Engineering drawing I rule you

Tokyo University Earthquake Research Institute, conference hall.

Qin Yiyan was dressed in formal attire, stood in front of the electronic screen and talked with the audience in standard English.

"Because the construction of prestressed tendons is more complicated, the effect of swinging walls in actual application is not ideal. In view of this, we try to make improvements in materials and structures, by adjusting the ratio of reinforced concrete, link materials and spatial structure of dampers , play the role of strengthening the lateral force resistance and reducing the plastic deformation of beam-column joints..."

As a kind of shear wall, swing wall plays an important role in fighting against natural disasters.At present, the theory of this technology has basically taken shape, but how to put it into practice is still a problem that plagues the engineering community.Qin Yiyan has been engaged in the research of geotechnical and new materials since his Ph.D., hoping to make breakthroughs in the fields of physics and chemistry.

Japanese scholars were very interested in their ideas. After listening to Qin Yiyan's brief introduction, they discussed the feasibility of the plan from the perspective of earthquake propagation characteristics and uncertainties, and put forward many useful suggestions.

When the meeting was over, they still shook hands with Qin Yiyan and bowed, praising him as a new force in scientific research, who will surely make great contributions to the field of architecture.

Qin Yiyan just smiled to express his gratitude.

With the end of this seminar, the group's trip to Tokyo has also come to an end.The instructor allowed them to go shopping in the city center in the afternoon, then go back to the hotel early to rest, and prepare to go to Miyagi and Fukushima tomorrow morning.

Junior sister Zhou Rui immediately walked between the two excitedly, suggesting to go to Ginza or Akihabara to play.Qin Yiyan didn't like crowded places, so she politely declined her invitation.

Zhou Rui felt that it was a pity, and continued to persuade: "But since you have come to Japan, you should experience the customs and customs of different countries. Akihabara is a famous scenic spot in Tokyo. There are many comics and figures. There must be characters you have heard of. .”

"Manufactured?" Qin Yiyan focused on this word.

"That's right!" Zhou Rui approached him with a smile, "It seems that you don't understand at all."

He was noncommittal, thinking of Xie Huai and Rukawa Feng he had mentioned, nodded and said, "Let's go and have a look together."

The three of them took the subway and got off at Akihabara Station about an hour later.Zhou Rui seems to understand the Two-dimensional culture very well, holding a mobile phone to navigate, walking in front of the two to guide the way.Qin Yiyan was not in a hurry to buy things, so he wandered behind her, observing the buildings on both sides.

However, according to Zhou Rui's personality, it didn't take long to bring them to the animation zone, and saw many beautiful and handsome cosplayers, who called them "Kawaii Ina".

Qin Yiyan looked at the bustling and jubilant atmosphere on the street, but felt that it was too noisy, so she walked silently and listened to her popular science.

Suddenly, a row of packaging boxes printed with red basketball uniform characters on the shelf came into view, he couldn't help but stop, and opened the search software.Seeing that he didn't keep up, Zhou Rui turned back curiously: "You also like slam dunks?"

He didn't answer the call, and picked up a box to check, and found that it was a series of blind box figures, and there was no guarantee that the style Xie Huai wanted would be sold.But after weighing it in his hands for a moment, he still put the things in the shopping cart.

"I knew you must have seen this classic work. I finally don't have to rack my brains about what to give you during the next festival." Junior sister Zhou Rui was very satisfied with this discovery.

Seeing her excited look, Qin Yiyan said blankly, "Don't get me wrong, this is for my cat."

She frowned: "Is that the injured cat you mentioned last time?"

"Yes, I kept him in the rescue station."

"Then you don't need to sell a figure to use it as a toy, right? It's too extravagant!" The brother interrupted him, pointing to the clearly marked price of 1 yen, dumbfounded, "a figure worth more than 6 yuan will be sold in a few days." Don't you feel sorry for being bitten by a cat?"

But he shrugged nonchalantly, and walked to the cashier to pay with a look of willingness.Zhou Rui grabbed the senior brother and whispered in his ear: "Don't be surprised, maybe he found a girlfriend and was too embarrassed to say it, so he just replaced it with 'cat'."

"That's too interesting." The senior brother was puzzled, "I can't tell that he is such a person at ordinary times."

Qin Yiyan walked to the cash register, and was attracted by a pair of gray-pink cat ears. Remembering Xie Huai's reluctance to pick and pull the cat food bowl on the hospital bed, he couldn't help taking it off the shelf.

Japan is worthy of being the birthplace of cute culture. Every detail is designed just right. When you pinch the cat's ears, it even makes a "meow" sound.

Seeing this, Zhou Rui stepped forward and asked curiously: "Brother, is your cat cute? When will you bring it for us to see?"

"It's not cute, it's timid and likes to scratch people, so it's not convenient to show it to you." He described it almost without thinking, paused for a moment and added the second half of the sentence, "He only obeys me."

The tone inexplicably carried the meaning of swearing sovereignty.

Zhou Rui suddenly realized and nodded, flirting with his senior brother.

Ten days passed in a flash, and Xie Huai was also busy preparing gifts for him.In any case, finding time to help me make up lessons is far beyond the scope of the job of a university teaching assistant. Although Xie Huai is annoyed by his mouth, he still knows how to repay his kindness in his heart.

In order to prevent stepping on the thunder, he specially asked for Tan Qi's WeChat from Zhu Kecheng, and planned to start with his colleagues.It's a pity that Qin Yiyan doesn't seem to have a deep friendship with anyone else. Tan Qi doesn't know what he likes at all, and only occasionally discusses the relationship between programs and data processing.

However, Tan Qi promised to notify Qin Yiyan as soon as he came back, and also helped him out by saying: University teaching assistants are also considered teachers, if you really want to thank you, you can definitely send a pennant.

These words gave Xie Huai great inspiration.But he also felt that the popular blessings on the market were too clichéd. He wanted to surprise Qin Yiyan, racked his brains for a long time, and bought a new screen by the way, planning to help him remodel his office.

All is ready except for the opportunity.

After dinner on Thursday, Tan Qi, who had been silent for a long time, sent him a message, saying that Qin Yiyan had returned to China, and now he was approving homework in front of him, and asked him to come over as soon as possible.After receiving the news, Xie Huai couldn't wait to pack up his things and set off.

In the morning, I heard that the first snow fell in Jingzhou today. Unexpectedly, after staying in the dormitory for a whole day, ten centimeters of snow had already accumulated on the ground.The snowflakes fluttered densely in the night, and there seemed to be no tendency to stop.

Xie Huai, as a true native of the water town, loves and hates snowy weather. He can't help the urge to have a snowball fight with his friends, but he thinks the ground is difficult to walk and easy to fall when it freezes.

At this moment, he was pushing the screen given to Qin Yiyan, walking with difficulty on the ground compacted by everyone's footsteps.Because he was worried that Qin Yiyan would go crazy again and break things, he specially chose an exquisite plain screen this time.

The lights were on in the office, he opened the door politely, and sure enough, he saw a familiar figure in the deepest part of the office.

"Senior Qin, good evening." He greeted probingly.

Qin Yiyan looked up at the door when he heard his voice: "Hand in your homework?"

"That's right, by the way, I'd like to say hello to you." Xie Huai lay at the door, only leaning out his upper body, and said with a playful smile, "Thank you Senior Qin for helping me make up the lessons. I got 83 points in the engineering drawing test this time!"

He frowned slightly when he heard the words, and was just about to answer, but was interrupted by a melodious suona playing.I saw Xie Huai pushing a screen covered with red cloth, with an Ansai waist drum on his waist, following the sound of suona coming from somewhere, walking towards him with catwalks and ecstasy.

The rhythm of the music was fast and lively, like a folk song played during a wedding in the village. He twisted his buttocks vigorously to the beat of the music, playing the momentum of the entire drum team by himself, and almost brought the Loess Plateau to his eyes.

All the teachers in the office stopped their work and cast curious eyes on this well-known problem student in the whole school.Seeing this, Qin Yiyan stood up and stopped him: "Xie Huai, are you still making trouble in my office?"

"Don't get me wrong! I'm here to thank you from the bottom of my heart." He quickly tore off the red cloth, revealing the picture of a bobcat and chrysanthemum with delicate brushstrokes on the screen, pointing to the striking yellow chrysanthemum in the center of the picture, and solemnly explained, "Chrysanthemum, and Mei Lan belongs to the Four Gentlemen of Flowers. As an apology for breaking the screen last time, it should be considered an equivalent exchange."

After speaking, Xie Huai shook the red cloth in his hand again, showing the big golden characters on the front, and walked up to Qin Yiyan by beating gongs and drums through the unfinished BGM: "General—this is what I customized for you. pennant."

I saw it said: Gongtu is not easy to meet the king, but rare; the middle way knows how to face difficulties.

Although he usually looks ignorant, he is still very reliable when doing business seriously.I just don’t know why, but this couplet exudes a philosophical atmosphere all over the body, even if it is to thank the teacher for his words, and the chrysanthemum screen is even more imaginative.

Sure enough, the teachers next to him laughed softly.Even Tan Qi, who knew the before and after of things, covered his mouth with difficulty and suppressed his smile, stepped forward and patted Qin Yiyan on the shoulder and said, "Xiao Xie is really hardworking, and I even gave you an original couplet. You see, Zhu Kecheng, who I taught, doesn't have this Mind."

"Also, the students send the pennant to the teacher to take pictures as a souvenir." He pushed Xie Huai towards Qin Yiyan maliciously, took out his phone and took a few steps back.

"That's right, Mr. Qin, just accept this kindness." The other teaching assistants also booed, "This is an affirmation of your teaching level!"

"I..." Amidst the din of the crowd, Qin Yiyan was speechless, and looked at the camera with an old dog's face.Xie Huai smiled happily, and contentedly went up to stick with him, leaving this precious group photo.

He didn't want to stand still for a second, waited for Tan Qi to press the shutter, walked back to the desk and said, "The mid-term paper is not difficult at all, isn't it a matter of course to get a high score?"

Xie Huai moved the screen to the previous position, and looked at him from behind: "Not everyone can get high marks in the exam. And you know, Yang Wenwei praised me face to face, and scolded Jiang She for not being as solid as I am. At that time His face is as angry as a pig's liver!"

"Don't be complacent with a little achievement." He still refused to let go.

Xie Huai resentfully put away the borrowed Ansai waist drum, put his homework on the table, and said, "Actually, there is one more thing I want to tell you. Tibetan songs, Teacher Zheng asked if you could come and help."

"Sure enough, she still went to look for you." Qin Yiyan said without raising his head as he read his homework.

"Since you can speak Tibetan, isn't it easy?"

But he didn't seem to want to mention this matter in front of his colleagues, so he got up and patted Xie Huai on the shoulder: "Go out and talk."

The wind and snow outside the window were still falling, Xie Huai looked at the foggy night and suggested, "Then let's go for a walk in the snow, today is the first snow."

"Childish." Qin Yiyan couldn't help complaining, but still took out a pair of gloves from the drawer and put them in his pocket, and followed him out of the house.

Without indoor heating, winter in the north is simply not a place for people to stay.Xie Huai was moving the screen up to the fifth floor by himself just now, when he suddenly felt a little pain in his wrist, he kept bowing his head and breathing heavily.

When alone, Qin Yiyan's attitude seemed to be less indifferent than before. From the corner of his eye, he caught his shivering appearance, took out his gloves and handed them over: "I don't know how to keep warm if I'm injured."

"Aren't you wearing it too?"

"I'm not afraid of the cold." He said lightly, "Can people who grew up on the plateau be like you?"

Xie Huai coughed a few times in embarrassment, took the gloves obediently and put them on.Qin Yiyan didn't stop to wait for him. Seeing that he fell a certain distance, he hurried to catch up.

But the frozen snow was too slippery. He didn't pay attention to the road conditions under his feet. He stepped on the ice and flew forward, screaming like a pig.Fortunately, Qin Yiyan didn't go far, turned around and grabbed his elbow, Xie Huai immediately found a savior, hugged his arm, and still cursed angrily, like a cat whose butt was scorched by fire.

For some reason, this feeling of being embarrassed and having to rely on herself gave Qin Yiyan a moment of pleasure.He took Xie Huai to a place where the snow hadn't been shoveled, and suddenly asked, "Do you know how we have snowball fights over there?"

"how to spell?"

"Bury you." As soon as he finished speaking, his hand was already aimed at Xie Huai's shoulder.Unprepared, he fell backwards and fell hard into the snowdrift, creating a manhole.

Before he had time to catch his breath, Qin Yiyan squatted on the ground, pulled off his down jacket, and threw a snowball into it.

"Ah—" Xie Huai shrank his neck in the cold and let out a miserable cry.

"Shhh." Qin Yiyan put his index finger against his lips, carefully observed the surrounding situation, and slowly pushed his collar aside to grab his neck, "Don't you think it's suitable to commit crimes in this kind of blizzard?"

His hands have been frozen cold for a long time, but he seems to be immersed in the joy of killing, and he can't feel a trace of cold at all.Xie Huai was held down in the snow by him, swallowing hard.

The Adam's apple rose and fell with breathing, giving Qin Yiyan a signal that he was nervous.

"Didn't you take your medicine?" Xie Huai asked hesitantly for a long while.

"Huh? But benzodiazepines seem to be unable to control my condition." Qin Yiyan frowned in embarrassment, bit his earlobe and whispered, "Now I need a new drug to relieve negative emotions."

"..." Heat waves and chills lingered in his ears, and Qin Yiyan slowly stroked his Adam's apple, like playing with a lifeless walnut.

Xie Huai quickly calmed down, sat in the snow and let him caress.The two stood in a stalemate for a while, and he finally took a breath, and asked, "Oh? Then you're just trying to kill me now."

He didn't get nervous and hyperventilated when he encountered everything. Seeing this, Qin Yiyan closed his hands boredly, and squatted on the ground with a smile: "Yes, you really understand me more and more."

After finishing speaking, he took out another small box from his pocket and threw it on Xie Huai: "Let's take this as an apology for that day."

"What?" The surrounding light was dim, he didn't see the packaging clearly, he thought Qin Yiyan had thrown a bomb over him, and jumped up and down in fright.

"It's your favorite basketball figure." Qin Yiyan took a few steps back to look at him, "It's just a blind box, I don't know what's inside."

Xie Huai let out a long sigh of relief, picked up the baby figure and quickly disassembled it, carefully inspecting it against the street lamp.

"Wow, it's really Rukawa Kaede!" Seeing the familiar figure, he excitedly took off his gloves, touched the clay full of memories in his hands, and asked him, "How much?"

"As long as you like it." Qin Yiyan just nodded lightly, "I'll see you off."

Anyway, it was bought with a scholarship.Qin Yiyan thought, with the National Award plus the Huagou Group's bursary, a total of 6 yuan is more than enough to raise a cat.

The author says:

Sorry, there are a lot of classes after school, and then I accidentally wrote too much orz
