone saw Li Tai standing outside the school. After a brief recognition, they shouted out in surprise. Others followed suit and were also pleasantly surprised. However, because they did not get permission from the teacher in the school, although they were overjoyed, they just stayed in their places and whispered to each other, not daring to leave the table and run out.

The school teacher also noticed Li Tai, stood up and bowed slightly to greet him. He looked back at the expectant eyes of the students, and then he smiled and announced that get out of class would be over for the time being, allowing these students to take advantage of the break to admire their idol.

At this time, all the students also poured out of the classroom, eager to come forward to express their closeness and admiration, but they were timid and held back.

At this moment, Liu Ang walked up to Li Tai and said proudly to his classmates: "I said before that I have lived with Governor Li for many years, but you still refused to believe it. Today I have brought Governor Li here, and you can do it yourself Asked a question!"

Li Tai also gave Liu Ang a face-saving smile and said, "Yes, if you have any questions, please feel free to ask."

"I would like to ask Governor Li why he chose Shouyang in Huainan to fight with Murong Shaozong in the middle of the year?"

Gao Jiong, who was still at his desk solving problems before, had already squeezed in front of his classmates. After hearing this, he was the first to raise his hand and ask questions. The other students are not far behind. They each come from a family of officials, so they are all familiar with current political information. In particular, they have heard a lot about Li Tai, who has been in the limelight this year, and have taken the initiative to inquire about it. Naturally, they are interested in meeting their idol. I want to ask all kinds of questions.

"Why don't you ask me if it's true that I lived in Governor Li's house?"

Seeing that his classmates were asking questions, but none of them asked about their previous doubts about him, Liu Ang immediately reminded him loudly with some grievances, but was soon drowned out by all kinds of noise, and no one paid any attention to him. This poor boy doesn't know the dangers of the world, so who cares how many bowls of noodles Liu Zi has eaten?

Because the students were too enthusiastic and asked too many questions, Li Tai simply spent a class time to satisfy the curiosity of these students and answered a few questions one by one that everyone was focused on.

The small commotion here also attracted the attention of the students in other classrooms. Dugushan, Cui Hongdu and other teenagers who were older than each other also came after hearing the news. When they saw Li Tai, they were also overjoyed and came forward. Each came to show their hospitality and show off their close relationship with Governor Li in front of the schoolchildren.

For example, this kid, Dugu Shan, stuffed his sister into his sister's wedding dowry last year because of his nonsense. His father beat him up and taught him a lesson. From then on, when he saw Li Tai, he became angry and angry, but now But every word called "brother-in-law" is extremely cordial. When Li Tai was sitting on the teacher's chair in the school, he was running back and forth in the school with a ruler in his hand to maintain order, just like a weakling who pretended to be powerful.

Dozens of students from three classes in the elementary school were attracted here, filling the classroom to capacity. Students from other schools also came after hearing the news, making the classroom even more crowded. Dugushan and several other older Meng boys were responsible for driving these outside students away and not allowing them to come and join the class.

Although those students were older and more powerful, they did not dare to argue and act recklessly in front of Governor Li, so they could only bow and leave.

But there were some who were not so obedient. Yu Wenyu, who was studying at the Confucian Classics School, also came here after hearing the news and wanted to talk to Li Tai. When he saw Dugu Shan rushing people here, he smiled and said: "Fu Tuo , Don’t you recognize me? Are you going to kick me out too?”

The engagement between Yu Wenyu and Dugu Xin's two daughters has been concluded, and the wedding ceremony has already begun. The wedding will be completed next spring. Therefore, he has often visited Dugu Xin's house recently, and naturally he has become familiar with these brothers-in-law.

Hearing this, Dugu Shan looked troubled. After thinking for a moment, he raised the ruler in his hand and said, "Ningdu Gong, I'm sorry. Although I recognize you, I don't recognize the ruler in my hand! My brother-in-law is a man of strict rules. Today Come in and teach Meng Tong, I can’t let irrelevant people harass my brother-in-law! Come on, hurry up!”

Yu Wenyu was forced to withdraw, feeling quite aggrieved. The man in the room is your brother-in-law, am I not the one?

After forcing all the people outside the Mongolian School back, Dugu Shan and others returned individually, standing next to Li Tai like loyal guards. After being glared at, they walked off the podium and stood in a corner of the room. Li curled up and squatted down.

While Li Tai casually answered the students' questions, he looked through the name list of the children of the Mongolian School. It didn't matter when he looked through it, but he actually became nervous. Except for Gao Jong and Su Wei, Zheng Daoyong's son Zheng Yi, Cui Xuanyou's son Cui Zhongfang, etc. are all among them.

He lowered his eyes again and looked at Yang Jian, who had already entered the classroom and was sitting in his seat. His upper body had grown more conspicuous. Everyone from the founding emperor to the founding heroes of the Sui Dynasty were gathered here!

When I think about the fact that my Lu Zhuang ambition has not yet been achieved, this group of little bastards who are waiting for the top have already completed their historic gathering. Don't let yourself become a tiger and end up making wedding clothes for others!

But at the moment, these boys naturally don't know what they represent. They all raised their faces and listened intently to Li Tai's summary of this year's series of wars, with expressions full of admiration and yearning. Yang Jian, the first generation leader of the Sui Dynasty, was a bit unsociable. He frowned and shook his arms in an attempt to drive away a few schoolchildren who were very close to him. He seemed a little irritable because he was not used to such a crowded and noisy environment.

The class ended quickly. When Li Tai stood up, the students, although they were still unfinished, respectfully said goodbye and followed Li Tai away.
