Xue Lang was a happy guest in the Su family, but Pang Qingyun, the general of jinwuwei in Nanya County, frowned because of the three young men who had been taken back. Su Rong said in a deep voice, ”Chen Wei, tell me the situation again.”
”Here it is
Chen Wei, kneeling on one knee, said, ”my humble duty is patrolling the city today. Some people report that someone is trying to shoot the Duke of Changping on the street with his keepsake. The humble official hastened to take people over to check. The two sides of the conflict were Lu Jing and the Duke of Changping County. Lu Jing and his followers have been knocked down by the guards of Changping County. Lu Jing's three men were surrounded by four spirit dogs. Lu Jing held a bow and arrow in his hand, and there were arrows on the ground and on the wall. According to Jiang Xiaowei, who accompanied him to protect Xue Jun Gong, Lu Jing wanted to kill the spirit dog, which led to the conflict between the two sides. ”
Pang Qingyun's expression was more serious and confirmed: ”so, Lu Jing did open a bow?”
Chen Wei said, ”yes. Lu Jing argued that he did not know Xue Jun Gong's spirit dog. He thought that it was the wolf who came out to look for food and hurt people, so he opened his bow and shot him. ”
Pang Qingyun snorted coldly and said, ”nonsense! Chang'an City, also dare to open a bow! Who gave him the power? Is Lu Jing the guard of Nanya or the forbidden army of Beiya? ”
Chen Weitou lowered his voice and said in a low voice: ”Lu Jing is the third grandson of Fan Yang's Lu family's four families. It is said that Lu Jing is very popular with his grandmother, so he is quite arrogant.”
Pang Qingyun sneered: ”arrogant? Why is it better or worse? How dare you open your bow to Changping County? What's more, the saints paid more attention to the Duke of Changping County. Let's not say that the Lu family of Fan Yang, even if he is a descendant of his clan, dare to bow openly to Changping County, the sage will not forgive him! ”
Chen Wei replied: ”I have heard that Changping County has a righteous younger brother named Jiang Lin, who married the fourth daughter of Su Lun, a doctor of mathematics in the Imperial College of the Imperial College. Lu Jing had taken a fancy to this girl before, and wanted to be employed as Teng concubine, but Su Lun refused. When he sent for a marriage proposal, he was beaten by Jiang Lin
Pang Qingyun asked, ”can Jiang Lin be present today?”
Chen Wei said: ”general Hui, it is said that Jiang Lin is highly skilled in martial arts and serves as a school captain in Princess Pingyang's army. This time, the Duke of Changping went to Beijing to offer good fortune and was ordered to lead a team to protect the Duke of Changping. Today, the Duke of Changping county is visiting Su's house, and Jiang Lin is naturally present. ”
Pang Qingyun had a sarcastic smile on her face: ”it's so! Lu is really good at teaching children! However, this is Chang'an, not Fan Yang. When did Lu's prestige spread to Chang'an and to our jinwuwei? ”
Chen Wei shrunk and immediately pleaded guilty: ”the humble duty is guilty, please punish the general!”
”That's it! You were born in Fanyang and have heard of Lu's reputation for a long time. You will be afraid of Lu. However, this matter is not a matter of Jin Wu Wei's authority, but should be transferred to Chang'an government. I promise you to do a little bit of friendship with your fellow countrymen and tell the people who are in charge of the capital city of Lu. ”
Chen Wei immediately gratefully saluted: ”humble duty, thank you for your sympathy.”
Pang Qingyun said: ”you can send someone to wait outside the gate of Huaiyuan square. When the Duke of Changping comes out, you can tell him. Because of the limited authority, Lu Jing and other people have already transferred Jin Wuwei to Chang'an house. As a bitter Lord, Xue Jun Gong can redress the injustice to the governor of Chang'an.”
”Here it is
Chen Wei took orders and left.
Jin Wuwei and Chang'an government offices are full of people. What about Xue Lang? He was also a guest in the Su family, discussing Arabic numerals and mathematical symbols with his father and son.
A group of men gathered around a table. Xue Lang took out his pen, and Dr. Su took out his bamboo chips. Xue Lang wrote Arabic numbers against the numbers on the bamboo chips.
Mathematical research in ancient China is very advanced. In the book of nine chapters of arithmetic, there are not only calculation methods of plane geometric area, calculation of fraction, square root, open cube, volume calculation method of solid geometry, tax apportionment, first-order equation, etc., which is a relatively advanced mathematical work in the world.
The only drawback is computing tools. Before the Ming Dynasty, when people calculated, they used bamboo chips. Bamboo chips were engraved with numbers. Therefore, they were also called planning. After the Ming Dynasty, abacus appeared, and abacus gradually replaced calculation.
Xue Lang can't do abacus calculation. In the past, when he calculated, he used either a calculator or a pen and paper method. He is proud of his way of calculation, but his method of calculation is not so fast.
Dr. Su commented from the perspective of a doctor of Mathematics: ”Youyang's method is indeed simpler. Even if it is written on the ground without paper, it can be calculated, which is more convenient than bamboo chips.”
If you use bamboo chips to calculate, if it is simple, it's OK. If it's more complicated, you have to take a big bag of bamboo chips alone. Comparing with Xue Lang's several figures, it's really complicated.
Several men discussed for a long time, and Su Mu came to urge dinner for three times before planning a group of men to talk about it. Naturally, the food preparation was not as luxurious as that of the princess mansion and the imperial palace. It was only slightly better than the ordinary food, but Xue Lang was very satisfied with it. As a guest, what you do is your mind. Nothing else matters.
It's steamed buns. They're given preferential treatment. Su Mu seems to really like them. She is very generous. She gives a leg of lamb and eats four dogs full of oil. She also wants to add chicken legs to them, which is stopped by Xue Lang -
