0:00 A burly man nearly 1.9 m tall, blindfolded and relying on muscle memory, manually flies precise parts crucial to a fighter jet using a bench vise. What's even more astonishing is that on the back of the file, which is rapidly moving back and forth, stands a glass of water perfectly still, defying Newtonian's physics. This bizarre scene appeared in a national media report on master craftsman Fun Wei Mong. The report seriously claimed that this handcraft method created a processing tolerance of 0.00.68 mm, surpassing textbook standards by 100 times, a feat even the most advanced CNC machines could not match.
0:46 In the worldview of these propagandists, modern aviation industries, rigorous quality management systems and high techch automatic equipment seems to have vanished. They insist on dragging the cutting edge manufacturing industry back to the days of pure handcraft typical of an agriculture society. To create their imagined industrial myth, they ignore the laws of thermodynamics, crush the basics of classical mechanics, and even reduce the advanced process of fighter jet manufacturing into a mystical street performance. Such industrial romantism superficially praises frontline workers. However, at its core, it reveals a terrifying ignorance. Blindfolded filing is upheld as a standard, while the stillness of
1:32 the water cup is used as a testament to precision. Newton's tears and the collapse of thermodynamics, the physics knowledge shattered by handcraft. To debunk this lowquality industrial magic, we don't even need to delve into advanced materials mechanics. We simply need to flip through a high school physics textbook. In the official promotional speech, one of the most hyped numbers is the 0.0000.68 mm of machining tolerance, followed by the 3,000 of a millimeter, 3 microns in the subsequent video. To these propagandists who have likely never used a caliper or micrometer, precision is probably seen as something akin to slicing potatoes. As long as the
2:19 master's knife skills are good enough and their heart is steady, they can cut endlessly thin slices. But they probably have no idea what 0.68 mm or 0.68 microns mean in modern machinery. This is a microscopic scale that can make steel breathe. Metals have thermal expansion and contraction properties. Take the commonly used alloy steel in the aviation industry. For every 1° C increase in the temperature, 100 mm of steel will deform by about 1.2 microns. What does 1.2 microns mean? It's nearly twice the 0.00.68 mm that the propagandist brag about.
3:05 Imagine a real world machining scenario. A burly man 1.9 m tall and weighing 200 lb tightly grips a metal part with his large hands at 37°. Not to mention the heat transfer from the human body. Just consider the rough carbide teeth of the file performing intense back and forth friction and cutting on the metal surface. During this process, the heat generated by the friction will cause the parts temperature to spike by a few degrees or even several dozens degrees. Facing the laws of thermodynamics, the myth instantly collapses. During this machining process, the part has already deformed by several microns or even tens of microns due to thermal expansion. In the propagandist idealized narrative,
3:50 perhaps Master Fun truly filed out a 0.00.68 68 mm precision on the heated metal with some special ability. However, once he puts down the file, the metal battered and heated slowly cools down to room temperature and inevitably contracts. That so-called precision has long since vanished, and no one knows where it went after several decimal places. In the real world of ultra precision machining, to achieve submicron precision, the parts must be placed in extremely strict temperature and humidity controlled environments with continuous spraying of constant temperature coolant during processing. Afterward, they must rest in a standard 20° C environment, then be measured with a multi-million dollar
4:36 coordinate measuring machine. But in the CCP official media's footage, all these stringent scientific conditions are completely erased. They are left with only raw strength and the most mystical feel. It's like trying to carve on a walnut believing that holding one's breath and not exhaling will make it happen. If handcrafted submicron precision is ignoring thyodnamics law, then the ironic image of a glass of water balancing on the back of a file directly knocks off Newton's coffin lid. In the video and article, Master Fun is calm and composed, smoothly pushing and pulling the file on the bench vise. With a glass of water placed on the back of the file, the water remains perfectly still without a drop spilled. The propagandist likely thought this image
5:23 perfectly illustrates the immortal realm described in traditional Chinese martial arts novels where pedals can hurt with a touch and internal energy is so deep that the water doesn't stir. But this precisely exposes the ignorance these directors and writers have about mechanical cutting. The work of filing is far from wiping a glass with a cloth. The essence of filing is to use the hundreds or even thousands of extremely hard small teeth on the file to forcefully break the crystal structure of the metal part surface, peeling off iron fillings layer by layer. To complete this action, workers must apply two directional forces simultaneously. Downward pressure allowing the teeth to bite into the metal and forward thrust for physical sharing. When the file teeth strikes and tear into the hard
6:10 aviation steel, it inevitably generates highfrequency microscopic vibrations. When the file reaches a limit and the wrist pulls back to change direction, a macronysical joint must occur. This is a process full of violent aesthetics and destructive power. under such intense highfrequency vibrations and reciprocal joints. How could a glass of water without any fixed device stay balanced on the narrow curved back of the file? How could the water not spill and the cup not fall? The only way possible apart from zero gravity and space is that Master Fang's file simply didn't bite into the metal. He wasn't cutting. He was merely holding a file and lightly comically stroking the metal surface. To cater to the visual spectacle of the short video era and create a cheap
6:57 craftsman godlike effect, the propaganda agency went so far as to arrange for such useless untrained stunts. This performance may have fooled laymen, but in front of engineers and physicists, it completely tarnished the reputation of China's highest end equipment manufacturing industry. Denigrating CNC machines, a countermodern, self-indulgence, and disaster. In this absurd process of defying individuals, what's most chilling is not how hard Master Fun worked, but how the propaganda system in its frenzy to elevate his personal myth blankly degenerates the cornerstone of modern industrialization, CNC machines and automated equipment. There's a particularly jarring line in the report. This is the precision that
7:43 even CNC machines struggle to achieve. The precision is named after Fun Wayo, a Wenmo precision by Aviation Industry Corporation of China. It even has the person involved say machines are also made by humans, but we can create higher added value than machines. This forced phrase that places human labor above machines exposes the ignorance of the propaganda writers when it comes to modern aerospace industry practices. Let's return to the most basic industrial knowledge. What is the soul of modern manufacturing? Not some martial art master with extraordinary skills, but absolute standardization, modulization, and the interchangeability of parts. Over 200 years ago, American Eli Whitney proposed the concept of interchangeable parts while making
8:30 musketss, which is regarded as the true beginning of modern industry. Fast forward to the 21st century. When building a fifth generation stealth fighter such as the J15 composed of millions of parts, what is required? It relies on advanced five axis CNC machining centers, precision EDM wire cutting and industrial machines capable of stable output of submicron precision year after year in a 20° C temperature controlled workshop tirelessly and without emotional fluctuation. The machine doesn't just achieve this level of precision. What's even more frightening is that the machine ensures that the first 10,000 parts produced will be dimensionally identical to the first part. However, in the logic of this mainstream report, nearly 70% of the standard parts on the J15 fighter
9:16 jets are allegedly produced by the factory where Master Fun works and some of the fighter jet parts when precision cannot be achieved by CNC machines still require machinists to hand polish them. This is deeply unsettling in the precision of key components on the J15 carrierbased fighter jets which represents the core combat power of China's Navy and Air Force truly depends on an 1.88 m tall worker to hand polish them. This is certainly not something to be proudly celebrated in state media. It is a disaster for China's aviation industry and a severe systemic management failure. Imagine a fighter jet performing takeoff and landing missions on an oceangoing aircraft carrier is damaged due to high salt, humidity, and intense vibration with a
10:02 critical component breaking. The ground crew goes to the equipment store to grab a replacement part only to find that it doesn't fit or that it fits, but there's a gap. Why? Because original part was hand polished by Master Fang that morning when he was wellfed and in perfect form while the replacement was made by his apprentice or on the day Master Fun had a cold. A difference of 0.003 mm could cause a jet to be destroyed and lives to be lost. The propagandists through by portraying Master Fun as a machine terminator surpassing CNC machines. They were celebrating craftsmanship. In fact, they were insulting China's modern aerospace system built over decades with investment in the trillions. They reduced what should have been a precise system guaranteed by advanced
10:48 algorithms, servo, motors, and material science to an ancient belief of swordsmanship requiring the sacrifice of living people to forge a divine weapon. After shattering basic physics knowledge and industrial logic, the report finally reached its climax, the most delusional step, blindfolded machining. After Master Fun blindfolded himself and processed it, the precision reached 0.003 millimeters. This sentence instantly transformed the news report from the Industrial Manufacturing Journal to Supernatural Tales from Storytelling Monthly. Anyone who has worked with measuring tools in a workshop knows that precision machinery is essentially a tightly controlled closed loop system. Machining equals measurement equals feedback equals micro adjustment equals reme-measurement. machining to
11:34 measurement to feedback to micro adjustments to reme-measurement. So what does 0.003 mm or 3 microns mean? The diameter of an average human hair is about 60 to 100 microns. That means the thickness master had to file off the metal was roughly 12th of the width of a human hair. Such a microscopic removal is beyond the capability of human eye and requires tools like lever micrometer, caliper or optical instruments. Human hand nerves cannot precisely sense the tiny resistant changes of a few microns while enduring intense metal cutting friction. However, Master Fang was assigned a performance to blindfold and file by removing vision, cutting off measurement feedback, and relying solely on the so-called muscle memory. He could
12:21 supposedly hit a tolerance of 0.003 mm. This isn't about manufacturing a national treasure. This is clearly a street performer's trick. like a blind swordsman listening for the sound to locate their target in a martial arts drama. We can't help but ask, why would a national level propaganda agency be so enamored with such stunt performance that violates basic scientific principles? Why go so far as to package it as the highest form of national craftsmanship? To understand this, we must dissect the deeply ingrained agrarian aesthetics in the minds of these propagandists. Most of these people sitting comfortably in air conditioned offices have never even smelled the oil in a workshop. Their worldview and narrative framework are still stuck in an agriculture society.
13:07 In the narrative of agriculture civilization, success does not require complex systematic science. It only requires two things. Extreme physical suffering and an almost religious enlightenment. Therefore, in their writing, Master Fang must be portrayed as an aesthetic. He must turn his balcony into a practice room. He must break countless flies. He must practice immortal martial arts with a water cup on his head. He must frequently attend competitions out of town and never return home, even engraving his wife image on a medal to ease his longing. He must remain at the workbench even when his father is dying of pancreatic cancer. Sacrificing everything for that 0.003 mm precision. enduring great hardships, bearing
13:52 immense labor, abandoning family, and achieving physical sanctification. This is a modern version of the ancient Chinese legend, turning an iron pestl into a needle. In their view, precision isn't achieved through technological research and equipment iteration, but through workers making their palms bleed, sacrificing family happiness, and blindfolding themselves to cultivate immortality on their balconies. The tragedy of this deification logic is that it uses a false moral high ground and anti-intellectual acrobatics to hijack the true hard work of frontline industrial workers. It fails to give workers genuine respect and alienates them into industrial consumables that don't need modern tools, scientific feedback, or anything but the endless
14:39 exploitation of their own bodies. When blindfolding filing becomes a standard, science is sidelined. What remains is just a carnival of satisfying the small farmer's aesthetics of fantasy. Dearified screw and hidden true dignity in this lengthy magical realer style report. If blindfolded filing to 0.003 mm openly challenges modern physics, the latter part of the report which describes Master Fun's personal life and treatment is a cruel exploitation of the real living conditions of industrial workers. There's one particularly classic emotional segment in the report. After Master Fang became wellknown in the industry, a private company offered him a salary of 480,000 yen per year.
15:25 However, at that time as the top national craftsman who would handcraft core fighter jet components, his monthly salary was only a few thousand yen. How did Master Fong's mother respond to this huge salary disparity? She invoked the highest directive from the older generation. Your father said we are the working class. As long as we have enough to eat, that's enough. Money isn't everything. Even if they offer more, you can't go. You should stay at Shenyang Aircraft Corporation and do a good job. We must earn face for the aviation people. Even when Master Fun's father was terminally ill with pancreatic cancer, his last words were still grandous. The path I chose is the right one. These words were carefully written by the propagandist as the most valuable
16:12 ideological high ground, hoping to move the readers to tears. However, anyone with even a basic understanding of modern corporate management and human decency would feel deeply sorrowful upon reading this. In this national craftsman narrative logic, a top mechanical talent representing China's highest level of equipment manufacturing capable of manually achieving precision beyond CNC machines. His labor value is reduced to have enough to eat. This is the most naked form of exploitation during the primitive accumulation of capital. It is spiritual manipulation disguised under the cloak of patriotism. The propaganda system tries to use this distorted worldview to tell and all industrial workers, look, even highlevel technicians capable of making fighter
16:57 jets don't care about money. They only care about dedication. What right do you ordinary workers have to complain about low wages, long hours, and poor treatment? They use the National Craftsman Label to mask the serious undervaluation of technical talents by the rigid salary system. When a private enterprise can offer a 480,000 yen annual salary for this craft, the colossal entity, which claims to represent China's highest industrial level, can only pay its core technical staff with a meager monthly salary of a few thousand yen along with a later dispersed 5,000 expert subsidy like a charitable handout. This is not only a disrespect for knowledge and skills, but also an outright trampling of market principles. When we peel away
17:43 this industrial romantism and remove the acrobatic disguise of blindfolding filing and water cup not spilling, what we see is a perfect tool forcefully placed on a pedestal. Master Fun has been stripped of the worldly desires and decent life that a modern industrial worker should have. Instead, he is crafted into a rust-free screw who only knows sacrifice and doesn't know how to ask for anything, even having to force a smile when his family members passes away. Behind this deification movement lies the heavy and genuine demands of the hundreds of millions of frontline industrial workers in China. What they need is decent pay that matches the value they create. An 8-hour workday with weekends off and allows for normal family life, comprehensive occupational safety and medical insurance and the
18:30 dignity of being treated as a human under a modern corporate management system, not as a human CNC machine to be used up. When a country's industrial backbone is still supported by such a small farmer mentality, when the fighter jets, the pinnacle of technology, still rely on workers performing acrobatics to guarantee precision, this is not only a shame for the propaganda system, but also a tragedy for the entire industrial system.
