Judging from Li Zhen's appearance, Li Shimin knew very well that her thoughts were all on Lishan. In addition to missing her grandpa, he might also be thinking about finding her imperial sister and her two little girls from the same family.
Her beauty is no longer small, and it would be outrageous to think about running to other people's homes every day and spreading the word.
Seeing her stubborn attitude, Li Shimin was very worried, fearing that this girl would not be able to control her in the future.
"After I have taken care of the political affairs these days, I will take you to Lishan Mountain to pick up your grandpa and return to the palace to celebrate New Year's Eve."
Li Lizhi raised her head and asked, "How many days will it take?"
With another long sigh, Li Shimin said melancholy: "Three or two days."
"Well, the daughter will go back to accompany her mother first."
Her steps jumped with joy, and the aggrieved and stubborn attitude she had just had disappeared.
Li Shimin picked up a meat bun and found that the bun was already cold. He was holding a memorial from Zhongshu Province in his hand.
We have to send troops to the Duhufu, build the Hexi Corridor, and prepare for next year's imperial examination and Cheng Qian's marriage. Even the construction of Jiucheng Palace can only be put on hold.
As an emperor, he found that the money on hand was not enough.
Taxes from Guanzhong have been recovered, and taxes from more remote places are still on the way.
Suddenly I thought of my son-in-law, Zhang Yang, whose papermaking workshop has been almost two years old and is still the same unless he expands his workshop.
His life must be very prosperous now. If he really wants to make contributions to the country, he should return Lishan to me.
One day he will be hanged in front of Chengtian Gate and all his family property will be swallowed up.
Lishan, Zhang Yang sneezed loudly.
Shangguan Yi warned: "The county prince should pay attention to the cold and warmth."
Zhang Yang was holding a compass in his hand and comparing the angle of the sun. He tightened his clothes, "I'm obviously wearing warm clothes."
Use your compass to check the angle of the sun and walk back and forth along the Weishui River.
Now there is a row of wooden stakes standing on the stage. Zhang Yang marked each wooden stake and used the shadow of the vertical ground to mark the line. He watched the movement of the wooden stake's shadow under the sun and confirmed the position of the direct sunlight.
Shangguan Yi was very curious about this compass, "I heard that observing the stars at night is the skill of strange people. Zhang Shangshu can also deduce the stars during the day?"
Zhang Yang explained: "I only have a superficial understanding of astrology. I just used the sun, moon and stars to make some annotations."
"Chu Suiliang has been in the village for half a month. I heard from the children in the village that he is often absent-minded when teaching."
"Absent-minded?"
"Yes." Shangguan Yi said again: "I have also observed that this person often comes to Lishan to teach. After finishing teaching in the library, he goes to Mr. Ouyang Xun to ask for calligraphy lessons."
Zhang Yang frowned and said, "Is it the winter solstice now?"
The winter solstice will be in two days.
Yuan Tiangang's compass is still not convenient to use, and its judgment of solar terms is not accurate, and it needs to be improved.
In the absence of so many precision instruments, the derivation of orientation and time of year is often a rough number.
Only after the calendar is determined can the solar terms be determined.
It is a very heavy workload to use this compass to re-derive the calendar. It is not only necessary to record the changes in solar terms within a few years, but also to look at the records of the past few decades.
This has nothing to do with the current need for the daughter-in-law to calculate the latitude and longitude.
Of course, the more knowledge you can acquire, the better.
Having too many skills doesn't overwhelm you, it's better to learn more.
The sundial needs to calculate the inclination angle according to the longitude and latitude, and use this calculated inclination angle to place it obliquely to the plane.
Use the inclination angle of the sundial to make up for the altitude angle between the latitude line and the sun, so that it is flush with the equator. Only in this way can it be regarded as a normal and functional sundial.
Shangguan Yi asked in confusion: "Why did Zhang Shangshu ask about solar terms again?"
Zhang Yang was still looking at the compass, "This is related to calculating longitude and latitude. You may not understand it after I told you. In fact, where we are can be expressed by longitude and latitude, so that we won't get lost even if we go out."
"It's not difficult to use stars to tell the direction. What's difficult is to infer the distance. What are these longitudes and latitudes?"
Shangguan Yi has read a lot, so knowledge in this area will probably not be difficult for him.
As soon as the words changed, I almost forgot why I came to Xianhou this time.
Zhang Yang found a clean stone and sat down, looked up at the position of the sun, and then looked at the shadow of the wooden pile.
"County Marquis, do you want to arrange other work for Chu Suiliang?"
It was his biological father Chu Liang's arrangement that allowed Chu Suiliang to come to Lishan.
There are not many people like Chu Suiliang who have certain attainments in calligraphy.
Of course you should use it well if you can use it.
Withhold his wages?
Maybe his family simply doesn't appreciate the one hundred yuan a month that Lishan gives.
When the shadow coincided with the marking, Zhang Yang quickly recorded the position. Using the calculated angle, the height of the wooden pile and the length of the shadow, he calculated the angle that needed to be tilted, so that the sum of them was 180 degrees.
.
This math problem is not too difficult.
Shangguan Yi watched Zhang Yang take out a thin rope and tie it vertically to the stone, and then use another piece to align it with the middle end of the rope.
Niu Chuang's inner coat was very thick, and his outer coat was fully stuffed and patched, with even a lot of conspicuous threads.
Everyone is wearing this in this cold winter. As for the cotton clothes at home, they are only for children, and adults are reluctant to use them.
He put his hands in his sleeves and shrank his neck in the cold wind. He leaned forward and whispered: "Brother Shangguan, why is the county prince doing this?"
"This is measuring the slope. Old and experienced craftsmen can know how much the wall or foundation has shifted with just this measurement. This is wisdom."
Niu Chuang nodded with a confused expression. He had seen another skill that he had never seen before.
After a long moment of silence, I watched Zhang Yang holding a short charcoal pen and writing words that others could not understand on the stone platform.
Niu Chuang asked again in a low voice: "Is this easy to learn?"
Shangguan Yi shook his head and smiled bitterly, "It's difficult to learn with Brother Niu's basic skills. If you can master some mathematical operations, it will be easier to master."
When Niu Chuang heard that it was numerology, Niu Chuang's smile became even more embarrassing. Let alone numeracy, he couldn't even recognize the words now, so he could only learn one or two words from time to time from the children at home.
】
"Does Brother Shangguan know this skill?"
"It's not difficult."
"When the children in the village learn it, a certain family won't have to learn it." For Niu Chuang, it took more than thirty years, and it is easier said than done now.
This chapter is not over, please click on the next page to continue reading! Instead of thinking about learning this, it is better to look to the children of the future.
"Brother Niu, I've confirmed the location and it's ready to be released."
After hearing Zhang Yang's words, Niu Chuang waved to the people who were ready to carry the sundial onto the stage.
Shangguan Yi was surprised by Zhang Yang's speed. It would take at least a day for a craftsman with more experience to calculate.
After thinking about it again, I felt that this matter would not be difficult for Zhang Yang at all.
With his level of mathematics, it only takes a moment to calculate the inclination of the sundial.
Zhang Yang held the angle, and Niu Chuang and others gently lowered the sundial, which equaled the angle of the wooden stake. Zhang Yang straightened the string to compare the error between the two.
After confirming that it was correct, he nodded to indicate that it could be fixed.
The sundial is as big as a millstone and has a slender iron pestle passing through it. It can be regarded as a serious clock in the village.
I took another look at the booklet and went through the calculation process. I only felt relieved after confirming that there were no problems.
God never lets people arrange the weather as planned. The day after the sundial was made, it snowed heavily again in Guanzhong.
The plan to calculate latitude and longitude can only be shelved.
The little bear always likes to roll in the snow. Xiao Wu scolded it more than once, and it became even more unscrupulous.
Because every time the bear came back to the house after rolling in the snow, it would be wet and would lean on her body, which made her very distressed.
If Xiao Wu falls behind, it will hide behind Xu Hui again.
While making Xiao Wu angry, he went to Xu Hui to comfort him.
Inexplicably, I feel like this bear is starting to lose its temper.
After Li Yue glared at it, he obediently returned to the roof.
No matter whether he was messing around in front of Xiao Wu or Xu Hui, Little Bear only dared not act recklessly in front of the real mistress of the house and lay motionless on the ground.
When Xiao Wu was unhappy, he could only say a few harsh words.
If the mistress is unhappy, it will starve.
Steam eggs with bacon and add some home-grown spinach.
Zhang Yang was packing up the meat and vegetables at home, and there were still a few green onions left in the backyard. The green onions would freeze in such a cold weather, so he dug some out by the roots and put them in the warehouse aside for cultivation. If these green onions don't grow well,
, we have to wait until next spring to have onions to eat.
Aunt Yang came quickly and said, "The County Marquis Zou Guogong and the Supreme Emperor are here."
Zhang Yang looked outside the hospital and saw that the teacher and Li Yuan had already walked to the door. He hurriedly washed his hands and went out to greet them.
Li Yuan stroked his beard and said, "It's dinner time. I passed by here and came to see you."
While talking, Li Yuan noticed Xu Hui again, "What a handsome girl."
Zhang Yang introduced: "This is Xu Xiaode's daughter, Xu Hui."
Xu Hui saluted sensibly, "I have met two elders."
"Xu Xiaode? I have heard about everything going on in the court. It is also time for Erlang to rectify the administration of officials."
While talking, Li Yuan took Zhang Gongjin and sat down at the dining table.
"I didn't know that Grandpa Huang was coming. I didn't prepare any meat or vegetables at home, so I asked my aunt to make arrangements."
Li Yuan waved his hand and said: "It doesn't matter, as long as my family can feed themselves."
Zhang Gongjin glanced at the little bear and said, "This animal is getting taller and taller."
Hearing this, Zhang Yang took out a piece of dried meat, and the little bear stood up so greedily that it reached the height of his waist.
After picking up the dried meat, he sat under the eaves and ate it with relish.
"This animal was raised to be docile, but it's a pity that it was supposed to be a filial piety to the mountains and forests, but instead it became..."
"It has become my family's sacred beast, and it can also bring some prey from the mountains." Zhang Yang took over the words and said.
Seeing how casually he spoke, Zhang Gongjin asked again: "I heard that you have been reading some ancient books these days?"
"Your Majesty asked me to read the books of sages and hoped that I would become a good person."
Li Yuan snorted coldly: "I'm right, I knew he would say that."
Zhang Gongjin took out a piece of silver cake and said, "I am willing to admit defeat."
Li Yuan chuckled and said, "It seems that what he is reading is a book by a sage, but in fact he is reading a book that is highly respected by aristocratic families, and he has the intention of dealing with aristocratic families. It's a pity that Xu Xiaode didn't understand it and was taken advantage of by your kid."
"It turns out that the Emperor made a bet between me and the teacher."
Li Yuan did not deny it. He took the bowl of hot tea handed by Li Yue and drank it leisurely, "Who do you think your teacher is? He was one of the most relied-upon counselors of Erlang in Prince Qin's Mansion. He secretly made plans and killed people.
No less than your boy."
Speaking of that year, Zhang Gongjin also said with emotion, "It's a joke."
Li Yuan emphasized: "Both of you, master and disciple, are not good people. You surrendered to Wang Shichong many years ago, and later you followed me to quell rebellions in various places. You captured the three counties of Chuqiu, and then entrenched yourself in Yucheng. When you went to Henan Province, you seemed like
To appease them, we secretly captured the descendants of strong men from all over the country and used them as threats, thus stabilizing the situation in Henan and Hedong."
"Zhang Yang, you are young and strong-willed in the court. I can also see that you are humble and often ask for advice. Yan Shigu offended you, but you did not care about it. Gao Xian pushed you away, but you did not take revenge.
Changsun Chong had conflicts with you, but you never paid attention to it, and even the nobles scolded you and spurned your Honglou."
"You have so many enemies at such a young age. As your teacher, Duke Zou is very worried. Sometimes I wonder if you are really so open-minded or if you don't take your peers seriously."
Zhang Yang bowed slightly and said, "The teacher and the Emperor are worried."
Li Yuan snorted coldly: "You kid is fooling around outside alone. Duke Zou is worried about you. You should ask him more about anything in the future before he is buried."
What this meant was that Li Yuan saw clearly that the conflict between Xu Xiaode and Lu Chengqing was unknown to others, but Zhang Gongjin could definitely see who was taking advantage of whom.
"Teacher, Xu Xiaode and the students can't see those people living in such a prosperous life in this world. This is not taking advantage, but our hearts are pursuing justice."
Zhang Gongjin said in a deep voice: "I told you about someone before, do you still remember?"
"The teacher is talking about Wang Gui?"
Zhang Gongjin closed his eyes and breathed steadily, nodded slowly and said: "Since His Majesty came to the throne, Wang Gui has been following Your Majesty. That year, there was a shortage of officials in the court, so His Majesty asked Gao Shilian to take charge of the Ministry of Personnel and preside over the appointment and removal of officials. Later, he asked Wang Gui
I will temporarily take the position of servant, and then give it to Yongning County Duke."
"When he was young, this man didn't value fame and fortune, but he was recommended by Li Gang to join the army. He was a member of the Wang family in Taiyuan. He was a child of an aristocratic family, but he didn't have the aura of being a child of an aristocratic family. He always lived alone, and he couldn't bypass local clans when he held the imperial examination and became an official.
, local powerful people, and aristocratic families from all over the country, these are all obstacles."
"I heard from Shangguan Yi that the matter between you and the prince was just a small fight. If you want to deal with the aristocratic family, you have to go see Wang Gui. He may be able to help you."
Zhang Yang added: "But does Wang Gui care about the world, or does he care about the aristocratic family?"
Zhang Gongjin sighed, "Back when Emperor Wen of the Sui Dynasty was still in power, he was implicated by his uncle and wanted to be beheaded several times. He didn't know who he offended in the clan. When he was in trouble, no one from the Taiyuan Wang family came to help him.
.”
Xiao Wu and Xu Hui both entered the house and did not dare to disturb the conversation in the courtyard.
Zhang Yang said clearly: "It turns out that the teacher has a plan."
Li Yuan said with emotion: "You are his only disciple. All three sons are under your care and their lives are not long. If they don't plan for you, who will they do for?"
"What you are saying is that the teacher is worried only because of me."
"You kid, don't think about retiring at thirty. A teacher will end with resentment, and a disciple's life will not last long."
