Yan Chengjin asked He Neng to hold up the letter and take a closer look.

A crane flies to a mountain, to be exact, to a gold ingot, tethered by a rope.

The painting skills are extremely poor, but you can guess the meaning.

The island country has a silver mine, which supplied one-third of the world's silver during the Ming Dynasty.

The mineral heritage is outrageously rich.

It's called Iwami Silver Mine!

The Zhang brothers went to the Iwami Silver Mine?

Since it is a letter of distress from the Zhang brothers, then ...... Yan Chengjin said to He Neng: "I don't understand, it's burned." ”

He Neng trotted and brought the brazier, and burned the letter paper together.

The next day, early in the morning.

Yan Chengjin sat in the sedan chair, and when he arrived at the entrance of the alley, he saw a widow squatting at the base of the wall.

The Japanese people looked at the sedan chair, as if they did not dare to come, glanced at the sedan chair and left.

Yan Chengjin entered the palace from the side gate of the noon gate, followed the flow of officials from the early dynasty, and came to the Fengtian Palace.

After the liquidation of the Yellow Book, Emperor Hongzhi was quite dissatisfied with the arithmetic of the household department.

If the DPRK and China invite outsiders to settle the major events every year, what kind of system will it become?

Moreover, he wanted to shorten the length of the inventory.

"Ten years is too long, I want to liquidate the Yellow Book once every three years as a rule."

The hundred officials glanced at each other left and right.

It takes several months to liquidate a liquidation, and it requires a lot of manpower.

Han Wen was puzzled: "Your Majesty, the liquidation of the Yellow Book is quite complicated, and it requires several main books to proofread and liquidate, in addition, there are many accounts such as begging, military salaries, silver relief and taxes, and the household department is really unable to do it. ”

The repair in the palace and the use of the vassal king must also be liquidated, relying on the household department alone, three, six, five plus zero and seven can't be counted.

Moreover, Da Ming used abacus, which was far less fast than a calculator.

Yan Chengjin fell into deep thought, His Majesty's intention was obvious, and he would make a short-term inventory to prevent the paddy fields from shrinking again.

Emperor Hongzhi looked at Zhang Sheng with burning eyes: "The officials of the household department and the Hanyuan don't know anything about arithmetic, I think the problem lies in the Ministry of Rites, how does the Ministry of Rites plan to rectify it?" ”

The Ministry of Rites is in charge of the imperial examination, which is in charge of the education of the Ming Dynasty.

The selected officials are not as good as the businessmen in the market, of course he has to ask.

Zhang Sheng's pressure increased: "The ministers will strengthen the teaching of arithmetic. ”

There are only three township exams and general exams.

In the first session, there was a poem with eight strands and a poem with five words and eight rhymes.

In the second session, one of each of the Pentateuch.

In the third session, there are five questions.

The imperial examinations of the Ming Dynasty, as well as the imperial examinations of previous dynasties, did not take arithmetic.

This led to the fact that the officials in the imperial court were not as good as the businessmen who did business in the market.

In the Song Dynasty and the Yuan Dynasty, the development of Tianyuan art flourished, and if it was promoted, the Ming Dynasty might become the world's first mathematical power.

But in the Ming Dynasty, it suffered from faults.

Yan Chengjin stood in front of the queue in the Metropolitan Procuratorate and said nothing.

The matter of restructuring needs to be said carefully.

……

Ministry of Rites Duty,

Zhang Sheng picked up the paperweight and thought hard for a long time, not knowing how to tidy it up.

"The scholars of the country and the scholars of the world all despise arithmetic, and it is really difficult for Your Majesty to be an official."

"If it's just to liquidate the Yellow Book, it's really a lot of work." A master of the Ministry of Rites sighed.

The foundation of the Ming imperial examination is still the Bagu text, which is to read the books of sages.

What has nothing to do with the book of the sages is a sideshow.

If the Ministry of Rites decrees that scholars all over the world deliberately learn abacus, it will shake the reading atmosphere of the Ming Dynasty.

Therefore, Zhang Sheng's will was written cautiously, and he thought about it for a long time, but he has not yet put it down.

After getting off duty, I went back to the house.

Zhang Sheng changed into Confucian clothes, sat on the brocade stool, and couldn't help sighing a few times.

"Dad, the people take food as the sky, eat first, and it's not too late to sigh after eating."

Zhang Yuanxi looked at the sweet and sour carp with a blank eye.

Dad is a scholar of the Ministry of Etiquette, so he pays attention to etiquette, and if the elderly don't move the chopsticks, he can't move the chopsticks.

"Daddy can't eat it!"

"The boy...... Still eating or not? ”

Zhang Sheng ignored him, and said to himself: "Your Majesty asked my father to rectify arithmetic, but arithmetic is not the knowledge of the imperial examination, and everything that should be taught has been taught, how else can it be rectified?" Huh. ”

"Dad, Xie Yu's arithmetic is also learned from Liangxiang, Liangxiang has the college exam of the College of Science, Dad might as well ask Wang Shibo." Zhang Yuanxi often goes to the Qingshan Library to meet friends, and he knows a little bit about it.

Zhang Sheng's eyes lit up, and he hurriedly called someone to prepare a sedan chair.

After a short time, they arrived at the palace.

Wang Yue returned to Beijing from Liangxiang, and when he heard that Zhang Sheng was coming, he laughed and walked from the back hall.

"Brother Qizhao, I can't avoid the old man on weekdays, today, how can I take the initiative to visit, it really makes the old man flattered, hahaha"

Zhang Sheng's old face turned red, Wang Yue had a bad reputation in the past, and few officials were willing to associate with him.

"I don't hide it, it's something to ask for, Your Majesty wants to rectify the household department and the Ministry of Rites, I want the handouts of Liangxiang."

Officials in the DPRK and China have monthly assessments, and if a paper of arithmetic questions is published, the arithmetic will be raised.

Zhang Sheng thought so.

Wang Yue groaned: "This... It's a secret thing, and the official can't divulge it. ”

The next day, Yan Chengjin was in the moon cave of the noon gate and was blocked by someone.

"Why did Lord Zhang block this official?"

Although this kid is not likable, he knows how to be polite.

Zhang Sheng dragged Yan Chengjin to the court, and said hurriedly: "Your Majesty ordered the official to rectify the arithmetic, I heard about Xie Yu's arithmetic, and I am accustomed to the good township, and the handouts and arithmetic papers of the good township, you give the official a copy." ”

He still had a hundred taels of silver in his hand, and shook it in front of his eyes.

Yan Chengjin looked at it for a long time and spit out four words: "The lower official refuses." ”

"You!" Zhang Sheng was furious.

Zhu Houzhao went to school in Zhan Shifu, and when he saw Zhang Sheng and Yan Chengjin sneaky, he walked over: "Old Gao, Master Zhang held you hostage?" ”

"Your Highness is going to talk nonsense, this official and Lord Yan are talking about business!" Zhang Sheng emphasized angrily.

Yan Chengjin said: "The lower officials don't sell it." ”

After that, he went to the left door to line up without looking back, preparing to go to the morning court.

Zhang Sheng sighed, shook his head, and followed towards the left door.

The golden bell rang, and hundreds of officials walked into the East Warm Pavilion one after another.

The cabinet and the six ministries, after each playing, it was the turn of the Metropolitan Procuratorate.

"Yan Qingjia, I see you have something to say."

Emperor Hongzhi has been in the early dynasty for fifteen years, who has something to hide, and he can see it clearly through his demeanor.

This guy stands at the forefront of imperial history, and he can see it very clearly.

Yan Chengjin bowed slightly: "The minister thinks that it is better to implement the Tianyuan technique than to implement the Tianyuan technique, and let Xie Yu be the doctor of the Guozijian to teach arithmetic." ”

Although he didn't help Zhang Sheng, he could take the opportunity to promote arithmetic.

The flourishing business of the Ming Dynasty led to the abacus, which was circulated among the merchants, that is, the abacus.

The root of Tianyuan is calculation, that is, to solve a quadratic equation and a cubic equation.

In the Song and Yuan dynasties, the ancestors already knew how to solve equations.

This is a huge progress, but unfortunately, in the Ming Dynasty, it was not inherited and promoted.

Not only did the Ming lag behind the West, but it also made the Ming Dynasty not prosperous.

Arithmetic is the foundation of all learning, even more important than the Four Books and the Five Classics.

If the Tianyuan technique is promoted, the shock in history can be called the Renaissance of the East.

Emperor Hongzhi and Li Dongyang and others didn't know what Yan Chengjin was thinking, in their opinion, arithmetic was just a chicken rib discipline used in the household department, and they didn't care.

Ma Wensheng bluntly retorted: "The doctor is the official position of the Guozijian, how can he let the businessman hold it?" ”

His Majesty and the hundred officials did not mean to attach importance to the Tianyuan Technique.

Yan Chengjin understands them, who has nothing to do to solve a quadratic equation to play?

If you don't take the imperial examination, it is a dishonorable business to be a businessman.

In such an environment, arithmetic is destined to be unable to be implemented like Baguwen.

If we want to implement it, we must change the general environment, that is, change the examination method of the imperial examination.

This move is as difficult as climbing to the sky.

If it is not implemented, there will be a fault in arithmetic in the Ming Dynasty.

Now is an opportunity, Zhang Sheng is forced by His Majesty's will, and the Ministry of Rites needs to be restructured.

"What the officials said is very true, although I appreciate Xie Yu's arithmetic, but Xie Yu is a businessman and cannot be directly promoted to an official."

There is only one way for the Ming Dynasty to be an official, which is the ancestral system.

No matter how good the person you recommend, after all, he is a grass people, and I can't make an exception to abolish the ancestral system for the sake of a businessman.

Hundreds of officials thought so.

But Yan Chengjin continued: "There is no need to be promoted to an official, and setting Xie Yu as a guest doctor of the Guozijian is not a violation of the ancestral system." ”

Emperor Hongzhi didn't understand, could it be that I was lonely and unheard?

He looked at the erudite Li Dongyang, who was also red-faced and confused.

"What do you mean... What is a Visiting Doctor? ”

In the opinion of Liu Jian and others, the past dynasties have never heard of such a doctor.

"The visiting doctor has no official position and is not subject to the court's favor, and when he lectures, he only needs to pay Xie Yu a few pennies.

Although Xie Yu is a businessman, the sage said that people are not born to know, there is no order to learn, and those who reach are the first.

If Your Majesty wants to improve his arithmetic, why stick to one title? ”
