In the spring of the eighteenth year of Jian'an, Hanzhong County.

The people of Hanzhong once again spent a year of abundant food and clothing.

At this time, spring ploughing is about to begin, and the construction of Hanzhong Vocational Skills Training School has begun.

During this period, Jiang Wei also came to the Marquis Mansion of Hanzhong many times to discuss the revision of the textbook with Lin Chuan.

"Berjo, the content of mathematics is very important, and there are uncertain aspects in this regard, so you can ask an arithmetic master to guide you."

In the study, Lin Chuan was discussing with Jiang Wei about mathematics textbooks.

The four operations of addition, subtraction, multiplication and division in elementary school are naturally not difficult, but when it comes to practical applications, Jiang Wei still needs to ask Lin Chuan for help.

Lin Chuan felt that his suggestion was likely to be inconsistent with the current knowledge system, so he suggested that Jiang Wei find an arithmeticist.

"Okay, student understands."

After Jiang Wei knew the direction of the solution of the mathematics textbook, he took out the Chinese textbook and asked Lin Chuan to take a look.

Lin Chuan opened Jiang Wei's revised Chinese textbook and read it carefully, and found that there was no problem.

Then Jiang Wei took out a science textbook, which inspired Jiang Wei the most.

Although Lin Chuan has already deleted the content that is too advanced, such as electricity-related knowledge, magnetism-related knowledge, etc.

However, the breadth of the content contained in the science book still shocked Jiang Wei.

For the book of science, Jiang Wei had no way to revise it, so he put this book at the end to consult Lin Chuan.

"Teacher, this science book is really all-encompassing, many knowledge students have never heard of it, and they really don't know how to revise it!"

Lin Chuan watched Jiang Wei put the science textbook in his hand, and said helplessly.

"Let's put aside the science textbook for now, and this textbook will be revised by the teacher himself."

Lin Chuan, who had no good way to solve this problem for a while, had to take it over personally.

So Jiang Wei left the science textbooks and the revised Chinese textbooks in Lin Chuan's study, and then Jiang Wei took the mathematics textbooks and prepared to ask some arithmetic masters.

After Jiang Wei left, Lin Chuan began to flip through the science textbook on the table.

The current science textbooks have already undergone a deletion, and after careful consideration, Lin Chuan decided not to continue to delete the science textbooks.

Because there are many contents in science textbooks that involve the knowledge and understanding of the world, if you continue to delete them, it is better to cut this course directly.

Although Lin Chuan only wants to cultivate a group of talents who have the ability to be responsible for the production base, he still hopes that these children will have room for continued improvement in the future.

Science textbooks are a key that can help them understand the world correctly.

In the end, Lin Chuan decided to come to the children of Hanzhong Vocational Skills Training School in person to give this science education class!

After Jiang Wei received orders from Lin Chuan to find the arithmetic masters, he began to inquire through the scholars of Hanzhong County where there were people who were proficient in the "Nine Chapters of Arithmetic".

When Jiang Wei was preparing to revise the mathematics textbook, he planned to refer to the content in "Nine Chapters of Arithmetic", but although he had an understanding of "Nine Chapters of Arithmetic", if he wanted to integrate the mathematics textbook with "Nine Chapters of Arithmetic", Jiang Wei did not have that strength now.

After many inquiries, Jiang Wei finally learned from a scholar that there was an arithmetic master in Yangzhou, whose name was Zhao Shuang, and the word Junqing.

Zhao Shuang is now in his first year, he has had in-depth research on Zhang Heng's astronomical work "Lingxian" and Liu Hong's "Qianxiang Calendar", and he is a well-known astronomical and arithmetic master in Yangzhou.

So Jiang Wei decided to go to Yangzhou in person and ask this Zhao Shuang to revise the mathematics textbook.

Before Jiang Wei left for Yangzhou, he came to the Hou Mansion to explain the situation to Lin Chuan.

"Teacher, the students have learned that there is an arithmetic master in Yangzhou, whose name is Zhao Shuang, and the word is Junqing."

Lin Chuan was very happy after hearing Jiang Wei say that he had found arithmetic, but he had no impression of Zhao Shuang, a great mathematician of the Eastern Han Dynasty, and did not remember that this Zhao Shuang was a great mathematician of the Eastern Han Dynasty who explained the Pythagorean theorem in detail with a Pythagorean square diagram!

"Boyo, you did a good job, write to the branch in Yangzhou now, and ask them to invite Zhao Shuang to Hanzhong."

"Teacher, the scholar who recommended Zhao Shuang for students once said to students that this Zhao Shuang's achievements in arithmetic are very high, and the students are afraid of neglecting this arithmetic master, so they plan to go to Yangzhou in person with mathematics textbooks and ask him to help revise them."

Jiang Wei told Lin Chuan his thoughts, and Lin Chuan also felt that it made sense after hearing it, so he agreed that Jiang Wei would go to Yangzhou.

Now the road from Hanzhong to Yangzhou is also a cement straight road, and it doesn't take much time.

After Jiang Wei got Lin Chuan's consent, he quickly packed his bags, prepared the carriage and took the guards to Yangzhou.

At the same time as Jiang Wei went to Yangzhou, he sent a letter to the shopkeeper of the Yangzhou branch, asking him to confirm Zhao Shuang's residence.

The journey from Hanzhong to Yangzhou was safe and sound, and Jiang Wei came to the Yangzhou branch.

Shopkeeper Li, who was in charge of the Yangzhou branch, warmly received Jiang Wei and his party.

In the most luxurious box on the second floor of the Yangzhou branch, Shopkeeper Li was telling Jiang Wei about Zhao Shuang's residence and personality.

"Lord Jiang, Zhao Shuang lives in Zhao Mansion in Yangzhou City, not far from the branch, and I will go with you to visit Zhao Shuang then."

Jiang Wei nodded after listening to Shopkeeper Li's words and said:

"It's best to have Shopkeeper Li with you, and it's hard for Shopkeeper Li."

Shopkeeper Li smiled when he heard this:

"This is a matter within the next division, by the way, Lord Jiang, Zhao Shuang usually lives in a simple place, and especially likes to study astronomy and arithmetic. I don't know what Lord Jiang came to Yangzhou to find Zhao Shuang for this time? It's good to be prepared in the next place. ”

After Jiang Wei learned that Zhao Shuang liked to study astronomy and arithmetic, he was much more sure of asking Zhao Shuang to help revise the mathematics textbook.

Then Jiang Wei smiled at Shopkeeper Li:

"Shopkeeper Li, I came to Yangzhou this time in the hope that Zhao Shuang could help revise the mathematics textbook of Lord Hou of Hanzhong."

When Shopkeeper Li heard that Jiang Wei had come to Yangzhou this time, he had been ordered by Lin Chuan, and he became even more concerned about this matter.

The two then chatted about the development status of the Yangzhou branch, and Jiang Wei came to the hotel on the third floor of the chamber of commerce to rest.

Shopkeeper Li came to the most prosperous market in Yangzhou City to choose gifts for Zhao Shuang.

The next morning, Shopkeeper Li and Jiang Wei took gifts and went to Zhao Mansion to meet Zhao Shuang.

After the two came to the Zhao Mansion, the subordinates of the Zhao Mansion heard that it was the shopkeeper Li of the Hanzhong Branch and the Jiang Master of Hanzhong County who came to visit, and directly invited the two to the lobby of the Fuzhong.

After Zhao Shuang heard the report of his subordinates, he quickly tidied up his robe and came to the lobby to meet Jiang Wei and Shopkeeper Li.

It's just that Zhao Shuang wondered in his heart, could it be that the Hanzhong Chamber of Commerce saw that he was good at arithmetic, so he wanted to ask himself to be the bookkeeper?
