Weird Three Kingdoms

Chapter 36 Liu Hong's Showing Off

Who is Liu Hong?

The leader of the academic world, who is tied for the first place with Cai Yong, actually said that he wanted to accept him as his apprentice. It was like a huge pie suddenly fell from the sky and hit him in front of him.

Fei Qian just opened his mouth subconsciously, and then closed it quickly, um, why does this scene feel a little familiar?Later generations seem to have encountered such a situation in the leadership's office - it happened that the head of another department came to do things, and it happened that you did it smoothly, praised you for your ability, and asked if you want to go to my place to do it...

If you agree, then everyone will have a meal, and then you can only laugh...

Moreover, this was still in the Han Dynasty, a dynasty that attached great importance to the inheritance of teachers.The earlier the age, the more emphasis is placed on the teacher's inheritance. Unlike modern times, everyone has experienced countless teachers from childhood to adulthood, such as primary school teachers, middle school teachers, university teachers, language teachers, mathematics teachers, etc., not counting those sports. Music or some kind of substitute teacher, so for modern people, there are too many teachers, so there is not much feeling. On the contrary, in ancient times, a person may have one or two teachers in his life. , this difference leads to different levels of emphasis on teachers.

"Almost fell into the pit," Fei Qian slandered, "Liu Hong looks handsome, but I didn't expect to dig such a big pit for me..."

So Fei Qian bowed his hands as a gift and said, "The boy thanked everyone Liu for their love, but the boy has already been taught."

Liu Hong actually didn't want to dig a hole for Fei Qian, but he was a little excited just now, so he said it casually, but as soon as he blurted it out, he regretted it. Fortunately, Fei Qian did not agree, otherwise it would be really difficult.

Seeing Fei Qian say this, Liu Hong also just pretended to be stupid, "Oh, I don't know where the teacher is?"

At this time, Cai Yong coughed twice - Okay, you Liu Hongmo has acted, and I just told you that Fei Qian is a registered disciple I accepted, or did I call you over and you said that I will inherit from my teacher?
You think Fei Qian is good, I think so too, so don't think about it.Before Feiqian could answer, Cai Yong said, "Ziyuan was recommended to me by an old friend. It was a fate, so I accepted it as a disciple." - This time, Cai Yong deliberately omitted two words and upgraded from a named disciple to a student. disciple.

If no one robs it, I don't think so. If someone robs, Cai Yong feels that Fei Qian is actually pretty good. Although he is not as handsome as me, he is still handsome. Coming out can actually impress this old guy Liu Hong——In this way, Liu Hong used to show off how strong his maths is, and now my disciples have something better than him, this kind of feeling is not too good...

As long as it is a human being, there is a little bit of careful thinking. People from ancient times and today are the same.

Liu Hong suddenly patted his forehead and said to Cai Yong, "Ah, I almost forgot, I'm going to bid you farewell this time. I'll be leaving Luoyang soon!"

"Why? It's not long since I came back, what's going on?" Cai Yong felt very surprised.

Liu Hong said: "Hong Bucai, moved to the prefect of Shanyang County, no, the seals have already been sent." After speaking, he took out the seals of the prefect from his arms and showed it to Cai Yong.

The prefect of the county is also a local officer with more than two thousand stones. Although Shanyang County is not a big county, it is not bad. Cai Yong was relieved and asked, "So, when will you leave, wait for me to give it to you? practice."

"Okay, let's stay for a few days." Liu Hong was not polite and agreed, and then took out a square wooden box that was slightly larger than a slap from his arms and gave it to Cai Yong, "Come here. Come and have a look." The tone of his voice was quite like that of cherishing the treasure and giving Cai Yong a long experience.

Cai Yong took a look and saw that the wooden box was made of ebony, and the outside was painted with a layer of paint.

Under Liu Hong's gesture, Cai Yong opened the box and saw that the inside of the box is divided into three horizontal layers, the top layer is the smallest, and the middle and bottom layers are larger. The box is divided into nine vertical columns, which form ninety small grids together with the horizontal laminates, and there are circles of corresponding colors between each small grid of the black and red laminates. There are 36 wooden beads, [-] black beads and [-] red beads, but the white laminate grid in the middle of the box is empty.

"What is this?" Cai Yong frowned. Although this box is not clear what it is for, it still has a sense of familiarity for some reason.

Liu Hong stroked his beard proudly, and looked at Cai Yong's thoughtful look with enjoyment--I'm so fortunate and took so much thought to come up with a wonderful thing, how could you guess it in a short time?

Fei Qian looked at it, and also felt that he had seen this form somewhere, and was also guessing what Liu Hong was used for - but what is certain is that this thing must be related to mathematics, and a character like Liu Hong is definitely not. It will be so boring that any toy will be offered as a treasure.

While thinking about it, Cai Yong picked up a black bead from the top grid and placed it in the middle of the grid in the white paint area. He looked left and right, but he still couldn't guess it. Then he took another red bead and put it in the white paint. in the grid...

Fei turned his attention with great concentration, black beads and red beads, layered up and down, and placed in the middle... This kind of pattern seems to be very similar to something?Fei Qian had a flash of inspiration and blurted out: "Abacus!"

Liu Hong, who was stroking his beard proudly and carefreely, was startled when he heard the words. He couldn't help but use more strength. He even pulled off two beards. He turned his head and asked Feiqian, "How do you know?!"

"Abacus?" Cai Yong murmured and followed, and immediately realized that this was not a long abacus changed into beads, and then placed in a box like a disk, "Haha, so, it's just an abacus, I guessed it a long time ago..."—Of course, he was still trying to keep his face, but he was really admired by Liu Hong's whimsy.

In the Han Dynasty, most people were still counting and calculating with alchemy. In ancient times, the so-called "choice" of strategizing refers to alchemy.

The counting chip is actually a small wooden stick. According to personal habits, it can be divided into two counting modes. One is horizontal counting, and the other is vertical counting. It is very complicated to say, but it is actually the one that represents the number "one". Whether the chips are placed horizontally or vertically.

However, after all, there are inherent flaws in the calculation, such as inconvenience to carry, easy to lose, accidentally mixed up in the middle of the calculation, and there may be times when you stop to do something in the middle of the calculation, and forget yourself when you come back. Is it calculated by horizontal stack or vertical stack, and in the end, I had to start all over again...

Liu Hong himself is a master of arithmetic, and he is very troubled by these problems. Therefore, he pondered over and over again and invented this tool, which simplified the arithmetic of each root into beads. The red beads represent one, the black beads represent five, and the white beads The area is used for calculation, each column represents a single digit, and the total of nine columns can be calculated to the level of hundreds of millions, which can meet the needs of counting to the greatest extent.

For the first time today, I took out the finished product and showed it to Cai Yong. I didn't expect that Cai Yong could not recognize it. Instead, Fei Qian, who was beside him, revealed the secret. How could Liu Hong not be surprised?
　Liu Hong was revered as a saint in later generations, and it is inseparable from the abacus he invented. Unfortunately, such characters are basically not mentioned in Romance of the Three Kingdoms... After all, Romance is for... If you are interested, you can pick up Du Niang's clothes... It's not easy for a newcomer, ask for a recommendation ticket and ask for a collection...
