Hongwu Daming: Why hasn't my son rebelled?

Chapter 115 The Heart of His Royal Highness Liao

There has recently been a trend among the students in the Imperial College.

That is to go to teacher Zheng Shiyuan's math class.

The so-called mathematics is a science that evolved from the mathematics of the Tang Dynasty in ancient times, and it is called mathematics.

Of course, this is what Mr. Zheng Shiyuan said, and Mr. Zheng Shiyuan said, this is what His Royal Highness Liao Wang said.

Good guy, Tang Dynasty numerology?This is a lost technique!

And Zheng Shiyuan's lectures are also very good.

He didn't talk about boring and esoteric mathematics when he came up, but he started to talk about the history of mathematics.

Students these days may not have much interest in mathematics itself.

But they are all very interested in historical events.

After all, the exam is a test, and when you talk to people, if you don’t know allusions to others, wouldn’t that make you laugh?

Confucian scholars still need to save face.

So from history as an entry point, that is perfect.

Zheng Shiyuan started talking.

In the legendary Tang Dynasty, officials were selected by numerology. "Sunzi Suanjing" and "Five Cao Suanjing" are the basic knowledge for beginners, and it takes one year to learn.

The primary courses are "Nine Chapters of Arithmetic" and "Sea Island Mathematical Classics". The three-year schooling period includes quadratic equations in one element, calculation of pi by cutting gardens, etc. There are also many contents of measurement mathematics. During the Tang Dynasty, maps in military camps, Geographical surveying and mapping, you must learn these.

The intermediate courses are "Zhangqiujian's Suanjing", "Xiahouyang's Suanjing", "Zhoubi Suanjing", "Five Classics of Numeracy", etc., which are also three-year schooling, involving square root, cube, and Pythagorean theorem, including Baiji The solution of this system of indeterminate equations.

Advanced courses, including "Jigu Suanjing" and "Zhushu".

This is really related to the category of advanced mathematics, and the solution of high-order equations was even more proficient in the Tang Dynasty.

This stage will take seven years.

Forget it, add it all together, it takes 14 years of study in numeracy alone before you can graduate.

According to a person's 14-year-old entry into the official school, learning mathematics, until nearly 30 years old, can be able to complete all studies and graduate.

It is conceivable how difficult and important this numeracy is.

At that time, there was a very famous teacher named Wang Xiaotong, the doctor of mathematics at that time, Tai Shicheng.

In the official school, there is no student who is not afraid of him. There is no other reason. The math problems he gave are really tormented.

Learning mathematics after him is really easy to lose hair.

Of course, many of these things have been lost. For example, "Ji Gu Suan Jing" and "Zi Shu Shu" did not have complete texts during the Hongwu period.

It is only recorded in some historical materials.

Even for the questions in "Nine Chapters of Arithmetic", His Royal Highness Liao Wang had previously published a list in the whole city, but only three people answered it!
You know, in the Tang Dynasty, this "Nine Chapters of Arithmetic" was something that teenagers learned!
During the Hongwu period, no one would!
Some students were unconvinced and might want to refute:
"Teacher, what you said is something learned by the ancients, but according to the students, we should learn more about the principles of the sages now. This numerology is the way of merchants, and it is not very important."

After he finished speaking, Zheng Shiyuan smiled and did not criticize him, but said:

"Let's not talk about how important it is to draw a map and determine the height of lakes and mountains. Let's talk about the sage's truth you said."

Zheng Shiyuan put his hands behind his back and said:

"As we all know, I am now honored to be the chief official of His Royal Highness the Liao King. I am ashamed to say that although I am a senior official, His Royal Highness Liao is very talented, and I really can't teach much.

Although I don't teach much, I can often sit and discuss with His Royal Highness King Liao on weekdays.

I have heard some unique insights from His Royal Highness Liao Wang.

To sum it up in four words, the unity of knowledge and action. "

Unity of knowledge and action?

After Zheng Shiyuan finished speaking, there was an uproar following the explanation, followed by the students began to discuss.

"Zhu Zi said, shouldn't one act ahead of time?"

"Yeah yeah."

What everyone was learning at this time was mostly Zhu Xi's theory, and everyone was quite surprised to hear different opinions at this time.

And Zheng Shiyuan also knew everyone's attitude. He was quite surprised when he heard His Royal Highness Liao Wang casually talk about Xinxue at first.

But His Royal Highness King Liao looked as usual, and he didn't feel that there was anything wrong.

Zheng Shiyuan didn't know that this was a new Confucian theory at first, but Zheng Shiyuan talked a lot with the Liao king, and he also discovered the subtleties of it.

Moreover, King Liao also said that this is called Mind Learning.

For a period of time, Zheng Shiyuan has been recording the words and deeds of King Liao while pondering over the meaning of this philosophy. Of course, most of them are like Confucius' disciples, recording Confucius' words and deeds.

And these remarks of the Liao King Zhu Qi, gathered together, opened a new door in front of Zheng Shiyuan.

Zhu Qi is not good at philosophy.

But Zhu Qi can chat, can talk!
Psychology is so famous, that kind of profound and difficult to understand philosophical theory. When I was in history class, the history teacher talked a lot, and he just opened his mouth.

As for what he said, "knowledge comes with action, and action comes with knowledge", Zhu Qi didn't think much about it, after all, his thinking was already materialistic.

But Zheng Shiyuan would think about it over and over again, and now he also said the original words that His Royal Highness Liao Wang said in class.

Good guy, when this theory was released, it immediately exploded.

The first class was spent in a philosophical discussion.

This is also what Zheng Shiyuan did not expect.

But also because of the emergence of the theory of mind, it was said by such a well-known figure as His Royal Highness King Liao, and Zheng Shiyuan, a master of Confucianism, also supported it.

Among the students of the Guozijian, there was also an uproar.

In the second class, even more people came.

Part of it is for mathematics, and the other part is for this heart.

Good guy, these Confucian scholars like to discuss such philosophical issues.

But it doesn't matter whether it's for the reputation of Zhu Qi, king of Liao Dynasty, or for discussion and learning.

In the recent period of time in the Guozijian, there has been a strong atmosphere for discussion and study.

They finished discussing in class, so naturally they couldn't be idle in private.

What kind of private gatherings, poetry gatherings, or even ordinary meals and drinks, they all have to chat vigorously.

Starting from the Guozijian, a wind of revival of mathematics in the Tang Dynasty, and a wind of exploring the mind of His Royal Highness Liao Wang, unknowingly turned up like this.

Then, this breeze gradually gathered and became out of control.

------

In the ninth year of Hongwu, May.

Zhu Qi was sleeping soundly on the bed when he heard footsteps outside.

Zhu Qi opened his eyes in a daze, and as soon as he felt that there was no one around, he knew that Xu Miaoyun must have woken up early again.

The footsteps outside were getting closer, and then I heard the voice of an internal officer:

"Your Highness, Your Majesty tells you to go up to court quickly."

Zhu Qi was taken aback for a moment, and was mostly awake.

Go to court?What court do you go to?I am a feudal prince without a position, what am I going to do?

Fortunately, the internal officer followed up and said:
"The ministers are all waiting, saying that they want to have a good discussion with His Highness."

On the Road?On what way?
