The ups and downs of life in the Siheyuan

Before the Spring Festival, rewards were distributed, and the laboratory won the collective second prize with a bonus of 5000 yuan.

The certificate of honor and the silver and gold-rimmed medal were placed in the school's honor exhibition room.

Li Yuan received 100 yuan and 2 pounds of relatively precious pork.

When the money was divided among the pork, the whole laboratory cheered.

When leaving school, Professor Zhang went out of his way to find Li Yuan.

"Xiao Li, you have done a great job this year, and our laboratory is lucky to have you join us.

In the coming year, I have a big move, and you will play an important role.

I hope that our Huaqing University can help the country completely get rid of Western coercion in terms of engines."

Li Yuan also had the same idea, so they hit it off and the two reached a gentleman's agreement.

During the Spring Festival, Li Yuan invited Uncle Song home and took He Yuzhu's family to have New Year's Eve dinner together.

I originally wanted to invite the Sun family to spend time with me, but they declined politely.

He knew they were embarrassed.

He had to forcefully keep half a pound of pork, ten pounds of white flour, one pound of leeks and two fish.

Of course, they had to pull each other off, but in the end they couldn't defeat Li Yuan, so they had to keep their gratitude deep in their hearts.

The Sun family of four happily gathered together to make dumplings.

Aunt Sun's family was weeping silently. Old Sun's head knew that she was happy for this year's prosperity, but also sad for her parents' family.

Last month, my father-in-law was severely malnourished and suffered from edema.

Years ago, my younger brother came to the door asking for help, but unfortunately they had no food left, so they reluctantly sent him away.

Seeing so many good things today, her heart was moved, but she didn't dare to open her mouth and would only cry.

Lao Suntou thought for a while, got up, divided out half of the white noodles and half of the dumpling fillings, and was about to go out with two fishes.

His actions startled Aunt Sun.

When she learned that these were given to her parents' family, she covered her mouth and cried.

Two sensible children gathered around their mother and comforted her softly.

There is a saying that for every man who slaughters dogs for justice, he will be a scholar for every heartless person.

The west wing of the south courtyard is also very lively. This year, there is a new addition to the family.

Yan Jiecheng got married at the end of the year, and his wife's name was Yu Li, a shrewd and sensible master.

There are three people in the Yan family working, and the two sons’ work is also profitable. At the end of the year, they buy some meat.

The two brothers also got a pair of sheep and half a pound of pork, which was considered a rare fat year.

Plus Yan Fugui’s experience as a fisherman in one winter.

It has been a very prosperous year for my family.

The days are getting easier, and Yan Laoji is not like he used to be, but he keeps most of the meat.

It's a pity that Yan Fugui and his wife, who are used to hard times, count the dumplings to share with everyone, making this year not so wonderful.

The west wing of the backyard was deserted. It was obvious that Xu Damao's family did not celebrate the New Year in the courtyard.

In the Liu family's east wing, Liu Guangfu knelt in the corner and cried silently.

Just because he said something, he was beaten, he didn't eat, he didn't say anything, and he had to kneel down to think about his mistakes.

Liu Guangtian, who was doing well at work, sat at the table with his parents, drinking wine and eating vegetables. He seemed to have forgotten that there was a younger brother in the corner.

Liu Guangfu looked at this side with resentment in his heart, "Didn't I just ask: Brother, will you go home to celebrate the New Year this year?"

The west wing of the middle courtyard, Jia's family.

It is also quite lively here. Yi Zhonghai’s family, the deaf old lady and the Jia family celebrate the New Year together.

The family gathered together and were making dumplings.

It's just that the old lady's occasional appearance of a long pillar or a short pillar makes Jia Dongxu not very happy.

In the east wing of the front yard, the sound of drinking orders has already sounded:

six six six

five chiefs

Eight horses

Nine Links

. . . . . .

Liu Yuan held Xiao Hua and Tian Xiujuan held Qi Jin, smiling as they watched He Yuzhu and Uncle Song perform the drinking orders.

Uncle Song was very happy today and gave Qijin 1 yuan very generously.

He Yuzhu tried his best to prepare a table of delicious dishes.

Pulling Uncle Song, I want to get drunk and never come back.

They didn't pay much attention to Li Yuan, because no matter how hard they tried, they were the ones who got drunk every time.

Li Yuan was left in peace, occasionally raising a glass of wine to toast to the loser.

When I was tipsy, I blurted out a Mongolian song:

"...

Ulaanbaatar by night

So beautiful, so beautiful

. . .

The singer often sheds tears

. . . "

Then there is a long Mongolian tune.

The long tune spreads to the front yard, middle yard, and back yard, and then goes straight up to nine days.

When school started after the holiday, Li Yuan heard bad news.

On the second day of the Lunar New Year, Professor Zhang Ran was hit by a truck on his way to greet the new year.

Fortunately, Professor Zhang was lucky and could hide quickly. Although his leg was only broken by the crush, his head was hit on the curb.

He has not yet regained consciousness and is currently being treated at No. 301 Hospital.

On the same day, the police found the hit-and-run truck, but the driver was stabbed to death on the side of the road.

The driver is a gangster, and the only person at home is his seriously ill grandma.

The truck was a lost vehicle from a factory.

The matter was settled, but another party took over the entire case.

The real culprit is being traced.

Today Li Yuangang entered the laboratory and was informed that the research was suspended. The specific time will be determined after Professor Zhang recovers.

At the same time, Li Yuan also discovered that there were two more capable young people in the laboratory.

Li Yuan, who had nothing to do, applied and began to audit computer science courses.

In early 1956, Tsinghua University decided to add a computer major, and immediately transferred third-year students from other majors to this major, with plans to train the first batch of graduates in 1959. This is the earliest computer major established in New China.

The current teaching is not very mature yet. It should be explored, taught and practiced at the same time.

The Department of Computer Science is currently developing the 911 machine.

This is a medium-sized general-purpose electronic digital computer designed and manufactured by Tsinghua University.

Started in 59, the main structure is now being built.

Since 1960, the domestic economic situation has taken a turn for the worse, and most of the scientific research projects in the school have been cancelled. However, the 911 aircraft is one of the few retained projects.

Li Yuan was fortunate to witness history, but unfortunately he was only an auditor and could not participate. He was allowed to attend lectures and visit because of the leadership's instructions.

The 911 machine uses small tube circuits and magnetic core storage. Word length 31 bits, instruction format: fixed point/single address.

The 911 machine laid a solid foundation for the success of a series of future research projects.

In Li Yuan's eyes, the 911 machine is crude. It is said to be a computer, but it is more like a big toy.

It is its main structure, covering an area of ​​almost hundreds of square meters.

Since we only have Big Brother's drawings, we can say that we are moving forward with enthusiasm and persistence.

Li Yuan scanned all the drawings into his mind and began to build the 911 model in his mind.

This process of building a computer from the bottom was an eye-opener for Li Yuan.

Compared to later generations, these may seem childish and ridiculous.

But precisely because it is the lowest and most primitive design, Li Yuan started learning from the essence of computers.

From this day on, the little auditor in the Department of Computer Science slowly came into everyone’s sight.

From rejection at first, to acceptance step by step.

On this day, Li Yuancong came to a teacher again.

"Teacher Ni, are you busy?"

"It's Xiao Li. You can go play somewhere else. I'm busy here and can't take care of it."

"Are you busy? What do you think I can do to help you?"

Li Yuan started his secret learning journey again today.
