Gu Xu found a spot on the sidewalk near the railing.
This side of the railing is the sidewalk, which is relatively wide. There are some shops on the opposite side, and behind the railing is the driveway.
He spread out the folding table and hung the whiteboard he had prepared on the stainless steel railing beside the square.
It says on the whiteboard: Guidance on high school and elementary school mathematics problems, five yuan for big questions, three yuan for intermediate questions, and two yuan for small questions. The price of special questions is negotiable.
There happened to be a stone bench in front of the railing. He placed the small table in front of the stone bench, and the venue was finally set up.
Gu Xu sat at the table, looking calm and composed.
He looked at Lan Ruosi: "Little porridge, come and sit!"
Lan Ruosi felt uncomfortable all over, as if everyone was looking at her.
Gu Xu was very calm about her reaction.
His little daughter-in-law was afraid of strangers, and he already knew that when they first met.
Now, put her in front of so many people, and she does panic.
"If you don't want to sit with me, you can sit on the stool next to me!"
Before Gu Xu came, he didn't expect that there would be a bench here.
He brought several stools, two of them for himself and some for people who came with questions.
Gu Xu opened a stool and motioned to her: "Come here, little porridge, I'll accompany you, don't be afraid!"
Don't be afraid!
Lan Ruosi repeated in her mind...
yes!
Gu Xu is here, what am I afraid of?
She suddenly seemed to have a little more courage.
She sat on the small stool next to Gu Xu.
"You're passing by, don't miss it, come and take a look!" Gu Xu began to shout.
Lan Ruosi was shocked, her face turned red and her heart beat faster, "Why are you still shouting?"
She didn't expect it at all.
"Don't be afraid!" Gu Xu reassured, "When doing business, of course you have to shout so that people will stop."
Lan Ruosi subconsciously became more nervous. She really didn't know what would happen next second.
While the two were talking, a white-haired old man and a seven or eight-year-old little girl came towards them.
"Brother, can you do this question?" The little girl's voice was childish and cute.
Gu Xu smiled: "What question? Show it to my brother?"
The little girl pointed to the question on the homework book: "This!"
"This is so simple! There is a formula for the nine-square grid. Wear nine shoes and one, three on the right, seven on the left, two and four with shoulders, eight and six as the foot, and five in the center."
The little girl looked confused.
"Brother, show it to you and you will understand." Gu Xu quickly wrote down the formula and numbers on it and explained it to the little girl.
The little girl looked happy: "Thank you, brother, I understand."
Seeing his granddaughter happy, the old man was also very happy: "Young man, how much does it cost?"
"Grandpa, not much, just one dollar!"
The old man took out a dollar and gave it to Gu Xu.
"Goodbye, brother!" the little girl said goodbye to Gu Xu happily.
Gu Xu looked at Lan Ruosi proudly: "How about it? Just keep it simple!"
The expression on Lan Ruosi's face was complicated, and her heart was full of mixed emotions: disbelief, doubt, joy, surprise...
After a while, another father and son came over. Both father and son were a little fat, and they looked like they were carved from the same mold.
The father glared at his son: "Why are you so stupid? You can't even answer elementary school questions."
The son was unconvinced: "You have the nerve to accuse me, but you still don't know how to do it!"
The father sternly said: "I don't know how. I can find someone to teach you. If someone teaches you, but you still don't know how, you are stupid!"
As they talked, the two came to Gu Xu's stall.
The son took out a study material from his schoolbag, opened it to the middle, pointed to a question, but said nothing.
The father glared at him again: "You kid, why are you so rude? You can't even speak!"
Gu Xu smiled and said: "Uncle, don't worry, he is still young."
The son's expression became much more relaxed, and he turned to glare at his father, saying, "Look, everyone knows I'm still young."
Gu Xumo smiled: "Little brother, don't worry, my brother will teach you..."
Gu Xu looked at the question and read it out: "The snail climbs up the manhole. It climbs 9 decimeters during the day and slides down 7 decimeters at night. It reaches the ground on the fifth day. How deep is the manhole?"
Lan Ruosi blurted out: "17 meters!"
Gu Xu immediately turned to look at her: "How about you come?"
Lan Ruosi shook her head hurriedly, her head like a rattle.
"You gave the answer so quickly. If you didn't explain it, would it be a bit burying your talent?"
"I, I..." Lan Ruosi said nothing.
Lan Ruosi had done this question when she was in elementary school, and it left a deep impression on her.
However, at that time, her snail climbed slower, climbing three meters during the day and sliding down two meters at night.
Unexpectedly, after so many years, they are still doing this question.
The methods for both questions are the same.
The difference is that this snail now climbs faster than the one back then, and can climb 9 meters.
Gu Xu knew that Lan Ruosi was interested.
When speaking in front of a top student, her thinking will naturally be stimulated.
It's like singing in front of a singer, painting in front of a painter, or acting in front of an actor, their cells will beat unnaturally.
But she is still a little scared.
The more this happens, the less you can force her, you can only let her slowly open her heart.
To win a woman's heart, you must not force her.
You can only boil the frog in warm water, let her slowly lower her guard against herself, and slowly and unconsciously give her heart to you.
In the end, she doesn't even know when she gave her heart to you.
Love, I don’t know where it started, but I love you deeply!
Gu Xu came back to his senses and continued to analyze the problem: "Let's analyze the snail first. It climbed up 9 decimeters on the first day and slid down 7 decimeters at night. So where does it start climbing the next day?"
The little boy replied: "9 minus 7 equals 2. Climb two meters in one day. After climbing for five days, of course it is 10 meters."
The father couldn't help it anymore and yelled: "Are you stupid or deaf? The sister just said 17 meters, and you still said 10 meters."
The more the father talked, the angrier he became and he poked his son on the head hard: "Why did I give birth to such a stupid son like yours?"
The son pouted and stared at his father, wanting to say something but not daring to say more.
Gu Xu said with a smile: "Uncle, don't get excited. This question is deliberately digging a hole. Children can easily fall into misunderstandings. Little brother, look."
Gu Xu drew ten lines with a pencil on the paper and took out an eraser to act as a snail.
“The eraser is the snail, and the snail starts crawling from here.
If you look carefully, if, according to your thinking, this well is only 10 meters. On the first day, I climbed two meters, and on the second day, I climbed nine meters, right to the mouth of the well. "
The little boy scratched his head and looked at Gu Xu. He felt that what Gu Xu said was right, but he also felt that he was right.
Lan Ruosi watched from the side and sighed in her heart that Gu Xu had a good lecture and he was so patient.
In the future, when he teaches his son, he will definitely be a good father!
Um?
Lan Ruosi's face turned red. Why did I suddenly have this idea?
but……
Will I marry Gu Xu in the future?
I……
She shook her head subconsciously, not daring to think about it later!
She came back to her senses and continued to look at Gu Xu.
