The Grandmother in the Siheyuan

Chapter 131 Legacy
The gathering of this group of old engineers and scientists was equivalent to an academic seminar. The First Ministry of Machine Building attached great importance to it and arranged a conference room for it. They thoughtfully prepared a lot of sofas instead of hardwood chairs, and there was no shortage of tea, dried fruits, snacks and cigarettes.

"Old Liu, you still have the same old problem. You're always late."

Liu Hua's grandfather laughed: "What do you know? The heavyweights always appear last. How can you compare with me, Old Zhao? You are now researching military vehicles. It just so happens that my grandson has solved this problem. You should be counted as my grandson's generation."

"Ha ha ha ha."

Grandpa Liu Hua's words caused everyone to burst into laughter. They naturally knew that it was the all-terrain assault vehicle designed by Liu Hua.

"Old Zhao, you are not up to par." Another old man said jokingly, "You are not as smart as the kids. You tinkered with it, but in the end it is still a jeep. Look at the design of the kids. They are at least fifty years ahead of you."

Lao Zhao did not refute: "Yes, his design is indeed very advanced, but don't you think it is not suitable for today? I am still working hard for motorization. His design is simply the mechanization of the entire army. We currently do not have the strength to realize it."

An old man nodded, but looked at Liu Hua: "This is your kid who designed the all-terrain vehicle, right? Tell me what you think?"

The other elders looked at Liu Hua. Liu Hua thought for a moment and said, "Our country's army is very large now, but I think with the development of technology, it will not need to be so large in the future. It will definitely be streamlined. After the streamlining, each unit will be an elite force, and they need to be equipped with the best equipment."

"You're talking about the future, what should we do now?"

Liu Hua smiled and said, "Now we should focus on equipment. This kind of all-terrain vehicle should be equipped to border guards and elite troops. It would be best if we can establish an all-weather emergency force."

“What does it mean to have an all-weather emergency response force?”

"A team that can conduct high-intensity combat at any time and in any situation, 365 days a year."

"The requirements are very high." Grandpa Liu Hua nodded with a smile: "This kind of elite force requires the efforts of all our military workers. They deserve the best equipment."

Old Zhao nodded with satisfaction: "Your grandson's idea coincides with the plan we are making now."

As the conversation deepened, Liu Hua took the thermos and poured water for everyone. He was the youngest among all the people present, so he was willing to serve everyone.

Everyone first talked about their feelings, joked about each other's physical condition, recalled the years when they fought together, and taught their disciples or grandchildren.

After chatting for about an hour, everyone started to share with each other the difficulties they encountered at work.

Every time a question was raised, these older engineers did not answer it, but let the young people express their opinions first.

Since Liu Hua is not from this industry, he could only answer from a side perspective, but after listening to all the young people's answers, he felt that they were all similar.

Because not every question was relevant to the profession, and Liu Hua was also deliberately hiding his shortcomings, so he was not outstanding. "Old Liu, your grandson is good, worthy of being the youngest engineer." An old senior smiled and said, "Although he is not in our industry, his answers are meaningful. Why not transfer him to our factory?"

"Go." Grandpa Liu Hua said directly with disdain: "If you want to be transferred, you can't be transferred to my side. Why must you be transferred to your factory? You are a researcher of logistics support equipment. What's the point of that?"

There is also a chain of contempt in relationships. Liu Hua smiled. When these people get together, there will always be high and low ones. Even if there aren't, everyone will rank them one, two, three, and four.

"I have a problem here." An old man asked seriously, "When processing propellers or nozzles, we always encounter problems such as not being smooth enough or not being precise enough. Liu Hua, you are a mechanical designer, do you have any solution?"

Liu Hua looked at his grandfather in disbelief. This was obviously the design and manufacture of aircraft. Nowadays, the aircraft designed and manufactured by our country must be fighter jets with a very high level of confidentiality. So could he answer this question?
Grandpa Liu Hua nodded: "It's okay, go ahead and tell me, I believe you know the rules and won't talk nonsense everywhere."

The old engineer who asked the question nodded and said, "Yes, you have already stepped into this field. The Type 62 all-terrain vehicle you designed has been partially put into service and has received a lot of praise."

Liu Hua frowned and thought about it. Nowadays, our domestic machine tools are not able to achieve high-precision production. Therefore, if you want to produce high-precision parts such as propellers or nozzles, you need an eighth-level worker to do it by hand. However, in this case, not only is the output low, but the quality is also high and low.

Suddenly, he had an idea and remembered that he had seen a video in his previous life. It talked about how Boeing produced these parts. It was said that this was a technology of our country, a very ancient technology.

Liu Hua closed his eyes and tried hard to recall what the technology was. Suddenly he saw the national emblem hanging in the room, and he immediately remembered.

Seeing the smile on his face, the senior who asked the question said with a smile: "It seems that you have figured out the answer. Tell us and let us see it."

Liu Hua nodded: "In fact, this technology has already existed in our country, and it is very mature."

The old man shook his head and said, "Impossible. We have tried several methods this year, but none of them can achieve the desired effect. We have tried every possible method in China. The only effective method is to use high-level workers for processing, but our demand is very large, and this method alone cannot meet the demand."

"Our ancestors created very exquisite bronze wares," Liu Hua said with a smile. "Nowadays, we can see them in major museums. They are not only exquisite, but some of them are also very precise."

Everyone in the room was shocked. They tried all kinds of modern processing methods, but they didn't expect Liu Hua to mention a very ancient method.

"Our ancestors used the lost wax method to make bronze ware." Liu Hua smiled and said, "I believe that if you consult experts in this field, you should be able to achieve the goal of large-scale production."

The old man nodded and said, "I have visited the bronze artifacts in the museum. They are indeed very exquisite. The patterns and texts on some of the bronze artifacts are also very complicated. The processing is no less than that of today's precision parts. It seems that the lost wax method is indeed a feasible way."

Liu Hua nodded: "Yes, it's the legacy of our ancestors."
