A Madman's Diary by Lu Xun
Quick answer: A Madman's Diary by Lu Xun: full summary with the ending, the cannibalism metaphor explained, themes, and why this 1918 story began modern Chinese fiction.
A man reads late into the night in an old Chinese town and becomes convinced that his neighbours, his doctor and finally his own brother are planning to eat him. A Madman's Diary, published by Lu Xun in the magazine New Youth in 1918, is routinely called the first modern Chinese short story: the first major fiction written in the living vernacular rather than the classical literary language.
Students search for it because it anchors every syllabus on modern Chinese literature; general readers arrive through its terrifying central image. The story rewards both. It is a horror story, a political pamphlet and a formal experiment at once, and its last three words are among the most quoted in twentieth-century fiction.
The story in brief, ending included
A short preface, written in classical Chinese, frames everything: the narrator visits two brothers, old school friends, and learns one had suffered a spell of madness, now fully cured, the recovered man has since taken up an official post, and is given the madman's diary. The diary itself, thirteen fragments in plain vernacular, then takes over. The diarist notices the Zhao family's dog looking at him strangely; then the neighbours; then children, who could not possibly hate him unless taught. Slowly he assembles his theory: the people around him are cannibals, and he is next.
The evidence mounts in his mind. A tenant reports villagers who beat a wicked man to death and ate his heart and liver; the doctor who takes his pulse seems to be assessing him for weight; his own elder brother speaks in ways that fit the pattern. Sleepless, the madman opens the classical histories to check, and finds the books' every page scrawled between the lines of virtue and morality with two words: eat people. He recalls his little sister, dead at five, and realises his brother managed the household then; perhaps her flesh went into the family's food, perhaps his own meals have made him a cannibal without knowing it. His attempts to convert others fail. The diary breaks off with a hope and a plea: perhaps there are children who have not yet eaten human flesh, and then the final line, save the children. The preface has already told us the sequel: the madman recovered, and joined the system that eats.
The characters
The cast is a paranoid's map of an ordinary town, which is the point: everyone is normal, and that is the accusation.
Themes: the feast of the old order
The cannibalism is a metaphor, and Lu Xun leaves no doubt about its target: the traditional Confucian order, whose vocabulary of virtue and morality writes eat people between its own lines. The old society, the story argues, consumes its members, the young, the weak, the different, through hierarchy, ritual obligation and family authority, and everyone participates: the diarist himself may have eaten his sister's flesh. Guilt in this system is not individual but dietary; you are fed complicity before you can refuse it.
The sharper reading turns on the preface. Written in the classical language the diary rejects, it reports the madman cured and employed as an official. The frame does not soften the story; it completes the horror. Sanity, in this world, means rejoining the eaters, and the classical prose of the preface is itself the sound of the system swallowing the episode. The diary's final cry to save the children thus reaches the reader already refuted, which is why it lands as a challenge rather than a consolation.
The craft: paranoia as method
Lu Xun borrowed his title and device from Gogol's Diary of a Madman, but redirected the machine: where Gogol's clerk descends into private fantasy, Lu Xun's madman ascends into social diagnosis. The technical trick is calibrated unreliability. The diarist misreads dogs, glances and pulse-taking, and yet his one central claim, that this society devours people, is the story's sober thesis. The reader is trained to discount him and then forced to concede him, and that oscillation is the experience of the story.
The two-language frame is the other masterstroke: classical Chinese for official reality, vernacular for the truth-telling voice, so the medium carries the politics. And the fragment form earns its keep, thirteen entries of uneven length, dated by mood rather than calendar, letting logic gather the way obsession actually gathers. Writers adapting the design should keep the diarist wrong about details and right about the pattern; unreliable narrators bore when they are simply wrong, and preach when they are simply right.
Why this story started a literature
Lu Xun, trained as a doctor in Japan, famously abandoned medicine after deciding that China's sickness was of the spirit, and A Madman's Diary was his first blow: published in New Youth in 1918 at the height of the New Culture Movement, it demonstrated that serious art could be made in the spoken language of ordinary people. The story's attack on tradition became a founding document of modern Chinese thought, and its author the conscience of the era. It opens his 1923 collection Call to Arms, whose preface, with its image of sleepers in an iron house, is often read alongside this story as a single argument about whether waking people is mercy or cruelty.
What poets can take from this
- For exams, always read the classical preface against the vernacular diary; the cure reported there is the story's darkest event.
- Quote the discovery scene idea precisely: the histories preach virtue and morality while eat people runs between the lines.
- Name the source and the swerve: Gogol supplied the diary device, Lu Xun aimed it at society rather than one clerk's mind.
- Use the sister's death as the hinge where accusation turns into self-accusation; complicity is the theme's sharpest edge.
- As a writer, let an unreliable narrator be wrong in every detail and right about the pattern; that split creates the reader's vertigo.
- Consider a frame that quietly defeats your narrator's hopes before the narration begins.
Try it yourself
Write a story as diary entries by someone who has noticed a monstrous pattern beneath their community's politeness, and frame it with an editor's note, written in officialese, reporting that the diarist is now well and fully reintegrated.
Questions
What happens at the end of A Madman's Diary?
The diary breaks off with the madman hoping some children have not yet eaten human flesh and pleading, save the children. But the classical preface has already revealed the ending: he recovered from his madness and took up an official post, rejoining the very order the diary indicts.
What does the cannibalism represent in A Madman's Diary?
It is Lu Xun's metaphor for traditional Chinese society, whose Confucian ethics of hierarchy and family duty, in his view, consumed human beings. The madman finds the words eat people written between the lines of the classics preaching virtue and morality.
Why is A Madman's Diary considered the first modern Chinese story?
Published in New Youth in 1918, it was the first major work of fiction written in vernacular Chinese rather than the classical literary language, and it fused that formal revolution with a radical attack on tradition, setting the agenda for modern Chinese literature.
