Li Jin resisted his shock, first read an orthodox historical record.
Now he is used to reading from right to left and upright.
From this look, Li Jin found that in fact, this world overlapped a lot with the ancient times of his previous life, but there were more brothers in terms of gender.
Moreover, although the names of each emperor are different, the major historical events that occurred are likely to be similar.
Li Jin breathed a sigh of relief. While listening to people around him discuss how important arithmetic is, he picked up a book on geography and read it.
It turns out that the capital of this era is also Yanjing, and Hongyan Village is in the north of the country. If you calculate it according to the map of the previous life, it is probably in the area of Shanxi and Gansu.
Li Jin is actually quite satisfied with the landforms here. After all, in ancient times, the traffic was not developed. Most places were dirt roads with potholes, and it was muddy when it rained.
If he was in Shu, it would take at least three months to go to Yanjing.
Most of the Shaanxi-Gansu generation are plains, and they are connected to the Weishui River, so the transportation is relatively convenient.
After Li Jin understood what he wanted to know, he went to look at Nine Chapters Arithmetic, and only went outside when he felt hungry.
The owner of the bookstore saw so many foreign students like this, and he didn't buy a copy after reading a day. He was not annoyed, and he smiled and watched the students go away.
Anyway, they will still come to buy arithmetic books in two days.
At this moment, if anyone is stingy with money and refuses to buy, then wait for the famous fall.
Anyone with a discerning eye will definitely come to buy it after considering it.
When Li Jin returned to the inn, Chen Xiran had already renewed the lease for the three of them. Renewing the lease in the day only requires ninety wen, which can save a little.
After seeing Li Jin, Chen Xiran hurriedly ordered food and said, "I'm going to be fainted from hunger, A Jin, can you gain something from this trip?"
Li Jin looked at him and said two words calmly: "Arithmetic."
Chen Xiran was about to jump up from the stool in the next second. He lowered his voice: "Is it really possible to take arithmetic exams? I thought the group of people in the teahouse framed me!"
Li Jin said: "Nearly half of the books on imperial examinations in the bookstore are arithmetic, so it should be fine."
He paused and continued: "Before the curfew, let's go buy books. About 90 candidates came to register today. The registration time is five days, and at least 500 people take the county exam.
There are not complete arithmetic books in our town, and I am worried that the county town will soon be sold out."
Chen Xiran could only follow Li Jin to speed up his meal, and then go shopping.
At this time, don't block the luck that 10% can't test arithmetic.
The shopkeeper of the bookstore saw the young and handsome boy coming back again and said, "You two want to buy books?"
Li Jin said: "Yes, I would like to ask the shopkeeper, which arithmetic books cover a wide range and are suitable for beginners?"
The shopkeeper said: "Since you asked so, then I won't blame you."
He turned to the bookshelf and picked up three books. "These three are all introductory books that count. This is our prefect. Now there is not much time before the county exam, and it is not easy to acquire one.
Let me tell you quietly that the books I have here were all prepared by the master of Yamen the day before yesterday."
The day before yesterday...that is, two days ago.
Li Jin thought, it means that the students in the county have only recently learned that they have to take the math test, so everyone is at the same starting point.
Hearing this, Li Jin stopped hesitating and chose one book with the widest coverage, and the other was compiled by the prefect.A total of three hundred essays cost him 600 essays.
In any case, the prefect must be given the face, and the county magistrate may also study the books of the prefect before asking the question.
Otherwise, this book would not be here.
Chen Xiran had no such worries and bought all three books at once.
Li Jin said, "You can't finish it again."
Chen Xiran: "I'll buy a peace of mind!"
Chen Xiran also wanted to buy the last one for Li Jin, but Li Jin waved his hand and refused, "The content is the same."
Introductory books are just, really don’t need too many.
Furthermore, as a medical student, he has studied advanced mathematics, linear algebra, and medical statistics for so many years, and he still has a solid foundation.
Moreover, this kind of introductory arithmetic exercises, in fact, Mr. Song has also discussed before.After all, mathematics is also part of the imperial examination.
It's a pity that Mr. Song said before: "I haven't taken the math test for so many years. You probably won't take the test this time. You just need to understand these."
Previously, Mr. Song said that the most difficult problem is probably the chicken and the rabbit in the same cage, but the description of the topic is rather obscure, and you need to read it several times to avoid misunderstanding the meaning.
But Li Jin felt that if he really passed the math test in the county test, he might have something to do with industry.
The book of Master Prefect lists some basic arithmetic solutions to purchasing problems in life.Of course, if it involves the Ministry of Industry and the Ministry of Households, it is even more esoteric.
This is no longer pure mathematics. The word'applied' should be added in front to become'applied mathematics'.
On the second day, Li Jin and Chen Xiran went to the bookstore together, and sure enough, everyone was looting books.
The book compiled by the prefect recommended by the shopkeeper yesterday is out of stock.
Huang Yiling sweated profusely in the winter: "We just came to register one day late, so why is this book gone!"
Zhou Qi was already bitter: "Without that book, we couldn't pass the exam this time."
Huang Yiling said: "No, no, let's go to the shopkeepers of various bookstores separately, or else we will buy the arithmetic manuscript at a high price of a few silvers."
Xu Zifan said: "Silver is not a problem. I'm afraid that other candidates will use us as competitors and will not let us copy any amount of money."
"This kind of arrangement is simply unreasonable. I came to register for a total of five days. This is just the next day. Why can't we even buy books!"
Huang Yiling squatted helplessly on the side of the road, "The people who signed up a few days later don't even know if they want to take arithmetic exams!"
Hearing what he said, Zhou Qi and Xu Zifan both showed despair in their eyes.
Although they know that they need to take a test of math, the book compiled by the prefect is the most important thing!If you can't buy a book, it's better not to know.
Chen Xiran watched a group of students come running, and ran away hurriedly after asking questions, suddenly frightened.
If Li Jin hadn't brought him to buy books yesterday, then the state of these people today is probably a true portrayal of them.
Chen Xiran said: "A Jin is still thoughtful."
Li Jin sighed and said, "I didn't come to watch the show today. Some of the bookshelves of the "Four Books" and "Five Classics" were recommended by county officials or prefects. There are so many books that you can't buy them.
Take advantage of today to write down important knowledge points, and go back and write carefully."
It's not that Li Jin didn't know the prophet, but after he bought the mathematics book from the prefect last night, he found a small seal on the back of the book.
He looked at the candle carefully and found the seal of the prefect.
But yesterday Li Jin saw a lot of books with this seal here, so he had this plan.
The annotations of each book have been explained in detail by Mr. Song. Now, looking at these books with seals, it is tantamount to "getting the title".
Therefore, Li Jin does not recommend Chen Xiran to buy the book directly.
All you need to do is to review the knowledge points you have received, and don’t make mistakes like "Sister I think" when you get it.
Chen Xiran has a good memory. Hearing this, although he didn't want to read a book, he also knew that Li Jin could not remember it alone.So he cooperated with Li Jin.
A short while before the curfew, Li Jincai and Chen Xiran walked out of the inner city.
They are leaving tomorrow. The two of them haven't even visited the four main streets, eight small streets, or even the many shops in the county seat. They spend the whole day in the bookstore.
Chen Xiran was a little melancholy, looking up at Jiaojiao Mingyue, "Exams are really difficult."
After reading the book for a day, Li Jin felt dizzy. He didn't like to say encouraging words, so he walked quietly under the moonlight.
Chen Xiran suddenly changed the subject: "I heard someone sing a song."
Li Jin was silent, thinking about going to the brothel at this time?
Li Jin said: "Tomorrow, I will take another day to go home. Let's take a good rest today."
In the end, Chen Xiran said, he knows which is lighter and heavier, and there is such a self-disciplined person by his side, he will not die.
Li Jin went back to take a bath, but Chen Xiran was stopped by Li Jin today and failed to go to the brothel, so he planned to go to sleep without taking a bath.
The master who drove the car was also considered an old man of the Chen family. Seeing that Chen Xiran grew up, he completely followed his young master's will for this, and he didn't even prepare foot wash.
After Chen Xiran took off his shoes, he thought for a while, worried that he would be disgusted by taking off his shoes with Li Jin in the car tomorrow, so he went downstairs to take a bath.
Li Jin also went to take a bath. He didn't worry about the exam, he had done his best to control himself, and he was left with the fate.
Instead, he was thinking about saving more money and buying a bath tub to go back another day.
But the home is not big enough, which is a problem.Li Jin no longer wants to buy a house recently, it is too expensive to afford it.
Earlier, I saved eleven taels of silver. For more than three months, I spent a tael on the grain, oil, salt, bamboo-leaf paper and burr paper for writing at home, and occasionally some small snacks.
This time, it will cost a couple of dollars to sign up for the test and buy books.
In the next month's exam, if there are five exams, it will be five days. He has to come at least one day in advance, so that it will cost at least two or two more.
The price of buying a house is still far short of thirty taels.
In fact, when it comes to making money, Li Jin thinks it would be much better to live in the county.
He can copy books to a bookstore. A book sells for 300 texts, and a copy of a book is only 120 texts.
The books at this time were so thin that Li Jin could finish copying in one day.
But there is a very practical problem right now, that is, houses in county towns are more expensive.
Li Jin didn't expect that one day he would be worried about buying a house.
Early the next morning, Li Jin practiced calligraphy and dictated after washing, but Chen Xiran hadn't woke up yet.
It seemed that staying at the bookstore for a day had a big blow to him. Li Jin planned to go out for breakfast first, but unexpectedly met the master driver.
He asked: "Master, when do you leave today?"
"It's okay to be late. The snow is gone, and the road is easy to walk. Just check out and leave."
Li Jin said: "Then I will go shopping in the inner city and come back before the time."
"all good."
In fact, he didn't have anything special, but he just wanted to buy some gadgets for the boy and the little bun.I don't know if the kid who would smile very happily when he saw Daddy talking to him in the past few days had he missed Daddy.
But Li Jin already missed them in his heart.
He thinks that both the left and the right have to wait until the end of the day, and it would be good to be able to find the gadgets that look good.
Bring gifts back to his two cubs.
