Before she even stepped onto the steps of the gate of Gongyuan, Li Xiaonan heard the noise of laughter and laughter in the Gongyuan.
Gu Yan snorted vaguely.
What his uncle admired was Zhang Youchi's ability to stretch his nature, but every time he let it out, he couldn't take it back!
Li Xiaonan quickened her pace, and just as she passed Gu Yan, Wan Qing hurriedly took a step forward, grabbed Li Xiaonan, and quickly let go.
Li Xiaonan was pulled so hard that she staggered.
Gu Yan and Lady Wei Si looked at Li Xiaonan together.
Li Xiaonan steadied herself, hurriedly smiled, and signaled to Gu Yan to leave first.
Gu Yan glanced at Wan Qing sideways and raised his feet to move forward.
Madam Wei Si tried her best to hold back her laughter, and raised her hand to pat Wan Qing, who had her eyebrows lowered and her eyes lowered.
When Gu Yan raised his foot to cross the threshold, a clear and loud sound of a whip suddenly sounded, and the hustle and bustle in the Gongyuan suddenly stopped and was replaced by the sound of chaotic footsteps.
Li Xiaonan hurriedly took a step forward, held her breath, and slightly stretched her head to look into the Gongyuan.
Wei Xuezheng and others who were talking and waiting inside the door hurried forward and stood in a row with their hands down.
Wei Xuezheng looked at Li Xiaonan, who was next to Gu Yan, looking around with his head stretched out, and then looked at his nephew. He felt depressed and sad in his heart. He, a nephew who was talented, handsome and powerful, wanted to marry him.
Such a vulgar country girl!
Alas!
Li Xiaonan followed closely beside Gu Yan, turning her head to look at her as she walked.
The scholars attending the lecture stood in square formations on both sides of the road. In front of each square formation was a board that was exactly the same as the white board she had prepared. Next to the white board stood two scribes.
Li Xiaonan thought about Shi Gun's introduction. Well, they are just artificial versions of live broadcast classrooms. I don't know how effective they are.
Gu Yan glanced at Li Xiaonan from time to time, put his hands behind his back, and had an uncharacteristically cold face.
Alas, A-nan looked left and right without any dignity at all. He was afraid that if he continued to behave as kindly as before, A-nan would not be able to control the situation during his lectures and would cause chaos. These young scholars are the most courageous and do not know the importance of things.
.
Li Xiaonan looked at the scholars who were standing in a well-behaved manner and only dared to roll their eyes, and wanted to sigh, the rules here are too strict!
The lecture place seems to be a place specially used for lectures. It is a square pavilion, sitting on a stone base about two feet high. The door panels on all sides of the pavilion have been removed, and there are steps on all sides. There are steps under the steps.
There is a whiteboard.
Gu Yan stood at the foot of the steps and motioned for Li Xiaonan to come up.
Li Xiaonan held up her skirt and walked briskly up the steps. Wan Qing bowed her knees to Gu Yan and followed Li Xiaonan up the steps.
She is Li Xiaonan’s general assistant.
Gu Yan watched Li Xiaonan sit down in the middle of the pavilion, then turned and entered the temporary tent set up on the side.
Wei Xuezheng followed Gu Yan and muttered, "You are so ignorant and fearless."
Gu Yan looked back at Wei Xuezheng, "Don't worry."
In the booth on the stage, Li Xiaonan went straight to the point, "Now let's talk about the first question of island arithmetic."
Li Xiaonan paused, and Wan Qing hurriedly took out a roll of paper marked with one word from the box that had been placed in the middle of the cabinet. Each of the four boys handed a piece of paper to the steps on all sides. Wan Qing opened the piece of paper covered in the middle of the cabinet.
Red silk on the white board.
After Li Xiaonan finished speaking, she listened with her ears straight up and listened to the surrounding water waves, which seemed to be okay...
Mr. Shao and Ni Rushi stood in the phalanx of scholars, listening to the voice coming over, and stretched their heads to look at the whiteboard.
The clerk next to the whiteboard had already seen the icons beforehand, took a quick look at them, and quickly drew them with a charcoal ruler.
The picture is very simple, a triangle with a diagonal line and two straight lines in the middle.
Ni Rushi frowned and took a closer look. Mr. Shao nodded and smiled. It was a good deal, but the island calculation was too simple.
"Everyone sitting here must already know how to solve this problem, so I won't go into it. This problem uses similar triangles. Let's talk about the determination of similar triangles and how to determine whether two triangles are similar.
Triangle, how to prove..."
Ni Rushi looked stunned and subconsciously looked at Mr. Shao. Mr. Shao stretched his neck and stared at the whiteboard one after another
The triangles drawn are clearly out of step.
Wei Xuezheng became confused when Li Xiaonan skipped a sentence. However, he had never been good at Ge Zhi. Wei Xuezheng twisted his head and asked Professor Ge Zhi from Fu Xue, "Which book does what she talks about come from?"
Professor Ge Zhi frowned and shook his head.
"Then do you understand?" Wei Xuezheng looked at Professor Ge Zhi.
"It's okay, don't say anything." Professor Ge Zhi frowned.
"Tell Miss Li to be slower." Gu Yan calmly ordered Shi Gun.
He has experienced how profound A-nan is in character.
In the cabinet, Li Xiaonan paused and asked, "About parallel lines, do you have any questions?"
There was a moment of silence in the crowd, and someone raised his hand, "Students think visual inspection is enough."
Wan Qing immediately looked at Li Xiaonan, smiled like a flower and threw herself at the two paper tubes.
Pieces of thin and transparent bamboo shadow paper were passed from all directions, with straight lines drawn on the bamboo shadow paper.
Immediately afterwards, another piece of tissue paper covered with dark and light color blocks was passed out again. The scribe followed the instructions and placed the color block tissue paper under the bamboo shadow paper.
After a moment of silence, screams sounded and the scene became chaotic.
"Now, can you still do visual inspection? Seeing is not necessarily believing." Li Xiaonan said with a smile.
Wan Qing smiled hard, stood on tiptoe slightly, and looked at the chaos in the audience.
Wei Xuezheng stared at the parallel straight lines that instantly twisted and twisted after putting the tissue paper on them. He took a step forward, pulled down the tissue paper, and looked at the lines that instantly straightened back. He waved his hand to signal the scribe to put the tissue paper back, and looked at the moment.
The lines became confused again, and he grabbed Professor Gezhi, "What's going on? How could this happen?"
"I don't know either!" Professor Ge Zhi stepped forward, lifted up the bamboo shadow paper, looked at it, put it down, looked at it again, and lifted it up again.
"Why do our eyes see wrongly when we put those colors on the mat? Why are we in the mirror opposite to our left and right? If we can truly understand the island calculation, we can understand why."
Ni Rushi stared at the lines that were sometimes straight and sometimes chaotic. Hearing Li Xiaonan's words, he was filled with confusion. He looked at Mr. Shao, whose brows were knitted into a ball. Knowing that he definitely didn't understand, he still couldn't help but ask, "Mr.
What's going on?"
"I heard there are handouts." Mr. Shao answered the wrong question.
Gu Yan stood at the door of the tent, looking at the confused and confused scholars around him with a half-smile...
He knew they couldn't understand!
In the tent, Wei Xuezheng grabbed Professor Gezhi again, "Do you understand?"
"Something has been learned, something has been learned. Don't say anything!" Professor Ge Zhi slapped Wei Xuezheng away.
Wei Xuezheng glanced sideways at Professor Ge Zhi, who was sweating on his forehead, and walked to Gu Yan, "I didn't expect that the island's arithmetic is so profound. I see..."
"Whether island sutra calculation is advanced or not depends on whether you meet an advanced person. When you told me about it, it was not so profound." Gu Yan retorted rudely.
"That's it, my uncle is not good at graciousness." Wei Xuezheng said with a dry smile, "I mean, why don't you want everyone to read the lecture notes. Miss Li's lectures are too bright to cast a shadow. You see, even Lao Liu
I didn’t understand."
Gu Yan looked sideways at Wei Xuezheng, and for a moment, he said yes.
What he wanted was this effect, and he couldn't bear to let Grandma talk for a whole day!
Li Xiaonan's lecture only lasted for half an hour, and she and Wan Qing moved to the lobby behind. They stood on the window sill and looked at the classrooms on both sides. In the middle of the courtyard, groups of scholars were led by professors or seniors, facing the whiteboard.
Eyebrows furrowed.
"Is it that difficult?" Li Xiaonan looked at Mrs. Wei Si and asked.
"My father has urgently delivered a handout to the Hanlin Academy. There is a Gezhitang in the Hanlin Academy." Lady Wei Si bowed slightly, very respectfully.
The Wei family respects true scholars the most.
Li Xiaonan held her chin and sighed with a heavy heart. If what she has learned today is too rare, then the things she plans to write will be in vain if no one can understand them.
She should first think of a way to write the foundation
