In fact, the matter between men and women is quite interesting, he doesn't want this product to be his brother-in-law because he likes Pei Xingjian, which is similar to the reason why Li Xiaogong didn't like him at the beginning, and once the matter between him and Li Xin was settled, Li Xiaogong suddenly became his biggest backer in the court, and the same is true for Pei Xingjian, his advice to Pei Xingjian is indeed heartfelt.

But these words to Pei Xingjian are not for themselves.

If you are promoted to a level in three years, you will wear a purple robe at thirty, what will you do after thirty, and you will be in the sky at forty and wait for retirement? He now has to say to himself twice a day words and truths such as taoguang and obscurity, gentleman's hiding utensils, and thick accumulation.

But I don't know what's wrong, why can't he hide this weapon like this, isn't it good when he didn't cross by himself, why can't he leave himself now, no, Li Yuan has another moth over there, just like that, he still doesn't understand.

Paying with pure paper money, paying wages has become a simple calculation problem, because it can no longer be as grinding and chirping as before, and the slightest mistake is obviously manifested, so that those officials who came out of the original Ministry of Civil Affairs are in a mess even if they work overtime.

all know that Qin Hao's arithmetic is unparalleled in the world, so Li Yuan actually came up with a bad idea to let Qin Hao train everyone, how busy he is, how can he have time to teach such things as basic mathematics, but Li Yuan's face He didn't dare not give it, so, after a long absence, Qin Hao took up carpenter work again.

"What's this?" Li Yuan and the others asked.

"This is called abacus, also called abacus, high-end mathematical problems can not be solved, but simple addition and subtraction is no problem, counting with this thing, learning is still very fast, as long as everyone in the bureau practices it, practice makes perfect, it will not take a few days to be proficient in this simple addition and subtraction."

This thing was invented in the Song Dynasty, although the Tang people also have a pay, but the operation is complicated and difficult to learn, ordinary officials do not want to use it proficiently after three or five years of hard work, and the error rate is still high, Qin Hao is also to save himself trouble, simply got this thing out.

Of course, Qin Hao's abacus is still made of ivory, connected with pearls, crackling, and breaking one will make him feel distressed for a long time, this is not his own use, but given to Li Yuan to block his mouth, in the name of being the leader of the Tang Federal Reserve, he will not intend to be unable to convince the public.

"Is this really going to solve our problem? Can an uneducated person learn it quickly? ”

So Qin Hao casually pulled Xue Li and said: "This goods, my brother, I didn't know how to do arithmetic three days ago, I taught him to do two days of arithmetic, and he can come to work with you." ”

"Really fake, three days."

"How can I lie to you?"

So Li Yuan asked with great interest: "There is an official today, who has a monthly income of 723 yuan, five silk horses, 610 wen each, and a fine of 540 wen for work mistakes, how many vouchers should be issued to him?" ”

As Li Yuan spoke, Xue Li's abacus had already been made, only to hear the crisp sound of crackling and crackling, and when Li Yuan finished speaking, Xue Li also listened to it, and said, "It's three runs and seven hundred and ninety-eight texts." ”

Li Yuan was shocked when he heard this, so fast?

At the same time, Xiao Yu was also taken aback, this number was obviously Li Yuan's casual nonsense, even he had to calculate it for a long time, this Xue Li kid was faster than his money bag in the Tang Empire for more than ten years, it can be said that there will definitely be no more than ten people in the entire Tang Dynasty with this speed, is this all that kind of calculation? Did he really only study arithmetic for three days?

Qin Hao smiled and said: "Emperor Taishang, the only arithmetic that this abacus can calculate is basic mathematics, that is, a simple account or something, it is naturally no problem to give us an emergency, but if the Tang Fed wants to develop, it must use many high-level mathematical means, I wonder if you can open a training class, choose a clever little official to teach it, and a few of you who are interested in it will also listen to it, in the future, when it comes to printing money, leaving this thing to print blindly, it will be a disaster to the people, and the meaning of our Tang Fed will not exist." ”

"Oh?"

Li Yuan was surprised: "You lazy man agreed to teach arithmetic in person?" ”

Qin Hao smiled and said: "My set of things, to be honest, is too high, I have already written a letter, from His Royal Highness the King of Yangzhou Guan Yue to ask for someone, he has a lot of people who are good at arithmetic, I want them to join our Tang Federal Reserve, when the time comes, it will be enough for them to teach the officials advanced arithmetic, if there are talented and intelligent people among them, choose one or two and hand them over to me to learn some advanced things." ”

"Blue Sparrow? It doesn't matter who he wants. ”

"It's some people from Fanbang who are from Dashi, Dashi arithmetic has many merits, and their navigation skills are indeed above us, so let them stay in Yangzhou to guide me Qinggang shipbuilding, which can be regarded as a consultant, and at the same time teach His Royal Highness King Yue the art of arithmetic by the way."

Li Yuan nodded and said, "It turned out to be a foreign country, and I didn't expect that there would be a time when a foreign country would teach us." ”

Qin Hao explained with a smile: "That big food is located in the desert and the poorest place, but it is connected to the sea everywhere, so the sea trade is naturally more developed than ours, if you talk about other things, it will be dwarfed by us." ”

China in the Tang Dynasty can be called tolerant of all things, daring to accept the Siyi culture with an open mind and identify with foreign customs, so although Li Yuan was surprised to learn from foreign countries, he did not show unacceptable emotions, which made Qin Hao greatly relieved.

This is the peculiarity of national culture, when a civilization is really strong, accepting foreign things is very tolerant, and all things that are not in the country will instinctively feel interested and tolerate themselves, but it is poor and weak, and the mother who was beaten by a foreign race can't recognize the dog's blood, but it is always arrogant and arrogant, the god is the eldest and my second, and the mouth is open and closed, it is the Fanbang barbarian, which seems to be the case thousands of years ago and thousands of years later.

"Qingque went to Yangzhou for half a year."

"Almost, I went during the autumn harvest, and now it's almost spring."

"Alas, let the local affairs do it yourself, what is the use of him staying there with a doll's family, in my opinion, just call him back, this is also the meaning of the second child."

As he spoke, Li Yuan also glanced at Qin Hao with slanted eyes, as if observing his reaction.

Qin Hao sighed in his heart, but his face was silent, after all, he had long known that there would be such a day, and it was impossible to tie Li Tai to Yangzhou at all.

Fortunately, Li Chengqian has been in charge of the country for more than half a year, and he wants to do a good job, solving the problem of salt introduction in the crisis society, even if Li Tai takes the great contribution of developing Yangzhou, it is far from being comparable.
