Only the River Flows (河边的错误)

Only the River Flows (河边的错误) is a 2023 Chinese crime drama film directed by Wei Shujun (魏书钧), adapted from Yu Hua's (余华) 1987 novella of the same title. Set in a 1990s Jiangnan river town, it follows police detective Ma Zhe (马哲), played by Zhu Yilong, as an investigation into murders by the river dissolves into hallucination and uncertainty rather than a solved case¹^•². The film premiered in the Un Certain Regard section of the 76th Cannes Film Festival and became an unusual commercial success for a Chinese art film, earning more than 300 million yuan at the mainland box office³^•⁴.

Narrative and style

The film keeps the detective surface but breaks its causal chain. It opens with a boy playing police officer chasing a "murderer" through a ruined building, a scene critics read as a miniature of the whole film and of Ma Zhe's predicament¹⁴. The first half follows conventional procedure, with Ma Zhe eliminating suspects through forensics, interviews, and confessions, including a celebrated deduction from a cassette tape's train whistle⁸. The second half shifts into psychological suspense: Ma Zhe's mental state deteriorates, hallucinations of the madman and violent fantasies interleave with real scenes, and the film ends without a determinate answer; the full magazine of seven bullets after Ma Zhe fires at a temple door is read as evidence that the shooting never happened⁸^•¹⁵.

Understanding the film as anti-detective rather than a failed mystery is the standard critical reading. Commentators note that the more persistently a viewer tries to identify the killer and assemble the truth, the more the film's actual design, which foregrounds irrationality and uncertainty, defeats that effort¹⁴. A narratological study identifies the film's broken narrative logic, parallel storylines, and the blurring of reality and Ma Zhe's projections as a deliberate dissolution of the detective-film model¹⁶.

The film also carries Wei's recurring meta-cinema interest. The police unit sets up its office in a shuttered movie theater, a detail absent from the novella; the fallen theater sign and a burning projector are read as images of cinema's decline, and Ma Zhe functions as both director and spectator of the fates he investigates¹⁴^•¹⁵. The 16 mm photography gives the 1990s setting its grainy period texture⁶.

The source novella

Yu Hua wrote the novella in 1987, when he was 27 and part of the avant-garde wave in Chinese fiction alongside writers such as Su Tong, Ma Yuan, and Ge Fei, a group devoted to textual experiment²^•¹¹. It appeared in the first issue of Zhongshan in 1988².

The story is built as a parody of the detective genre: it fictionalizes a murder case committed by a madman, but uses the detective framework to dismantle the genre's promise of rational resolution⁵. Critics describe it as looking like a suspense detective story while being anti-genre, anti-logic, and anti-rational, and several prominent directors, including Zhang Yimou, considered adapting it before giving up⁸. In the novel's bleak ending, the police chief arranges for Ma Zhe to be classified as a mentally ill man speaking incoherently, so that he escapes legal punishment¹². Yu Hua himself, asked what "the mistake by the river" is, answered: "I don't know either, it's just a mistake that nobody knows"¹³.

From page to screen

Dangdang Pictures acquired the rights and began preparing a film in 2017. In 2018, Wei Shujun read the novella on a producer's recommendation without any plan to direct it; in 2020 the producer asked whether he would take on the adaptation. He found the text's avant-garde quality stimulating but recognized the difficulty of translating its absurdist, even thriller-like elements, and accepted as a challenge⁶. Screenwriter Kang Chunlei described the adaptation principle: "the original novel is actually a metaphor for life through case-solving, while the film should cut life directly in"⁸.

Script work began in 2020, earlier than the shooting of Wei's Ripples of Life, and the script went through four major revisions, each in a different direction, before filming⁶. After Wei and his cinematographer read the first draft they decided to shoot on film; 16 mm stock posed processing difficulties because no large studio ran that workflow, but the problem was solved. The production used a "shoot in order" schedule to serve the film stock and the performances, and editing proceeded alongside shooting, so a cut was ready within weeks of the 1 February 2023 wrap⁶. Filming took place in Zhejiang and Nanfeng County, Jiangxi⁷.

Zhu Yilong, cast as Ma Zhe, gained 30 jin (15 kg) before shooting and then lost 20 jin as the story progressed, so that the character's physical decline would track his mental deterioration⁸. The film's first English title was "only river knows"; before release it became "only river flows", a one-word change the newspaper commentary linked to Yu Hua's view that art comes from not-knowing².

Adaptation choices

The film moves the story from the novella's 1980s to the mid-1990s and expands the secondary characters, notably the poet Wang Hong and the cross-dresser Xu Liang, whose stories are enriched relative to the novel¹⁵^•¹¹. In the film's plot, the elderly Yao-si Popo is murdered by the river; the suspects include the madman she adopted, Wang Hong and his lover Qian Ling, and Xu Liang, a man previously jailed under the "hooligan" crime who guards his cross-dressing as a secret worth dying for⁸^•¹⁴. A parallel thread follows Ma Zhe and his pregnant wife, who face a 10 percent chance that their child will have a genetic disease, a dilemma the film uses to widen the case into a question of chance and fate⁸^•¹⁷.

The film's ending diverges from the novel: Ma Zhe captures the madman in the river and receives a third-class merit citation at a ceremony in the renovated theater, an ending some critics read as possibly another fantasy¹⁴^•¹⁵. The production team also deliberately avoided some content of the novel at the script stage, with a clear sense of censorship boundaries, and avoided explicit ties to the era⁸.

Reception

The film divided critics and audiences. Praise centered on its poetic imagery, period texture, and philosophical ambition; negative reviews called the plot scattered and hard to follow, a split one commentator attributed to the film's "overloaded" metaphors¹⁸. In the China film audience satisfaction survey, all three headline indices exceeded 81, and its spread score of 84.9 ranked first among the six weekend releases surveyed in September and October 2023 and third among the year's 18 non-holiday releases¹⁰.

Commercially, the film broke RMB 300 million in China, a figure about ten times the box office of The Breaking Ice, which had been treated as a ceiling for Chinese art films; commentators credited marketing that openly billed the film as "an art work, a thousand viewers, a thousand readings," together with Zhu Yilong's star power and Yu Hua's name⁴. Internationally, it screened at festivals including Busan, Vancouver, and Chicago, won the jury prize at the Reims Polar crime film festival, and was ranked 18th in a 2023 study of Chinese films' overseas market and cultural competitiveness¹⁹^•¹⁷. Le Monde described it as a film of rain, night, solitude, and anxiety, in which the stalled police investigation becomes a confrontation with chance, destiny, and the risk inherent in existence¹⁷.
