He Chengshan's face showed some complicated expressions, like a child stealing candy and eating it was discovered by an adult. He nodded to the student first and said, "It's okay, tell your mother, it's okay to be late." ”

"Thank you, Mr. He." The student bowed to He Chengshan and said, Beijingers are still very particular about politeness.

Seeing the student turn to leave, He Chengshan turned his head and said to Wei Dongqi embarrassedly, "Uh...... Xiao Wei, this, they are all children in the factory, everyone is more polite......"

Wei Dongqi had mixed feelings in his heart, and he didn't know what to say. Previously, he and Lin Zhenhua both felt that He Chengshan's tutoring of the children was an obligatory act, and the old gentleman wanted to give full play to his spare heat and make some contributions to the society. But now that we know that this kind of make-up class is actually charged, its nature is completely different. Wei Dongqi didn't think there was anything wrong with making up classes for others and charging some make-up fees, but with He Chengshan's identity, age, and such a weak body, he was still earning this kind of extra money, which couldn't help but make people feel so sour in their hearts.

Everyone went upstairs in silence, He Chengshan took out the key and opened the door, beckoned Wei Dongqi and Lin Zhenhua to sit down on the sofa, and dragged a chair with a back to sit opposite them. Mrs. He poured tea for everyone, then went back to the kitchen to get a basket of vegetables, and prepared to go out to buy vegetables.

"Master, you don't have to bother to buy groceries, we can just sit here casually." Wei Dongqi said.

"Let her go." He Chengshan said, he looked at Wei Dongqi and Lin Zhenhua, and asked, "You two, are you okay this afternoon?" ”

"It's fine." Wei Dongqi said.

"If it's okay, stay here and eat." He Chengshan said, and then, he turned his head and said to his wife: "Go to the black market to buy two catties of better pork ribs, and I will cook it myself and make sweet and sour pork ribs for Xiao Wei." This is what I promised him more than ten years ago, Xiao Wei can eat meat, I know this. ”

"He Lao ......" Wei Dongqi's nose was a little sour, he vaguely remembered that He Chengshan did say this, saying that Wei Dongqi was welcome to be a guest at his house, he was good at making sweet and sour pork ribs.

Wei Dongqi still remembers that at that time, he was only in his early 30s, and it was the time when he could eat meat, and under the conditions of that year, how could it be possible to eat meat often? Whenever there was an opportunity to have a dinner, He Chengshan and some other veteran comrades often ate very little, so that they could let the young people eat more. Wei Dongqi didn't realize this until a long time later, and he always thought that the old gentlemen didn't eat well.

Mrs. He went out to buy vegetables, Wei Dongqi hesitated for a while, and finally asked, "Old He, what's the matter, isn't your unit doing well?" ”

He Chengshan shook his head and said: "Our unit is okay, it is not enough to be above it, it is more than enough to be lower than the bottom, at least the salary can be paid." My wife and I are both retired, and the pension of the two of us is nearly 200 yuan a month, and life is completely fine. ”

"Then what are you...... Children need money? ”

He Chengshan shook his head again and said, "No, they all have jobs and don't need my subsidies." ”

Wei Dongqi couldn't understand: "Old He, since you don't need to subsidize your children, then your old couple has a pension of 200 yuan, and their lives should be very good." But ......"

He gestured around, meaning self-explanatory.

Although He Chengshan's home is not a family with four walls, it definitely does not look like a family of an old engineer with a pension of 200 yuan. The TV is black and white, the washing machine is single-cylinder, and the clock is the old-fashioned little alarm clock with a hen pecking rice, rather than the "combasi" quartz clock that is so popular nowadays. The sofa that Wei Dongqi and Lin Zhenhua sat on has a history of at least 20 years, and Wei Dongqi knows this kind of sofa very well, which is a sofa made by the workers in the factory, and even the springs are bent by themselves with steel wires.

The old couple has a pension of 200 yuan, and they should be very rich in this era, why does He Lao's family seem so poor, and He Lao still has to go to make up lessons for the children to earn extra money?

"Alas, I'm not afraid of your jokes when I say it." He Chengshan showed a self-deprecating smile on his face and said, "When people are old, they always want to do something." I've been retired for almost 10 years, and I don't like to play cards or chess, so I love to write. After I finished writing, I still wanted to let others see it, so I wanted to find a publishing house to publish it. ”

"That's a good thing." Lin Zhenhua interjected, "Have you found a publishing house?" He Chengshan said: "I found several of them, but I was reluctant to give them at first, saying that they were too niche and had no market." In the end, the trust relationship found a family and promised to give a book number, which can be released, but it must be underwritten by itself and have to pay the book number fee. If you calculate three or two, you need at least 10,000 yuan. No, my old couple is frugal, and I try to earn some extra money, just to make up the publishing fee. ”

"How can this be done?" Wei Dongqi was a little angry, he had never published a book, so he naturally didn't understand the rules. In fact, the fact that publishing houses require underwriting was not a new thing at the time.

Lin Zhenhua knows a little bit about this, in the era he experienced in his later life, whether it is a publishing house or an academic journal, it is basically clearly marked with prices, unlike now, how much has to be covered up, and it looks a bit Sven in the name of underwriting.

"He Lao, what kind of book did you write?" Lin Zhenhua asked. In his thoughts, the old gentleman has a little hobby, or a little vanity, which is understandable. The matter of 10,000 yuan, depending on his friendship with Wei Dongqi, it doesn't hurt to do it for him, you can't let the old gentleman earn his own publishing funds at such an old age.

He Chengshan walked into the house, took out a few manuscripts, and handed them to Wei Dongqi and Lin Zhenhua respectively. This is a manuscript written on 400 sheets of manuscript paper, and at first glance, it must be two or three thousand pages, or at least seven or eight hundred thousand words. Wei Dongqi and Lin Zhenhua took the manuscript, looked at it fixedly, and couldn't help but be stunned. I saw that on the cover of the manuscript, there was a line of italic characters:

Fracture Mechanics of Low-Temperature Materials.

"He Lao!" Lin Zhenhua's hand holding the manuscript began to tremble, and He Chengshan's thin body suddenly turned into a Mount Tai in Lin Zhenhua's eyes.

"This is the book you're going to publish?" Lin Zhenhua asked in disbelief. He just flipped through a few pages, and although he was not very clear about some concepts related to cryogenic materials, he could also see that the writing of this book was very rigorous, and it had extremely high academic value and application value.

"Clumsy, clumsy." He Chengshan said with some embarrassment, "There are a lot of opinions in it, but it's just the words of one family." My idea is to print it out and let my peers see it and give advice. By the way, Xiaolin, you and Xiao Wei are also colleagues, right? ”

Lin Zhenhua nodded and said, "Yes, Old He, I am a colleague of Director Wei. I've also learned a little bit about fracture mechanics, but I don't know anything about low-temperature fracture mechanics. ”

"Low-temperature mechanics are hard to do." He Chengshan said, "The main reason is that the experiment is difficult, and there are few places in China that can do this kind of experiment. A lot of what I've written in this book is just a theoretical guess, and it would be nice if there were experiments to verify it. ”

"Manager Lin, He Lao's book is very valuable!" Wei Dongqi also spoke, "This book is instructive for all those who are engaged in low-temperature materials, you see, can our company support He Lao?" ”

"Director Wei, you and I have thought together." Lin Zhenhua said, he turned to He Chengshan and said, "He Lao, our company will pay for the publication of this book for you." Isn't it to be underwritten, how many volumes are underwritten, our company is all-inclusive. ”

"How can this work?" He Chengshan waved his hand again and again, he didn't understand the relationship between Lin Zhenhua and Wei Dongqi, and simply thought that Wei Dongqi must be Lin Zhenhua's leader based on his age. He said to Wei Dongqi in a reproachful tone: "Xiao Wei, you are now a director, you must not engage in this kind of fake public and private thing." ”

"He Lao!" Wei Dongqi said, "I forgot to introduce to you, this is Comrade Lin Zhenhua, the executive deputy general manager of our Hanhua Heavy Industry Group Company, and he is my leader." ”

"Deputy General Manager?" He Chengshan looked at this young and abnormal deputy general manager in surprise.

Lin Zhenhua said with a smile: "Old He, don't call me Manager Lin, you can just call me Xiaolin, in front of you, I am really a primary school student." As for the publication of funds, this is definitely not a fake public business, and publishing this book to you is the biggest public business, not only the official business of our Hanhua Heavy Industries, but also the official business of our entire national chemical system. ”

"Really?" A smile appeared on He Chengshan's face, "Xiaolin, you mean that this book is valuable to your company?" Wei Dongqi said: "Old He, I came to see you this time just to report to you." We are currently carrying out the technical reserve of 800,000 tons of ethylene equipment, and the development of ethylene three machines is our top priority. To tell you the truth, in terms of cryogenic materials, it is now an obstacle that we have encountered, and we have dozens of people working in this direction. Your book is not an ordinary help to us. ”

"800,000 tons of ethylene!" He Chengshan's eyes flashed, he looked at Wei Dongqi, then at Lin Zhenhua, and asked: "Really, what kind of enterprise do you dare to engage in 800,000 tons of ethylene?" ”

Lin Zhenhua said: "He Lao, there is nothing difficult in the world, as long as you are willing to climb." With our current strength, it is impossible to get 800,000 tons of ethylene out at once, but we can now start to tackle some basic technical problems. You just mentioned the problem of low-temperature material experiments, and we at GCA Heavy Industries have built a low-temperature materials laboratory, which can conduct material experiments in the range of minus 40 degrees to minus 120 degrees. ”

Wei Dongqi added: "Mr. He, do you remember that we studied the two-parameter Weibull distribution function of the fracture toughness of 16MnDR. In the first two months, the technicians of our institute have completed the experiment of the entire low temperature region, fitting the distribution curve family, and the results are very close to your theoretical prediction back then. ”

"Do you have detailed data?" He Chengshan asked excitedly.

"All the data is there. We are now validating the parameters of the lognormal distribution, and we expect that the results will be available soon. At that point, we can compare the two distributions and determine which one is closer to the real situation. ”

"Great, great!" He Chengshan said repeatedly, "With these experimental data, many of the statements in my book can be clarified. So, are you really going to make 800,000 tons of ethylene? ”

Lin Zhenhua smiled: "This is still false. Mr. He, if your physical condition allows, I would like to hire you as our technical consultant. ”

Before Lin Zhenhua came to He Chengshan's house, he just felt that he was a senior in the chemical equipment industry, and it was appropriate to come and visit. But when he saw the manuscript written by He Chengshan with nearly one million words, he was shocked, and immediately made the decision to hire He Chengshan as a consultant.

He Chengshan's knowledge and experience are only one aspect. What touched Lin Zhenhua the most was his dedication to his career. People like He Chengshan deserve lifelong honor and the most superior treatment.

He Chengshan replied almost without thinking about it: "I'm in good health!" Xiaolin, if you allow it, I want to go to you immediately, it doesn't matter if the consultant is a consultant or not, I just think that if you really want to make 800,000 tons of ethylene, my old bones should be of some use to you. ”

Lin Zhenhua said: "Old He, don't worry, our work there is not finished, the key is whether your body can keep an eye on it." In this way, I will arrange for someone to contact you as soon as possible, let you go to Beijing Hospital, or Xiehe, to do a comprehensive physical examination, treat some problems, and then go all out to work, what do you think? ”

"This is completely unnecessary, our factory will also arrange for retired employees to check their bodies every year, and my body is fine." He Chengshan argued.

Wei Dongqi said with a smile: "He Lao, you should go and check your body in a down-to-earth manner, I remember you told me back then, saying that you want to see the completion of the domestic ethylene plant with your own eyes, I believe that this day will not be too far away." ”

As soon as everyone was talking about this, Mrs. He entered the house with a basket of vegetables, and as soon as she entered, she felt that the room was filled with a joyful atmosphere, and she couldn't help but look at her husband in surprise.

He Chengshan stepped forward, took the vegetable basket from his wife's hand, and said with a smile: "Old mother, haven't you always wanted to go to the south to have a look, now that you have a chance, Xiaolin and Xiaowei invite us to Xunyang." ”

"What are you doing in Xunyang?" Mrs. He was a little dazed.

He Chengshan said heroically: "Go and engage in ethylene, big ethylene!" What is 110,000 tons, let's do 800,000 if we want to do it! ”

Speaking of this, he turned back to Wei Dongqi and Lin Zhenhua and said, "You two sit down and watch my old man make sweet and sour pork ribs for you." Don't think that I only know how to work with low-temperature materials, I am also very good at high-temperature materials. ”
