Landlord of the Tang Dynasty

Chapter 388 New Calculus

"Sister, the emperor is not the kind of person who likes women who don't understand anything. If you do something practical, even if you have your own thoughts, as long as you don't hide it from the emperor, he will not care about you." Huang Shimei continued to persuade Concubine Wan Gui: "As long as The ministers outside have agreed, and the emperor is naturally willing to go with the flow."

"Which ministers really think that my sister is virtuous, instead of thinking that my sister is not a concubine?"

"Fairness is in the hearts of the people. Besides, even if my sister has done something wrong, who can say that this heart that works hard for the country and the court is not right?" Huang Shimei said slowly: "Filial piety comes first, regardless of deeds. Heart, there is no filial son in the world; all evil and adultery are the first, regardless of the heart, there is no perfect person in the world."

Hearing this, Concubine Wan Gui's eyes became firmer, she nodded and said: "My palace pays, can you contribute your strength? This is recruiting people, looking for a factory, it's not easy for me to go."

Huang Shimei smiled and said: "How can you say that, the imperial concubine and our four sisters all contribute so much money. We can do things as well, as long as the imperial concubine comes to a tea party from time to time, and invites all our guests. it is good,"

"Hahahaha..." Concubine Wan Gui smiled heartily, and immediately agreed to send someone to send money tomorrow, and the five people will share it equally, and each will pay 500 taels first.At this time, Xu Qi broke in suddenly, holding a small wooden jar and said, "I want to participate too, I have money!"

Crash, Xu Qi opened the small wooden jar, and accidentally knocked it over to the ground, rolling the silver fruit all over the floor.

Xuanwumen

Three poles in the sun.

"Whoever wakes up from a big dream, I know it all my life, the cottage is full of sleep in spring, and the sun is getting late outside the window..." Xu Qing turned over like a carp, and kicked the quilt away.Because of the sound of sleeping, Xu Qing unconsciously recited poems.

At this time, a voice came from outside the door: "Master Xu is really eloquent!"

Naturally, Xu Qing knew that it was Wei Xian who came, brushed his teeth with peppermint salt water, Xu Qing put on his official uniform, and went to the front office with Wei Xian to sit down.On weekdays, Xu Qing has never been there, but not today, because several doctors of mathematics from Taixue are coming, so he has to sit in the office.By the way, Xu Qing ate some biscuits in the cafeteria in the school grounds.After thinking about it, Xu Qing kept half of it and put it on the official office's table, and poured out half a bowl of soup and put it on the table as well.

It didn't take long for the soldiers outside to report: "General, there is a scholar from the Zhaowen Museum outside the door, and a doctor from the Taixue School of Mathematical Confucianism is asking to see you."

Xu Qing thought that he finally came, so he got up and followed the soldiers to meet him outside.But seeing a few gentlemen in the early years, they walked in.After sweeping these people away, Xu Qing felt relieved.In ancient times, being an official was a glorious thing. When a young man became an official, he was young and ambitious, so he was bound to be proud, so he walked with his head held high.But when they are old and become officials, they know how to be respectful, and most of them are a little hunchbacked.

The few people in front of him are all hunchbacked people.Seeing Xu Qing go out to greet him, several people immediately knelt down and said, "Your Majesty, I will see Mr. Xu."

Xu Qing hurriedly helped them up and said, "Masters, please sit down in the official office."

Different from other officials, these doctors are all literati, and they are different from the literati of the Qing Dynasty.Since he is a literati, he must have the arrogance of a literati. To deal with this group of bachelors, Xu Qing needs to retreat.

Xu Qing's official office is not big, there are several seats in front of them, and they can see clearly what is on Xu Qing's table at a glance.Seeing Xu Qing's table half of hard biscuits and a bowl of clear soup, several doctors couldn't help but nodded and praised: "Master Xu is in a high position, but he can live such a simple life, he really has the style of two saints. "

Xu Qing laughed in his heart after hearing this, cleaned up the things on the table, and then said to several doctors: "Dr. It’s hard for one person to do it alone, and we need your help.”

Several doctors clasped their hands together and said: "Master Xu is the leader, we will follow him."

"Ahem, the first thing to do is to get to know these new numbers, please take a look..."

Xu Qing told these doctors what he told Li Yuan and the others last night.They are indeed people who are proficient in arithmetic. When Xu Qing explained the rules, they understood them by heart, much faster than Li Yuan and the others.From noon to night, Xu Qing had already used Arabic numerals to do elementary school arithmetic that he thought of.

After singing an affectionate song, all the people present became quiet, immersed in the beauty of the new numbers, unable to extricate themselves.At this time, Wei Xian brought up several bowls of tea, and everyone took a sip.The doctors stood up and said to Xu Qing: "Thank you, Mr. Xu, for your enlightenment..."

Xu Qing waved his hand and said, "I don't need to thank you for doing things for the court. It's just that my new numbers are here, and everything you can think of has been said, so you can use them to compile books."

Several doctors bowed: "Your officer obeys."

Xu Qing sighed and added: "The compiled books should be written in vernacular as much as possible, and some incidents that can be encountered in life should be selected as examples. It should not only explain the principles of calculation thoroughly, but also let readers know the application. "

Several doctors glanced at each other, and asked suspiciously: "Master Xu, do you want to use vernacular for this new calculation?"

Xu Qing nodded and said, "This new arithmetic not only needs to be seen by the scholar-bureaucrats, but also benefits the common people. This is also the purpose of my creation of new numbers."

Arabic numerals can be widely used for the convenience of calculation, and the purpose of convenient calculation is for the common people to understand and learn well.In this way, the common people will not be deceived by the word games of the aristocratic families.If the aristocratic family is allowed to monopolize knowledge again, it will violate Xu Qing's original intention.

Yingzhou
Prince Li Jiancheng has sent troops for half a month. Due to heavy snow and road closures, the enemy has not been seen for many days.For half a month, there was no meritorious service.It seems that Xue Yantuo got half of the letter, and just shrank in his hidden tent, refusing to send out the cavalry.

When the first ray of spring breeze blew to the northern fortress, Li Jiancheng was tired of not being able to find the enemy, especially at this time, his cronies had already told him the news of Li Shimin's victory in Tuyuhun.

The white jade wine cup and the emerald wine jug were overturned by Li Jiancheng to the ground, and then the generals gathered together with drums beating.Li Jiancheng said, why should he find Xue Yantuo when the snow is still deep and the cavalry is inconvenient, beat him hard, and then let the generals advise.

The generals hesitated for a moment, and they all advised Li Shimin not to send troops, and the main task was to keep the fortress safe.Li Jiancheng was furious, and whipped several generals who strongly opposed it. Half an hour later, a group of men and horses left Yingzhou City.Then, an urgent letter rushed from Yingzhou to Chang'an.

I saw this brave man, with excellent weapons, tall and big, and he looked like an elite.In fact, this is Li Jiancheng's own pro-army, the Longwu Army.Qin Wang Li Shimin also has his own pro-army, called the Shence Army.In addition, the Shenwu Army and the Yulin Army are old man Li Yuan's pro-armies. Among them, Xu Qing's Yuan Cong Forbidden Army, who followed Li Yuan since Taiyuan, also belonged to the Shenwu Army.
