Approaching the Chinese New Year, there are people on both sides of the street who are setting up stalls to sell New Year's goods, and there are a lot of them, most of which Cheng Nuo has never seen, and Li Laosan has to help introduce them.

When passing by the stall selling New Year's paintings, Cheng Nuo's face immediately became hot when he heard the shouting, and he remembered the embarrassing scene of buying "paintings" at the beginning, which was really unbearable.

Li Laosan, who was riding a bicycle, noticed this movement, turned around and said, "Sir, do you want to buy 'Wei Trowel'?" Then I'll stop and let you pick carefully. ”

"Don't, are you talking about this New Year's painting, let's get busy with our own business first, and then we'll talk about it later." Although he didn't understand why he was called Wei Trowel, Cheng Nuo didn't want to have anything to do with the painting anymore, and urged him to leave quickly.

As the name suggests, the reason why the New Year's paintings of Beiping City are called "Wei Wipe Zi" is because most of them come from Tianjin Wei Yang Liuqing, and the production technique uses less "drawing" and more "wiping", hence the name.

That is, he is an outsider, and he doesn't know what it means, so he made a joke.

With the pastries they bought, Cheng Nuo and the others walked through the bustling crowd and came to a residential gathering place.

According to the address registered on the list, the first target was found - Shi Jin, who graduated from Columbia University with a master's degree in mechanical engineering.

But what he didn't expect was that the house he lived in was so dilapidated.

Although it is a separate courtyard, you can clearly see that the roof tiles inside are tattered, and it is also overgrown with vasson.

Li Laosan stopped, wiped the sweat from his neck and asked, "Sir, you can't be looking for this house, why don't I look like someone lives there." ”

Cheng Nuo was also full of questions, got out of the car and walked to the door to look at the crack in the door, although the yard was very small, it was very clean, and it should be a permanent residence.

"Not necessarily, maybe the master's family is out." Cheng Nuo retracted his gaze, pulled up the knocker on the door and began to knock: "Is anyone at home, is Senior Shi at home?" ”

But half a day passed, and there was no reply in the yard except for some chickens commotion.

Helpless, Cheng Nuo was ready to get back in the car and go to the next house.

At this moment, a man carrying a small half-bundle of books came over, helped his glasses, and said vigilantly: "Why are you here again?" He also ran to our door and told you, no matter how good the conditions are, I won't go, so I don't have to work in vain! ”

Cheng Nuo and the others looked at each other, and said in their hearts that I haven't said anything yet, why did I refuse, is there some misunderstanding in the middle.

hurriedly explained: "You are Senior Shi Jin, hello, I am Cheng Nuo, a professor in the Department of Mathematics of Peking University, and I need to discuss some things with you." ”

"A professor at Peking University? The Peking University that solved Kroneck's dream of youth? After Shi Jin knew the origin, his attitude was obviously relaxed: "I am Shi Jin, I don't know what you are looking for me?" ”

Cheng Nuo looked around, and there seemed to be someone watching the tricycle, pointing at them and saying, "Senior, look at this ......"

Shi Jin slapped his forehead and said embarrassedly: "I was negligent, come, let's come in and talk." ”

Then he opened the gate and led Cheng Nuo and the others to push the cart in.

As a high-achieving student who graduated from mechanical engineering, Shi Jin immediately paid attention to the tricycle, put the book on it, touched it left and right, and finally pointed to it with interest and said, "Is this your foreign car?" Can I go up and give it a try? ”

Cheng Nuo nodded in agreement, and could see that the other party liked this bicycle very much, and it was exactly what he wanted.

The reason why the first stop of recruiting people is on him is because in the future, light bulb manufacturing or bicycle manufacturing will need the support of mechanical engineering, and Cheng Nuo is just a theoretical school, and it is okay to make a sample, but mass production is beyond his power.

Interest is the best teacher, and at the same time the best working conditions.

Riding the tricycle, Shi Jin walked around the yard a few times before he stopped: "It can be seen that this tricycle should be produced by you, it is very creative, but there is still a lot of room for improvement, such as the chain is too tight, the crankset is estimated to be a little twisted by hand, and the rebound strength ......of the brake component is not enough."

Originally, Li Laosan was still a little dissatisfied with outsiders snatching his tricycle, but now listening to those words that seem to understand or not, he can't help but sigh: It is worthy of being a gentleman, anyone who is looking for can find so many problems, and they must let the dogs study hard.

When Shi Jin finished speaking, he felt a little embarrassed: "I'm sorry, Professor Cheng, I'm also happy to see Hunting, I haven't seen such a novel thing for a long time, and I can't control it all of a sudden." ”

Cheng Nuoxin said that I wish you were like this, which just proves that the other party's sword is not old, and he has not forgotten his knowledge.

To paraphrase a sentence from later generations, he wants to say now: Lao Shi, do you want a machine, as long as you open Chrysostom, I will send it to you later.

However, he was afraid that his attitude would scare the other side, Cheng Nuo smiled: "It's okay Senior Shi, this is also my fool's play, if you are interested, I will make you another one tomorrow." ”

"It costs a lot of money to look at this, so you can't do it." Shi Jin waved his hand again and again, picked up the book again, walked in front and said, "Come, come into the house and talk about something." ”

But the moment he opened the door, Cheng Nuo was stunned, except for a table and two benches, there were large bookshelves on several walls, which were full of books by category, which was very suitable to describe as a sweaty cow.

I took out a professional book at random, and there were notes on the blank pages, which seemed to have been read carefully.

Shi Jin poured a cup of hot water and said politely: "The house is too shabby, there is only white water, do you want to dislike drinking some to drive away the cold." ”

Cheng Nuo took the hot water and put it aside, and asked, "How many books are there here, are they all about mechanical engineering?" ”

"It's not much, it's only about a thousand, most of them are in foreign languages, and mechanical engineering is only a part of it." Talking about his book, Shi Jin also said with regret on his face: "It's a pity that the luggage was lost by foreigners when I returned to China, otherwise there are more professional books." ”

Then the two continued to chat, and when they learned that Cheng Nuo was also a student studying abroad in Geng, and he was also Mr. Tom, who had become very famous recently, Shi Jin's attitude became closer.

Later, Cheng Nuo also learned that after Shi Jin returned to China, because he was not good at communicating, he knew that reading books and touching machines had not been reused, and he was excluded as a marginal figure.

And he was so happy, he bought all the books for more than a dozen yuan a month, except for eating and drinking, eating and sleeping in the stacks of books, and he was almost looking for a partner in the stacks of books.

After hearing the intention, he agreed without saying a word, and was excited to move over immediately.

Cheng Nuo smiled bitterly: "Senior, don't you ask about the salary?" ”

"Money is something outside the body, just give me a bed, eat and buy books." Shi Jin packed up his things and said that the sooner the better: "By the way, junior brother, the house is big enough, there are some foreign books that I translated by myself, and it would be a pity to lose them." ”

Cheng Nuo smiled: "No problem, it's no problem to have another two thousand copies." ”

"That's good, that's good, I'll follow you."

Just when a few people were packing up their things, Cheng Nuo happened to pass by the kitchen after going to the toilet, and glanced at the door open, but he didn't expect Shi Jin to also worship the king of the stove, but this sacrifice is very philosophical when it looks like it.

Three sticks of incense, a bowl of water, and a copy of "Principles of Mathematical Principles of Natural Philosophy".
