Li Jin held back his shock and took out an orthodox historical record first.
Now he is used to reading from right to left, standing vertically.
Looking at it, Li Jin found that in fact, this world has a lot of overlap with the ancient times in his previous life, but there are more brothers in terms of gender.
Moreover, although each emperor's name is different, the major historical events that occurred are likely to be similar.
Li Jin breathed a sigh of relief, and while listening to the people around him discussing the importance of arithmetic, he picked up another geography book to read.
It turned out that the capital of this era was also Yanjing, and Hongyan Village was in the north of the whole country.
Li Jin was actually quite satisfied with the landforms here. After all, traffic in ancient times was underdeveloped, and most places were dirt roads with potholes, and it was even more 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 connected to the Wei River, the transportation is more convenient.
Li Jin understood what he wanted to know, read Jiu Zhang Arithmetic again, and went out only when he felt hungry.
The owner of the bookstore saw a lot of foreign students like this. He didn't buy a book after reading a book for a day. He was not annoyed, and watched the students leave with a smile.
Anyway, they will come to buy arithmetic books in two days.
At this moment, whoever is stingy with money and refuses to buy it, then wait for the famous to fall into the mountains.
As long as you are discerning, you will definitely buy it after considering it.
When Li Jin returned to the inn, Chen Xiran had already renewed the lease for the three of them. It only cost 90 cents to renew the lease during the day.
After seeing Li Jin, Chen Xiran hurriedly ordered food and said, "I'm going to faint from starvation, A Jin, did you gain anything from this trip?"
Li Jin looked at him and calmly said two words: "Arithmetic."
Chen Xiran was about to jump up from the stool in the next second, and he lowered his voice: "Is it really possible to take an arithmetic test? I thought the group of people in the teahouse framed me!"
Li Jin said: "Nearly half of the imperial examination books in the bookstore are on arithmetic, so it should be fine."
He paused and continued: "Before the curfew, let's go to buy books. There are about 90 candidates who came to register today, and the registration time is five days. At least 500 people take the county exam.
There are not many arithmetic books in our town, and I am worried that the books in the county will be sold out soon. "
Chen Xiran could only follow Li Jin to speed up the meal, and then went to buy books.
At this time, don't try to block the 10% luck of not being able to test arithmetic.
The shopkeeper of the bookstore saw the young and handsome boy coming back again and said, "Can you two buy books?"
Li Jin said, "Yes, may I ask the shopkeeper, which arithmetic books have a wide coverage and are suitable for beginners?"
The shopkeeper said, "Since you asked that, then I won't lie to you."
He turned around and went to the bookshelf and picked up three books, "These three are all introductory books for arithmetic, and this is what our prefect advocates to compile. Now that the county exam is short, it is not easy to acquire one.
Let me quietly reveal to you that the books I have here are all prepared by the yamen master the day before yesterday. "
The day before yesterday... that is, two days ago.
Li Jin thought, it means that the students in the county town have only recently learned that they need to take the math exam, so everyone is starting from the same starting point.
Hearing this, Li Jin no longer hesitated, and chose a book with the widest coverage, and the other was edited by the prefect. A book of 300 words cost him 600 words in total.
In any case, the prefect's face must be given, and maybe the county magistrate will also study the books of the prefect and then come up with a question.
Otherwise this book would not be here.
Chen Xiran did not have this concern, and bought all three copies at one time.
Li Jin said, "You can't finish reading it."
Chen Xiran: "I'll buy a peace of mind!"
Chen Xiran also wanted to buy the last book for Li Jin, but Li Jin waved his hand and refused, "The content is similar."
It's just an introductory book, you really don't need much.
Furthermore, as a medical student, he has studied advanced mathematics, linear algebra, medical statistics, etc. for so many years, and he still has the foundation.
Besides, this kind of introductory arithmetic exercise was actually taught by Mr. Song before. After all, math is also part of the imperial examinations.
It's a pity that Mr. Song said before: "I haven't taken the math exam for so many years, and you probably won't take the exam this time. You just need to understand it."
The most difficult problem that Mr. Song has talked about before is probably the chicken and the rabbit in the same cage, but the description of the topic is rather obscure, so you need to read it several times to avoid misunderstanding the meaning.
But Li Jin felt that if he really took the math test in the county exam, he would probably be involved in the industry.
The prefect's book lists some basic arithmetic to solve purchasing problems in life. Of course, if it involves the Ministry of Industry and the Ministry of Household, it is even more esoteric.
This is no longer a simple math, and the word 'applied' should be added in front of it to become 'applied math'.
The next day, Li Jin and Chen Xiran went to the bookstore together, and sure enough, everyone who came was madly grabbing books.
And the book edited by the prefect recommended by the shopkeeper yesterday has long been out of stock.
Huang Yiling was sweating profusely running in the winter: "We didn't come a day late to sign up, why is this book gone!"
Zhou Qi's face was already bitter: "Without that book, we wouldn't be able to pass the exam this time."
Huang Yiling said, "No, no, let's go separately and ask the shopkeepers of the bookstores, or else we will pay a high price of three taels of silver to buy the arithmetic manuscript."
Xu Zifan said: "Silver is not a problem, it's just that we are afraid that other candidates will take us as competitors and will not let us copy them no matter how much money they give."
"Such an arrangement is simply unreasonable. It takes five days to sign up. We are only the second day. Why can't we even buy books!"
Huang Yiling squatted on the side of the road helplessly, "The people who signed up in the next few days didn't even know that they had to take an arithmetic test!"
Hearing what he said, Zhou Qi and Xu Zifan both showed despair in their eyes.
Although they knew they had to take the math test, the book compiled by the prefect was 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 then hurried away after asking, suddenly scared.
If it wasn't for Li Jin taking him to buy books yesterday, then the state of these people today would be a true portrayal of the two of them.
Chen Xiran said, "A Jin is still thoughtful."
Li Jin sighed and said, "I'm not here to watch the fun today. Some of these "Four Books" and "Five Classics" bookshelves have been recommended by the county magistrate or the prefect.
Take advantage of today to write down important knowledge points and go back and write them down. "
This is not Li Jin's prophetic prophet, but after he bought the math book issued by the prefect last night, he found that there was a small seal on the back of the book.
He looked at the candle carefully, only to find the seal of the prefect.
And yesterday, Li Jin saw a lot of books with this seal printed here, so he had this plan.
Mr. Song has already explained the annotations of each book in great detail. Looking at these books with seals now is tantamount to 'taking a question' and 'guessing a question'.
Therefore, Li Jin does not recommend Chen Xiran to buy books directly.
You only need to review the knowledge points you have acquired, and don't make mistakes like 'my sister, I think about it' when you pass the test.
Chen Xiran has a good memory. Hearing this, although he didn't want to read a book, he knew that Li Jin alone could not remember it. So he cooperated with Li Jin.
A little while before the curfew, Li Jin and Chen Xiran walked out of the inner city.
They were leaving tomorrow. The two of them had not even visited the four streets, eight small streets, or even numerous shops in the county town, and spent the whole day in the bookstore.
Chen Xiran was a little melancholy, looking up at the bright moon, "Exams are really difficult."
Li Jin also felt dizzy after reading a book for a day. He didn't like to say words of encouragement, so he just 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 we have to take a day's car to go back, so let's have a good rest today."
In the end, Chen Xiran just said that, he knows which is more important, and with Li Jin, such a self-disciplined person by his side, he will not die.
Li Jin went back to take a bath, but Chen Xiran couldn't go to the brothel because he was stopped by Li Jin today, and planned to sleep without taking a bath.
The driver of the car is also an old man of the Chen family. Watching Chen Xiran grow up, he completely followed his young master's wishes, and he didn't even prepare water for washing his feet.
After Chen Xiran took off his shoes, he thought about it, worried that he would be disgusted by taking off his shoes with Li Jin tomorrow, so he obediently went downstairs to take a shower.
Li Jin also went to take a bath. He was not worried about the exam.
Instead, he planned to save more money and buy a bathtub to go back another day.
But the problem is that the family is not big enough. Li Jin has not thought about buying a house recently, it is too expensive to buy.
I had saved 11 taels of silver before, the food, oil, salt, bamboo leaf paper and rough edge paper for writing at home for more than three months, and occasionally some small snacks, which cost a tael.
This time, it will cost you a tael to sign up for the county test and buy books.
For the exam next month, if there are five exams, it will be five days. He has to come at least one day in advance, so it will cost at least two or two more.
It's still a lot less than thirty taels of money to buy a house.
In fact, when it comes to making money, Li Jin thinks it will be much better to live in the county seat.
He can copy books for bookstores, sell a book for 300 wen, and hire someone to copy a book for 120 wen.
At this time, the books were thin, and Li Jin could finish copying them in one day.
But there is a very real problem right now, that is, houses in the county seat are more expensive.
Li Jin never imagined that one day he would worry about buying a house.
Early the next morning, Li Jin practiced calligraphy and read silently after washing up, but Chen Xiran still hadn't woken up.
It seemed that spending a day in the bookstore yesterday hit him hard. Li Jin planned to go out for breakfast first, but unfortunately met the driver.
He asked, "Master, when are you leaving today?"
"It can be later, the snow has subsided, and it is easy to walk on the road. Just check out and go."
Li Jin said, "Then I'll go to the inner city for a walk and come back before this time."
"all good."
In fact, he didn't have anything in particular, but he just wanted to buy some gadgets for the boy and the little bun. I don't know if the little boy who sees his father talking to him and smiles very happily these days has missed his father.
But Li Jin already thought of them in his heart.
He thought that he would have to wait until now, and it would be good to be able to find gadgets that he liked.
Bring gifts back to his two cubs.
