Chapter 198: Zhu Yijun

"There are indeed many things that can be done or cannot be done, but for some people, it is absolutely impossible; but for some people, it is not impossible." Zhang Siwen said a sentence to Jiao Hong, a sentence that was not easy to understand and had profound meaning.

The purpose of setting some regulations is to set thresholds, and then use reasonable means, using the power in one's hands to seek private gain. This kind of thing is really too common, even in the relatively fair imperial examinations, it is included.

Threshold, threshold, if you pass it, it is a door, if you can't pass it, it is a threshold.

Jiao Hong was silent for a moment before saying, "From the Hongwu era to the Xuande era, the examination and promotion of Great Ming officials, after three examinations and nine years, could become officials. Tiling, Duli, Yuanshi, Lingshi, Dianli, Sili, and Shuli could all be given official status. But in the seventh year of Xuande, they began to examine literary meaning, official documents, and writing, which basically cut off the opportunity for officials to be promoted to official status."

"Those who have nothing to take in all three will be dismissed as commoners."

This was the decree of the seventh year of Xuande. After that, the door for officials to be promoted to official status was completely closed.

The officialdom of Great Ming has a universal ceiling. If you are not a Jinshi, you cannot enter the Hanlin Academy; if you are not in the Hanlin Academy, you cannot enter the Cabinet. By the Wanli era, it became that only Shujishi had the qualifications to enter the Cabinet; Jinshi are also divided into three grades. The top three enter the Hanlin Academy, the second grade takes the Hanlin Academy exam, and if they don't pass, they can seek a position in the capital. The third grade can only be sent out to be officials.

As for Juren, when they were first opened, there were still high officials. By the Wanli era, the upper limit of Juren was the sixth rank.

This Metropolitan Examination is a carp leaping over the dragon gate.

So Jiao Hong really has no ambition for officialdom, which is why he confronted Sun Jiegao face to face and scolded the Confucian scholars. He knew that a person like him could not settle himself in the officialdom.

Everyone is greedy, are you greedy? Everyone is indulgent, are you indulgent? Everyone turns a blind eye to a certain thing, can you turn a blind eye? Jiao Hong has confidence in his own learning, but he has no confidence in being an official.

If it weren't for taking refuge in the Quan Chu Quanchu Quanchu Huiguan this time, he wouldn't even be able to take the exam.

"Because of my father, I don't intend to be an official." Zhang Siwen's words were shocking, directly throwing out an explosive topic, making Jiao Hong dumbfounded and speechless.

As Zhang Juzheng's eldest son, isn't it a matter of course for Zhang Siwen to enter the officialdom and rise to the top?

Zhang Siwen saw Jiao Hong's stunned look and said with a smile, "Although my father has never said this, if I pass the exam this year, I am afraid someone will say that my father wants to be a powerful official, wants to be Yan Song or Xu Jie. I'd better not cause trouble for my father. He already has enough trouble."

"I have a place to go even if I don't become an official. I plan to learn mathematics well and then enter the Pavilion of Investigation."

"Pavilion of Investigation?" Jiao Hong was full of doubts. What kind of yamen is this?

Zhang Siwen began to explain the various aspects of the Royal Pavilion of Investigation. This Royal Pavilion of Investigation was still under construction.

Zhang Siwen yearned for the Pavilion of Investigation. His mathematics was excellent. With the help of various novel objects in his father's Wenchang Pavilion, he could flexibly use the eighty-one-file large abacus, could use the step-measuring vehicle to measure the area of irregular land between the two, could use the sine table for trigonometric drawing, and even personally made a 10-point sine table.

At this time, he was fully qualified to enter the Pavilion of Investigation.

Zhang Siwen clearly knew that he had no future in politics. His father, Zhang Juzheng, did not intend to leave the big mess of the Zhang Dang to him, Zhang Siwen. That was left for His Majesty.

Zhang Siwen did not feel unfair. His father had talked about the theory of public and private. The Zhang Dang is public, and the small family is private. If Zhang Juzheng wanted to leave these to his son, it would be impossible to have the Zhang Dang.

Zhang Siwen liked mathematics. In the past, he was a bit rebellious and had no place to use his skills. Now, the Pavilion of Investigation, built with mathematical logic as the core, was the holy temple in his mind and the place he yearned for now.

Jiao Hong and Zhang Siwen chatted for a long time. Jiao Hong was very interested in the Pavilion of Investigation, but he had never learned mathematics at all.

The next day, Jiao Hong entered the Imperial Academy and became a student of the Imperial Academy. There were not so many problems with taking the exam.

Jiao Hong had the background of a Juren, so entering the Imperial Academy was not a difficult thing.

Sun Jiegao immediately did not dare to continue making things difficult. The reason was very simple: Jiao Hong was a person of the Quan Chu Quanchu Quanchu Huiguan. Continuing to make things difficult would be not giving the Grand Secretary face.

Not giving the Grand Secretary face is looking for death.

After Jiao Hong entered the Imperial Academy, he immediately regained his confidence. Poor students have many stationery items. These students, the etiquette is indeed comprehensive, but in terms of learning, they are not very good.

Jiao Hong entered the Imperial Academy to learn mathematics.

But soon Jiao Hong noticed the difficulty of mathematics.

The mathematics of the Imperial Academy is a separate credit system.

Jiao Hong just enrolled, entered the Degree Hall, twelve exams a year, ten-point system, highest ten points, lowest 0 points. Every year, he must score 90 points to be promoted from the Degree Hall of "Introduction to Mathematics" to the Side Hall to read "Mathematical Treasure Mirror", "General Principles of Algorithms", and "Western Algorithms".

After another year of exams, passing 90 points, he could enter the Mingli Hall. Mingli Hall is the disciple of the Prince Zhu Zaiyu, responsible for the grading of the Degree Hall and the Side Hall.

The Imperial Academy originally had six halls. The academic system of the Zhengyi, Chongzhi, and Guangye halls was one and a half years. In addition to the original grades, the mathematics grade must reach 60 points to be promoted to the Xiudao and Chengxin halls. The academic system of these two halls was also one and a half years, and the mathematics grade must reach 80 points or more to be promoted to the Luxing Hall, obtain the qualification of a child student, and start preparing for the provincial examination.

Mingli Hall and Luxing Hall are the two "Upper Houses" in the Imperial Academy.

Xiudao, Chengxin, and Side are middle houses, while Zhengyi, Chongye, Guangye, and Degree are lower houses.

The upper, middle, and lower three houses are three grades.

If a Juren enrolls, he will be inserted into the Xiudao Hall. For students with a Juren background, the Imperial Academy has no requirements for attending classes or taking exams, because most Juren enter the Imperial Academy to get an identity, mainly for the Metropolitan Examination.

When Jiao Hong started learning mathematics, he didn't feel anything terrible at first. Isn't it just addition, subtraction, multiplication, and division? But as the topics gradually deepened, Jiao Hong began to feel numb, and then his scalp began to feel numb.

He even doubted how he passed the Juren exam, whether his father had used silver to open the way for him without him knowing.

The Introduction to Mathematics directly knocked him out. Is this thing called mathematics really something people learn?

The academic official stood in front and said, "I have a pot of wine, carrying the pot to walk in spring, meeting a shop and doubling it, meeting a friend and drinking a dou. The shop and friend passed four places, and the wine in the lake was gone. Borrowing to ask how many dou were originally in this pot."

This tests mathematics and logic. After repeated calculations, Jiao Hong finally got a result, but he calculated it wrong. He pushed it backward and calculated the shop one less time, so he calculated it wrong. Instead, he used the Tianyuan technique and walked forward once, but calculated it correctly.

The answer is: 15/16 dou.

Jiao Hong found a new fun.

On the third day of the tenth month, Zhu Yijun came to the Wenhua Hall as usual, held a grand court meeting, and started the monthly regular court.

After seeing the grand ceremony, everyone looked at the Emperor on the stage.

Feng Bao flicked his whisk and said loudly, "Proclaim the envoy of the Ryukyu Kingdom to pay respects."

"The minister, Zheng Xian, Right Councilor of Ryukyu, the minister, Zheng You, Long-term Historian of the Zhongshan King's Mansion of Ryukyu, pay respects to Your Majesty, Long live Your Majesty, Long live Your Majesty, Long live Your Majesty." The two Ryukyu envoys entered the hall and performed the grand ceremony.

Zheng Xian and Zheng You bowed again. Zheng Xian bowed his head and said, "Your Majesty, the former King has passed away. I beg Your Majesty to confer the title of King on the Prince Shang Yong."

The Ryukyu envoy entered the court this time to request the Emperor to confer the title of Zhongshan King on the new King of Ryukyu, Shang Yong. The old King died, and the new King had already taken charge of the government, hoping to get the conferment of the imperial court.

"I don't understand this matter. The Ministry of Rites has already reported it. The Prince of the King was originally Shang Kang, why support Shang Yong as King?" Zhu Yijun asked with furrowed brows.

According to the "Ritual Notes of the Vassal States", the Prince of the King set by the old King was clearly Shang Kang. The Prince of the King Shang Kang was still alive, but the officials of Ryukyu supported Shang Yong as King. This must be asked clearly.

"Reporting to Your Majesty, Shang Kang Bo was not born of the legitimate wife." Zheng Xian bowed again and answered very respectfully.

The Minister of Rites, Ma Ziqiang, came out of the class and bowed to pay respects, then turned to look at the Ryukyu envoy and said, "Is it really like this? But the Shang Yong you support is also not born of the legitimate wife."

In the 6th year of Longqing, the old King had already passed away. The reason why Great Ming had been delaying the conferment of the new King was certainly because of the fierce court struggle. On the other hand, it was because the Ministry of Rites supported the Prince of the King set by the old King, but the bureaucrats of Ryukyu supported another one, which was not in accordance with the rituals.

So until the fourth year of Wanli, the new King had not been conferred.

And recently, the ninth-rank coastal defense inspectors drove hydrofoil sailboats on the sea, from Songjiang Prefecture to Ryukyu in only one day, and from Yuegang to Ryukyu in only two days. The speed of information transmission had been greatly improved. After recent visits, it was found that the Ryukyu problem was not just: not born of the legitimate wife.

The mother of the new King supported by Ryukyu was Japanese, while the mother of the Prince of the King Shang Kang was Great Ming.

Ma Ziqiang didn't make it clear, just giving the Ryukyu envoy a chance to make it clear. Wanting to jump left and right and play both sides in Great Ming, don't even think about it. On the decision-making regarding Japan, a firm stance is needed.

Zheng Xian's forehead immediately broke out in cold sweat. The imperial court already knew.

"Your Majesty, please allow the minister to report in detail. It is not that the Ryukyu military and civilians have abandoned Great Ming, but that the Japanese pirates are harming the Ryukyu islands, causing endless harm. I beg Your Majesty to send the Great Ming Heavenly Army to help Ryukyu pacify the Japanese pirates." Zheng Xian didn't make it clear either, but explained the reason clearly.

As a vassal state of Great Ming, the King of Ryukyu had to be conferred by the Emperor of Great Ming. But the reality was that Ryukyu was repeatedly invaded by Japanese pirates. As the suzerain state, it had no ability to help clear the Japanese pirates.

The Japanese were fierce, fighting everywhere, occupying ports and fertile land. The Ryukyu envoy entered Ming and complained every time, but the imperial court could only say two nice words.

Great Ming has Great Ming's national conditions, and Ryukyu also has Ryukyu's national conditions. Ryukyu is heavily infiltrated in all aspects. In fact, it is a way without a way. It can only play this kind of fence-sitting trick, on one hand listening to the orders of the Shimazu family of Satsuma, on the other hand seeking the conferment of Great Ming.

Zhu Yijun nodded and said, "Proclaim the edict."

Feng Bao came out, flicked his whisk, and said with a yin and yang tone, "By the order of the Emperor, the edict says:"

"I have received the mandate of heaven to rule the universe. All political orders are announced, and only the established constitution is followed. You, Ryukyu Kingdom, are far away in the corner of the sea. The sound and education have been gradually covered, and the duty has been effective for a long time. The former King Shang Yuan, clearly received the title of conferment, and now passed away. The vassal state requested conferment, and still bestowed with leather caps, crowns, and clothes, etc. You should carefully observe the rituals and increase your loyalty and diligence."

"As decreed."

This imperial edict is very interesting. Although it bestowed leather caps, crowns, and clothes, it still did not acknowledge that Shang Yong was the King, only letting Shang Yong temporarily take charge of the country's affairs, and there was no corresponding seal, nor was an official sent to Ryukyu to preside over the conferment.

Great Ming had not yet fully investigated the situation in Ryukyu. The speed of Great Ming's navy's revitalization was much lower than the revitalization of the Beijing camp. This was not that Yu Dayou was not as good as Qi Jiguang, but because the navy needed ships, and building ships took time. Without ships, cannons, and guns, the navy wanted to land and fight, which was really difficult.

And Yu Dayou gave a clear time, that is, around the 7th year of Wanli, Great Ming's navy would have the ability to attack.

So, Ryukyu had to wait, and Great Ming also had to wait.

"The minister kowtows to thank Your Majesty for your great kindness." Zheng Xian sighed heavily. This result was not very good.

Zheng Xian was actually not reconciled. Either the imperial court sent troops to pacify the Japanese pirates, then Ryukyu directly attached itself, and everyone was happy; or the imperial court directly conferred the title of King, acknowledging Japan's influence in Ryukyu. But Great Ming neither swallowed nor swallowed, neither willing to send troops nor willing to confer the title, making Ryukyu neither up nor down, very uncomfortable.

Zheng Xian was not reconciled but had no way. Great Ming could not give up the claim to Ryukyu. It wouldn't in the past, and it wouldn't now because of the maritime affairs. But Great Ming's navy had not yet recovered to the point of attacking, which required time to accumulate, so it could only be neither up nor down.

The imperial court is difficult, and Ryukyu is also difficult, so they can only reluctantly maintain the situation.

After the envoy left the hall, Zhu Yijun's hand reached for the memorial. This pile of memorials was all the memorials of this month.

"Is the Hanlin Academy reviewer Xu Guochong here?" Zhu Yijun held the memorial in his hand and said with a playful face.

Xu Guochong was waiting outside the hall. He heard the proclamation and rushed up to the hall, knelt on the ground, trembling and saying, "Paying respects to Your Majesty, Your Majesty's holy body is safe."

Zhu Yijun held the memorial in his hand and said, "You submitted a memorial saying that this mathematics is a demon-delusional technique, falsely saying that numbers have divine principles, can know the coming and hiding, and nothing is not reached. It says: Mathematics is useless, not only for governing the world, but also for wasting effort in vain, and it is useless for a hundred things."

"I rejected it for you, and you still submitted a memorial saying to reduce the burden."

The first stumbling block of mathematics was rendered by Confucian scholars as a demon-delusional technique.

For example, in the past, Li Chunfeng engaged in astronomical calendar, and when Wu Zetian ascended the throne, someone said that Li Chunfeng had deduced forty years ago that Wu Zetian was going to usurp the Li family's country!

The Heavenly Family and the mathematician Li Chunfeng were hard-pressed to become prediction masters.

There was even a "Tui Bei Tu" (Pushing Back Chart) that didn't know if it was written by Li Chunfeng himself, which processed the prophecies of past dynasties and finally became the top of the top of prediction studies. But as long as there was something, this Pushing Back Chart would be taken out for hype.

Things like the Pushing Back Chart actually have very obvious traces of collective creation, and it is not only horizontal, Li Chunfeng leading many people to create, but also vertical, processed by past dynasties, forcibly attaching things to the Pushing Back Chart, and finally creating a kind of illusion that it predicts very accurately.

This thing is deceptive. For example, something happened in August of the 4th year of Wanli. A Confucian scholar named Ma Dengru, because he didn't study well, started to tinker with some gods and ghosts, which in Great Ming is called "serving demons".

Shu Ao of Huai'an Prefecture submitted a memorial saying: Ma Dengru's writing is not successful, and his martial arts are not successful, so he serves demons and creates "Pushing Back Chart" and "Formation Chart", which has evidence of confusing the public.

According to the Great Ming Law, rumors of spreading prophecies must be beheaded and displayed to the public, so he was directly escorted to the capital.

Creating "Pushing Back Chart" is self-made, which is the best way to cheat.

And now the reviewer Xu Guochong means that Great Ming's promotion of mathematics is fueling the arrogance of demon-delusional techniques. This worry cannot be said to be wrong, because past dynasties have all said so. Mathematics is a tiger helping the evildoer, and mathematics is the ghost of demon-delusional techniques.

And on the other hand, Xu Guochong is also practicing the reality, this thing is too difficult.

Zhu Yijun rejected Xu Guochong for the first time. The second time, Xu Guochong didn't talk about demon-delusional techniques, but pleaded for the students of the Imperial Academy, loosen the reins, which could be considered telling the truth.

It's too difficult, and they can't learn it at all.

Zhu Yijun thought for a while and said, "Reviewer Xu has a different opinion from me. Reviewer Xu says it's difficult, but I also study it. Why do I feel it's not difficult? I have an idea."

As soon as the Emperor said he had an idea, the officials were scared. His Majesty's ideas were always so unexpected. Your Majesty, please don't have any more ideas. The Great Ming court has been made unable to live by His Majesty's ideas.

Zhu Yijun didn't care whether the officials were willing or not, and said with a smile, "Then I will go to the Yilun Hall tomorrow to lecture on mathematics. Why don't I lecture on the recruitment difference technique?"

The Yilun Hall of the Imperial Academy was called the Chongwen Pavilion in the Hongwu era. In the Yongle era, it was renamed the Yilun Hall. It is where the Emperor visits the Imperial Academy, and the Emperor lectures there. When the Emperor goes to this place, it is to see the officials of the Imperial Academy, and then the Minister of the Court of Ceremonial Rites conveys the decree to announce to the teachers and students that they should study hard and respect teachers and Taoism.

Zhu Yijun felt that since it was a place for lecturing, could he, the monarch and teacher, personally be a teacher and lecture on mathematics to the students of the Imperial Academy?

Zhu Yijun asked himself that his reading of the Four Books and Five Classics was not bad, but the Imperial Academy lectured very well on the Four Books and Five Classics, but this mathematics was not lectured very well.

Monarch and teacher are one, so fulfill his duty as the monarch and teacher of the world and personally lecture on it.

Isn't it that they can't? Zhu Yijun planned to go into battle himself and lecture on the recruitment difference technique.

The recruitment difference technique was created by Guo Shoujing, Zhu Shijie, and others during the Yuan Dynasty, and was used extensively in the Shoushi Calendar and the Jade Mirror of Four Elements. The recruitment difference technique is called Newton's interpolation formula in later generations.

Zhang Juzheng heard the Emperor say this and hurriedly came out of the class and bowed, saying, "Your Majesty, I think it is better to lecture on the four-element technique. The recruitment difference technique is too difficult."

Zhu Yijun said very confidently, "Is the teacher afraid that I can't explain it clearly? Didn't I demonstrate the recruitment difference method to calculate the visual degree of the sun, moon, and five stars to the teacher in the side hall yesterday? That was when reading the theory of astronomical operation."

"I can explain it clearly, teacher, don't worry."

Zhang Juzheng was not worried about the little Emperor, he was worried about the students.

"Your Majesty can understand, but the students don't understand. I am not worried that Your Majesty can't explain it clearly, but I am really worried that the students can't understand it, and will be even more terrified of the heavenly power and mathematical principles, and will be even less willing to learn." Zhang Juzheng did not want to stop the Emperor from going to the Yilun Hall to lecture to the students, but if His Majesty came up and engaged in the recruitment difference method, wouldn't that be killing people?

Lecturing is fine, but it cannot be lectured so difficultly, otherwise the students will not understand, and His Majesty will also feel that the students are too stupid, which will damage the friendship between the monarch and the minister.

"Then how about lecturing on Zu Geng's 'if the power of the power is the same, then the accumulation does not allow difference'?" Zhu Yijun actually didn't want to lecture on the four-element technique, it was really too simple.

"Your Majesty, I think the four-element technique is just right. If it is more difficult, the students will probably not be able to realize Your Majesty's earnest teachings." Zhang Juzheng heard that he wanted to lecture on Zu Geng's principle and immediately opposed it clearly. In the Imperial Academy, Zu Geng's principle is also studied in the Mingli Hall. Letting the students learn this, they won't be able to learn it, right?

Earnest: earnest, patient teaching.

"Alright then, I will go to the Yilun Hall to lecture on mathematics on the afternoon of the third day of every month." Zhu Yijun followed his own teacher's admonition and chose the simpler four-element technique for explanation.

After Zhang Juzheng succeeded in compromising, the court officials all breathed a long sigh of relief. Zhang Juzheng fulfilled his mission as the Grand Secretary and successfully sealed the Emperor.

If he really let His Majesty lecture on the recruitment difference technique, and the students didn't understand, wouldn't they have to hang themselves to apologize?

The four-element technique is simple, so it is just right.

Zhu Yijun was still a bit regretful. Actually, he really wanted to lecture on this trigonometric surveying method. This was the greatest achievement after Zhu Zaiyu entered the capital, and now it had already begun to be calculated. The geography map, which was seriously out of proportion before, could finally be further corrected.

Lecturing on the trigonometric surveying method can effectively respond to the first kind of public opinion, that mathematics is useless and mathematics is a demon-delusional technique.

It is that they don't know how to use it and can't learn it, falsely attributing it to mathematical principles, not that there is a problem with mathematics, but that there is a problem with people.

But the trigonometric surveying method is also frontier mathematics that only Mingli Hall will come into contact with.

"How does Reviewer Xu think of my handling? Look, you say it's difficult, I feel it's not difficult, so I will go to lecture to the students of the Imperial Academy." Zhu Yijun seemed to be asking Xu Guochong whether he agreed with him going to lecture.

Whether Xu Guochong agreed or not, he had to agree.

"The minister kowtows to thank Your Majesty for your holy kindness." Xu Guochong realized that it was not good. He originally asked the Emperor to reduce the burden, but the result was that the Emperor personally took the field.

The Confucian scholars of the Imperial Academy actually didn't want to learn mathematics for another reason, that is: they didn't know whether the Emperor's mathematics was really good. The students of the Imperial Academy were working hard to calculate, is the Emperor's liking really liking?

Now it is a mule or a horse, it can be pulled out for a walk.

Zhu Yijun revealed a sunny and cheerful smile, signaling Xu Guochong that he could leave. Whether it could be explained clearly and understood, wouldn't it be known in the afternoon?

In the afternoon, after lunch, Zhu Yijun took a large pile of tails and headed to the Yilun Hall of the Imperial Academy.

The libationer of the Imperial Academy, Fan Yingqi, Sun Ying'ao, and others were ready for battle, carefully selecting ninety students whose grades were far ahead from the Mingli Hall and Side Hall to come to study.

Zhu Yijun appeared in the classroom. After everyone performed the grand ceremony, Zhu Yijun's little mathematics class began.

I know about the renaming of Zhang Juzheng's sons, just for the convenience of reading. Asking for monthly tickets, Aowu!!!!!
