Liu Chang only thought that the name was very familiar, as if he had heard it somewhere.
But he didn't dare to ask any more questions.
He only knew that the teacher in front of him, who seemed very amiable and approachable, was a very knowledgeable person.
"Sir, have you ever learned to count?"
"You're looking down on me...well...you know a little bit."
"Okay, let me teach you this."
Liu Chang finally couldn't help it anymore, "Teacher, in terms of Confucian knowledge, I am indeed inferior to others, but in terms of numbers, I have never met an opponent so far!"
"Oh? You also like counting?"
Zhang Cang was very excited. He took Liu Chang's hand and hurriedly took out a few manuscripts from the books he carried. "Here, take a look at this. Can you understand it?"
Liu Chang read it carefully.
"Today there is a field of fifteen steps. From sixteen steps, how much is the field? The answer is: one acre."
"There are also twelve steps of Tian Guang. From fourteen steps, I ask how many steps the field is? The answer is: one hundred and sixty-eight steps."
"Isn't this just length and width? What's wrong with this?"
Liu Chang glanced at it for a few moments and then said proudly: "Teacher, you can ask whatever you want! If you can't answer, you will tear me apart!"
"Huh?" Zhang Cang was stunned for a moment, but still asked: "If Tian Guang takes fifteen steps, from twenty steps, what is Tian Guang's geometry?"
"Three hundred steps!"
"good!"
Zhang Cang's eyes were full of approval. Although this question was very simple, it was really amazing that Liu Chang could answer so quickly at his age. Next, he asked Liu Chang to continue reading. Liu Chang
Looking back, the next step is indeed division... extremely simple.
After that, there are fractions, proportional arithmetic, volume formulas, negative numbers and their addition and subtraction rules, as well as equations, and the Pythagorean theorem... Although they are not difficult, these things are all in the field of applied mathematics, differentiation and calculation.
, related to practical issues such as allocating land, buildings, and allocating grain.
Liu Chang looked more and more familiar, "Nine chapters of arithmetic?"
At this moment, Liu Chang finally remembered who the big boss in front of him was.
Zhang Cang... the fierce man who supplemented and improved "Nine Chapters of Arithmetic".
Liu Chang's talent in mathematics made Zhang Cang very excited. The two began to discuss mathematical issues, and the teaching turned into a debate. Liu Chang naturally would not let go of this good opportunity to show off, and said loudly
Looking at various mathematical formulas, Zhang Cang was stunned for a while.
"Wonderful! Wonderful!"
As Zhang Cang listened and memorized, his attitude towards Liu Chang also became closer and closer.
However, when the mathematical problems were linked to today's real-life problems, Liu Chang couldn't defeat Zhang Cang. Zhang Cang even comforted him that it was just because you didn't know much about the outside world. You still need to increase your knowledge so that you can learn more in the future.
, definitely far more than me!
Next, Zhang Cang asked about the textile machine again, and Liu Chang was surprised to find that this fierce man actually knew about machinery!!
When Liu Changru met his close friend, he was extremely happy. In this era, it was so rare to meet someone with whom he could discuss advanced mathematics, and also discuss physics and mechanics with him!
It could be seen that Zhang Cang was in the same situation. His formerly white and tender skin turned red at this moment. He became more and more excited as he talked, and the two of them almost hugged each other.
Liu Chang gradually let go of his guard against Zhang Cang and asked carelessly: "Master, besides mathematics and mechanics, what else do you like to do in your daily life?"
"I like to eat. I travel around to study, mainly for the different delicacies from different places!"
"me too!!"
Liu Chang held his hand excitedly.
"Of course, I also have to meet local beauties occasionally... Hahaha, different places produce different beauties!"
"me too!!"
The two quickly started to hook up, and the master and apprentice suddenly became close friends.
"Back then, I went to study in the Kingdom of Yan and stayed at a family's house. The man insisted on letting his concubine serve me..."
Zhang Cang said with a smile, his teacher's morality had long been forgotten by him.
If Liu Chang's ancestor saw them like this, he would probably jump out of the coffin and chop them with a sword.
"And then?"
........
"Mr. Zhang... is a naughty boy. I hope you can discipline him well."
Liu Bang said with a smile, Zhang Cang said seriously with a straight face: "Young Master is still very well-behaved, I will discipline him well."
Liu Bang likes Zhang Cang very much, not only because his teacher is named Xunzi, but also because of his extraordinary talent. Among all Xunzi's disciples, Han Fei and Li Si are famous, but this young disciple is always easy to
Forgotten.
Zhang Cang was from Yangwu. When he was young, he worshiped Xunzi as his teacher and studied his knowledge. During the Qin Dynasty, he served as the censor and was in charge of various documents and files in the palace. His biggest hobby every day was reading, which was more important than Gaigong's.
It was many years too early. Later, because of committing a crime, he fled back home.
When Liu Bang passed through Yangwu after conquering the city, Zhang Cang followed Pei Gong as a guest to attack Nanyang.
Later, Zhang Cang broke the law again, took off his clothes and leaned on the instrument of torture. His body was tall and big, and his skin was as plump and fair as gourd seeds. Wang Ling happened to see him and marveled at how good Zhang Cang was.
Therefore, Wang Ling interceded with Liu Bang and pardoned his death penalty. This once again proved the importance of appearance. As for what crime Zhang Cang committed, well, it's hard to say. It was not a serious crime anyway.
Later, Zhang Cang was promoted to be the Prime Minister in charge of financial management. Historically, he served as Liu Chang's Huainan Prime Minister, and finally became the Prime Minister to his fourth brother.
What talents does Zhang Cang have? The measures, weights, measures, and calendars of the Han Empire were all designed and perfected by this person. This set of things has been used for many years. He was the first person in China to directly apply the results of arithmetic research to the national economy and people's livelihood.
's Prime Minister.
At the same time, this person has some attainments in law, music, classics, mechanics, etc.
The only fly in the ointment is that this person has two bad habits...the first is gluttony, and the second is lust.
Therefore, the most powerful one was Xunzi. He taught a few disciples casually, two of them became fortune tellers, and one became a saint.
Liu Chang loves this master to death, not only because they have the same interests and hobbies, but most importantly, he can take him out to play.
That's right, Zhang Cang directly thought that the young master had gained more knowledge and left the palace with Liu Chang. Liu Bang and Empress Lu did not stop them at all. In their opinion, Liu Chang had become honest and well-behaved since Zhang Cang arrived.
It can be seen that this is a trustworthy Taifu.
When they left the palace by car, Luan Bu was waiting outside.
Luan Bu saw Zhang Cang clearly on the carriage and suddenly leaned down to bow to him.
Zhang Cang let him stand up with a smile, and then looked at Liu Chang.
"Chief, I'm going to take a walk around the city... After I'm done, I'll pick you up at the Zhou Mansion!"
"Master, why don't you take me to play?"
"Hey, you are still young. When you are older...I will take you there."
"Okay, then I'm going!"
"Chief, if your friend's parents don't want to see you, just call me and I'll help you persuade... By the way, sneak some wine for me... I'll give you a sip when the time comes... I'll give it to you
You bring some delicious food..."
Luan Bu on the side was stunned. At that moment, the image of the Confucian sage seemed to collapse in his heart.
"Mr. Zhang...Young master is young and cannot drink alcohol..."
Before Luan Bu could finish speaking, Zhang Cang had already disappeared in the car without a trace.
Luan Bu followed Liu Chang with a complex expression. Liu Chang was smiling and praising how good this master was, but Luan Bu hesitated.
"Luan Bu, I have never seen you so afraid of a person. Why are you so afraid of Master? Don't be afraid, the rumors outside are all false! Master is not a cruel person at all!"
Luan Bu said: "The reason why I respect Zhang Gong is not because he is a person, but because of his knowledge. The reason why I fear Zhang Gong is not because he is afraid of his power, but because he is a teacher."
"Oh...he still has a master? Who is his master?"
"Xunzi."
Liu Chang suddenly stopped, turned around blankly, and stared at Luan Bu, "Who?"
"Xunzi."
In the Zhou Mansion, Liu Chang smiled stupidly and said loudly: "My master was so great back then that he could be called a saint. Do you know who my master is? My master is Xunzi! Also, Han Feizi is
My uncle! Li Si too! Hahaha, now that I have obtained their true biography, and my master knows it, I must be extremely happy!"
"I have decided to inherit the legacy of my ancestor! Carry forward our Confucian lineage! I want to become the new sage of Confucianism!"
"Your Majesty...didn't you treat Huang Lao before? You also told us that Confucianism copied Huang Lao..."
"Fart! It's obviously Mr. Huang who copied our Confucianism!"
"I am a disciple of Xunzi! How can I be related to Mr. Huang?"
"However, Mr. Gai is also kind to me..." Liu Chang touched his chin, pondered for a moment, and said, "Forget it, I'll just try to be a saint of two schools of thought!"
