Otaku Engineer in Great Tang Dynasty Chapter 152: Lesson preparation

Anteroom.

"Brother Han, I wonder if your family Yuxi ever promised someone else?"

Ms. Li put down the tea cup in her hand and asked with a smile on her face. She should have discussed this matter with Han Yuxi's mother, but Han Yuxi's mother is no longer alive, so she can only talk to Han Lizheng.

Li Jingmo also looked at Han Lizheng. Mrs. Li told him Li Zexuan's thoughts last night.

Han Lizheng moved in his heart and replied: "The little girl hasn't been married yet."

Ms. Li smiled and said: "That's right, my family Xuan'er wants to marry Yuxi, I think these two children are also very fate, I think our family should be married, I don't know what the Han brothers think?" /

Han Lizheng was shocked. He didn't expect that Mrs. Li would even take the initiative to bring up this matter. He was still worried about his daughter's marriage.

"The young master is in a high position, and he is both civil and military. Naturally, he is a rare son-in-law. It's just a Han family, a small family, I'm afraid he can't afford it!"

Li Jingmo smiled and said: "Why did Brother Han say this? I don't have any opinion in the Li family. Moreover, Yu Xi is now a righteous woman in the Wing Kingdom. If you want to talk about Gao Pan, I am afraid that it is our Li family Gao Pan?" /

Han Li is hurriedly getting up and shirking: "What the master said, our Han family is just a countryman, so talk about how Gaopan. Since the master and the wife don't dislike, and the little girl and the young master are also very fond of each other, where is Han? The reason for opposition!"

Mrs. Li made a final decision: "Okay, two days later I will send the best matchmaker in Chang'an to the Han brothers' house to propose marriage!"

Han Lizheng also breathed a sigh of relief, he said, "Han will definitely be waiting at home!"

…………

Han Yuxi is still not his daughter-in-law now. Around Shenshi, Han Lizheng took Han Yuxi and left Li's house. Li Zexuan looked at Han Yuxi's beautiful back and felt lost.

I shook my head and went back to my small courtyard. By the way, I called Sambo and asked: "Sambo, I asked you to ask Fu Bo to make blackboards and chalk last time, are you ready?"

The first time I gave a lecture to Tiedan and Laner that day, he found that he was really unaccustomed to not having chalk and blackboard, so he wrote down the method of blackboard and chalk, and sent the three treasures to the workshop. Uncle makes a batch first.

Sambo replied: "Master, everything is done. The Fu Guan was sent over yesterday. When the young master was not free, he left the blackboard and chalk in the utility room."

In primitive society, China has discovered the lacquer tree and knows how to use natural lacquer made from the sap of the lacquer tree to make paint. In the Five Dynasties, Zhu Zundu wrote "The Classic of Lacquer", which is the world's earliest lacquer monograph. In the Tang Dynasty, lacquer of various colors was already available, so the manufacture of blackboards is not complicated.

The key is chalk. This can waste a lot of time for Fu Bo. He doesn't know how many times he has scolded Li Zexuan as a prodigal in his heart, only to play some useless things.

Li Zexuan nodded, and went to the utility room to the south alone. Pushing the door and entering, I saw several blackboards about two or three square meters in size and several boxes of chalk. Each box had hundreds of boxes. In addition to the white ones, there were even red, yellow, and blue ones.

Li Zexuan took a piece of chalk and drew a few strokes on a blackboard in front of him. He nodded in satisfaction. Although the chalk is not as delicate as the modern ones, the writing looks clear and barely enough. use.

Yes, Li Zexuan was planning to bring the blackboard and chalk on the way when he went to the Imperial College tomorrow. As for the raw material cost, he would not ask for Li Er, as he made a contribution to Datang's education.

...................

After reading the blackboard and chalk, Li Zexuan called Xiao Xi and went back to the study together. Xiao Xi sensibly helped him to polish his ink. Li Zexuan held his jaw, meditated for a moment, and started writing lesson plans. Since he is a "teacher" His fate is inevitable, so be the most powerful "teacher". This is exactly Li Zexuan's previous life style. You either don't do it or do it well.

Teaching mathematics in the Imperial College, definitely can't do the duck-feeding teaching as he taught to Tiedan. He cannot guarantee that the students at the Imperial College are as obedient as Tiedan. Many people find this course of mathematics difficult and boring, but as everyone knows, this course can also be very interesting.

At this time, he couldn't help but recall his elementary school math teacher, Liu Wenjie, in his previous life. His mathematics class was truly entertaining, lively and interesting, unlike the mathematics teacher of junior high school, high school, and university. Reading the scriptures in books has no meaning at all.

Li Zexuan recorded some very interesting basic math problems, and planned to save it for tomorrow. The first time in class, the interest of those bear children must be aroused, and the next class is afraid that no one will listen.

In fact, this is Li Zexuan thinking too much. In this era, the concept of respecting the teacher and respecting the Tao is very serious. As the saying goes, one day as a teacher and a lifetime as a father, for learning is more important than respecting the teacher. Basically, the teacher asks you to do it. What? You have to do it, otherwise your reputation will be completely stinky if you buckle off a deviant hat.

On the other hand, unlike before the Sui Dynasty, government-run schools were the exclusive domain of the children of the nobles. The Imperial College in the Tang Dynasty also made an exception to recruit a large number of underachievers. The desire for knowledge of these underachievers was very strong. Is it interesting? As long as you can learn something from it, they are willing to listen even if you speak lightly.

Half an hour later, Li Zexuan finished writing all the interesting stalks he could think of for a while. He stood up and rubbed his sore wrists. Xiao Xi quickly poured him a glass of water and handed it over, "Master, You have been tired for a long time, drink a glass of water!"

Li Zexuan smiled. He was really thirsty, so he took the cup, took a few sips, and then let out a sigh of relief: "Okay, finished writing, Xiao Xi, thank you!"

How long I wrote, and how long Xiao Xi grinds by the side. Grinding ink is also a very tiring job. After a long time, it is not easier than writing.

Xiao Xi smiled and said: "Master has worked hard. It has been a long time since Xiao Xi has seen Master take this seriously."

Uh, Li Zexuan is sweating, are you complimenting me or hurting me!

"Ahem, it's late, let's see how Tiedan and Lan'er are doing their homework."

………

Bringing Xiao Xi, Li Zexuan came to Tiedan and Lan'er's "classroom", and heard their noise from a distance.

"The answer to this question is one hundred and seventy-five, Tiedan, you made a mistake!"

"That's not right, Sister Laner, this question must be equal to one hundred and twenty-five, you can count it."

"Really? But I am so smart and cute, how can I make a mistake?"

Iron egg: "..."

Li Zexuan is speechless, his sister likes cocky as much as him.

"Tiedan, Laner, have you finished your exercises? I have to check it!"

Li Zexuan opened the door with Xiao Xi and said with a smile to the two children in the room.

"No, brother, check the iron egg first, and then check mine."

Lan Er quickly blindfolded her book to prevent Li Zexuan from reading it. She just figured it out. It seemed that the question she had actually calculated was wrong. Then she planned to let Li Zexuan check the iron egg first, and she still had a chance to correct it. .

This girl, secretly telling Tiedan the answer, she hasn't settled with her yet, but she has to make an inch of it. Forget it, who made her his sister. Li Zexuan shook his head, too lazy to care about Laner.

He took the iron egg homework and began to look at it. After a while, Li Zexuan nodded and praised: "All are correct, Tiedan, you did a great job!"

Tie Dan immediately became happy, Lan Er quickly corrected the answer, and handed the book to Li Zexuan: "Brother, you should check it after I finish writing!"

After that, she stood in front of Li Zexuan, her head held high, with an expression waiting for praise.

Li Zexuan is speechless, you have all right the standard answer, what else can I check?

"No need~ IndoMTL.com~ Lan'er, you passed the assessment. Tomorrow you will go to the Imperial College with your brother. Tiedan, you must keep working hard. As my personal disciple, you will not be allowed Go down!"

The iron egg felt Alexander, but still clasped his fist and said: "Master, don't worry, iron egg will not shame Master!"

Li Zexuan nodded in satisfaction, and went out.

"Hey, brother smelly, you haven't praised me yet! I did everything right!"

The iron egg covers his face.

Li Zexuan staggered and almost fell to the ground.
