After the Mid-Autumn Festival, Chao Yong went to Taixue and began to teach mathematics.

After Wang Anshi changed the law, he divided the students into three classes: the upper house, the inner house, and the outer house. 、

Outside the dormitory, the monthly assessment of "line" and "art". The so-called "line" mainly refers to the conduct of abiding by the law and discipline, and the "art" is the result of the monthly examination by the school officials, which can also be said to be the results of the school's internal examination. Each student's examination results are recorded as credits and are registered on a monthly basis along with their character performance. At the end of the quarter, students who have accumulated more credits and have not committed serious disciplinary violations can be qualified for "quarterly selection" (quarterly evaluation). At the end of the year, the 100 students with the most accumulated credits will be selected based on the quarterly selection of students, and they will be "proofread" (annual evaluation). Compared with the monthly examinations held by the school, the imperial court will also send officials to Taixue once a year to test the students outside the school, which is called the "public examination". Those who rank first or second in the public examination and are approved can be promoted to the inner house.

The students also assess the "line" and "art" every month, and conduct the "quarterly selection" every quarter, but the number of "proofreading" students is only 30 every year, which is divided into two categories: "excellent" and "average". The time of the "public examination" is once every two years, and the results are divided into three categories: "excellent", "average" and "no".

If the public examination is excellent, and the school is also excellent, you can be promoted to "upper class", and immediately release brown and confer officials, which is called "two excellent release brown"; If the results of the public examination are one excellent and one equal, they can be promoted to "upper house middle", continue to study, and when the imperial examination is held, they can directly participate in the palace examination without the need to solve the examination and the provincial examination; If the results of the public examination and the school are equal or one excellent and one is negative, you can be promoted to "upper and lower class", continue to study, and when the imperial examination is taken, you will only be exempted from the examination and participate in the provincial examination. If one is flat and one is not, it is obvious that you will not be able to rise to the top of the house.

Wang Anshi originally established the three-rounding method because he wanted to replace the imperial examination with the entrance examination. It is more prudent to select scholars based on the results of one imperial examination than to select scholars based on the results of one imperial examination. However, Wang Anshi did not promote it, but only implemented the three-rounding method in Taixue.

When Zhao Ji was in power, Zhao Ji really popularized the three-rounding method throughout the country, and once replaced the imperial examination system with the three-rounding method. But in the third year of Xuanhe, he gave up the whole world and resumed the imperial examination, and only Taixue could continue to use the three-way method. That's why people from all over the world gather in Tokyo.

There are also many shortcomings in the implementation of the three-round method, most of the students who are exempted from the entrance examination are the children of official eunuchs, and the school examination is also prone to cheating. There were also some excellent scholars who did not go to school, for the rulers. Wild and unspared is their goal. Although many sages entered the imperial court, they would also be driven out.

What you can't get is always the best.

Daliang also continued the imperial examination system of the Song Dynasty, and only Taixue could directly appoint officials and participate in the imperial examination through the three-round method.

However, there are only a handful of people who can directly go out through the three-round method, there are 2,000 students outside Taixue, and only 300 students in the inner house. A hundred people were born in the upper house.

And the two thousand four hundred were divided into eighty fasts, thirty men each. Each fasting has a fasting chief and a fasting oracle, all of which are served by students, in fact, they are modern class cadres.

Chao Yong made sufficient preparations for this lecture, not only reviewing the mathematics he wrote in advance, but also specially preparing teaching tools.

Taixue did not send too many teachers and students to greet the prince. It's just that the prefect of Taixue led a few officials to greet the prince at the door. This is also Chao Yong's request, for the smooth progress of the imperial examination, he ruthlessly dealt with Chen Dong, a student who led the trouble, and it can be imagined that most of the students of Taixue will not be too friendly to him. He also didn't want to mobilize the crowd and intensify the contradictions.

Accompanied by Senior Taixue, when Chao Yong came to a lobby, it was already full of students who volunteered to listen to the lecture. There were also some officials who rushed to the front when they heard the news, and they didn't know that they were here to study. I'm still here to flatter the prince. There were no seats, and the aisles were full of people, hundreds of people, and there were some people standing at the entrance of the lobby.

Chao Yong smiled at Senior Taixue: "Taixue students are easier to learn than I thought. ”

Senior Taixue secretly wiped a cold sweat and said, "The more students there are, the more difficult it is to teach, and there are always people who ask some specious questions. The prince should be prepared. ”

Chao Yong's reputation for being strict with literati had already spread throughout Liang Shilin, so the Taixue chief was also very troubled by the prince's decision to come to Taixue to give lectures, but he didn't dare to stop Chao Yong. And he was also aware of Chen Dong's reputation in Taixue, and when he saw the unkind eyes of many people around him, he knew that many of them must have wanted to avenge Chen Dong and deliberately came to make things difficult for the prince.

The prince's decisiveness in killing also made everyone dare not speak badly to the prince, but they could find the mistakes of the prince's teaching, so as to hit the prince.

Although this will not do any substantial harm to the prince, who is known for his force, if the prince is angry because of this, maybe he will be implicated. But he didn't know which students would attack, and he couldn't guard against it, so he could only remind the prince in advance to show that he was innocent.

Chao Yong was also a little mentally prepared for this, and said with a smile: "Sensitive and studious, not ashamed to ask, this is the attitude of learning." ”

Walking to the middle of the hall, Chao Yong stopped, and the soldiers behind him distributed the printed books to everyone in the hall, and a few soldiers carried the blackboard to the front.

"Jingle Bell"

After a crisp sound, the soldiers fixed a few iron nails on the wall, and then hung the blackboard on the wall, and after confirming the firmness of the blackboard, Shi Yong withdrew with the soldiers.

When the teachers and students of Taixue saw a jet-black wooden board hanging on the wall, they couldn't help frowning and thinking about the purpose of this blackboard.

In the puzzled eyes of everyone, Chao Yong walked to the blackboard, nodded to everyone, and said, "What I want to teach you today is mathematics, which has some similarities with arithmetic, but it is not the same. Which is better or worse, you slowly appreciate it. I'll start by teaching you numbers, which are the most basic things in mathematics. ”

Saying that, Chao Yong took out the chalk made by the craftsman, he didn't know that it was the same as the chalk of later generations, but the effect of using it was the same.

Seeing the white numbers appear on the blackboard, the people in the lobby also knew the purpose of the blackboard, and they couldn't help but let out exclamations.

I don't know if the math in the book in my hand is good or bad, but the blackboard and chalk are good things for teaching, with these two things, teaching will undoubtedly be more convenient, and it can lower the threshold for students. As long as the content of the professor is written on the blackboard, students who do not have books can also study. And compared to the teaching in the past. Writing what is taught on the board can also improve the level of teaching.

The learning ability of teachers and students in Taixue is much stronger than that of the palace maids and eunuchs in the Taixue, and Professor Chao Yong's progress is also much faster.

In fact, there is not much new in mathematics, and many rules have been summarized in arithmetic books throughout the ages.

At the end of the lesson, the teachers and students discovered that the prince had only introduced a new type of numbers and plus and minus symbols, and those who were well-informed recognized that these numbers were from the West. However, students and faculty have also found it easier to use these numbers and symbols.

Books are also a little different from the traditional ones, in that in the past, books were arranged vertically, but the books written by the prince were arranged horizontally and used some symbolic breaks.

Horizontal and vertical arrangements are just a matter of habit. The symbolic sentence break made everyone feel convenient. The most difficult thing for everyone to accept is that the language in the books is in the vernacular, which reminds them of those peddlers and pawns in the market.

When a scholar turned to the back and found that the whole book was written in vernacular, he got up and said, "The books in the market are all in the vernacular, but the whole book of the prince is in the vernacular of the market." Insulting to Sven, the students dared to ask the prince to rewrite the book. ”

A few scholars who were good with Chen Dong also immediately got up and agreed.

Chao Yong has been waiting for them to come out to find faults, but he didn't expect them to find such a thing, and said with a smile: "I don't read much, I can only read and write, but I can't write articles that you are good at." Mathematics is not only taught in schools all over the world. It should also be taught to the people of the market. Qu Gao and widow, educated and classless, you should think about it. If you want to listen, sit down and listen, and if you don't want to listen, turn around and go out. Rest assured, no one will take revenge on you for this. ”

A few people thought about it. Two people really walked out, and the rest of them didn't know whether they wanted to continue to find fault or listen, so they all sat down.

It's almost noon. Chao Yong ended the first day of teaching, at the warm invitation of the senior Taixue. I had lunch at Taixue, and I didn't continue to teach mathematics in the afternoon, but visited Taixue for half a day, and let the teachers and students digest what they had learned.

After teaching for several days, the number of teachers and students who attended the lecture did not decrease, but many teachers and students came to visit, and the hall was full of teachers and students listening to the lecture every day.

The blackboard, chalk, and blackboard erasers brought by Chao Yong were not only popularized in Taixue, but also spread to the world at a rapid speed.

Although mathematics was also praised by some scholars, not many people felt how important mathematics was, and in their opinion, mathematics was nothing more than the prince's transformation of arithmetic, far from being comparable to the learning founded by the sages.

On the third day of Chao Yong's lecture at Taixue, small blackboards and chalk began to be sold in the market. The materials of these chalks are different, but they can all be written in white letters.

Most of the buyers are scholars from ordinary families, for whom pen, ink and paper are not cheap, good steel should be used on the blade, their pen and ink paper can only be used for some formal homework, and a large number of contacts are usually completed with sand tables.

In fact, there is not much difference between the sand table and the blackboard, but the whole city is talking about the invention of the prince, and they will inevitably follow the trend. It's a small profit for the city's brainy vendors.

Shi Qian also reported to Chao Yong every day the evaluation of the city sergeants, and after learning that the status of mathematics was still far lower than those scriptures, he decided to throw out another science.

On this day, after Chao Yong finished teaching mathematics, he said to everyone: "I also wrote a book called physics, which aims to reveal the laws of all things in the world. In the afternoon, I will do some experiments at the Kaibao Temple Tower, and if you are interested, you can go with you. ”

After that, he announced the end of class.

Everyone got up to send off the prince, and Taixuexue, who was in his thirties, was following closely behind Chao Yong and coming to the Taixue canteen.

It is said that this Xuezheng is also a historical celebrity, he is the traitor Qin Hui who killed Yue Fei.

Qin Hui was also born in the Song Dynasty Jinshi, and began to teach Mizhou professors, and later won the word study and Mao Branch, and was awarded the Taixue Xuezheng. After this guy saw the prince coming to listen to the lecture, he tried his best to curry favor with Chao Yong.

Not only did he listen to the lecture carefully, but he also reviewed it carefully when he went back, and even drew inferences from one another, figured out the content behind, and seized the opportunity to ask Chao Yong for advice, showing that he was serious about the prince's teachings.

When Chao Yong first heard Qin Hui's name, he couldn't wait to smash Qin Hui to the ground with one punch, but when he saw Qin Hui's appearance of a decent man, he could only endure it. However, he also hated this traitor who killed Yue Fei, and when he went back that day, he asked Shi Qian to collect Qin Hui's past, wanting to see if Qin Hui had done anything wrong. He's so angry.

It's just that I didn't expect Qin Hui's history to be very clean, which may have something to do with Qin Hui's previous work in the school and no real power, in short, Chao Yong didn't find evidence of Qin Hui's crime. On the contrary, he collected some favorable evaluations for Qin Hui, and he was studious and diligent, otherwise he would not have won the award twice.

can't get evidence of Qin Hui's crimes, and Chao Yong can't punish Qin Hui, after all, he can't execute Qin Hui because of something that hasn't happened yet, and after the change of dynasty. Those things can't happen anymore.

Just as he reused Zhang Bangchang, Li Bangyan and others, these capitulation factions are often the best ones to use when there are no available people.

And I have to say that Qin Hui is very attentive to the study of mathematics, and Chao Yong noticed Qin Hui after that. It was decided to let Qin Hui spread mathematics on his behalf.

He won't continue to lecture in Taixue, as long as he finishes speaking, he will hand over the task of continuing to teach to Qin Hui. Qin Hui is too learned and learned, and he learns well, both in terms of identity and knowledge, he can complete this task perfectly.

Therefore, Chao Yong will also give Qin Hui some time in his spare time. And Qin Hui will also make full use of this time, and he will not waste a moment, even if there is no problem, he will create some problems.

It's only a few days. Qin Hui became the prince's loyal dog.

In order to facilitate the teachers and students of Taixue, Taixue also set up a canteen, and the imperial court also subsidized the students of Taixue, 1,000 Wen per month. The imperial court would also provide accommodation for poor students selected from other places.

It can be said that the imperial court provided a lot of convenient conditions for Taixue students. The purpose is that these students concentrate on their studies and serve the imperial court after completing their studies. These are basically the continuation of the Song Dynasty policies.

The food in Taixue's canteen is not inferior to some restaurants in the city. There are even some dishes that are famous all over the city.

The famous "Taixue steamed buns" are made by the Taixue canteen, and later received the praise of Song Renzong, and the reputation is far and wide, and the merchants in the city buy the practice at a high price, and still sell them in the name of Taixue steamed buns in the city.

The steamed buns at this time are actually the buns of later generations, and the cooking cakes sold by Wu Dalang are the modern steamed buns.

Taixue steamed buns are meat-filled buns, which are delicious. Once, Song Renzong Zhao Zhen came to Taixue to inspect, and what Taixue ate that day was steamed buns.

After Song Renzong ate the steamed buns, he immediately praised them: "It is worthy of raising a soldier with this!" ”

The emperor's Chrysostom Yuyan evaluation immediately spread Taixue steamed bread in Tokyo, attracting merchants to buy it, making Taixue steamed bread a famous snack in Tokyo.

After having lunch in the Taixue canteen and taking a short rest, Chao Yong came to Kaibao Temple surrounded by Taixue teachers and students.

Many people in the city saw the prince leading the teachers and students of Taixue to the street, and they also followed behind with curiosity, making more and more noise.

When I arrived at Kaibao Temple, there were already thousands of people behind, and I was so scared that the monks of Kaibao Temple were almost about to close their doors.

Chao Yong ignored the temple hosts who came to greet him, but led everyone to the temple tower.

The iron tower of Kaibao Temple is not really made of iron, but a brick tower, but because the glass on the surface is iron brown, it looks like an iron tower, so it is called an iron tower.

The tower is 180 feet high and has 13 floors, each of which is equilateral octagonal.

The Kaibao Temple Iron Tower is famous, not because the current glazed tower is famous, but because he has rich allusions. When the Kaibao Temple Tower was first built, it was not a glazed tower, but a wooden tower.

The original wooden tower of Kaibao Temple was supervised by Yu Hao, a famous craftsman of the Song Dynasty, octagonal thirteen layers, three hundred and sixty feet high, on the tower of a thousand Buddhas and ten thousand Bodhisattvas as the heavenly palace to serve the relics of the Buddha, it took eight years to complete the completion.

When the wooden tower was first completed, the officials and people in the city found that the wooden tower was not straight, but inclined to the northwest, Yu Hao was a famous master in the world, and naturally no one would suspect that he had not designed it. So he asked the reason curiously, and Yu Hao said: "There are no mountains in the capital of Beijing, and there are many northwest winds, and it will only blow for a hundred years." ”

This tower is extremely magnificent, the tallest among the towers in Tokyo, and the system is very sophisticated. The grandeur of its civil engineering and the brilliance of gold and gold are unprecedented, so it is praised as "the crown of the world".

It is a pity that this gorgeous wooden pagoda designed and built by Yu Hao only survived for 56 years, and was struck by lightning and burned down in June of the fourth year of Song Renzong's Qingli calendar.

At that time, the wooden tower had been blown by the northwest wind, and people all over the world were still curious about whether the wooden tower would tilt to the southeast if it continued to blow. Because Yu Hao is known as the "reincarnation of Luban", and also wrote three volumes of "The Book of Wood", which is an important architectural monograph of the Song Dynasty, people feel that Yu Hao will not simply think about the problem of decades, maybe after the wooden tower blows, there is also a layout to resist the northwest wind and not make it tilt to the southeast. But a fire made the answer never clear

Five years later, Song Renzong issued an edict to imitate the style of the wooden tower to build this iron-colored glazed brick tower, which was also built when it was first tilted to the northwest direction, and then slowly became positive under the day and night blowing of the northwest wind, at this time it was already somewhat inclined to the southeast, but it could not be seen without careful observation.

Although later craftsmen copied Yu Hao's design, they did not have Yu Hao's ability, and could not build a 360-foot tower, so they had to reduce the original height by half and build a 180-foot iron tower.

Many people who come here are not looking at the iron tower in front of them, but reminiscing about the reincarnation of Lu Ban - Yu Hao.
