Bai Hao looked at the little girl reaching out to him and asked in confusion:
"Want, what do you want?"
"I, you, I want to buy you two packs of Leisha Yuan, and I'll give you an extra ten cents, eighty cents." After the little girl finished speaking, she realized that the money was gone. She searched around for a while, but couldn't find it.
It must have been lost when I was following Bai Hao just now.
Bai Hao didn't think too much. He had just bought everything, and he had a long string of hemp rope paper bags in his hand.
He untied the hemp rope and took out two packages. Each package cost 35 cents. Bai Hao didn't intend to ask for money, so he stretched out his hand and handed it over.
The little girl was very grateful, bowed fiercely and ran away.
This matter is finally over.
Bai Hao continued walking to the Bund, he wanted to see the river.
But after walking a few steps, the little girl appeared again and pulled Bai Hao's clothes.
"Can you lend me two cents? I want to go back by car."
"Yeah, okay."
Bai Hao started to touch his body, the smallest denomination was one piece.
This is a big bill.
One dollar is enough for a day's meals without a big meal.
"Here you go, you don't have to pay it back." Bai Hao handed the money to the little girl, who shook her head: "Tell me who you are, leave me an address, and I'll send the money to you when I get home."
"Forget it, no need to pay it back."
"Then I don't want it anymore. I'll walk back." The little girl turned around and left.
Two cents for the ticket.
Bai Hao knew that the fares on the Shanghai Stock Exchange were five cents, one dime, one dime and five cents, two cents, and two dimes and five cents.
How many stops does it take for two cents? Even if you transfer, it will be at least a dozen stops. Walking back is like walking until your legs break.
Okay, write the address.
Bai Hao clearly wrote on the little girl's homework book, the words "Bai Hao of the Ninth Branch of Qinzhou Jingzhao Industrial and Electrical Engineering", followed by the zip code and so on.
The little girl also wrote her name.
Chu Junlan.
Then he accepted Bai Hao's dollar, turned around happily and ran to the bus stop over there.
But who would have thought that if he was not careful, he would fall to the ground.
One dollar was blown up by the wind and fell into the river, and two bags of sand balls were directly run over by passing bicycles.
Bai Hao was stunned for a moment, then burst out laughing.
This unfortunate girl.
Chu Junlan gritted her teeth and got up from the ground. Fortunately, it was cold now. The skin on her palms was only scratched a little and the sleeves of her clothes were torn, but the rest was not injured.
When Chu Junlan looked back, Bai Hao was a little embarrassed and hurried over to help her up.
"You live there, I'll take you back. You look like this, which makes people very worried." Bai Hao was a little worried about the little girl in front of him, and felt a little confused.
Chu Junlan pouted and looked at the crushed Lei Sha Yuan on the ground, feeling so uncomfortable that she wanted to cry.
I ran all this way because of this.
But it’s gone.
Bai Hao squatted on the roadside and looked at the crushed paper bag, and suddenly asked: "You seem to have studied the delicious food in Shanghai. From the accent, you don't seem to be from Shanghai."
Chu Junlan stood up on her own, without letting Bai Hao help her, and patted the soil: "My dad was transferred to Mingzhou Port to work, and I temporarily stayed at my aunt's house for a few days during the weekend. When it comes to the delicious food in Shanghai, I
But the clearest."
"Let's go, if there's anything delicious, take me there."
"Well, if you want to eat well, you'd better eat full."
"Eat well, I'll treat you, and you will lead the way."
Chu Junlan looked Bai Hao up and down for a while, then nodded slightly: "It doesn't look like you are a bad person, okay. The first stop is to eat crab shell roe, four stops away from here."
"Walk."
Bai Hao planned to have something to eat and send the little girl home. After all, it was getting dark.
But soon, Bai Hao discovered that Chu Junlan was a real foodie.
She can actually find the humble scallion pancakes, steamed dumplings, and fried dumplings in a remote alley. And the taste is extremely authentic.
We became familiar with each other while chatting.
While waiting for the onion noodles, Chu Junlan said to Bai Hao: "I came to Shanghai to buy some materials to repair my model. I signed up for this year's National Youth Invention and Creation Competition and Science Symposium. This year's theme is the sky.
"
"Oh." Bai Hao didn't remember this because he had never participated.
However, Bai Hao had heard Lu Ming's elementary school and Yang Liu's high school mention this, and he also knew that this year's theme was the sky and all forms of registration were accepted.
Chu Junlan took out a picture as if to show off a treasure: "This is my model."
When Bai Hao saw it, he immediately smiled and said, "It's amazing, it's great."
"Lie to me, and you won't look down on me." Chu Junlan stared at Bai Hao's eyes when Bai Hao looked at the picture she drew. She believed in her intuition.
Bai Hao waved his hand: "Really, I won't lie to you. As a person...how old are you?"
"I'm a freshman in high school."
"Yes, yes, as a high school student, this is great."
"You lied to me. I don't want to eat. I want to go back." Chu Junlan was a little angry. Her family was perfunctory with her and she didn't have time to watch. Now this seemingly good guy was also perfunctory with herself.
Bai Hao quickly said: "No, if I tell the truth, you might cry."
"Don't be afraid, I want to hear the truth."
Bai Hao took out a pen from his pocket and drew directly on the picture: "You are just lying to children. The shape of this wing can fly, but it will affect the power of your model. From an aerodynamic point of view, this kind of wing
The tip of the aircraft will vibrate in the air, and the faster it flies, the greater the vibration. Of course, the model cannot see it. But the motor is so powerful, and a good wing structure will allow the model to fly higher, faster, and more flexibly."
"Look, let me calculate it for you."
Bai Hao has been studying this recently, because Catherine wants to build an airplane, and they are all top academics... Jeff Haas is not counted. So a lot of data needs to be calculated.
As soon as the stream function and bit function came out, Chu Junlan was stunned.
She couldn't understand.
But she clearly saw that Bai Hao directly changed the thickness, fold angle, and wing angle of the wing. He also designed a sharp tip for the wing to balance the air turbulence.
What is air turbulence.
Chu Junlan didn't understand it at all, but she saw the exquisite chart with detailed data casually drawn on the paper.
She knew that she had met an expert.
Bai Hao continued to change: "Double channel is too common. Four channel. I have the materials where I live. I will make a controller for you later. Four channel is a good model."
"Well, I don't understand these functions."
"If you don't understand, it doesn't matter. You just need to understand a few formulas. The model is not that complicated. I will send you some learning materials later. This thing is very simple."
"Yeah, yeah." Chu Junlan nodded fiercely.
In addition to putting away the drawings, Chu Junlan also asked Bai Hao to write the names of several books, and she planned to go to the bookstore to buy them back.
At about ten o'clock in the evening, Bai Hao sent Chu Junlan to the door of where she lived, and then called the hotel car to pick him up.
Back at the hotel, Bai Hui asked: "It's been so long to get something to eat."
"No, I met a little girl." Bai Hao was right. He told the whole story in detail, and finally asked: "What about the invention and creation competition? What about meeting? If you get the ranking, you will get extra points for the college entrance examination."
