Chapter 295: teach

Oh? Except me? Lin Wanrong couldn't help but took a sigh of relief. What does this old Xu mean? You have my idea, I'm fine, but the point is that your girl is wrong with me now.
When the young lady saw Xu Wei and Lin Sans talking, and saw that Xu's face was miserable, she took her hand and said, "Sister Xu, Miss Su, Lin San's person is a bad mouth. Let's not listen to his nonsense. Go, We go in and I have something for you. "
Lin Wanrong knew that the young lady was about to send out perfume. Haha laughed twice. The young lady flushed, glared at him, took the account book, and took the two women into the inner courtyard.
"Brother Lin, brother Lin, do you hear me talking to you?" Xu Wei's voice sounded in his ear.
"Ah, haha, I heard it, I heard it, what or what—" He slapped haha: "Mr. Xu, let's talk about these things later. Look at this portrait first. Do you know this woman?"
He took an image from his arms and handed it to Xu Wei. Lao Xu took the portrait. I saw that the brush method was unique, the corners were concise, and he painted a woman who fluttered like a fairy. His expression and looks were stunning. He looked at it for a moment and frowned. "It seems to be a bit of an impression, but I can't say where I've seen it."
Lin Wanrong was overjoyed, grabbed his arm and said, "Mr. Xu think again, have you seen it in the palace?"
Xu Wei shook his head and said, "Just looking at it seems to have an impression. As for whether I have seen it, I am not sure."
Lin Wanrong said: "Have Mr. Xu ever seen the second princess of the emperor?"
Xu Wei smiled bitterly: "The second princess? I have seen it when she was young. In the past ten years, she has been living in a low profile. She has been low-key. People who have met her may be the emperor. The long princess also did not meet with the second princess. Alas, this involved a secret when the emperor ascended the throne. Not to mention. "
Lin Wanrong said: "Look at Mr. Xu, does this lady look like the long princess or the emperor?"
Xu Wei glanced and laughed: "Brother Lin, you asked me so much, is it the second princess in your painting?"
Lin Wanrong nodded and said, "I'm not quite sure, it's just a little skeptical. If this is really the second princess, there should be some similarity between her and the emperor or long princess."
Xu Wei shook his head: "Although the appearance of a person is taken from his parents, it is also very different from his parents. It is too biased to judge the blood relationship based on the appearance alone. The royal blood is even more so, princesses of all dynasties. Never Ugly man, why is this? Because the emperor has his own majestic temperament, his appearance will never be too bad, and the concubine is even more beautiful, so the princess born has the advantages of his parents. Mostly beautiful Abnormal, because the majesty of the emperor is not suitable for women, so most of these princesses inherit the appearance of mothers, so let ’s say that long princess, she inherited the appearance of her mother, as do the second princess. The princesses are half-sisters, and it is normal to look alike. "
Lin Wanrong was a little disappointed. If Qingxuan looked like the long princess or the emperor, it would be better to judge, but Lao Xu threw out a statement that "the royal princess looks with her mother." It seems that it is really difficult to know Qing Xuan's identity just by appearance. Is it really necessary to do some credit, wait for the emperor to open a golden mouth, and ask Lao Tzu to enter the inner palace?
Seeing that there was no breakthrough from Lao Xu, Lin Wanrong was quite helpless, Qing Xuan, Qing Xuan, are you a princess?
The two talked a little more. Lin Wanrong said to him what the military situation was about. He said that the frontier was a long way away, and that our army was really powerful, and that there were no borders. Xu Wei was very depressed, and this boy After speaking for a long time, he didn't know whether he wanted to go or not. The first bachelor met the first sliding head, it is also okay.
When Lin Wanrong and Lao Xu entered the inner courtyard, I saw Su Qingli and Xu Yiqing holding a bottle of perfume, and was curiously playing with it. Miss Xu's face seemed to look a lot better, and she applied some perfume on her crystal-like jade wrists. Smelling it gently, a smile on his face appeared: "It really is fragrant but not strong, charming but not vulgar, good sister, this is really a good thing, I like it very much, and I still want it. A bottle of orchids. "
Khan, holding a bottle of roses in his hand, and another bottle of orchids, which tone does this girl like? Is it sometimes pure and sometimes coquettish? The strange woman really has a different taste, which is very similar to my taste.
Su Qing said with a smile: "Yi Qing, this perfume can't be grabbed in Hangzhou, the price has been doubled, such a small bottle has been fried to 320 silver. The ladies in Beijing have also started It's spread, but the number is too small, and very few people know that everyone cherishes it. If you open your mouth, it will cost hundreds of dollars. "
Xu Yanqing smiled and said, "Auntie, I know it naturally. The first time I met with Sister Yu Ruo, she was so generous. If I don't want to get a bottle anymore, wouldn't it be a loss? Besides, Sister Yu Ruo is also a smart person She asked us to promote her. "
When the young lady saw that Xu Qingqing and other noble women loved the perfume, she naturally rejoiced and laughed: "Anyway, I'll give sister Xu and Miss Su a bottle of orchids. This is the brewing method of our family. Nowhere else. "
Miss Xu glanced at Lin Sanyi with a faint whisper. Lin Wanrong touched her nose and said to her heart, I thought you heard that I made the perfume, and I will return these two bottles to the young lady. According to the black market price, this is 620 silver.
While thinking about it, Xu Xuqing took the young lady's account book and slowly came over and said, "Lin—Lin Gongzi, I have something to ask you."
When Xu Wei saw her daughter talking to Lin San, she suddenly laughed and said, "You two have extraordinary insights, and you should talk more. Miss, the old man is lying in your house today, asking for a glass of water and wine, Qing pity, go I took the piano, and I'm in a good mood today. Let's sing a little song and have fun with the younger brother, Lin— "
I , I have a word with your daughter, you are singing and dancing again, and you are good at food and wine. It is me who contributes, and it is you who enjoy it. Is there any logic? Lin Wanrong shouted, "Ah, Miss Xu, may I ask? Later, I want to listen to Miss Su playing the piano, too. Speaking of it, I like to talk too much, but it's not good. No talk about a few. "
Xu Yiqing nodded faintly: "I was going to ask Mr. Lin about Arabic numerals, but since you are not empty, let's forget it."
Lin Wanrong was shocked: "Do you know Arabic numbers?"
There was a hint of sly light in Xu Yanqing's eyes, and he smiled, "Let's listen to Aunt Su first, doesn't Lin Gongzi like it?"
, This girl is pure revenge. Lao Tzu was in a relationship with you today. He laughed and said, "If that's the case, then forget it-well, I originally wanted to discuss with Miss Xu the calculation method of the Arabic numerals- —Well, let's talk, let's talk! "
The two of them had a mischievous heart, and secretly competed, but the patient was to see who surrendered first.
After taking a few steps, Lin Wanrong remembered that he wanted to spread Arabic numerals in this world. Although this is a foundation, but when it is done, it is definitely a matter of benefit to the country and the people. Maybe Dahua's pace to catch up with Europe has since How about it?
Lao Tzu does not make cannons, and is unwilling to make gunpowder, but if the basis of mathematics and physics is spread, it is something that will benefit thousands of generations, let alone, I will do this unknown hero. Xu Qingqing has perseverance and perseverance, and knows the Arabic numerals. Why should I delay this opportunity for the sake of fighting?
Thinking of this, he suddenly stopped and said solemnly: "Miss Xu, I won't hold my breath anymore, let's talk well, no matter how you look at me, when I'm nonsense, when I'm not learning nothing, I want to say This Arabic numeral and the calculation method based on this time is an extremely great invention. Without it, there would not be the power of Westerners. Mastering it, Dahua may be a brand new era. "
Seeing his solemn expression, Xu Yanqing seemed to have changed his face with the angry youth who had just turned out, and could not help but sigh: "This is what you say when you change. The Arabic numbers were passed in by Westerners. For the record, I also saw a slight record in the miscellaneous book translated by Missionary York. Today I saw that you counted in Arabic numbers on the account book of the young lady, and I was curious, so I asked the last one. This Arabic number is really Did you speak so hard? "
"It's not terrible, I said no, so let's do an arithmetic problem. Let's calculate it together and prove it by facts." Lin Wanrong said.
This is indeed fair. Xu Zhengqing nodded and thought for a moment: "Then I will ask a question. A chessboard with five horizontal and two vertical columns has ten squares, the first square is one or two silvers, the second square is two or two, and the third There are four or two grids, and so on. How many silver coins are needed to fill all ten grids? "
See Miss Xu calculate with a pen and paper. Lin Wanrong calculated it with a smile and said, "No need to count, one thousand two hundred and twenty-two."
This question was made by himself, and he must not be able to cheat. Miss Xu was surprised: "How did you calculate it? Is this the calculation of Arabic numerals?"
Lin Wanrong laughed: "I can't tell you now, when you learn to use Arabic numerals, you can deduct these formulas yourself, Ms. Xu, if you have a broad knowledge, can you tell me, do you find it convenient to use the calculation method? ? "
Xu Yiqing thought for a while and thought, "I didn't find it complicated before, but I just met you, and it seems I have to reconsider this question."
Lin Wanrong nodded and said, "I tell you, whether it is astronomical calendar or engineering calculation, this Arabic number is the most useful calculation method. If you want to learn, I will teach you this set. I also do not expect Can you remember me well, I just hope you learn these well, and then teach it, let more people who are interested in mathematics and engineering join in. Everyone brainstorms, carries forward this mathematics, and if possible, organizes them into The book has been circulating. With this, I am satisfied-what do you think I am doing, do you think I am great? I tell you, do n’t engage in personal worship, I am afraid there will be problems. "
Xu Yanqing shook her head and smiled: "You, I just think you are serious, but you have changed again. I remember all of what you said. In fact, this is what I have been doing." ]
Lin Wanrong was so eager to pass down this calculation method. In the face of Xu Yiqing, he was very meticulous. Unfortunately, he had not been a teacher and talked about elementary school mathematics. He also felt a little bit confused. Playing tricks is his strong point, so careless.
Xu Xuqing was so clever that she knew these Arabic numbers. Lin Wanrong told the four operations only once, and she understood, let Lin Wanrong secretly whisper-this girl is much smarter than when I was in elementary school.
Seeing her so easy to learn, Lin Wanrong simply taught her what index calculations she did, whether she understood it or not. In this case, Lao Tzu can only teach ducks. To understand, you Go slowly after class.
After talking for a long time, Lin Wanrong was all dry. That Xu Yanqing sighed: "The Arabic numbers are really exquisite. With these counting methods, my Dahua craftsmanship can definitely go further."
Lin Wanrong nodded and said, "Miss Xu, how much do you write down?"
Xu Minqing lowered her head, her face flushed slightly, and whispered: "I only remembered Jiucheng, and the last index did not pass through ~ EbookFREE.me ~ Khan, it really is a genius. Let me talk about it. To prove her the Pythagorean theorem, it's enough. Lao Tzu's task is completed, and the rest will be understood by her.
He and Xu Zhengqing also met a few times. It was the first time to see her blushing, and she couldn't help but sigh with a sigh of relief: "Well, let's do it. Among the students I have taught, you are the slowest to understand Yes. "
Xu Yanqing is not that easy to be bluffed. She looked up and said, "You are not blushing when you lie. However, I am curious. You are not smart. You do n’t know the knowledge of the Arabic numerals. Where did you learn from?"
, I'm not smart enough. Which eye do you see? Lin Wanrong said indignantly: "I'll tell you the day when you think I'm smart enough. I'm hungry and go to eat."
Xu Yanqing froze for a moment, then giggled, the plump Jiao's body trembled sharply, and she couldn't even straighten her waist ...
