"Hahaha. Duan Yun smiled when he heard this, and said, "Actually, I just remembered it in the afternoon. ”

"You liar, you obviously just want me to ......" Cheng Qingyan raised her eyebrows, then pursed her lips and said with a smile: "Forget it, for the sake of you giving me the book, I won't care about you." ”

"Huh. Duan Yun smiled and asked Cheng Qingyan, "Is it what you want to see these books?"

"Hmm. Cheng Qingyan nodded when she heard this, and said: "I also have this "Dictionary of Mechanical Engineering" at home, but my father bought it a long time ago, it has been more than ten years, and many things are outdated, I didn't expect you to be able to buy a new version, look at the thickness, you know that it is much better than my one......

"If you like it, if you like. Duan Yun pointed to the "Mechanical Engineering Automation" and "American Engineer's Handbook" on the desktop with his hand, and said: "These two books are actually very good books, I took a look, and many of them are currently more advanced design cases in the world, which will be very helpful to you." ”

"How do you know so much, have you read these books?" Cheng Qingyan said in surprise.

"There was an English version in the bookstore, and after we had negotiated, I spent most of my time wandering around the bookstore in Berlin, looking through several books, and if the boxes didn't fit anymore, I could have brought back some more. Duan Yun said.

"Your vision is really good...... Cheng Qingyan looked through the table of contents of the other two books, then turned her head and said to Duan Yun gratefully: "These three are very useful books, I really like them." ”

"You read these books first, I am already a translator of the city bureau now, and if there is a chance to go abroad in the future, I will bring you books. Duan Yun said with a smile.

"Really!?" Cheng Qingyan's eyes lit up when she heard this, and she asked excitedly.

"It's just a gesture, anyway, I definitely have to buy things when I go abroad, if you need me to bring anything, just squeak in advance. Duan Yun raised his eyebrows and said.

"Great!" Cheng Qingyan looked at the pricing on the back of the book, and asked Duan Yun, "How much are these books, I'll give it to you." ”

"It's all classmates and colleagues, it's normal to help each other, it's common to talk about money!" Duan Yun pouted and said, "Actually, there is not much money, you don't need to give it to me, if I have something in the future, maybe I will have to ask you for help." ”

"But ......"

"I really don't have much money, okay, let's study quickly. Duan Yun said, took out another English book from his schoolbag, handed it to Cheng Qingyan and said, "I don't know how long you have been learning English before, just start from the basics, this book is my sister's high school English book, let's start learning from this one here in the future." ”

The book in Duan Yun's hand is the English book of his sister Duan Fang's sophomore year of high school.

Although English has been the first foreign language in China since 1965, in fact, in the early 80s, there are still many schools in China where the foreign language is still Russian, and with the gradual introduction of English as a college entrance examination item in recent years, schools have begun to popularize English education on a large scale.

So when Cheng Qingyan went to secondary school, she only started to learn English in the last year of secondary school, and the English class was only for one semester, and the foundation was there, but the level was not high.

Later, before taking the adult college entrance examination, she also studied by herself for a period of time, and although her final English score was not high, she was lucky to pass the admission line.

Duan Fang's English textbook is in the second grade of high school, but for Cheng Qingyan, it is just right for her to study.

"Uh, that's great. ”

After Cheng Qingyan took the English book, she smiled and thanked her.

"Alright, let's start the class. Duan Yun sat next to Cheng Qingyan, picked up the book and turned the first page, and asked Cheng Qingyan, "Do you have studied this textbook before?"

"I've learned a little bit about this...... Cheng Qingyan said after looking through the table of contents of this textbook.

"Then that's easy to say. Duan Yun couldn't help but breathe a sigh of relief when he heard this, it seemed that he didn't have to teach Cheng Qingyan from the beginning, which saved a lot of time.

In Duan Yun's opinion, English is actually not difficult to learn, there are many words mainly memorized by rote, as for grammar or something, it only takes a few days to talk about it, if Cheng Qingyan has a good memory, then it will progress very quickly.

At a certain level, Cheng Qingyan has a certain level and can teach herself through radio or tape recorder teaching tapes, and at that stage, Duan Yun doesn't need to teach her by hand.

In the next time, Duan Yunjiao was serious, and Cheng Qingyan was also very serious, and all the things that couldn't be digested for a while were quickly recorded in the book.

It is not difficult to give a lecture to Cheng Qingyan, after all, she used to be a top student, and her learning ability is much stronger than that of ordinary people, and she can understand many things at a glance.

The two young figures are studying and communicating in the huge library, and Cheng Qingyan shows her strong desire for knowledge.

It wasn't until nine o'clock in the evening that the two of them finished tonight's class, and after Duan Yun sent her home, he lit a cigarette and left......

......

On the second day, Duan Yun was still wandering around the various workshops to check the production of the modified workpieces.

The processing speed of the workpiece is slower than Duan Yun expected, but fortunately, after testing, Duan Yun found that the heat treatment and turning accuracy of the workpiece currently processed are not bad, after all, this time there is the full support of the factory director and secretary, and the directors of each workshop also use the best technical master to cooperate with Duan Yun, so the quality of the workpiece is still very satisfactory to Duan Yun.

The milling machine used for modification is the milling machine that Gao Lei used to use during the night shift at the beginning, after all, the production task of a workshop is relatively heavy, and the good milling machine of other stations is basically 24 hours a day, and it can't be stopped at all.

However, although this is a milling machine that always fails, it actually has little impact on Duan Yun's modification plan, anyway, when rebuilding, this machine has to be rebuilt and loaded with many other parts.

The processing of the workpiece in the factory is progressing smoothly, and the circuit board shell on Duan Yun's side is also quickly made.

Duan Yun processed these electronic components out of his own pocket, and the money could not be spent in vain, so he simply went to the factory director to apply for technical transformation funds.

Today's Qin Gang and Duan Yun are in the 'honeymoon period', so they basically respond to his needs, first wave a big pen, and let the finance side advance 200 yuan of technical transformation project funds for him, as for the application report and the invoice for the purchase of parts, Duan Yun only needs to go back and make up for it.

Although two hundred yuan is not a big number in Duan Yun's eyes, it is equivalent to the salary of an ordinary worker in the factory for several months, and he is doing technical transformation for the factory this time, there is no reason to pay out of pocket, and it is easy to show his wealth after a long time, Duan Yun still doesn't want people to know the fact that he is currently rich......
