Seeing that the concierge opened the side door, Zhu Ying quickly dragged Zhang Shou in. Ge Yong's face looked like the bottom of a pot.
"You've been denied entry twice, but this time it's even better. You sent a bunch of books directly in my name, and your beautiful words were loud and clear. Fortunately, I thought you were sincere and honest... I was so angry!"
Seeing that Ge Yong was furious, Zhang Shou saw a tall old man looking at him, so he stopped Zhu Ying who wanted to help explain, and raised his hand to Ge Yong and bowed deeply.
"Teacher, I sent books to those people outside in your name. Although I had a temporary intention, I also thought about it carefully."
As Zhang Shou spoke, he reiterated the reasons he had used to dissuade Zhu Ying from chasing people away. Seeing that Ge Yong's face softened slightly, he continued: "Even if this is just my guess, not all of these people may have arithmetic talent."
People, but as long as there are really a few of them like this, and I drive them away because I can't stand the slander for a moment, wouldn't it damage the teacher's reputation as a master of arithmetic?"
"Dozens of books are from the bookstore run by Lu Sanlang. The cost is very small, but if they fall into the hands of people with arithmetic talent, they may be a guiding light for them. As long as there are ten or eight, no, as long as there are three or five
If an individual can make the effort to truly study in depth, then he will not be alone in the arithmetic that the teacher pursues all his life!"
"This is indeed my own decision. Please forgive me, teacher!"
Zhang Shou kept calling him "teacher", and the reasons he gave were really touching. At least Ge Yong, who was just pretending to be angry, now felt so excited that he wanted to yell at his old friend.
Look at the big heart of an old man like me, a closed disciple! Even though I have been slandered by others, I am still so considerate of others!
What Ge Yong wanted to say was immediately snatched up by Zhu Ying: "Grandpa Ge, Grandpa Qi, I just wanted to drive away these troublemakers. I originally wanted people to block the streets on both sides to register names. Look back.
Report these people who violate the ban on travel documents to the emperor! It was Ah Shou who persuaded me. Now that I listen to him, I feel that it is fortunate that he is broad-minded and thoughtful..."
"Humph, who doesn't know what kind of temper you are, Xiao Yingying? He can persuade you, no one else can!" Ge Yong finally grabbed the step and walked down the stage. After snorting softly, he said to Zhang Shou in a friendly manner.
, "Take it easy in the future. As a teacher, I have a good temper. But if you were like Lao Qi and Lao Chu, if they knew you were causing chaos in their name, they would have to expel you from the school!"
Qi Jingshan, who had been silent all this time, finally stopped laughing, and then said in a tone like coaxing a child: "Okay, okay, you are great, and your disciples are also more powerful than mine. Is that okay?"
Before Ge Yong could blow his beard and glare, Qi Jingshan gently nodded to Zhang Shou and said, "Your response to today's farce was really good. I didn't expect that not only could you calm down the impulsive Yingying, but you could also
You can use such a gentle and gentle way to influence people's hearts. As for the incompatibility between the two, your teacher just curses you a few times, so you don't need to take it to heart."
Ge Yong opened his mouth and wanted to say that I was really angry just now, but thinking about the damage to his glorious image, he could only snort again and forcefully change the topic.
"Of course this boy has merits. My family is full of deaf and mute servants. When you and Old Chu's students first came here, they hesitated to speak. They looked suspicious and thought I had a conspiracy.
Huh, these are all the old chamberlains left behind by Emperor Ruizhong. The Queen Mother personally named them and brought them to me. They were all clamoring to die with them in the palace, so if I keep them, they can still use their remaining energy!"
Speaking of this, he raised his chin and shouted to Zhang Shou: "Since you are talking about...using arithmetic to design a password? Well, it sounds very novel and interesting. Come and explain it to my two old-fashioned people...
By the way, before I asked you about the book just now, a new book suddenly came out for me!"
Seeing that Ge Yong couldn't wait to pull Zhang Shou over, Zhu Ying was stunned for a moment, and then she couldn't help shouting angrily: "Grandpa Ge, Ah Shou is going to see my grandmother later. Don't do it just because you want to count something."
Hold him back!"
I think back then, Grandpa Ge dragged his disciple who was the Minister of the Ministry of Revenue all night in order to calculate a question, and he almost missed going to court!
"The ancients used to report emergency military situations. They initially used objects, such as a talisman that was a few inches long to represent something. It could express several to more than a dozen meanings at most. However, because sometimes specific information needed to be conveyed, later on,
Often a secret message is cut into three parts and sent by the courier."
"In the Tang Dynasty, words that could be broken into characters were often used to convey information. However, the splitting method has advantages and disadvantages because there are many forms of splitting. In the Song Dynasty, the Wu Jing always had a word test that specifically stipulated that,
During a war, specific verses can be used to convey more than forty kinds of military information."
In the study room of Ge Mansion, Zhang Shou took a thousand-character text and opened it casually.
"But now, if we add arithmetic, we use the Thousand-Character Script as a code book. Each character in the Thousand-Character Script gets a number in order, from one to one thousand. For example, we want to convey a message, Huang Mu's story
, then, we only need to find the numbers corresponding to these three words and write the numbers directly on the paper. This is a secret letter. Of course, this is the simplest..."
As Zhang Shou spoke, he smiled and wrote a random function f(x)=3x+1 on the paper.
"It's a little more difficult. We can use this mathematical formula to calculate the numbers corresponding to the three characters "Huang Mu Gu", then write the three characters corresponding to the new numbers on paper, and then send them by letter. In this way
Come on, as long as the other party knows the formula, he can easily and skillfully deduce the original text..."
Facing two people who are proficient in arithmetic - of course, Zhu Ying who was poking around can be ignored - Zhang Shou wrote a bunch of various functions from simple to complex on the paper with a smile, and then watched with great interest
Ge Yong immediately began to deduce and calculate. He didn't look like someone who was coming into contact with functions for the first time. He knew that the teacher had read the function book that was first listed at the beginning.
Not only Ge Yong, but also Mr. Qi next to him was equally familiar with calculations and interjections. He had clearly studied it. Zhang Shou couldn't help but sigh in his heart. For such a master of arithmetic, as long as he masters the principles, many things can be easily done.
comprehend by analogy.
However, when he saw Zhu Ying glaring at him angrily, clearly urging him to hurry up and not delay going to Zhao Guogong's mansion, Zhang Shou was afraid that Ge Yong would ask him about the origin of these books, so he smiled and said: "Teacher, I
It’s my first time in Beijing. I’m going to Yingying’s home to see Mrs. Tai soon, but it’s hard to find elegant things at the moment. I wonder if the teacher can give me a calligraphy painting?”
Ge Yong was diverging his thoughts there, wondering if the function he had just come into contact with a few days ago had other magical uses. At this time, he said impatiently without raising his head: "There are a lot of books on the desk over there, go and get them yourself!
It’s just calligraphy and painting, I can have as many as I want.”
Zhu Ying couldn't help laughing when she saw that Zhang Shou actually suggested the idea of giving a gift to her grandmother to Ge Yong. She was more direct than Zhang Shou, so she simply took Zhang Shou to the book desk over there and started searching.
A picture of rich peonies was shown, and she just felt that the more she looked at it, the more she liked it. She immediately tugged on the corner of Zhang Shou's clothes, and then poked the scroll in her hand.
Zhang Shou suddenly burst into laughter. This is for your grandmother, not for you! But thinking about how much the madam indulged Zhu Ying, he thought for a while and finally nodded: "Since you like it,
, just pick this one and tell the teacher."
"Come on, don't talk nonsense. If you want to follow Xiao Yingying back to see her grandmother, go quickly! If you don't have a place to live, you can stay here with me later..."
Before Ge Yong finished speaking, Zhu Ying dragged Zhang Shou out and shouted as he walked: "Grandpa Ge, don't worry about where Shou lives. There are plenty of guest rooms in the Zhao Guogong Mansion!"
Are you kidding? If Ge Yong drags Zhang Shou to study some problem, it might take ten days and a half!
