Yesterday, he irresponsibly left the one-variable equation to Lu Sanlang to teach. On this afternoon, Zhang Shou directly threw out the two-variable linear equation. With such rapid progress, he will be sprayed to death by countless educationists in future generations.
, but now facing a group of students who are at least sixteen years old and up to nearly forty years old, he has no burden at all.
They are all adults who have been baptized by the nine chapters of arithmetic. I will spend half a day telling you what primary school students have mastered in half a month. If you can't understand it, you are stupid!
However, he did not simply talk about theory, but put chickens and rabbits in the same cage. The long rope used by Wang Jie in the Shuntian Mansion test last time to measure the depth of a well, and various problems such as the bowl of Zhi Monk were used as examples to fully demonstrate
It shows students the flexible application of linear equations of two variables in practical problems.
Sure enough, when these students discovered that as long as they made equations, various problems that were once considered difficult were so easy to solve, they were all very excited. However, when Zhang Shou was about to end the two classes, he suddenly assigned a completely unrelated topic
homework.
"There may be some of you who are not familiar with the Four Books and Five Classics, but you should have read all the Thousand-Character Essays on Enlightenment, and you should have read a lot of Tang poetry, Song poetry, and Chinese music. After you go back, recall what you have learned and see what
The sentences in the poems and songs are all taken from the thousand-character essay and then written out. This assignment is limited to five days, and you can hand it in at any time within five days."
The other supervisors only thought that Zhang Shou was doing it on a whim, and the purpose was to let them review the poems and songs while practicing sutra calculation, but Lu Sanlang didn't think so at all.
Zhang Shou did not tell him the purpose of Zhang Kang's invitation the night before yesterday, but he and Zhang Kang had known each other for a long time. Ever since he was praised by the emperor for his arithmetic talent after returning to Beijing, Zhang Kang asked him to try to open the secret box.
As a result, Lu Sanlang failed of course. He didn't even have any clues or clues, so he was a ghost...
So when he followed Zhang Shou back to his dormitory, he couldn't help but curiously asked: "Does the young gentleman already have a clue about the fourteen-ring key?"
"Oh, have you tried it too?" Zhang Shouxiao asked. When Lu Sanlang said awkwardly that he had no clue, he shrugged and said, "I don't have any clues. It's just a dead horse treating a living horse. Let's try it first.
The thousand words in the Thousand Character Essay can be combined into how many famous poems and lines from previous generations. Then use the same algorithm that Wang Dayin asked me to decipher the secret letter to try my luck."
At this point, he shrugged and said, "If it works, it's fine. If it doesn't, there's nothing I can do about it."
Lu Sanlang was stunned for a moment, then clapped his thigh and said: "Why didn't I expect that this is indeed a solution! Young sir, you should have told me earlier to see which poems have words from the Thousand Character Classic. Uncle Weinan has already done this
I had someone do it, but because it didn’t match the fifty-six words, I gave it up. Just wait, I’ll go to his place and get you a copy of those verses!”
Seeing that Lu Sanlang was about to run away after saying these words, Zhang Shou's heart moved and he suddenly reached out and grabbed his shoulders.
The total number of Chinese characters is tens of thousands, and the commonly used Chinese characters, later statistics are 3,500, but statistics say that 98% of daily data are the most commonly used 1,000 characters, and 99%
It is a commonly used 2500 words.
The Thousand-Character Essay also contains a thousand characters, but there are many rare characters in it, and the coverage is not so wide. You can find dozens or even hundreds of lines from ancient and modern poems, and it should be no problem. Of course, in the Thousand-Character Essay,
Rushuang, Ruo, Dan, Ya, Bei, Yan and other commonly used words in poems and songs are not included, which will definitely reduce the number of poems that meet the requirements.
But no matter what, if students like him are asked to sort out which poems are completely written in the Thousand Character Classic, even if they rack their brains, they will naturally not be able to compare with Weinan Bo Zhang Kang's pursuit of the secret.
The people of Secret Box have made unremitting efforts for decades. However, Jiuzhangtang has many people and great strength, so it may not be impossible to do this.
Such thoughts flashed through his mind. When Zhang Shou saw Lu Sanlang looking at him in confusion, he smiled.
"Since you are going to see Uncle Weinan, then ask him for me whether the matter he asked me to do can be regarded as a topic and provided to the students of Jiuzhangtang. My ability alone is limited, Teacher Ge and others
I can't do anything that the grandmaster can't do, but if there are more people involved, I might have some ideas."
Lu Sanlang opened his mouth, originally wanting to ask those students who had to work hard to understand and understand equations, how they could help Zhang Shou, but in an instant, he understood what Zhang Shou meant.
If nothing else, these people might be able to find poems that Zhang Kang had not discovered before; what's more, which words in these poems correspond to the words in the Thousand-Character Classic would also require manual sorting, and he would not be happy to do so.
Count them one by one! Of course, the most important thing is that even the stupidest people may sometimes have an idea and find an idea that smart people have not thought of.
Of course, the premise is that the secret text is really related to the fourteen-character poem and song, rather than a random sentence...
He immediately held his head high and said: "I understand, let's go now! Don't worry, young gentleman, if Uncle Weinan doesn't agree, we can just fool him casually. Anyway, this is the matter of his Arms Bureau, and it has nothing to do with us.
Irrelevant!”
Of course Zhang Shou praised Lu Sanlang's vigorous and resolute approach, nodded and motioned for people to go quickly. An hour later, he saw Lu Sanlang excitedly pushing the door in and handing over a dozen pieces of paper.
"I said, go to Uncle Weinan and ask for these things. He must have them. After he discovered that all the characters in the Fourteen Rings came from the Thousand Character Text, he urgently ordered his thirty or forty cronies to go through the poetry collection to find the verses.
It took more than half a month! Of course, I can’t say that there are no omissions, but I should have looked for all the famous poetry collections, and I haven’t had time to figure out the next step.”
"Also, Mr. Weinan, you said before that you should consider this as a topic. Uncle Weinan also considered it carefully. He was a little hesitant at first, but after thinking about it, he seemed to have figured it out and said he was willing to give it a try. Anyway, that
Once the box is opened, it is said that a new key can be reset, so there is no need to worry about it not being able to be used in the future.”
That box actually has the function of resetting the password? It’s quite advanced!
Zhang Shou thought so in his heart that he had to take the paper and start reading. With just one scan, he discovered that it was probably because it was not easy to find poems with all fourteen characters from the Thousand Character Classic, so he settled for the next best thing.
All poems and songs that match the seven characters are included.
For example, the water of the Yellow River comes up from the sky. The first character Ben in the next sentence is not included in Qianziwen, and the next sentence is not included.
For example, in ancient times, everything flows eastward, and the same goes for enjoying the worldly pleasures in the previous sentence. If the second word "jian" is missing, the previous sentence is not included.
For example, in the sentence "May the moonlight shine on you", the word "wang" does not appear in the previous sentence, and the previous sentence does not include the word "wang".
Looking at the poems on those pieces of paper, there are very few that match all fourteen words. Even five-character poems, or those poems and poems whose number of words are not as strictly corresponding as quatrains and rhymed poems, are quite a lot. Obviously Zhang Kang's
People often use their brains and work hard.
Lu Sanlang was still explaining beside him: "As for the fifty-six characters on the lock, none of them can form a poem."
Zhang Shou nodded, and after reading it briefly, he said to Lu Sanlang: "Tomorrow morning, go to Jiuzhang Hall and see if anyone has submitted homework. If the poems are different from the ones above, they will be included. If they are the same, they will not be used.
Trouble. Then, you said that this was to help the Ordnance Bureau solve a problem, and asked them to extract the number represented by each word in these poems in the Thousand-Character Classic..."
Lu Sanlang nodded while listening, and finally went out with great energy. However, Lu Sanlang, the smartest man, did not eat alone. Now he, the chief of the team, is responsible for presiding over the morning classes, while Qi Liang is responsible for doing the morning classes in his free time.
He talked to people one by one to understand his personal situation and character. So of course he would not leave Qi Liang behind for such a big task.
As for Zhang Shou himself, after Lu Sanlang left, he spread out the paper on his desk, patiently replaced the fifty-six characters on the fourteen-ring text code lock with the corresponding numbers, and then thoughtfully used
Fingers tapping nails.
"Instead of simply plugging it into the calculation, why not talk about the function? If it is a linear function, then draw a plane rectangular coordinate system and plug in the numbers before and after? In this way, you can also talk about analytical geometry at a glance... Well, it is more advanced.
It's a waste of paper..."
When Zhang Shou was about to use the many manpower in Jiuzhang Hall to start a decryption battle, Weinan Bo Zhang Kang's urgent report was also sent to the emperor's desk. For the man who had lost the key since the reign of the late Emperor Ruizong, he was
The emperor was not as persistent as Zhang Kang, but he was still curious, so he was not annoyed with Zhang Kang's approach of killing first and telling the story later.
"Jiuzhangtang has only been in class for a few days, and Zhang Shou actually used Zhang Kang's request for his help to create a big problem. This guy is interesting." The emperor stood up and said to Chu Kuan that he had sent him a lesson.
The big cloak turned a blind eye and walked around the room with his hands clasped in his hands. "I heard that the second brother went to see Zhang Kang? Does he know about this?"
"You should...don't know, right?" Chu Kuan tried his best to make his answer appear uncertain, and then said cautiously, "After all, the second prince is the uncle Weinan who went to meet the uncle Weinan the day before yesterday morning. He met the uncle Weinan twice before.
Meeting Zhang Shou, and the time Lu Sanlang went to see him today happened to be at a wrong time..."
"Okay, no need to say more." The emperor interrupted Chu Kuan and said lazily, "The boss and the second child have been fighting since they were young. Now that they are older, it is not surprising that the boss has other thoughts.
At least he knows how to be a little more restrained, and if he is looking for someone like Zhang Chuan, the Duke of Qin, who is studying and studying without being concerned about state affairs, then he dares to directly reach out to the Arms Bureau."
Chu Kuan originally wanted to say that they probably also wanted to show you your talents, but when he saw the emperor's sneer face as he spoke, he did not dare to say any more. Especially when he saw the emperor suddenly striding out, he originally planned to serve the emperor. He quickly chased after the empress dowager who was unconscious at the Qingning Palace. He caught up with the emperor in front of the main hall and put on the thick fox fur cloak on him.
"You are the Chief of Ceremonies, Bingbi, and you are no longer a steward of the Qing Palace. You don't need to hang around me all day long." The emperor said these words without looking back. Chu Kuan was in a dilemma because of this, but he watched the emperor go. After walking for more than ten steps, he finally caught up with me again.
Sure enough, the emperor never asked him to leave again, even after entering Qingning Palace. When he saw the emperor bowing somewhat nonchalantly and saying good night to the Queen Mother, and was about to leave after sitting for a while, he just relaxed. However, the emperor who had just left his seat suddenly asked two questions with a half-smile.
"I heard that the queen mother praised Zhang Shou in front of the eldest son and the second son? Is it interesting?"
