Siheyuan: Starting from a fitter

Chapter 20 Libraries

After breakfast, we waited at home for Uncle Tang to deliver furniture.

I was free, so I took out a piece of wood and thought for a while. 65 is the Year of the Snake, so let’s carve a cartoon snake.

Just do it, saw sawdust flying, and in less than 10 minutes, a coiled cartoon snake appeared in the palm of your hand, with big eyes blinking, as if it could talk.After watching it for a while, it brought back memories for later generations. My son’s first toy was such a cartoon snake. At that time, my son liked it very much and gave it to the girl who was bitten when he was in elementary school.

Looking at it, my eyes felt a little moist.

I don’t know how long after I came here, I put away the snake sculpture, took out another piece of wood, and just carved a rough embryo when there was a noise outside the house.

"Xiao Li, the bookcase has been delivered. Please open the door quickly." came the third uncle's voice.

Opening the door excitedly, I saw Tang Sanshu, Third Uncle, Yan Jiefang and two young men. They were Tang Sanshu's apprentices. Two long rows of wooden shelves were added halfway last time. At that time, they were the two of them working together.Because the workmanship was too simple, I used a flatbed truck to transport it the next day and put it into the secret place where no one was.

"Uncle Tang, gentlemen, come in quickly." Li Guocheng finally waited for the furniture and quickly helped to carry it into the house and ordered it to be put away.

Li Guocheng hurriedly gave up his seat to everyone and handed over the toast.

"Xiao Li, your idea is good. Using the bookcase as a partition keeps the privacy of the bedroom, and the living room also looks tasteful. When these bookshelves are full of books, the cultural atmosphere of the whole room comes out. The only pity What's more, you didn't continue studying and became a worker."As a teacher, the third master felt sympathy and envy when he saw this arrangement. He subconsciously pointed out his identity as a worker, and everyone around him could feel the sour smell.

They are all human beings who heard the voice-overs, drinking tea with their heads down, or chatting with the people around them.

"It's just a joke. I can't compare with your third uncle. It's just a facade." It was impossible for Li Guocheng to fight back against the third uncle because of this trivial matter.

"You still need to study more. Even a worker is a well-educated worker." The third uncle was a bit at a loss of whether to advance or retreat.

"Dad, Mom asked you to go home as soon as you finish your work. It's time to prepare the Spring Festival couplets." Yan Jiefang hurriedly smoothed things over and looked at Li Guocheng humbly. Li Guocheng smiled and said nothing.The third uncle also reacted, his expression was a little dazed.

"Thank you, Mr. Third, and Jiefang. Remember to call me tomorrow if you need anything," Li Guocheng said politely.

"We're leaving too." Uncle Tang San got the balance and was ready to leave.

"Thank you all," Li Guocheng sent Tang Sanshu to the gate of the courtyard all the way, and then turned back to enter the courtyard after watching him leave.

"Brother Li, please be patient, my dad is not evil-minded." Yan Jiefang deliberately waited for Li Guocheng to help his father's words.

Li Guocheng stared at Yan Jiefang for a few times and said, "Jiefang, good boy, everything is fine. I'm back. I'll have tea at home when I have time."

"Yan Jiefang is so enthusiastic today, it should be something he wanted, or he could make a move ahead of time, which is a bit interesting. The calculations of the old Yan family have become the inheritance of supernatural powers, which is engraved in his bones," Li Guocheng thought secretly.

I went home and tidied up briefly, went out, waited for the bus, and arrived at the library smoothly.

Go to the office to show your letter of introduction, pay the 1 cent fee, and apply for a paper reading card.I followed the flow of people into the book area and was not in a hurry. I just had a good look at it. It was similar to the layout of later generations. The biggest difference is that the reading area is larger than the book area, which is exactly the opposite.What they have in common is the reader's thirst for knowledge and their investment in learning.Of course, almost everyone in this library showed not only desire, but also piety.

Li Guocheng, influenced by everyone, silently took a few books and magazines to the reading area, found a corner, and sat down.Most of them are related to machinery, and I found a book related to semiconductors.

I opened "Youth Semiconductor Radio" with excitement. The hand-drawings in the book are very exquisite. Before there were no computer-aided drawings, all the drawings were done by artists with rulers. The workload of the many-hand drawings in the book was also very heavy.The book starts from explaining the basic knowledge of diodes and triodes, and then presents it to the readers in the form of pictures and texts from the shallower to the deeper.

Since the readers of this book are all teenagers, there are no complicated formulas involved in the book, but simple and easy-to-understand basic principles, which is more suitable for teenagers to learn radio knowledge.The book also contains detailed circuit connection diagrams. As long as you follow the circuits in the book, you can basically assemble your own radio.

After reading it, I was a little disappointed. Although the writing was indeed good, it was not what I wanted.It is said that there is already a second generation transistor computer, but after searching the entire library, there is no relevant content.After thinking about it, I understand that computer-related knowledge is indeed high-tech compared to this era, but it should be relatively precious. It is estimated that only relevant research institutes have collections.

I remember that the Institute of Computing Technology of the Chinese Academy of Sciences also developed the second-generation transistor computer in the early days. I can’t remember exactly when it was developed.It's a pity to think about it. The second-generation computers developed by the Institute of Computing seem to have made a lot of contributions to national defense construction, as well as the Galaxy mainframe computer. After the reform, almost all computer research in later generations changed directions, learning and catching up. Before time travel, No actual results have been seen, and the computer architecture is completely monopolized by a few major groups.

I remember that later generations participated in the research and development of the Sugon 3000 large computer. The basic unit is IBM's 4-core (4 independent CPU) computers, which are called nodes. All nodes are connected to a server using network cables. The core technology of Sugon is parallel computing and synthesis. Scheduling.The operating system is free and open source Linux, which is the three most important projects in the 863 plan at that time.

The mechanical related aspects are quite good. They are all translated by Big Brother, which is of great help to me in systematically learning mechanical design.

Li Guocheng absorbed the knowledge eagerly. He didn't put back the books until he was reminded by the administrator that the library was closing. As people flowed out, as soon as he arrived at the door, he saw people crowding in one direction, and vaguely heard a girl shouting, " Grandpa, what’s wrong with you, don’t scare Jing’er.”I released my mind power and saw an old man with white hair, his face was blue and purple, and he fell to the ground with weak breath. It looked like his symptoms were myocardial infarction.

The girl tried to pull the old man up, and several well-meaning people also reached out to help him. Li Guocheng was startled, and quickly stopped: "Don't move, I'm a doctor."If it is a myocardial infarction, it is best not to move it at will. Emergency treatment is required on site, otherwise the golden 6 minutes will be wasted and the person will be dead.

When the big guy heard the sound, he automatically moved out of the way. Li Guocheng hurriedly stepped forward and said, "Everyone, please step aside. The old man needs some air circulation." Then he unbuttoned the two upper buttons of the old man's jacket, laid the old man flat, and used The standard first aid action was to compress the chest 30 times, and then perform artificial respiration twice for 3 sets. The old man slowly regained consciousness.

Li Guocheng pressed the carotid artery with two fingers. When he felt that the beating returned to normal, he said to the crying girl next to him, "It's okay for the time being. Send him to the hospital as soon as possible." At this time, he must be straightforward and use a positive tone to induce the patient's family members to follow the doctor's instructions. Don't explain too much to avoid getting entangled and wasting precious time.

At this time, the staff in the library pushed a cart, carried the old man on it and left.

Originally, everyone hoped that Li Guocheng would follow, especially the girl named Jing'er, who bowed repeatedly, but considering that he was a Xibei, they quickly made an excuse and ran away.

　I insisted on writing a chapter and only checked it once. I really couldn’t hold on anymore. I will check it again tomorrow.If there are any errors, please remind me in time and I will correct them as soon as possible.
