Sound familiar?
Miaoyin looked at Yun Zheng with a dark face.
Does it just sound familiar?
He is quite forgetful!
Miaoyin reminded in a low voice: "He is one of the three great scholars in the world...oh, no, he is one of the two great scholars!"
One of the two great scholars?
Yun Zheng was stunned for a moment, then suddenly reacted.
He said the name sounded familiar!
So it’s this person!
I just don’t know if it’s that Wu Dao.
...
...
Or is it a duplicate name?
However, not everyone dares to have the same name as this great scholar.
This random naming will lead to criticism.
Considering that Lan Hua said that her cousin was half-student of Zhang Huai, it can be basically confirmed that the Wu Dao in front of us is the famous Wu Dao.
Thinking of this, Yun Zheng immediately stepped forward and said, "No need to be so polite, everyone! I have heard of Elder Wu's great name for a long time, but I didn't expect to meet him in this way today."
"I dare not, I dare not! I am just a corrupt scholar." Wu Daoke said politely.
"Mrs. Wu is too modest."
Yun Zheng smiled politely.
"Thanks to your help today, my niece was saved from injury. Please come in and rest for a while."
As he spoke, Wu Dao slightly stepped aside and raised his hand to invite him.
"Mr. Wu, please!"
Yun Zheng exchanged some polite words and followed Wu Dao into the courtyard.
Shen Kuan ordered most of the troops to stay outside, and he went in with a few others.
When I entered the yard, I found that there was a different world inside.
Although this yard is not antique, it is full of flowers and plants, including a few clusters of bamboo, which are rare in the north.
The whole yard looks simple and elegant.
It is in line with Wu Dao's identity.
After sitting down in the yard, Wu Dao introduced the people of the Wu family to Yun Zheng and the others.
Wu Dao's son and daughter-in-law were among them.
Yun Zheng nodded and smiled at everyone, then introduced Miaoyin and Shen Kuan to them.
Everyone hurriedly bowed to Miaoyin and Shen Kuan.
This etiquette is quite thoughtful.
Yun Zheng looked around and asked with a smile, "I see your yard is a mixture of old and new. Did you just move here?"
Wu Dao replied: "I moved here last August."
"I see!"
Yun Zheng smiled and asked, "Do you have any relatives in Juping?"
"No."
Wu Dao shook his head gently: "I just have an old friend in Juping."
Miaoyin was slightly surprised and asked curiously, "Why didn't Mr. Wu live in Juping City, but instead lived in the countryside outside the city?"
The question Miaoyin asked was also the question Yun Zheng wanted to ask.
Living in the city would definitely be much more convenient.
Although this place is not far from Juping City, it is still somewhat inconvenient.
After all, Wu Dao is a great scholar of the time. He should have the money to buy a property in Juping, right?
Wu Dao smiled and said, "I have always liked quietness. Now that I am old, I like quietness even more."
"Is that so?"
Yun Zheng laughed in silence, "We have disturbed Elder Wu's peace today."
"No, no, today it is all thanks to the prince for helping Huaer."
Wu Dao smiled politely and waved at Lan Hua, "Hua'er, go and prepare the wine and food with your aunt first. We have distinguished guests coming today, so we must entertain them well."
Wu Dao and Gao Shizhen seem to be two extremes.
Gao Shizhen is arrogant and likes to take advantage of his seniority.
Even in front of Yun Zheng, he still acted arrogantly.
But Wu Dao was a little too polite.
Being polite is just an appearance, but in reality it actually means being distant.
It seems that Wu Dao doesn't seem to like me very much!
"yes."
Lan Hua agreed and bowed to Yun Zheng and the others, saying, "I'll take my leave now."
Then Lan Hua's aunt and cousin also bowed and left.
The maid next to them wanted to serve tea, but Lan Hua's cousin Wu Qingyang took the teapot from the maid and poured tea for Yun Zheng and Miaoyin himself.
"Thank you very much."
Yun Zheng nodded and smiled at Wu Qingyang, "I heard from Miss Lan that Elder Zhang gave you an arithmetic problem, and it stumped you?"
“Yes, yes!”
Wu Qingyang nodded repeatedly, "I just wanted to ask the prince for advice, is it convenient?"
"Just say it."
Yun Zheng smiled.
"Wait a moment, Your Majesty."
Wu Qingyang said this and immediately got up and ran towards his room.
Not long after, Wu Qingyang came out with a piece of paper.
Wu Qingyang spread the paper flat in front of Yun Zheng.
Looking at the contents on the paper, Yun Zheng couldn't help but widen his eyes.
There is a large square on the paper, which is divided into three areas: A, B and C.
The shaded part is A, which is a small square. The area of B is 4, and the area of C is 7.
There is a note next to the question, which ultimately asks how big is A's piece of land.
"Is this the question that Elder Zhang gave you?"
Yun Zheng looked at Wu Qingyang in surprise.
He originally wrote several pages of mathematics content for Zhang Huai, but much of it was far beyond the level of mathematics of that era.
Without the corresponding theoretical basis, Zhang Huai would certainly not be able to research many things.
The fact that he was able to study this topic shows that Zhang Huai was really studying the things he wrote!
Moreover, the research is quite profound!
What a pity for this old scholar!
If Zhang Huai had lived a few more years, he might have been able to lay a solid foundation in mathematics!
"This question was indeed proposed by the late Mr. Zhang."
Wu Qingyang replied: "Two years ago, when Lord Zhang was seriously ill, I went to the Imperial City to visit him. Before I left, Lord Zhang gave me this question and asked me to bring it back and give it to my father to solve..."
Wu Qingyang explained to Yun Zheng in detail the origin of this question.
When he left Zhang's house, Zhang Huai specifically reminded him that if Wu Dao really couldn't solve it, he could go and ask Yun Zheng for help.
But Wu Dao solved it with just a casual glance.
Later, Wu Qingyang felt that there was something wrong with this question, so he directly measured the land according to the method in the question.
However, the measured results are very different from those calculated mentally.
At this moment, Wu Qingyang became even more confused.
He had been calculating for a long time to figure out what the problem was.
But I still haven't figured it out.
Because of this question, he often couldn't sleep at night.
After hearing Wu Qingyang's words, Yun Zheng couldn't help but secretly thank Zhang Huai.
Naturally, there was no need for Zhang Huai to show off his advanced knowledge to Wu Dao.
Zhang Huai deliberately asked this question, probably because he wanted to send Wu Dao to his side.
Unfortunately, Wu Dao did not come to find Zhang Huai as Zhang Huai wished.
But no matter what, he still wants to thank Zhang Huai for his hard work.
When he returns to the imperial city one day, he will definitely go to Zhang Huai's tomb to pay homage.
"Don't embarrass yourself here!"
Wu Dao glared at his son angrily, "You are the one who got into a dead end. Don't bother the prince here!"
"Dad, I'm not at a dead end!" Wu Qingyang argued, "I've measured it many times, and the results are very different from what you said! The questions asked by Elder Zhang are definitely not as simple as you think!"
Yun Zheng nodded slightly and asked with a smile: "Do you think that Plot A should be three acres?"
