That pretty lady was not crazy, Song Jiu was about to go crazy.

Three days later, in the midst of great anticipation, two doctors arrived. They were not teachers in private schools, but also taught by the official teachers. They were powerful children of the Imperial College, and the doctors themselves were officials of the eighties and nine ranks. They represented the teachers of the most orthodox educational institutions of the Song Dynasty.

He came to the Song family almost in the middle of the road.

Only Song Jiu was uneasy.

really.

Song Jiu knew how terrible it was to read a book to death, so he was quite lively, and he was only nineteen years old and Zhu Santia twenty-one, and the oldest student was twenty-three years old. He had to listen carefully during the lecture, otherwise Song Jiu would scold him, but he laughed and laughed after class and encouraged them to ask questions boldly when they encounter something they don’t understand. Don’t learn much knowledge, including accounting and material learning. Just understand some of the superficial knowledge, but you have to understand it after learning the superficiality and you have to know it. This is Song Jiu’s requirement.

The two doctors couldn't stand it, and they were still in the future, so they first tampered in the living room. The main hall was covered behind the door of the authentic scholar and doctor's house, and the main hall was turned around. However, Song Jiu's father Song De was promoted to the position of war in the Later Zhou Dynasty. There was not so much attention. The main door was connected to the living room, and the main door of the living room was the main door. Behind the door was a yard, behind the yard were several main rooms, and behind it was the real garden, a small garden, but Song Jiu was too lazy to take care of it, now there were chaotic weeds, and then there was a place where women lived. The main rooms were all converted into classrooms, but the houses next to the main rooms were used to store miscellaneous items and cook, which were connected to the living room.

First, the utility room was formally separated from the kitchen room and the main hall. It didn't matter. Song Jiu had a meal alone. Now Zhu San got in, so the two of them had dinner. He was four brothers and sisters. The one who cooked the best was not the eldest sister, but Song Jiu. Song Jiu was a hiker and a foodie in his previous life. He was knowledgeable and could make some dishes that were not in this world, but his proficiency was slightly inferior to that of the eldest sister. But he was a man and was too lazy to cook. Sometimes he went to the eldest sister to eat, and sometimes he bought some snacks and made it easy. Zhu San came, and it was two people, so Zhu San took the mess, Song Jiu made dishes, and the two bachelors worked together to manage the meal. It was only two of them, so they made a small table in the kitchen, and then prepared it in the kitchen. After eating, Zhu San washed the pot and washed the dishes. It was useless to keep the passage door.

The only thing that changed was the bedroom. It was moved from the main room to the back room. It was not a long time since there was anyone living there. It was the eldest sister and the seventh sister who came to clean it. After a whole day, they cleaned the several houses in the back. Song Jiu's bedroom was moved from his original bedroom to his original sister's bedroom. In this way, the four front rooms were just used to be converted into two large classrooms.

It doesn’t matter, but when the two doctors come in front, they hang many letters on the walls on both sides of the living room.

All are quotations excerpted from the Book of Rites.

If you plan to the elders, you must carry a few sticks to follow them. If the elders ask questions, they will not refuse to give in and respond, which is inappropriate.

When discussing with elders, you must bring a scepter to you. If the elder asks, it is wrong to answer without giving in.

When you see your father’s friends, you must not get close if you don’t let them get close if you don’t let them go, you must not get back if you don’t let them go back if you don’t let them ask questions. And Song Jiu encouraged the students to dare to ask questions!

Quli mainly talks about what kind of etiquette is used to treat teachers, elders, kings, parents, elders, colleagues, wives, concubines, neighbors and young people from food, drink, wear, housing, transportation, wedding, funerals, and worship. It is sour, smelly and long, with hundreds of rules for eight or nine thousand words.

These two doctors took out dozens of etiquette and laws to treat teachers and elders, and hung them on the walls on both sides. Fortunately, they did not reject the fifteen rules of the teacher, otherwise they would have to let the yamen runners take off even the fifteen rules of the teacher.

If you follow these rules, will there be such a lively atmosphere of studying?

Song Jiu watched the three yamen runners chanting quotes under the instructions of two doctors, and didn't know how to refute them. Xiaojiu, do you even respect Confucius? Song Jiu was unable to have an attack, and a second conflict followed. The two classrooms wanted to expand students, and the people in the river cheered and cheered. Song Jiu was also happy. He still liked doing some good things without harming his own interests. Moreover, the neighbors who benefited were neighbors.

The two doctors are obviously more popular than Song Jiu. They are doctors in the court, and Song Jiu is just a disciple. They cannot be compared with each other. They are of age, hairless and have no sense of work. They are nearly fifty years old. Whether in terms of age or manners, they are obviously a grand, elegant and knowledgeable person. I don’t know how many neighbors come to sign up with their children. Dr. Zhang and Dr. Yan twist their beards and ask. It is impossible to accept them one by one. They can only choose disciples. Those who do business at home are craftsmen, those who violate the law at home do not want to have women do prostitutes, those who kill pigs and dogs at home do not want to have disabled people, those who are disabled, those who are not good-looking, those who are not good-looking, those who are not handsome, such as those who are not dignified, disrespectful, and those who are too shabby in their clothes…

Yes, it’s just a discrimination, but it’s reasonable in this era. This is called selecting a real good family!

But what will those young men who failed to be elected think in their hearts? What do the neighbors think?

The two doctors had never considered it.

Song Jiu saw many young men crying and running away, unable to bear it, so he pulled them aside and talked about this question: "Please draw lots. Before Emperor Gaozu of Han became famous, he was just a scoundrel in the countryside. Zhou Chu was a bully before he learned well, Fan Kuai sold dog meat, and Liu Bei wore straw sandals."

"Jiulang, you are right, but have you ever wondered why the court repeatedly allocated funds to fund your bookstore? He also let me run back and forth every day to teach you?"

“Why?”

"These students are ready to use them."

"Dr. Yan, can you explain it clearly?" Song Jiu suddenly realized in his heart, and felt that Liu Yi had bad intentions this time, and he was either a traitor or a thief.

Dr. Yan shrugged and said, "Yes, I can't say that I can't help but choose disciples, but I have to be strict with myself. This is not to choose disciples for me, but to choose people from the court."

Song Jiu had no choice but to endure it.

When I started teaching, I was ready to come. I also used chalk during teaching. Soft pen calligraphy and hard pen calligraphy are completely different concepts. The two doctors wrote well in their brushes, and the chalk calligraphy was just the same, but they were written neatly. Obviously, they only came through after practicing at home.

But it made Song Jiu unbearable.

That's what the lecture is about!

Ancient Chinese arithmetic is very strange. To give a simple metaphor, there is a question in the Tang Dynasty Han Yan arithmetic. It is a question in the renting and tuning method. It is required to have two ends of two twelve feet and five inches per leap year. The number of twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve twelve

77×2.45, Song Jiu was teaching abacus oral and finals, not only adding or subtracting, but also multiplication and division. When he was teaching, he was gradually improving. Many people couldn't remember it, so he had to fumble and improve while teaching students. If he mastered the multiplication abacus oral and finals, the answer would be revealed. It was really not possible. It was a stupid method, and he could also calculate the answer. It was just the mathematical knowledge of the third and fourth grades of elementary school, and it was not a difficult problem.

In the Tang Dynasty, it would be sad. If you don’t have enough brains, using chips to make officials calculate for one or two hours. Han Yan came up with a good way to change the formula. The so-called placing the number of 7 and 7, reversing it in half, turning it into a formula is X×7×7÷10÷2. Without the decimal point and three-digit multiplication, it will come out soon. But if you change another question, for example, 74.492×2.951869, Han Yan will probably be sad. But is it difficult? It is the knowledge of the fourth grade of elementary school students, which is the arithmetic that a ten-year-old child can calculate in the later generations. In this era, countless people will be defeated.

However, it cannot be said that ancient Chinese mathematics was backward. Zu Chongzhi's pi changed to a college student in later generations, and asked him to verify that he could do it at six or seven digits after the decimal point. In mathematics in the Song Dynasty, there were high power and high order square opening, Tianyuan Technique, Dayan Technique, gap accumulation technique, and round technique.

In fact, this strange phenomenon is similar to Chinese painting and Chinese-style flower arrangement, which emphasizes the unity of man and nature, the beauty of artistic conception, the beauty of chaos, and the beauty of fuzzy.

This kind of chaotic beauty of seeing mountains is not mountains is undoubtedly elegant in art and music. In fact, in Song Jiu's eyes, Chinese painting is the most beautiful art. Western painting is just like Western flower arrangement. Although it is lively, it destroys the rhythm of beauty.

However, is it possible to use mathematics, physics and chemistry that requires rigorous data?

There is also traditional Chinese medicine, which cannot be said to be bad. Some of the knowledge in later generations has to make the world recognize its effect. However, can it be explained by using science to explain the properties of the five internal organs, meridians, meridians, yin and yang qi?

There are arithmetic books: Sun Tzu, Wu Cao, Jiu Chapter, Hai Island, Zhang Qiujian, Xia Houyang, Zhou Feng, Five Classics Arithmetics, Art of Approaching, Ancient Countries, Records of Relics, and Third-class Numbers. These books are arithmetic textbooks and are the contents of the Tang Dynasty exams.

But like Han Yan's arithmetic question, they all look at the math of mountains that is not the math of mountains. Song Jiu had learned some of them before, but Song Jiu would give up and use the primary school knowledge of later generations instead. If the junior high school has not been taught, and if they have been taught to junior high school, they will not need high school at least after several months. As long as they learn the math of junior high school and pass the exam, they are definitely a first-class arithmetic master in the Song Dynasty. If they know a little bit of accounting knowledge, they can make a fortune everywhere, unless they are like Song Jiuyi who wants to be a rich man.

The two doctors brought these old antique arithmetic textbooks and taught them in class.

Not only did they teach these old antiques, but they also taught the laws of the Song Dynasty.

People's energy is limited. Although Song Jiu has done five courses, each course is for practical purposes. Now, students are allowed to focus on learning the laws of the Song Dynasty. What should they do in the future? Will they be legal magistrates who hate thousands of people and scold them? Or can they become officials of the court in the future?

Song Jiu listened for a while and gave the two doctors face temporarily. He endured the get out of class and quietly shouted them aside and said, "Dr. Zhang, Dr. Yan, these students have no effect after learning the law. You should not teach those mathematics. It's really not possible. You can teach them a few more words."

Dr. Zhang said: "Jiulang, what do you mean? The law has no effect? ​​When the priest sees someone and is still waiting for the etiquette, you actually say that learning the law is useless!"

Dr. Yan's face became even more gloomy and said, "Jiulang, so, are you better than those great arithmetic sages in the past? Or are you, a foreigner, more sophisticated than Chinese knowledge?"

"What a foreigner, it is just a simplified code name for easy calculation."

"You think we don't know it is a foreign number!"

Arabic numerals were not created by the Arabs, but came from India. After the rise of the Great Food Festival, they took it over and slowly promoted it to all parts of the world. However, the Central Plains civilization was too developed, and it was easy to flow to the lower part, but it was not easy to flow backwards to the higher part. Therefore, it appeared in China very slowly. However, Song Jiu made it out, and there were some people in the capital who came to settle in the capital for various reasons. Zhao Kuangyi did not know 1234, and someone in the capital could recognize it.

As for the English letters being searched, Dr. Yan was a foreigner. The debate was fruitless. Not only that, they also made some noises in the classroom. These students were not children of a few years old, some of whom were sensible in their twenties. Song Jiu taught foreigner mathematics, and two doctors came to teach them that it was the court's meaning. Maybe in the future, the court would select some people from their group of students to use for what they used for. The two of them kept their mouths tight. Then Song Jiu was restrained everywhere behind!

There was a little noise in front of me, and countless aunts surrounded Song Jiu. Xiaojiu, you can’t disregard the elders. Xiaojiu, he is a doctor of the court, so he is better than you. Xiaojiu...

Even the two doctors mobilized students to sort out the small garden behind, and sometimes invited three or two friends to sit in the small pavilion of the small garden to eat flowers and chat, and they were having a lot of fun. If this continues, the whole thing would be to occupy the magpie's nest.
