People in Datang have been expelled from school

Chapter 595
Leaving the construction of the factory to Yan Liben, Li Zheng returned home and took out the geography from the system library. There are many mineral deposits in Tubo, 23 mine deposits have been discovered, and [-] tons of gold mines have been found. Mine [-] tons.

Li is taking note of the locations of these deposits.

And circle it on the map.

Songtsan Gampo guarded such a big treasure, but didn't know how to use it.

Li Zheng sighed.

Li Zhi came with a pile of books, "Teacher, what a violent exile."

Little Si also struggled to put down the books. Her short legs and arms obviously couldn't carry too many books. There were only a dozen books, and Little Si was sweating profusely from exhaustion.

Li Zheng came back to his senses and said, "Did I just speak?"

Li Zhi put down the booklet and said: "These are newly printed books by the book printing workshop. They are all books on mathematics, and many of them were compiled by Daoist Li Chunfeng."

Li Zheng glanced at these several mathematics books, and Li Chunfeng wrote every mathematical algorithm into a book.

Opening it and looking at the content, Li Zheng said: "The writing is too piecemeal, too much theory, too little practice, the most important thing in mathematics is to do the problems."

After listening, Li Zhi said: "The teacher means that Taoist Li Chunfeng's writing is not good."

Li Zheng nodded, "First of all, what is described above is the personal narration of Daoist Li Chunfeng. They are all theories, and the practicality of mathematics is very high."

Li Lizhi happened to have business matters to tell Li Zheng, and when he came to the door of the study, he heard Li Zheng and Li Zhi talking, and stood at the door and listened carefully.

The little sizi said again: "Then what will be considered good."

Li Zheng shook the fan in his hand and said: "Truth comes from practice, and knowledge can be applied. For example, these mathematics books are divided into several books. Although the classification of Daoist Li Chunfeng seems simple, it is missing a very important point. .”

Xiao Si listened to Li Zheng's words, although he didn't understand what he said, he thought it was amazing.

Li Zhi said, "The most important point."

Li Zheng said: "There are actually many applications of numeracy in daily life, such as geometry problems and unit conversions, and application problems and geometry problems are combined as a topic, and examples from life are used to do math problems."

Li Zhi thought for a while and said: "Students understand, it is called mastery, mastery of all the algorithms they have learned."

The child can be taught, seeing the little si's eyes staring at him with admiration, Li Zheng's old face is red, he is doing mathematics in primary and secondary schools, and he was often beaten up by Olympiad questions back then.

Picking up these books again, Li Zhi said: "It's a pity that Master Li Chunfeng's hard work for several months will be in vain again. The students will go and tell what Master Li Chunfeng said."

Li Zheng shook his fan and nodded.

Seeing Li Zhi and Xiao Sizi leave the house, Li Lizhi also walked into Li Zheng's study, "Recently something happened to our business."

Li Zheng nodded while drinking tea, "What is it?"

Li Lizhi said with a sad face on the side: "Many people are selling our products. For example, a pot of spirits is bought from our Jingyang for a penny, but when you buy it, you sell it for a penny. The previous paragraph There are promotions from time to time, and many people have stocked up on our products."

Holding a teacup, Li Zheng said, "Actually, the solution to this problem is very simple."

Li Lizhi looked up at Li Zheng, "What should I do?"

Li Zheng said in a low voice: "I still need your father's help in this matter."

"Father?"

"That's right, for a trademark certified by the royal family, it is best for your father to inscribe a word, only the products sold by our Jingyang signboard are genuine."

"Then everyone else is selling fakes?" Li Li asked.

"I didn't say that?"

Hearing this, Li Lizhi became even more puzzled.

Li Zheng patiently said to Li Lizhi: "To use the brand effect, we in Jingyang have our own brand in Jingyang, and the spirits that are sold out for the second time, who knows if they have a second processing, whether they have been watered, will only be smashed It’s just our own brand.”

Li Lizhi nodded.

Li Zheng picked up his pen and wrote the word Jingyang, "In the future, all our products will be engraved with the word Jingyang and packaged well. Only what we sell in Jingyang is the real product. Of course we don't say that others sell our drinks Not a fake."

Li Lizhi nodded after listening, "In this case, the business of those merchants hoarding our goods will definitely suffer."

Li Zheng nodded, "That's right."

Now that there is a way to break the business, Li Lizhi's ambition was aroused again, "I'm going to write a letter to my father."

Li Zheng still nodded, "Go, it's best if your father has mentioned it."

As soon as he walked to the door of the study, Li Lizhi said again: "By the way, it cost another [-] guan to collect food recently, do you want to continue to collect it?"

Li Zheng looked out the window while drinking tea and said, "Take it, keep it."

Li Lizhi nodded and took Xu Hui to work.

Li Zhi put a pile of books intact in front of Li Chunfeng.

Li Chunfeng looked at the sent book and asked strangely: "Why did you take it back again?"

Li Zhi said: "The teacher said that Taoist Li Chunfeng's writing method was wrong. The teacher said that the most important thing in mathematics is practicality. It is not enough to only do the theory without doing the questions, and it must be mastered."

"Practical?"

Li Zhi nodded, "Daniu taught us that we always start with doing the questions, and we learn as we go, so we can learn quickly."

Li Chunfeng flipped through the books he wrote and said, "It's true that the poor have made some omissions."

After speaking, Li Chunfeng buried his head and continued to write.

Xu Jingzong has been watching the movement of Dali Temple in Chang'an these days.

His Majesty actually decreed that Chang Sun Chong should come for interrogation, this news surprised many people.

Now that the position of Minister of Dali Temple is vacant, Xu Jingzong bribed several officials to inquire about the news.

In Dali Temple, Zhang Sunchong led a group of jailers from Dali Temple to bring out Xinxin.

"How are you doing in prison?" Chang Sun Chong asked.

Tied to a chair, he said with satisfaction: "The life in the prison is not bad, I can sleep until dizzy every day, and I can eat and drink for nothing every day. I am afraid that the son of the eldest grandson does not know how difficult my life in Tubo is. Those hard-to-swallow foods make me worry about sleeping every day, and I haven’t had a solid sleep for a long time, thanks to my grandson, I can sleep peacefully.”

Chang Sun Chong said: "Stop talking nonsense, let me ask you, who is the person you have been communicating with?"

Xin shook her head, "I don't know."

Seeing that he refused to speak, the jailer punched him in the stomach, and shouted, "Mr. Changsun asked you something? Are you going to say it or not?"

Coughing continuously, Yixin endured the pain and looked at the jailer, "You are just trying to curry favor with Changsun Chong, so there is no need to use such force. If something happens to me, do you think Mr. Changsun will reward you or drive you out of Dali Temple."
