The days when I pretended to be a cat in the Forbidden City[Comprehensive]

According to the latest regulations of the Qin State, all departments have to set aside a holiday every two days to give lectures at the Xianyang Academy of the Qin State.

In the beginning, the birth of this system was not aimed at ordinary students, but small officials in various departments. In recent years, there have been many reforms among various departments in Qin State. It is difficult to explain them in words, and the explanations one by one are too complicated. It is most efficient to get together to do it at one time, and in this way, the links of various departments can be finalized. Yes, this kind of lecture is actually vocational training at first.

The reason why I borrowed the place from the Academy is because the lecture hall of the Academy has a sound amplification effect, so I don't have to shout at my throat.

But later everyone discovered that the students of the Academy were very curious about the operating mode of Qin officials and the latest policies, which showed that there were often eavesdroppers at the door...

Officials who can give lectures are basically of a certain age. When people reach a certain age, they like students who are eager to learn the most. Like opening a gate, it is impossible to close the gate again.

Under the help of Xun Qing, vocational training has gradually developed into the current situation of giving lectures. Once every two months is not too much of a burden for a department. There are so many people in a department. There is less than one turn every year.

It is human instinct to be happy to be a teacher. Judging from the current situation, the petty officials are very keen to participate in teaching.For the students, it is naturally an excellent learning opportunity for them to be able to get in touch with Qin's central system and understand its functions at the beginning.

When you go to give lectures, you can talk freely. You can talk about the methods you found and the problems you encountered when you were working, and talk about the latest new policies of your department. Advertising is also possible.

But no matter how casual the content of the class is, there are only a few people like Lu An who move out a huge wooden plate and put it in front of the class before class.

Lu An is the official history of the state of Qin, two thousand stones, is regarded as the senior central management of the state of Qin, it is logical that such things as giving lectures should not be his turn, after all, he is also considered a big boss, how can a big boss easily appearance?Otherwise, it would be embarrassing for other department bosses.This can be regarded as a science in officialdom.

Therefore, on the day after the news that he was going to give a lecture was leaked, the people who were going to attend the lecture in the academy were overwhelmed, and the whole classroom was full. Just go and do it.

Not only the students from the Academy came to attend the class, Lu An also saw several colleagues and all the staff of Zhi Su Nai Shi.Lu An was speechless, and asked them what was going on before the class started, and got a series of honest smiles.

If the immediate boss wants to give a lecture, how can he not come to join him?

Nonsense!Lu An frowned, and drove all these people away. He came to scout for talents. It was a waste for these people to sit here. Maybe he missed the talents he wanted because of them. How could this be possible!If you have time to engage in formalism, it is better to go back and have a good rest. Everyone thinks that their department is abusing labor!

He also drove away a few people whose faces were familiar at first glance, and he saw two familiar people who couldn't be more familiar, and stared at each other twice. After getting a flattering smile, Lu An couldn't help it , he raised his hand and knocked on the small gong on the desk case, signaling the start of class.

Teachers and students greeted each other, Lu An glanced at the crowded classroom and said, "My name is Lu An, and I am your senior brother. You can call me Lu senior brother."

After the simple opening remarks, he went straight to the topic, "Today, I will introduce a brand-new calculation object to you. This object is called the abacus, which is a brand-new arithmetic method. Easier."

"In this class, I only teach the method of using this thing, regardless of political affairs, if you are not interested in it, you can leave first, don't waste your time."

After he finished speaking, he found that the eyes of the people in the classroom became brighter, and no one left at all. Lu An sighed a little in his heart, and glanced at Ying Zheng and his wife who were sitting still. He stood on the wooden plate Start teaching in front of you.

The principle of the abacus is the same as that of counting chips. The counting chip uses horizontal sticks to represent five, and four vertical sticks represent one.

And the abacus has one bead on the beam and four beads on the bottom, the upper bead is five, and the bottom four represent one each, and also every nine enters one.

Because the principles are the same and easy to understand, Lu An only gave a rough introduction, and then began to demonstrate how to use the abacus to perform addition and subtraction operations. He fiddled with the beads while talking about the formulas of the abacus.

At this moment, the classroom has been divided into two groups of people. One group of people stared intently at the big abacus in Lu An's hands with golden eyes, and the other group lowered their eyes and began to support it. When it reached one hundred, he stopped after decreasing to one one by one.

After dialing the last bead to put it back in place, Lu An said: "Addition and subtraction with an abacus is very simple. The principle is the same as that of counting chips, but it can save a lot of time. I have put the formulas in the learning table. Palace, you can copy and print by yourself.”

In addition to the functions of the school, Qin Guoxue Palace also undertakes the work of consulting and dissemination. There are often various wooden and slate boards placed at the entrance of the school, and various contents are engraved on them. Anyone who comes to Qin Guoxue Palace can spend a small amount of money here. You can buy a copy of Qin paper for a little money and print it yourself. If you are reluctant to pay, you can also copy it yourself.

However, due to the low price of Qin paper purchased here, those who can come here to seek scholars can basically afford the cost. Few people will copy it, but some people come here to read the inscriptions and practice calligraphy.

Because of the low cost, these various teaching materials rubbed from the Qin State Academy flew to surrounding countries as if they had wings, and there were even special businessmen to undertake the rubbing business, forcing the Academy to finally It has to be stipulated that one person can only print two copies to curb scalpers.

Most of these inscriptions come from the ancient books collected by the Qin State’s royal family, and there are also teaching materials and endorsements compiled by the gentlemen of the Academy. For the latter, the Qin Academy paid for it.Of course, there are also people like Lu An who take some private information for printing, but he needs to pay a certain amount of ink in advance, and he has to go through the content review, and the academy will not pay any fees.

"In addition, I will also put the formulas of multiplication and division together. If you are interested, you can preview them first. Next week, I will explain how to use an abacus to calculate multiplication and division."

"Now you can come up and try this abacus."

After he finished speaking, he stood aside and gave up his seat in front of the podium. Almost at the same time as he stepped aside, several students ran up holding the notes they had just recorded, saluted him and ran away On the edge of the big abacus.

Lu An took a few steps back, stood aside and watched them recite the mantra and fiddle with the beads. He didn't need to correct him, and the students who came forward together would argue with each other.

Although only one person started, the fingers of the bystanders couldn't help but flick up and down. In less than a stick of incense, these people around were able to perform addition operations normally, and they could even start to act like Lu An. I just tried to add one to one hundred.

This is the case with abacus calculation. It is very easy to start with simple addition and subtraction as long as you master the tricks. In the lives of ordinary people, addition and subtraction are enough to meet most of the needs of life.

But if necessary, you can use the abacus to perform more complex calculations, such as square root and power, which is a simple calculation tool.

The biggest advantage of abacus calculation is that it is small in size, and an abacus is enough for most of the calculations, and the number of columns can be increased if necessary.However, if you use the counting chip as a tool, you need to place the counting chip corresponding to each number on the table, and then add or subtract. The error rate is high and the labor load is also very large.

If this calculation tool is popularized, then the calculation accuracy and time-consuming can be improved to the next level, and maybe it can also cultivate talents who are good at abacus and mental arithmetic, then he can get rid of the endless overtime life!

Thinking of this, Lu An looked at the batch after batch of students who went up to play with the abacus and smiled very kindly. In his eyes, these are the vitality of the future.

"Brother." Just as Lu An's eyes were narrowed, His Royal Highness King Qin, who came out to take a class with his daughter-in-law disguised as a man, quietly walked over, completely ignoring his elder brother's stare and asked very naturally: "Is this Mr. Brother’s new technology? Do you want to promote it?”

Lu An had nothing to do with him, and said in a low voice: "I didn't create it, promote it... don't force it to promote it, let it spread naturally, just a little push from the official."

In the past few years, the Qin State has repeatedly sent troops, and now many states and counties that have been captured have not sincerely surrendered, and forced promotion will easily arouse their resistance.Things are easy to use and easy to learn. If the official mentions a few words, there will naturally be people who are interested in learning. In this era, no one will struggle with knowledge.

And now that Qin State has become a new cultural vane, more and more people are willing to come to Qin State to have a look and learn. On the world stage, Qin State is no longer a country that only has military skills.

However, Lu An was not successfully diverted from the subject by his younger brother. He turned his head and looked at him with a gentle smile. The Queen of Qin, who wore men's clothes without even a trace of makeup, couldn't help asking, "Why are you two coming to the academy today?" gone?"

"I came to pick up my elder brother together. Meng Tian is back." Ying Zheng said very naturally, rationalizing his behavior: "He also brought a new friend with him, and wanted to introduce us."

Lu An glanced at him, quite speechless.

Meng Tian previously served as a county lieutenant in East County of Qin State, and worked as a colleague of Lu An for a period of time. After Lu An returned to the Central Committee, he did not leave and stayed to take care of the enclave of East County. Play assist.

The governance model of East County is different from that of other major counties in Qin State. It can be said that it is also an experimental product, and Lu An was able to make drastic moves at that time without fear of backlash, and he also relied on Meng Tian as a reliable backing, and Ying Zheng. On the first level of relationship, the two get along quite well, so Lu An also knows some of Meng Tian's personal hobbies.

Meng Tian especially likes to modify all kinds of things, ranging from small brushes and inkstones to large city defense equipment. An important factor for Lu An and him to get along well must be because both of them are brains.

When Meng Tian came back this time, he naturally had a new job arrangement, and he was about to serve as the general who attacked Wei.

The land of Dongjun was originally the hometown of Wei State. Meng Tian had been stationed there for many years, and he also took advantage of the geographical advantage to understand the situation of Wei State. Show your skills.

As for friends... those who can be brought by Meng Tian as friends should be people who are really close to each other, and to be introduced to them is the person Meng Tian wants to endorse and recommend.Although Meng Tian is a military officer, he is used to acting mature and prudent, and has never recommended anyone. Lu An is really curious about this matter.

But Lu An raised one eyebrow, and signaled with his eyes that he would not accept this reason. Zhao Xiaozheng must have known the news that Meng Tian was coming, and the time was just right. How could it be such a coincidence that he came to the academy to give a lecture today, and Meng Tian will be here today Do you want to entertain guests when you come back?

Qin Guoxue Palace is located outside Xianyang City. Although there are defenses, the safety factor is far inferior to Xianyang City. Moreover, the personnel composition here is complicated. King Qin has no cubs and brothers. Don’t you know how valuable your head is, His Highness King Qin?

Ying Zheng said: He didn't do it on purpose!Who made things so coincidental, at most he contributed to the flames, but he was not in charge at all.

"Meng Tian said that his new friend was acquainted when he was playing the zither. The man's name was Gao Jianli, who was good at playing and building. He also helped Meng Tian change the zither and added three strings." Ying Zheng changed the topic: "The modified The zither has a wider range and is extremely pleasant to listen to.”

... ok.That's the point.

His Royal Highness Qin Wang has been a music enthusiast since he was a child. When he heard that his friend changed his instrument and brought back a person who is good at building, he couldn't sit still.Seeing that it was about the same time, Lu An packed up his things, left his big plan in the academy, and was about to leave with Ying Zheng and his wife to meet old friends, but when he was about to step out of the academy, he was suddenly stopped.

Lu An glanced at Ying Zheng, seeing his calm expression, he stopped and looked back to watch the excitement, and suddenly felt depressed. Although he planned in his heart that he must talk to his brother about safety knowledge after returning, he still got used to it. He took a step forward and stood in front of the unconscious King Qin.

Of course, in the eyes of outsiders, it was the meaning of Lu Neishi's permission to ask questions.

The person who stopped him was a young student. He was wearing plain blue clothes, not the school uniform of the Qin State Academy. Obviously, he was an overseas student from another country.

The young man approached and bowed to Lu An. After Lu An returned the salute, he got up and said, "Student Peifeng and student Xiao He, I have a question about Xiangsong, please feel free to answer it."

Lu An nodded his head as a signal, and heard the student say: "Students have low knowledge, but they also know that the method of abacus calculation taught by Mr. today has become a system. , and now Mr. took it out to teach, presumably to prepare for the future."

The young student raised his face and stared straight at Lu An, "Student, dare to ask, may I ask that the new tax law implemented by the State of Qin in the past few years is the reason for introducing the abacus calculation, isn't it?"

Lu An smiled, and the young man with a handsome face nodded slightly, "Although he missed, it's not far away."

"Sure enough..." Xiao He raised his eyebrows and said earnestly, "Qin's own tax regulations are clear, not complicated and treat all people equally, and the calculation is simpler. The student also lived in Dongjun for a period of time by chance, and Lu Neishi was from Dongjun. Although the seal period is short, it generally adheres to the principle of not disturbing the people, mainly encouraging and seldom coercing, so the students don't understand why Lu Neishi led the transfer of Qin's tax law.

"Students think that if the law is one, it will be easier to communicate. Now that the algorithm is complicated and adds cumbersome data, it is also a burden for local officials, and it is very easy to create loopholes. It is impossible for Mr. Lu to not discover the problems that students can see. But this method is also implemented, and the students really don't understand it. I would like to ask Mr. Lu to enlighten me on this question."

He bowed his hands and looked sincerely, obviously not here to find fault, but really curious about this question.

Lu An stretched out his hand to help him up, and said, "In your opinion, after the adjustment of the tax law, not only in the long run, but in the short term, will it benefit the people?"

"Naturally." Xiao He nodded, and his clear eyebrows stretched out: "Students dare to say that within three to five years, the wealth in the hands of people in regions that adapt to the tax law will double or even increase."

many. "

"That's the reason." Lu An smiled, and he looked over the face of the calm King of Qin behind him: "To ensure the implementation of the tax law, it is Qin who needs to work in calculation, supervision, execution, and training. There are a small number of officials in the country, but most people in the Qin country can benefit from the tax law, which is why we are working hard."

"As for your concern about adding burden and difficulty to local officials."

Lu Anlue pondered for a moment, then answered: "Our Highness King Qin once said a word when he was the prince: The stricter the law and discipline, the harder it is to be an official, the harder it is to be an official, the brighter the country's future, the better the people. And more hopeful."

He glanced at the shocked young man, and said, "Officials of the Qin State select the best, and we will select the best, so we are different from other countries."What they can't do, we can. "

He raised his head slightly, the pride from the heart burned the eyes of Xiao He and the onlookers.
