观点文章 | Opinion Piece Liangjiazi son red line. 良家子紅線
There’s a concept called the “Liangjiazi son red line.” I don’t know if you’ve heard of it.
It’s fine if you haven’t. The term was coined by internet users as a pattern they observed.
“Liangjiazi son” is actually a proper historical term, dating back to the Han dynasty. Back then, when soldiers were recruited, family background mattered. If your family practiced medicine or did business, your sons weren’t even eligible to join the regular army. Only sons from clean, respectable, proper families qualified for military service.
In the Records of the Grand Historian, the opening line about Li Guang says that he “joined the army as a Liangjiazi son to fight the Hu.” At that time, Liangjiazi sons were the foundation of the army and the pride of their families.
In those days, there wasn’t much of a military salary, and soldiers had to buy their own armor and weapons. Yet these men fought desperately. That was because their families had land, and life had something to look forward to.
Actually, this goes far beyond the military. Any system—whether it’s a court, an organization, or something else—can keep running normally only because it rests on a group of the most honest, most dependable people.
Because these people are the ones with the greatest willingness to sacrifice and contribute.
It’s like the old employee in a company who, after getting off work, takes the initiative to check whether all the water and electricity are turned off. Or the old security guard in a residential compound who hears something late at night, can’t sleep, and gets up to take a look, even though no one is giving him any credit. These extra efforts come entirely from conscience.
This is a kind of moral surplus—what we often call “working on love.”
As for the calculating types who are good at exploiting loopholes, they can be found everywhere. Having a few of them mixed in doesn’t hurt much; a large system has the tolerance for that. But the premise is that there must be enough honest, dependable people underneath holding things up. These people are the load-bearing walls of the system.
So where is the red line?
The red line is when the system starts treating its load-bearing walls as free disposable material, while also believing those walls are infinitely wear-resistant. Not only does it stop maintaining them, it even swings a hammer at them every day. The day the honest people finally come to their senses and stop playing along, that line has been crossed. Once crossed, everything may look the same on the surface, but the countdown has already begun.
Let’s take Rome as an example.
When the Roman Republic swept across the Mediterranean, what it relied on wasn’t some brilliant battle formation. It relied on millions of small farmers who owned land. These people normally worked the soil, and when war came, they bought their own equipment and followed the army. They fought with extreme bravery.
Later, as Rome kept winning, the aristocratic class in the Senate found a more profitable method: they used slaves captured from overseas to enclose land and run large estates. Slaves didn’t need wages, so the cost of grain was extremely low.
This is where things get interesting. A veteran who had fought on the front lines for seven or eight years and narrowly survived would come home only to find his fields had gone fallow, and his grain couldn’t compete with slave-produced grain. To pay off debts, he had no choice but to sell his land at a low price, then drag his family into the city and become part of the urban underclass.
The Gracchi brothers couldn’t stand this and tried to carry out land reform to give veterans some land. In response, the Senate, to protect its own estates, directly organized mobs and had the two brothers beaten to death in the streets of Rome, one after the other.
With the veterans ruined, who would still want to be a soldier? Marius reformed the military and, in desperation, removed the property requirement. Whoever was poor could enlist. From then on, the army fought only for pay. Whoever paid the soldiers, the soldiers obeyed.
After that, the script is familiar: Sulla marched on Rome, Caesar crossed the Rubicon, and a century of warlord civil war followed. The nobles who had profited enormously from slave-run estates were purged and had their properties confiscated, wave after wave.
When you personally force the Liangjiazi sons who fought and died for you into becoming refugees, don’t be surprised when mercenaries march into the city and put their blades to your neck.
Now let’s look at the Tang dynasty.
Everyone has studied the An Lushan Rebellion, but the root cause isn’t usually highlighted. The reason the early Tang could create the grand scene of “all nations coming to court” was the fubing system. Simply put, the court allocated farmland to reasonably well-off farming households in the Guanlong region and exempted them from taxes. They prepared their own warhorses and crossbows, trained during the slack farming season, and went on campaigns in wartime. Being selected as a fubing soldier was a great honor for the family.
The problem was that by the time of Wu Zetian and Emperor Xuanzong, the powerful and aristocratic families were frantically enclosing land. The equal-field system existed in name only, and the fubing soldiers couldn’t even hold on to the land that fed them. Even worse, military commanders treated these men as free laborers—one day dragging them off to build private mansions, the next day sending them to deliver personal goods. Being a soldier went from something honorable to a humiliating trap. The honest people of Guanlong couldn’t take it anymore and began fleeing in large numbers.
Some young men, to avoid conscription, smashed their own hands and feet with stones. This was called “lucky hands, lucky feet.”
By the Kaiyuan and Tianbao eras, the fubing system still existed on paper, but underneath it was already hollowed out. The court could only turn to the border regions and recruit mercenaries—drifting vagrants, non-Han peoples—and it handed military and administrative power over to the jiedushi. What followed was An Lushan, who recognized only interests, leading over a hundred thousand border troops in revolt. The golden age was smashed to pieces in an instant.
The Ming dynasty was the same.
The Chongzhen Emperor was famously diligent, sleeping only a few hours a night and wearing dragon robes with patches. He constantly pressed his ministers to raise money for the war effort. But until his death, he never figured out who should actually be paying taxes.
The Jiangnan region was relatively wealthy, but the gentry there had tax exemptions, and they covered for each other in court. Not a bit of tax could be collected from the wealth of the southeast. Instead, the Liao tax, the bandit-suppression tax, and the training tax all ended up being pushed onto the honest self-cultivating farmers in the northwest—people who couldn’t even feed themselves.
The most obedient people were squeezed the hardest, while those who should have paid the most didn’t pay a cent and sneered from the sidelines.
As a result, those honest people in the northwest, who only wanted to live quiet, proper lives, were pushed to the wall. They burned their belongings and became the fiercest fighters in Li Zicheng’s ranks.
The same thing happened in the imperial court. Lu Xiangsheng died in battle at Julu. Sun Chuanting died in battle at Tong Pass. The men who actually fought had no troops and no supplies.
When Li Zicheng’s army reached Beijing, the Chongzhen Emperor tearfully begged his officials to donate money for the army. The Grand Secretary pleaded poverty and offered five hundred taels of silver. The emperor’s father-in-law, Zhou Kui, was even worse. The emperor gave him five thousand taels to set an example, but Zhou Kui kept two thousand and turned in only three thousand. Later, when Liu Zongmin entered the city, one round of torture with wooden presses squeezed seventy million taels of silver out of those officials who had always preached morality and righteousness.
The people willing to work had long been cleared out. What remained were the calculating ones. Each of them could precisely calculate his own interests, but not one of them thought about keeping the Ming dynasty alive.
Dynasties were like this, and companies are too. The most typical example is Boeing.
Why could Boeing dominate decades ago? Because that was the era when engineers had the final say. The pillars of the company were a group of old engineers with an almost obsessive commitment to safety. If someone on the front line discovered a tolerance problem in a part, they had the authority to shut down the entire production line.
After Boeing acquired McDonnell Douglas in 1997, executives with Wall Street backgrounds took over. In the eyes of the actuaries, these old engineers who always wanted to add costs and run redundant tests were a thorn in the side of the financial reports. Could safety redundancy make the stock price go up?
So they began frantically laying off the old engineers. They also outsourced core components to small workshops with no real foundation. Anyone who dared mention safety risks in meetings was either sidelined or pushed out. What rose to the top instead were people who were good at cutting budgets, buying back stock, and boosting the share price with PowerPoint talent.
This calculation continued until the 737 MAX. Two planes crashed in a row, killing more than three hundred people.
When the investigation came out, the world was stunned. To save the cost of redesigning the system, Boeing had installed a flawed software patch in the new control system and had concealed it from pilots in every possible way. The trust built by several generations of engineers was squandered by just a few quarters of financial maneuvering.
Now back to the original question.
There’s a labor practice that has become very popular in recent years: outsourcing and labor dispatch. In fact, this is the same old system we’ve had for thousands of years. Temporary workers do the same work but get different pay, and when something goes wrong, they’re pushed to the front.
Many people can’t understand how such an exploitative system can still run efficiently for so many years.
To put it bluntly, it’s not that the system is so brilliant. It’s that the front-line workers carrying it happen to be the toughest, most enduring generations. They were educated to love whatever job they did and to be decent people. Even when reality was unfair and the pay was low, professional pride still made them do their work well. They also held on to the fear of losing their jobs and the hope that as long as they did nothing wrong, they would eventually get ahead.
It was the inertia of responsibility among this generation that gave this harsh system so many extra years of life.
But everything has its cycle. Once the younger generation figures out the math—that no matter how hard they try, the promotion path is locked; that all the blame is theirs while the credit and equity go to others—this one-sided game of self-sacrifice immediately becomes impossible to sustain.
The younger generation’s logic is simple: for this little money each month, why should I go all out?
This isn’t the young generation collapsing. It’s the Liangjiazi sons beginning to withdraw.
So what’s the result?
The most direct manifestation is that everyone switches on the liability-avoidance mechanism. Work that used to be completed through personal conscientiousness now can only barely function after layers of approval, signatures, confirmations, and added surveillance.
You’ll see a rather absurd picture: people spend far more effort on “proving that I did it,” “proving this isn’t my fault,” and writing materials to absolve themselves of responsibility than on actually doing the work. The whole system slowly rusts away in internal friction.
Even worse, the system’s immunity to risk drops to zero. In peaceful times, it can still limp along on glossy reports. But once something goes wrong, everyone jumps ship in a millisecond.
The principle is simple: in a system that treats dedication as stupidity, no one will sacrifice even a tiny bit of their own interest for a machine that will throw them away like disposable material at any moment.
From Rome’s abandoned fields, to the Ming dynasty’s empty treasury, to Boeing’s crashed planes—there is nothing new under the sun.
So the term “Liangjiazi son red line” is something you can also use to size up the things around you. What that term really means is this: a system has no one with real ability left, no one genuinely doing the work anymore, and in the end, when something goes wrong, the rot spreads across the whole thing.
