I Asked My Kids About Their Friends. They Replied with Marx and Yu Boya.

One evening after dinner, I tossed a question to my two children: "Tell me a friendship story from your own lives."

I expected the usual small stuff—borrowing half an eraser in class, high-fives on the basketball court. But after a quiet moment, they each handed me something far grander.

My daughter told the story of Marx and Engels. My son told the story of Yu Boya and Zhong Ziqi.

In that instant, our dining table felt like a miniature lecture hall. Two children, still young and unseasoned, had used two timeless parables to redefine for me—a grown adult—[修] the weight of the word "friend."

My daughter spoke first. She had just read about the Industrial Revolution in her history textbook, and her teacher had briefly touched on the birth of scientific socialism. She stumbled over some of the names but spoke with unusual seriousness: "Mom, did you know that when Marx and Engels first met, they didn't like each other at all?"

That was not the opening I had expected.

She explained that Marx came from an ordinary background and spent his life exiled by various governments, too poor to afford bread; Engels, by contrast, was the son of a factory owner, with estates and industry in his blood. In class‑conscious Europe, these two should never have crossed paths. Worse, when they first met in Cologne in 1842, Marx was busy attacking the Bauer brothers, and Engels happened to correspond with them—so Marx naturally lumped Engels into the "enemy camp." Engels later wrote in his memoirs, with characteristic understatement: "It was a very cold first meeting."

My daughter paused dramatically, like a little teacher milking the suspense: "But then Engels wrote a book called Outline of a Critique of Political Economy, and after Marx read it, he was completely won over."

The real turning point came in Paris in 1844. Engels, travelling from England back to Germany, made a detour to visit Marx. That time, they talked for ten full days and nights. The room filled with stacks of manuscript paper; the coffee on the table went cold, was reheated, and went cold again. They roamed from Hegel's dialectics to the English Chartist movement, from Feuerbach's materialism to the details of a workers' strike along the Seine. My daughter said: "Mom, they didn't just talk for ten days—they wrote for ten days. Every page had both their handwriting, and you couldn't tell who had written which line."

I found myself drifting into the scene. She continued: "Later, when Marx was writing Capital, Engels—who hated business—went back to work as an accountant in his family's factory just to help Marx. He did that for decades. All the money he earned went to Marx's family. After Marx died, Engels spent more than a decade sorting through the manuscripts, editing volumes two and three. He said it was Marx's book, and he was only the 'second violin.'"

My daughter ended with a line that struck me: "I think a real friend isn't someone you see every day. It's someone who does what they don't like to do, just for you."

My son couldn't sit still any longer. He had just learned the story of "Boya and Ziqi" in his Chinese literature class and knew it by heart. He jumped in: "Then let me tell you about Yu Boya and Zhong Ziqi."

"Yu Boya was an amazing guqin player, but no one understood his music. One day he was playing on a mountain, thinking of high peaks, and Zhong Ziqi walked by and said, 'Splendid! Soaring like Mount Tai!' Then Boya played flowing water, and Ziqi said, 'Splendid! Vast like rivers and oceans!' Boya was overjoyed—finally someone got his music. But later Zhong Ziqi died. So Boya smashed his qin, cut its strings, and never played again, because he said there was no one left in the world worth playing for."

My son finished, sat up straight with both hands on his knees, and added not another word. I asked him: "What do you think a 'soulmate' means?" He thought for a moment and said: "It means he doesn't have to speak, and you already know what he's thinking."

The two stories hung in the air for a few seconds. I looked at my children and suddenly realized: without meaning to, they had drawn me a complete map of friendship—one pointing to "the same path," the other to "the same heart."

The friendship between Marx and Engels is a model of "the same path." They shared a common ideal—liberating all of humanity, overturning the old order. The road was steep and long; someone had to carry the torch in front, and someone had to carry supplies in the rear. Engels gave up his own literary and scholarly ambitions to become the supply‑carrier; Marx endured poverty and exile to be the torch‑bearer. Their roles differed, but their steps were aligned. Their friendship was as solid as a steel bridge, strong enough to bear the weight of an era.

The friendship between Yu Boya and Zhong Ziqi, on the other hand, is the ultimate expression of "the same heart." They had no practical collaboration, no shared enterprise, barely any time together. Zhong Ziqi was only a woodcutter—he understood nothing of political economy or revolutionary platforms. But he possessed one rare gift: he could hear the intent in the music. Not the melody, not the technique, but the sigh of a soul wandering through mountains and rivers. After Ziqi died, Boya's qin fell silent forever.

In our own lives, we may rarely encounter both kinds of friendship. Most of the time, we meet companions who walk a stretch of road with us, or acquaintances who occasionally catch a flicker of what we mean. But these two children reminded me that great friendship is never out of reach. Marx and Engels began with coldness; Boya played alone for years before meeting Ziqi. All deep connections need the sedimentation of time and the serendipity of chance.

More importantly, these stories made me re‑examine my own expectations for my children. I had worried they wouldn't make enough friends; I had carefully arranged playdates through parent groups. [修] When a little friend snubbed them, I secretly fretted. But that evening, when my daughter said "doing what you don't like to do" and my son said "knowing without words," I put down the phone I had been clutching, and stopped thinking about which parent to text for the next playdate.

The quality of friendship never depends on quantity, nor on a perfect beginning. It can start like Marx and Engels—from an unpleasant first meeting—yet be forged over decades into the bedrock of a life's work. Or it can flash like Boya and Ziqi—a breathtaking glimpse, made eternal by that single moment of recognition.

If there were ever a real Atlas of Earthly Friendships, I would place these two stories at the very front. I want my children to remember: you don't need to please everyone. You only need, in the long journey of life, to meet one person willing to walk the same road, or one person who can hear your unspoken heart. Even one of those is [修] a generous gift.

And as a mother, my greatest fortune is not that I can pick their friends for them, but that I get to sit at the dinner table and listen to them tell me these stories—because [修] they've already begun to recognize what "great" really means.

That night, after the children had gone to bed, I carried the dishes to the kitchen and stood at the sink for a long time, staring into space. The two cups from dinner were still side by side on the table—one with a milk ring on the rim, the other without. I found myself thinking that, somewhere in some invisible time and space, Marx and Engels might still be bending over their manuscripts, and Boya and Ziqi might still be sitting face‑to‑face by the high mountains and flowing waters.

And I—just an ordinary mother—had heard both sets of music in the space of a single meal.

That was enough.
