Fei Ruhe's situation was similar. He was flipping through "Algorithms" in his hand, and his thoughts had drifted into the sky. Arithmetic in hell was more difficult than Sishu.
Finally, Fei Ruhe couldn't help but say, "Mr. shit, he hasn't returned for a long time, he must have a stomachache. I don't think we need to learn arithmetic today."
"Yes, yes, there is no need to study anymore." Fei Yuanjian quickly agreed, he came to make friends, not to study hard together.With his knowledge base, if he really wants to make progress, he must first go back to the Mongolian Museum to re-read children's books.
Xu Ying didn't dare to speak. Although she was not so scared anymore, she still had a rift with the rich young master.
Zhao Han smiled and said, "Then you go to the bamboo forest to practice martial arts."
Fei Ruhe, who had already stood up, sat down again after hearing the words, hehe smiled and said, "If you don't go, then I'll stay."
Fei Ruhe was also guilty of being a thief, and he also had a share in posting big-character posters, so he didn't dare to get along with Fei Yuanjian alone.
"Haha, then I'll stay and study too." Fei Yuanjian smirked.He had nowhere to go at all. He had offended too many classmates in the past, and if he was alone, he would be easily beaten by a group.
Fei Chun ran back and forth several times, and finally brought everyone's meals.
After a while, Pang Chunlai also returned to the classroom, picked up his chopsticks and said, "Learn while you eat. This method of arithmetic is more practical than the study of classics. From now on, whether you are a local official, marching to fight a war, or managing your family business, Arithmetic is definitely useful."
"Yes." Fei Ruhe, Fei Yuanjian, and Fei Chun all frowned.
Xu Ying sat upright, eagerly waiting to learn new knowledge.
As for Zhao Han, he didn't say a word the whole time, and immersed himself in familiar terms with various ancient terms.
For example, "length" and "width" are often called "wide" and "from".If you don't understand this, no matter how good the math is, it's useless, you can't even understand the question.
Another example is the timing unit, hour, moment, more, and point.
12 hours a day, 2 hours a day, everyone knows that.
It is a little troublesome to remember. It used to be 100 quarters a day, and Western clocks came, and a day was changed to 96 quarters.I heard that in Beijing, some people suggested that it be changed to 108 ticks. Anyway, it's a mess.
In addition, there are very common time units such as seconds, mans, and suddens.
And Zhao Han was surprised to find that there was a "Zhou" in ancient China, and it had been used for 2000 years.
The normal week has 7 days and the leap week has 8 days. During the Qin and Han Dynasties, it was used to determine the working day, and the court officials only worked 6 days a week.Just because of the troublesome conversion of flat and intercalated, it is not used much later, but it is more intuitive and convenient in the [-]th of each month.
There is also the word "week", which refers specifically to the seventh day of the seventh lunar month, and is derived as a wedding date.
The week is approaching, the wedding day is approaching.
Zhao Han was already familiar with mastering arithmetic, but then he was reluctant to learn it, and pestered Pang Chun to explain various units and terms.
≡⊥=‖_×
Can you see what the above means?
The arithmetic version of 3622.14 (the decimal must be half a space short).
In fact, as long as you get used to it, it is no different from Arabic numerals, it is nothing more than a different symbol expression.
……
Seeing that Zhao Han only pays attention to professional terms and doesn't like to learn basic arithmetic, Pang Chunlai smiled and asked a question: "Zhao Han, can you figure it out?"
It's really that Zhao Han is progressing too fast, and he is obviously tired of learning, so he has to beat him with a difficult debut!
Xu Ying, Fei Ruhe, Fei Yuanjian, and Fei Chun, the four of them read the question curiously, and then they looked dumbfounded.
The content of the topic is roughly as follows: "On the front line, there are only 28 shi of rations left, and the daily consumption is 7 shi. If the food supply is transported, it can be reached on the 25th, and 1 shi is consumed every day on the way. Please, how much food do you need to transport so that the front-line soldiers can last for 90 days? ?"
Xu Ying pondered the problem-solving method carefully, and his mind was a mess. He had just started to learn multiplication.
Fei Ruhe couldn't help but say, "Sir, aren't you making things difficult for people?"
"I didn't ask you to solve the problem again," Pang Chunlai looked at Zhao Han with a smile, "If you can't solve it, you will be honest and practical in the future!"
Zhao Han did not answer the question immediately, but asked, "After the rations have been delivered, will they stay on the battlefield and wait for [-] days, or will they return the same way? The question is vague and there are three different answers.”
Pang Chunlai laughed: "It's rare to think carefully, you can figure out all three solutions."
Zhao Han picked up the straw paper, set the number of grains to be X, and then began to formulate the equation.
One-dimensional linear equation, elementary school questions only.
Three quick answers came out.
All the schoolchildren were instantly shocked. Whether they were good students or bad students, they all looked at Zhao Han with admiration.
Pang Chunlai snatched Zhao Han's calculation draft, a string of mysterious codes made him dizzy, and modern equations were heavenly books to him.
"Which national character is this?" Pang Chunlai asked in confusion.
Zhao Han asked tentatively, "Do you know Xu Guangqi, sir?"
Pang Chunlai nodded and said: "Xu Guangqi, although I have never seen this person as a teacher, or even don't know his name, but he has heard his name for a long time. After the great defeat of Sar Hu, he was ordered to train a new army in Tongzhou. Now that the new emperor has ascended the throne, According to the Imperial Court News, he has been reinstated as an envoy of the Qing army."
The Qing army is to check the situation of the army, including officers, soldiers, training, food and salaries, ordnance and so on.
Xu Guangqi's current job is to clean up the Ming army.
Since Pang Chun said he hadn't seen it before, Zhao Han could just talk nonsense.
Without blinking, Zhao Han opened his mouth and said, "There is a missionary in the West, named Matteo Ricci, who came to Ming Dynasty with "The Elements of Geometry". Xu Guangqi translated this book, and my father was fortunate to read it during his lifetime. These figures are all from the West. come."
"Let's talk about it." Pang Chunlai was immediately interested. He asked the schoolchildren to do the questions while eating, while he asked for Western arithmetic.
Zhao Han wrote Arabic numerals and various operation symbols, and marked the Chinese characters one by one below them.
Pang Chunlai did not like Arabic numerals, but was surprised by the convenience of Western operators.However, if you want to introduce those operator symbols, you have to match Arabic numerals.
It is impossible to express the arithmetic, because the "4" in the arithmetic is exactly the same as the multiplication sign, and the "2" is similar to the equal sign.
Pang Chunlai could only forcibly compare the two characters, and then looked at Zhao Han's equation.
"This Heavenly Yuan Technique!" Pang Chunlai slammed the table.
Xu Ying and San Fei, holding chopsticks in their hands, looked over stupidly, they couldn't understand the silly meaning at all.
Tianyuan Technique is the formula.
Pang Chunlai said again: "This is Taixi's Tianyuan technique, which only lists one yuan. Can you solve the two yuan, three yuan, and four yuan?"
Zhao Han asked curiously, "Can you solve the four yuan with a calculator?"
Pang Chunlai shook his head and said, "Some people know it, but I don't. It is said that Zhu Shijie, a great scholar of arithmetic in the Yuan Dynasty, once created a four-element solution. But I have only read his "Enlightenment of Arithmetic Science", and I have no chance to see his "Four Yuan Jade Mirror". ” book. Don’t say so much, let me come up with a question, and you can solve it with Taixi’s Tianyuan Technique.”
Soon, a topic came out.
Zhao Han solved it with a two-dimensional linear equation and handed over the solution: "Sir, please take a look."
Pang Chunlai was not familiar with Arabic numerals, so he could only check the calculations slowly, then clapped his hands and praised: "Miao Zai, wonderful!"
Using arithmetic to solve binary linear equations is actually very fast, and the efficiency is not inferior to that of column equations.
However, the problem-solving process of calculating Tianyuanshu is more complicated to express on paper, and it is far less simple than equations.
If it is a two-dimensional secondary problem, the Yuanshu that day is even more complicated!
Pang Chunlai laughed: "This technique is ingenious, let me teach you as a teacher."
Students teach teachers?
Xu Ying and San Fei were even more stunned, feeling that Zhao Han was really amazing!
Pang Chunlai said to the four of them, "You also learn together."
Since then, their arithmetic learning speed has doubled compared to before, and even Fei Yuanjian felt it was easier.
Not stupid after all.
Fei Yuanjian's relationship with everyone has always been delicate.
Every day is like sticky candy, reading, practicing martial arts, and learning arithmetic together.Xu Ying accepted him quickly, but the others had troubles in their hearts, and Ruo Li Ruo Li always had reservations.
The winter solstice is approaching.
The martyrdom archway has been repaired, but the court's approval has not yet come down.
This thing needs to be approved by the government at all levels, and then given to the emperor in the name of the emperor.
But by the end of the Ming Dynasty, basically just give money.
If you are slow, look for the magistrate, and if you are fast, look for the imperial censor.After sending it to the court, the emperor didn't care at all, the cabinet was directly thrown to the Ministry of Rites, and officials of the Ministry of Rites could approve it with money.
The Chastity Arch is also exclusive to the rich!
Because the imperial court only allocated 30 taels, which was not enough to set up the memorial archway, and more money was needed for the up and down management.People who have no money and no status, no matter how chaste and powerful they are, they will not be able to erect archways unless the magistrates are doing it for political achievements.
Ritual cannibalism?
Sorry, if your family has no money, you are not even eligible to be eaten.
Chapter 041 [Winter Solstice Chinese New Year]
The winter solstice is a big day, and generally there are three days off.
Pang Chunlai took out some money and asked Zhao Han and the others to go to the town to buy vegetables, planning to celebrate the festival together.He also called Xu Ying's family and said that they were helping to cook rice and vegetables, and it was nothing more than a change of method.
Arriving at Hekou Town, the trio's pavilion is not far away, and it is the newly established Martyr's Pavilion.
"It's too urgent," Fei Ruhe said.
Zhao Han muttered, "Don't be in a hurry, the reputation of the Fei family depends on it."
Compared with the towering and gorgeous three-person pavilion, the strong girl archway is simply shoddy.Just carved the words, and the rough edges of the stone were not trimmed, so they hurriedly erected by the river.
For the remaining details, the craftsmen put up scaffolding, chisel and grind slowly, and may continue to grind for a year or two.
The procedure was not done.
On the county government's side, they have already requested the official list, but the petition document has not yet entered the capital, and it will have to be approved by the court at the end of next spring at the earliest.
Everything is like a child's play, and the government is too lazy to pursue it.
A few decades ago, the approval of chastity archways was still strict, but now it is showing a trend of flooding.Half of the [-] chastity archways in the Ming Dynasty were built in the late Ming Dynasty. Anyway, if you have the money to apply for construction, it will be approved for you.
In the Qing Dynasty, there were more than one million chaste martyrs. During the six years of 290, there were an average of more than 3000 martyrs in each county!
It is more like a comparison between families, and it is also a manifestation of the political achievements of local officials.
Taking Huizhou as an example, the number of virtuous women: 2 in the Tang Dynasty, 5 in the Song Dynasty, 21 in the Yuan Dynasty, 710 in the Ming Dynasty, and 7098 in the Qing Dynasty.
This kind of hurricane and sudden data, which started in the late Ming Dynasty and flourished in the Qing Dynasty, can give a glimpse of the abnormal development of etiquette.
Fei Ruhe said in a low voice, "That thing won't be revealed, right? Fei Yuanjian is next to us every day, does he have any doubts? I feel guilty when I look at him now."
"Yeah, I'm also very scared." Fei Chun echoed.
Zhao Han smiled and asked, "What are you talking about? I didn't do anything wrong, so I couldn't understand."
Fei Ruhe was stunned for a moment, then nodded again and again: "Yes, yes, I don't understand, I haven't done anything."
"Master, I'm still afraid." Fei Chun tangled.
Fei Ruhe immediately scolded: "You didn't do anything bad, you are afraid of shit!"
Fei Chun quickly shut up.
Xu Ying asked curiously, "What are you talking about?"
"It's nothing," Zhao Han explained with a smile. "They peeked at the little widow taking a bath and were almost caught on the spot."
"I didn't, don't talk nonsense!" Fei Ruhe denied.
Zhao Han smiled and said, "Right, if you don't admit it, you won't."
Fei Ruhe shouted injustice: "I really didn't peek at the little widow taking a bath."
……
Probably during the Chenghua and Hongzhi years, the social economy began to develop greatly, and the common people were also keen to celebrate the festival.Three days before the winter solstice, the shops will be closed one after another, and everyone will be greeted and delivered, which is as lively as the Chinese New Year.
But Hekou Town could not go out of business. It is the thoroughfare of eight provinces and a prosperous commercial transportation center.
When he got to the town, Zhao Han found that all the traders and pawns were wearing new clothes, at least they had to put on clean and good clothes.
Many porters carried the burdens and sent them to cargo ships or inns.
These burdens are filled with gifts, commonly known as "winter solstice plate".Small families and small households can just carry the food box, and it is a good idea to communicate; rich and powerful families have to carry a burden, and the gifts are too shabby and they will lose face.
There are always some foreign merchants who cannot go home during the winter solstice. Among business partners, they are courteous and considerate.
Therefore, the restaurants in the town specialize in "Winter Solstice Dishes Gift Packages", which are divided into different price grades, and also provide door-to-door service.
