The draft paper was full of data and rectangular patterns, with straight and thin lines outlining it. Fang Yu took one look at it and immediately felt the charm of this draft paper.
The charm comes from the level of science.
"Um...this is the overall structural design of the portable lighting source. Why, are you curious about this thing?" Yu Hua, who was packing his things, raised his head when he heard Fang Yu's question and glanced at the draft paper. There was nothing.
Cover and hide, explain the truth generously.
"You can also draw structural diagrams?!" Fang Yu was shocked, her eyes widened, and there was a hint of wonder and disbelief in her words. She is a person who has seen the world, and she obviously knows what Yu Hua said about the overall structural design, which translates to "structure"
picture.
Structure diagram!
Fang Yu once had the good fortune to see the blue drawings regarded as the biggest secret in the hands of foreigners during a visit to the Shanghai Machinery Factory.
The blue drawing is called a blueprint. It depicts the equipment structure, labels the equipment size data and materials used, and contains very important drawing standards. Those Western engineers attach great importance to equipment structure blueprints and never install equipment without factory management.
If you forcefully ask for your hand, the other party will leave angrily.
If tough measures are taken, those Western engineers will even burn the blueprints of the equipment structure.
From this we can see the value of structural diagrams.
Fang Yu had only seen it from a distance and had an occasional understanding of it. However, she never expected that a structural diagram would appear in front of her eyes.
"Yu Hua, you can actually draw structural diagrams?" At the same time, Zhou Yuan, who was taking notes in English with his head down, immediately raised his head after hearing Fang Yu's words, quickly picked up the draft paper on the table, and took it
At first glance, a look of shock appeared on his face. He looked around and lowered his voice deliberately.
Obviously, Zhou Yuan is also a person who has seen the world and understands the weight of this structural diagram.
"Uh... Isn't it okay if you have some hands?" Yu Hua took out the things he was going to do for dinner from the drawer, looked at the two people with shocked faces, and responded with some confusion.
What can be shocking if you draw a structural diagram of a light source system with no technical content?
The difficulty of this thing is equivalent to nothing, it is as simple as eating and drinking.
"..." Fang Yu was confused for a moment by the rhetorical question, a little doubtful about life, and subconsciously looked down at his hands.
Just have hands?
Then why can’t I draw a structural diagram?
Zhou Yuan held his forehead and was speechless. He opened his mouth, but didn't know what to say: "..."
"What's wrong with you two?" Looking at the two people's reactions, Yu Hua asked with doubts.
Looking at Yu Hua's puzzled and confused look, Zhou Yuan showed a helpless look, glanced at Fang Yu, took a deep breath, and said seriously: "Yu Hua, do you really not understand, or do you pretend not to understand? The structure diagram was made in Japan.
One of the important secrets strictly guarded by Chinese and Westerners, this technology has always been blocked by us in China. The few machine factories that can obtain structural drawings can only install equipment with the help of Western engineers. The structural drawings contain very important information.
The mapping standards and related data, this is the...knowledge blockade they have imposed on us."
The words were heavy at the end.
Zhou Yuan, who came from an extraordinary background, obviously knew more than Fang Yu, a young rich woman.
Knowledge blockade!
This is one of the blockade measures implemented by Japan and the West against China today.
From the end of the Qing Dynasty to the beginning of the Republic of China to the end of the Republic of China, the entire China has been subject to a blockade of knowledge by Japan and the West. Knowledge about the revolution can be read and copied, but all key knowledge about science and industry is blocked.
Structural diagram production is one of the important contents under the knowledge blockade method.
Regarding the concept of China, Western countries like a stable and open commodity market rather than a competitor that can compete with them on the same stage. Japan does not want China to become stronger at all.
Blocking the relevant knowledge of structural drawing production means blocking the pace of China's industrial development from the basic level. In this era, if you want to develop any mechanical equipment and military weapons, you must first draw drawings and then conduct research and development.
If you can't even master drawing production, where will the development opportunities come from?
Today's Chinese industry is in the darkest period in history, and the road to the future has been directly strangled!
All kinds of factories and machine factories opened in coastal areas can never get rid of the situation of being controlled by others. The machines are purchased from the West, the technology is Western, and even the factory technical consultants have to hire Western engineers.
China's industry has been unable to develop by leaps and bounds and cannot keep up with the same level as the world. Apart from war and other factors, this unknown potential reason cannot be ignored.
After listening to Zhou Yuan's explanation, Yu Hua frowned slightly and finally understood why Fang Yu and Zhou Yuan were shocked.
What shocked me was not the lighting system design, but the equipment structure diagram I drew.
"Really?" Yu Hua took a deep breath, relaxed his hands, and his happy mood disappeared in an instant. He looked at Zhou Yuan and Fang Yu with heavy faces, and said something he shouldn't have said.
Yu Hua didn't want to doubt it, but he couldn't help but want to be sure, because this was something that had never been told in history.
Regarding the history of China's modern national industry, there is only a very short content in history books. It is summarized as the reasons for the tortuous development of China's modern national industry. From the late Qing Dynasty to the end of the Republic of China, the tortuous development process is explained.
"Everything is true and absolutely no lies. My family has opened a textile factory in Tianjin Wei. All the textile machines in it are imported from the UK. There are two British engineers responsible for technical maintenance and later repairs. When the equipment fails, they
We never let our workers be present." Zhou Yuan looked at Yu Hua and said in a deep voice.
Fang Yu nodded seriously: "I have visited the Shanghai Machinery Factory. The mechanical equipment installed there comes from Germany. There is a German engineer who carries blueprints. Anyone who approaches him will yell at him. If he asks for it by force, he will leave immediately."
"Knowledge Blockade."
After listening to this, Yu Hua silently recited this new and unfamiliar word. He had a completely new understanding of this era in his heart. He turned his eyes to Zhou Yuan and continued to understand: "Zhou Yuan, what about our classmates who are studying abroad? I don't think so.
As for none of them, can they make blueprints?"
Fang Yu looked at Zhou Yuan. She only had a preliminary understanding of the knowledge blockade, but she didn't know the deeper things.
"Everyone who learns this is dead..." Feeling the gaze from Yu Hua, Zhou Yuan was a little silent. After two seconds, he revealed the secret that was supposed to be kept.
