"Uncle, please sit down!"
Although he didn't know who Fang Xuanling was, seeing that he had an extraordinary temperament and that he was a guest, he naturally invited him in first.
"You are Tang Ping, the proprietor of Shanghe Village, right?"
At this moment, Fang Xuanling also thought about it. At that time, it seemed that Shanghe Village was awarded to Li Jing by the emperor. Then Li Jing said that someone was kind to his family and asked the emperor to transfer the village. He also skipped the formalities. Again.
However, the Turks happened to be defeated at that time, and everything was complicated. This kind of thing was not important to them, so it passed.
But in the short time he had been here, he no longer dared to underestimate the young man in front of him.
Speaking of which, this young man should be about the same age as his own kid, but why is he someone else's child?
"The next one is Tang Ping! What do you call uncle?"
"Just call me Uncle Qiao!" Fang Xuanling took the tea from Lu Yi and glanced at Lu Yi in surprise. Why did he seem to have seen this girl somewhere?
Later, I thought it might be from Li Jing's house. After all, Li Jing gave this to Tang Ping. It would be normal to give him one or two maids.
I just don't know why Tang Ping is so kind to Li Jing's family and allows him to give away land and people.
"Where is Uncle Qiao from? Is he from Chang'an?"
"Yes, I live in Chang'an. The weather is nice today, so I went out to the city for a walk." Fang Xuanling took a sip of tea and felt a little moved in her heart. This tea is sweet and refreshing, which is completely different from the tea everyone usually drinks.
"This tea..." Only then did he see the tea in his cup was light amber, clear and clear.
"Hahaha, it's mainly because I'm not very used to the tea you adults drink. I just made this one simply."
In the Tang Dynasty, tea was still brewed. The tea in it was ground into powder, and a lot of seasonings were added. It was very different from our modern tea that is brewed directly.
At that time, Tang Ping bought some out of curiosity and asked Luyi to make it according to Datang's method. After that, he never mentioned drinking Datang's tea again.
"Yes, it has a different flavor!" Fang Xuanling thought about it for a while. Although the taste was not as good as the tea he usually drinks, it did have a different flavor as he said.
As expected, Shanghe Village has a unique feeling everywhere.
"Just now outside, I heard that the villagers in Shanghe Village were wearing that..."
"Work clothes!"
"Yes, work clothes, that was also invented by Young Master?"
"No, I just bought it."
"Bought it?" Fang Xuanling asked doubtfully, "I wonder which tailor shop made it?"
Although the style of the clothes looks weird, if you think about it carefully, you can see that it is extremely efficient for working. If there is such a tailor shop near Chang'an, there is no reason why he doesn't know about it.
"Well, I didn't buy it near Chang'an..."
"Oh!" Fang Xuanling nodded. At this time, the folk trade among the people in the surrounding countries of the Tang Dynasty was still very developed. He thought that Tang Ping was buying it from a foreign caravan, so why did the style feel so strange? It worked.
"Then your line goes all the way to the river?"
"This is an electric light so that the villagers can see the road after dark at night." Tang Ping felt that there was nothing to hide from this thing.
"Light the lamp?" Fang Xuanling nodded again: "Dragon Master Tang is very thoughtful. He can light lamps for the villagers at night, which shows his kindness!"
Although Tang Ping was a little surprised why Fang Xuanling was so calm about the electric light, he didn't ask any more questions.
It can only be said that the cross-channel chat between the two was very successful. Anyway, no one deducted money for the homophonic joke.
"Just now outside the courtyard, I accidentally overheard Dongzhu Tang and his disciple Gao Gao questioning each other. Disciple Gui Gao is quite proficient in arithmetic!"
This is the question he wants to ask most now.
You must know that the province handles national affairs, and there is a lot of arithmetic involved.
Otherwise, how can we say that mathematics is the basis of everything?
Li Bai's calculation speed just now was unmatched by many officials in the province.
"Isn't that a question in Sun Tzu's Sutra?"
"Sun Tzu calculates scriptures?" Fang Xuanling asked doubtfully: "I know Sun Tzu, a military strategist and sage, and there are thirteen chapters of Sun Tzu's Art of War, but I have never heard of Sun Tzu calculating scriptures?"
Fang Xuanling was a Jinshi at the age of eighteen, and he was considered well-read, but this was the first time he had heard of his grandson's calculation of scriptures.
"Uh..." Tang Ping didn't know how to answer this question. This question was nothing to modern students. He also saw on Baidu that day that it was a question from Sun Tzu's Arithmetic Classic, and Sun Tzu's Arithmetic Classic should have been written in More than one or two hundred years ago.
But now it seems that there is no such book in the world. Last time he asked Li Bai, Li Bai said that he had never read it. He thought it was because he did not read enough books at his age.
"I wonder if this grandson's sutra calculation can be lent to me?" After Fang Xuanling finished speaking, he felt that he was a little abrupt, and quickly added: "I can exchange it for other books or things."
If it were something else, he wouldn't be so excited, but this book is called Sutra, and it must be about arithmetic, and the arithmetic level that Li Bai showed just now made him feel that if it could be popularized, if nothing else, at least It is of great benefit to the efficiency of office work.
If Tang Ping had this book, he would definitely have given it to him, but the key point is that he didn't.
And based on his mathematical level, the contents of the arithmetic book are a bit too childish. Now, even the kid from Shanghe Village can solve all the above problems after studying with him for almost a year and a half.
Looking at Tang Ping's look, Fang Xuanling thought he was unwilling, but it wasn't surprising when she thought about it. Nowadays, many things are passed down from male to female, let alone to an outsider?
At this moment, the system in Tang Ping's mind suddenly spoke.
"Small side tasks allow the seeds of mathematics to take root, sprout and bear fruit in the Tang Dynasty!"
"Failure penalty: None!"
"Reward for completing the mission: a blind box."
"A blind box?" Tang Ping was speechless: "What exactly is in it?"
"It's said that it's a blind box, of course you won't know until you open it!"
Well, this is very systematic. There is no penalty for failure in such a task. As for the reward for completing the task, I don’t know what it is, but I think it is better than nothing.
And such a task is indeed easy for Tang Ping to complete.
Asking Fang Xuanling to wait a moment, he went back upstairs and dug out the abacus he used when he was in school, along with the abacus formula he used at that time.
At this time, the most commonly used method was abacus, which was still much less efficient than the later abacus.
Tang Ping felt that he couldn't teach things that were too troublesome, and with his salty personality, it was hard to find trouble.
As long as the abacus and Arabic numerals can be popularized, he feels that it will greatly promote the development of arithmetic in the Tang Dynasty.
So Tang Ping spent the entire afternoon giving Fang Xuanling math lessons, because the uncle said that he worked in a government department and had to use arithmetic a lot in his work.
It just so happened that Tang Ping could start promoting mathematical knowledge from him.
