After eating breakfast, I waited at home for Uncle Tang San to deliver furniture.

Idle is also idle, take out a piece of wood, think about it, 65 years is the Year of the Snake, then carve a cartoon snake.

It took less than ten minutes for a cartoon snake coiled together to appear in the palm of his hand, and his big eyes flashed as if he could speak. Look at the memories that evoked later generations, the son's first toy was such a cartoon snake, which the son liked very much at that time, and gave it to the girl who was bitten when he was in elementary school.

Looking at it, my eyes were a little moist.

I don't know how long it took, put away the snake carving, took out another piece of wood, and just carved a rough embryo, there was a commotion outside the house.

"Xiao Li, the bookcase is here, you open the door quickly", the voice of the three masters came.

Excitedly opened the door, and saw that Uncle Tang San, Master San, Yan Jiefang and the two young men, they were Uncle Tang San's apprentices, and two long rows of wooden shelves were added halfway last time, and there were two of them working together at that time. Because the workmanship is too simple, the next day I will be transported away on a flatbed truck and put in a secret place where no one is around.

"Uncle Tang San, a few masters, come in", Li Guocheng finally waited for the furniture, hurriedly helped into the house, and ordered it to be put away.

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

"Xiao Li, you have a good idea, use the bookcase as a partition, that is, to maintain the privacy of the bedroom, the living room also looks tasteful, when these bookshelves are full of books, the cultural atmosphere of the whole house will come out, the only pity is that you did not continue to study, as a worker." As soon as the three masters as teachers saw such a placement, they resonated and envied, and clearly pointed out the identity of the worker, and the sour taste was even stronger.

Everyone is a human spirit, and when they hear the voiceover, they all bow their heads to drink tea, or talk to the people around them.

"It's just a blind play, it's not comparable to your three masters, this is a façade", Li Guocheng can't fight back against the three masters because of this little thing.

"You still have to study more, even a worker is a literate worker", the three masters were a little confused.

"Dad, Mom asked you to hurry home after you are done, and let you prepare the paper for the Spring Festival couplets", Yan Jiefang hurried to round the field and looked at this Li Guocheng humbly, Li Guocheng smiled and did not say.

"Then thank you to the three masters and the liberation, remember to call me if you have something to do", Li Guocheng politely arrived.

"We're also leaving", Uncle Tang San was also ready to leave because he got the final payment.

"Thank you", Li Guocheng sent Uncle Tang to the gate of the hospital, and only turned around and entered the hospital after watching him leave.

"Brother Li, you take care of it, my dad doesn't have a bad heart", Yan Jiefang deliberately waited for this Li Guocheng to help his father talk.

Li Guocheng stared at Yan Jiefang a few times, "Jiefang, good boy, it's really okay, I'm back, I have time to drink tea at home."

"Yan Jiefang is so enthusiastic today, he should have something to ask for, or just the next step of idle chess, which is a bit interesting", Li Guocheng secretly thought.

I went home and cleaned up briefly, went out, waited for the bus, and arrived at the library without incident.

I went to the office to show a letter of introduction, paid 1 cent, and applied for a paper reading card. Follow the flow of people into the book area, there is no hurry, just take a good look, similar to the layout of later generations, the biggest difference is that the reading area is larger than the book area, this is just the opposite. What they have in common is the thirst for knowledge and the devotion to learning. Of course, almost all the people in this library show more than thirst, but more piety.

Li Guocheng, infected by everyone, silently took a few books and magazines to the reading area, found a corner, and sat down. Most of them are mechanical.,Found a semiconductor-related.。。

With excitement opened the "juvenile semiconductor radio", the hand-drawn in the book is very exquisite, there was no computer-aided drawing before are hand-drawn by the artist with a ruler, the workload of the drawing of many hands in the book is also very large, the book starts from the diode, the basic knowledge of the transistor begins to explain, and then to the reciprocating single tube machine, two tube machine, three tube four tube machine from shallow to deep illustrated form to the reader.

Since the readers of this book are teenagers, there are no complicated formulas involved in the book, and the basic principles are easy to understand, which is more suitable for teenagers to learn about radio and radio. And there is a detailed circuit connection diagram in the book, as long as you follow the circuit in the book, you can basically assemble your own radio.

After reading it, I was a little disappointed.,Although the writing is really good.,But it's not the content I want.,It's said that there is now a second-generation transistor computer.,But look all over the library.,There's no relevant content.。 It is also understandable that compared to this era, computer-related knowledge is indeed high-tech, and it is estimated that only relevant research institutes have collections.

Remember. Section. Auditor. Calculate. The second-generation transistor computer was developed, but I don't remember exactly when it was developed. But it didn't work, almost all the computer research in later generations changed direction after the change, learning and catching up, and did not see the actual results until the crossing, and the computer architecture was completely monopolized by several major groups.

Mechanical-related aspects are good, they are all translations of Big Brother, which is of great help to their systematics mechanical design.

Li Guocheng was hungry for knowledge, until he was reminded by the administrator that the library was to be closed, and then put back the books, with the flow of people, as soon as he arrived at the door, he saw that people were crowded in one direction, and vaguely heard a girl's shout, "Grandpa, what's wrong with you, don't be quiet." Unleashed his mental power, and saw a white-haired old man with a blue face and a weak breath falling to the ground, looking like a myocardial infarction.

The girl tried to pull up the old man, and several well-wishers also reached out to help, Li Guocheng was startled, and quickly shouted loudly: "Don't move, I'm a doctor." If it is a myocardial infarction, it is best not to move it at will, and you need emergency treatment on the spot, otherwise you will be delayed for 6 minutes, and the person will be gone.

When the big guy heard the voice, he automatically got out of the way, Li Guocheng hurriedly stepped forward, "Everyone please back away, the old man needs circulating air", and then unbuttoned the upper two buttons of the old man's shirt, flattened the old man, and used standard first aid actions to press the chest 30 times, and then artificial respiration twice, and did 3 sets of reciprocating, and the old man slowly woke up.

Li Guocheng pressed the neck artery with two fingers, felt that the transfer returned to normal, and said to the crying girl next to him, "It's okay for the time being, send it to the hospital as soon as possible".

At this time, the staff in the library pushed a board cart, picked up the old man and left.

Originally, everyone wanted Li Guocheng to follow, especially the girl named Jing'er, but considering that she was a Xibei goods, she quickly made an excuse to slip away.
