Weird Three Kingdoms

Chapter 37 New Troubles
Liu Hong couldn't believe it. You Fei Qian was so young, how could you possibly know this thing?Besides, I just made this one, how could Fei Qian know?Is there really such a thing as a naturally intelligent person?
Fei Qian looked at the "abacus", and finally understood why there was always an awkward sense of familiarity. Familiarity was because he had learned this arithmetic method when he was in elementary school. The awkwardness was that the abacus was holding beads one by one. Put it in the grid in the middle, not with a stick in the middle of the beads to move it up and down.

"Why don't you use wooden sticks to string them together?" Fei Qian thought so, and said it casually.

"What kind of stick?" Liu Hong, who was beside him, asked Fei Qiandao in confusion.Could it be that my abacus, which took so much effort to come up with, is still lacking?
"This..." Fei Qian hesitated, shouldn't I order some strange technology tree to come out?
When was the ancient Chinese abacus finalized?Tang Dynasty or earlier?Anyway, it must have been in the Song Dynasty. I remember that in the painting of Shanghe during the Qingming Festival, there are abacuses placed on the counters of shops, and the form is basically no different from modern times.

Now put this abacus out, it shouldn't have any effect, right?Fei Qian thought to himself, but he had already said it himself, and it was not easy to take it back, so he simply asked for a piece of paper and drew the abacus of later generations in three strokes.

Liu Hong waited for Fei Qian to finish painting, grabbed it before Cai Yong, nodded, and praised, "Yeah, why didn't I think of it... In this way, I'm not afraid of losing it, and besides The pearl of the same pillar, the heaven and the earth are added to the human being, tsk tsk... Wonderful! Wonderful!"

"Heaven and earth add to man" actually means that the top row of beads is called dzi beads, and the bottom beads are called earth beads. When calculating, it is the combination of dzi beads and earth beads, which coincides with the three talents of heaven, earth and human beings.

However, Liu Hong also found something he didn't understand. He pointed to the abacus drawn by Fei Qian and said, "Why do you want to increase the number of dzi beads to two or five?" ——If modern abacus uses decimal system, in fact, the top one and the The bottom one was not used, but Fei Qian didn't think much about it and drew it directly in the form of a modern abacus.

Fei Qian didn't know why the modern abacus added these two unused beads, so he said: "The lower bead is five into one, and the upper bead is two, so it's convenient to calculate."

"Five into one for the next pearl, two for the upper pearl..." Liu Hong nodded and shook his head after hearing this. Fei Qian did not know whether Liu Hong agreed with him or disagreed.

In fact, Fei Qian is not a professional after all, and he does not know the development history of abacus, so naturally he does not know the evolution of abacus.

During the development of abacus, it has gradually spread from a small number of people who study mathematics to people who need to deal with a large number of numbers, and a large part of them are merchants. Moreover, in ancient times, there were not only decimal calculation modes, but also hexadecimal calculation modes. For example, in ancient times, one catty was 16 taels, etc. Therefore, for the convenience of calculating the hexadecimal system, merchants added one piece of heaven and earth pearls to the ancient abacus, so that the sum of heaven and earth pearls equals fifteen, which happens to be used for Decimal can also be used for hexadecimal.

Liu Hong stared at Fei Qian with bright eyes. If he originally wanted to accept Fei Qian as his apprentice and just said it casually, now he really has this thought.This son is good at calculating the scriptures, and in just a few moments, he has improved the abacus that I have figured out for so long. Alas, how could he be robbed by old man Cai?
Cai Yong also saw something on the side, pondered for a while, and simply said: "Ziyuan is a new harvest for me, although I have already started, but it is not an auspicious day, it coincides with the autumn class of Taixue tomorrow. If Yuan Zhuo has time, can he watch the ceremony?"

In the Han Dynasty, Taixue generally recruited a group of freshmen in the spring and autumn, the so-called spring classes and autumn classes.In the past, the Taixue was closed for a period of time due to the disaster of the party. Later, Emperor Ling of the Han Dynasty reinstated the party, and naturally the Taixue was reopened.

Liu Hong looked at Cai Yong, nodded, sighed, and immediately said, "Of course he's coming." - Now there is no hope at all, this kid is Cai Yong's, and he can't get it. But, hehe-

Seeing that Liu Hong agreed, Cai Yong didn't say anything else, and explained that Fei Qian could go to prepare, and let Fei Qian go back first tomorrow.

After Fei Qian left the Cai Mansion, he still felt a little unconvinced. After only a few days of work, he seemed to have upgraded himself?

Cai Yong just now said that he would go back and prepare, what should he prepare?Naturally, it was the ceremony of apprenticeship, which meant that Fei Qian would get rid of the word "registered name" and become Cai Yong's true disciple as long as he had the apprenticeship ceremony in Taixue tomorrow.

This is really happiness not to come suddenly...

However, Feiqian suddenly thought of a question, and he couldn't help but get a head start. Originally, he planned to leave Luoyang on the grounds of going to Jingxiang to study in a few days, but now he was accepted as a disciple by Cai Yong. Then how can I leave Luoyang?

If you can't leave, how can you save your own life in this turmoil?
It's really a plan that never catches up with change, how can this be good?
******************
In fact, there are far more people who are troubled than Fei Qian.

Yuan Wei was one of them. He was also very troubled after Yuan Shao resigned and left.

Yuan Shao's departure was no less than bringing to light the struggle between the Yuan family's descendants.In fact, this matter is inevitable for every noble family, but most of them are silently digested within the family, and few people in the world know about Yuan Shao's actions.

And the most important point is that it has also been used by people.

Dong Zhuo's personal husband actually named that renegade prefect of Bohai!This shows that the two sons of the Yuan family are going to compete, but unfortunately, Yuan Wei can't say a word.

On the surface, the Yuan family has always been the most important thing in the world, and it is a slogan of Qingliu. Now Dong Zhuo, in the name of the imperial court, said that although Yuan Shao had minor faults, he was still available. Therefore, he worshipped the prefect of Bohai to protect the good people, eliminate bandit troubles, and make up for his faults. ...

Everything was blocked, what else could Yuan Hui say?Don't let Yuan Shao be the prefect?The reason?Is it because the children of the Yuan family are incompetent?Do you not want to serve the court?Or not let it make up for it?Or do you want to immediately put down a search order and hunt for thousands of miles?

Although Yuan Wei really wanted Dong Zhuo to pursue a thousand miles to kill him, but the laws of the Han Dynasty stipulated that relatives are reasonable and legal to hide from each other. Could it be that Yuan Hui could carry out the law of the Han Dynasty and really kill his relatives?

This righteous annihilation of relatives is really not a good word in the Han Dynasty. Is the reputation of the Yuan family still needed?So Yuan Wei had no choice but to pinch his nose.

But just letting Dong Zhuo and Li Ru mix sand into Yuan's house like this, Yuan Wei was unwilling to think about it, so he ordered his servants to call Yuan Shu.

Since it is no longer possible to hide it, just put it on the table dignifiedly!Let everyone in the world see the spirit of the Yuan family of my fourth and third princes!
