Lu Hongniang walked in calmly and saw the young man Yushu orchid in the lobby, each with his own charm, and thought to herself that Duke Yun is very blessed. "Aunt?" Lu Qing stood up with a rubbing smile, his face full of surprise.
I was just muttering to her in my heart, and now the real person is appearing in front of me. Could it be that I am dreaming?
Lu Maoniang looked at Lu Qing up and down, then glanced at the others quietly, and curled her eyes with satisfaction.
It's the best little boy in your family.
Lu Qing quickly asked Lu Maoniang to sit in her seat and warmly served tea and water: "Aunt, why did you come to Hezhong Mansion?"
This aunt in her family is considered an alien in the family.
Although she inherited the beauty of the Lu family, she has not liked piano, chess, calligraphy and painting since she was a child, and she likes to calculate the scriptures the most.
My grandfather hired her a master, hoping that after she graduated, she could manage the family's business and manage the accounting room.
Unexpectedly, Lu Maoniang despised the Lu family's industry was too small and it was not challenging to manage the books, so she decided to go out for a study tour.
This trip took me more than ten years.
If she hadn't written letters to her home every year, her family might have thought she had died in a foreign land.
Lu Maoniang picked up the tea and took a sip: "Don't bother why I came here. Are you in trouble, little guy?"
Although Lu Maoniang went home a few times It is countable, but I often heard my brother mention this youngest son in letters. He admires Duke Yun the most.
When Lu Hongniang passed by Hezhong County, she guessed whether this little nephew would come to join her. Later, when she inquired, he was indeed here!
Lu Qing was embarrassed to scratch his head: "Auntie is so amazing. I am really in trouble. Yunguo Bus gives us a task, which is to supervise clerks to measure the land. Unexpectedly, these clerks bully us and don't understand the method of measuring!"
Lu Qing's eyes were red: "This is a test given to us by Duke Yun! If you can't even do this little thing well, how can you have the right to stay by Duke Yun?"
Lu Hongniang's smile faded and she sneered: "I actually bullied our Lu family! Look, my aunt stands up for you!"
Cui Letian and others have never seen her before Lu Mingniang, but Lu Qing seemed to have a backer and decided to believe Lu Mingniang once.
A group of people first followed Lu Maoniang back to the inn to pick up a few things, and then went to measure the Hong family's fields outside Hezhongfu with great fanfare.
Such a big fanfare action naturally attracted the attention of the clerks and the Hong family.
They sent some people to follow him.
When I arrived at the ground, Lu Hongniang glanced at it and found that the fields were not regular.
"This is definitely more than thirty-seven acres."
The Hong family servant said dissatisfied: "Don't talk nonsense, this is measured by Wu Xuli, the most experienced person. You What do you know about a girl? ”
Lu Maoniang took out the rope from her bag, let Lu Qing hold it and stand there: "My eyes are rulers!"
Lu Maoniang was in the middle of the field, facing everyone's doubts, and said confidently. : "You are just cheating with Qu Chongzhi, and you thought others could not calculate it. But when you met me today, you were considered a tough guy!"
Lu Maoniang pointed to the one in her hand Rope: "My name is a rope ruler. It is made of sixteen strands of ramie twisted and soaked in oil. Each zhang tied copper bell is used as a mark to prevent stretching and deformation. In addition to the traditional zhang size, a new scale has been added. .”
The copper bell jingled.
Looking at Lu Maoniang's confident expression, the onlookers and Hong family couldn't help but feel their faces.
Lu Hongniang doesn't care about how these people think. If she dares to bully her nephew, she has to be slapped in the face.
Lu Maoniang directed Lu Qing to various points while asking Hua Xu to record the data.
"Faced with this curve boundary, we can use the arc field method, which is to decompose the arc boundary into multiple string vector combinations, and calculate it approximately using the circle cutting technique."
Lu The matchmaker has no idea of hiding his own selfishness and shares it generously: "The calculation method is also very simple. Multiply the length of the string by the height of the vector and divide it by two. Use this number to add the third power of the vector and divide it by three times the string. Long."
...Lu Qing was confused, how could this be simple? I can't even understand it!
Lu Qing was a little suspicious, was he too stupid?
He secretly looked at Cui Letian and others, and found that the head of the scholar, the Cui family's treasure, had a look of wood, and was obviously confused.
Lu Qing looked at the clerks next to him again, and saw that their faces were very ugly.
After the data measurement was completed, Lu Maoniang blurted out: "Forty-six seven acres."
Wu Xuli's face was pitch black, just like charcoal.
They actually measured it privately, about forty-five acres. But this was what the five old guys did after four days of calculating.
How long did this girl take? Is there an hour?
Wu Xuli took a deep breath, smiling and said, "Miss Lu is really amazing. Now there is something that bothers us for many years. We have two villages in Hezhong Prefecture, and we have different opinions on the boundary line of the hillside. I wonder what advice Mrs. Lu has? "
Lu Qing was anxious: "What does this have to do with my aunt?"
Wu Xuli: "It has nothing to do with Miss Lu, but this is also one of our responsibilities for measuring land. Maybe Lu Langjun, what do you think?"
Lu Qing was speechless, and he didn't even measure the fields. Yes, let alone drawing the land.
No mistakes, one poem, one post, one content, one in 6, one book, one bar, one read!
Lu Maoniang curled the corners of her lips and signaled Lu Qing to put away the rope ruler: "Since that's the case, I will take it as my own and teach you well!"
The controversial realm is A hillside is not far from them.
The sun did not completely set the mountain, so Lu Maoniang decided to do today, and it was done today.
A group of people walked towards the hillside in a mighty manner.
The hillside is not high, and layers of terraced fields are developed.
It was early winter and the terraces were bare.
Everyone turned his eyes to Lu Maoniang.
I saw Lu Maoniang take out another thing: "This is the degree of moment. The slope and height can be measured, which is most suitable for mountain terrace measurement."
This is actually a copper right angle gauge with a movable angle protractor With the ball drop.
What kind of rule is something Wu Xuli and others have never seen before.
Lu Maoniang took Lu Qing to measure the first terraced field and used the torque to measure the height difference.
"The measurement of terraced fields is not complicated. Each layer is regarded as an independent platform, and then their height difference is measured, and finally the area is integrated. The area of a single layer is..."
"Aunt, please let it go," Lu Qing really didn't want to be hit again.
These formulas sound like the heavenly book.
Lu Maoniang was helpless and after a simple measurement, she quickly reported a number: "I remember that the Yunzhou Weekly Report mentioned that [the outer edge of each layer was indented by one foot and five inches as the boundary] . Since Hezhong County has been reborn as Duke Yun, it must naturally be determined according to Duke Yun’s rules. If there is no explicit requirement, everything should be imitated by Yunzhou.”
The Hong family was dissatisfied: "Yunzhou is Yun Zhou, Hezhong County is Hezhong County, how can we confuse it? "
Lu Maoniang sneered: "I couldn't before, but now I can! If you don't change your attitude, you will be eliminated sooner or later!"
"You..."
"Well said!"
Everyone looked in search of the voice and found Duke Yun and Li Mingde standing on the periphery. I don't know how long they had been here and how many had they seen? (This chapter ends)
