Police Work Makes Time Stand Still In Only the River Flows

Detective Ma Zhe (Yilong Zhu) wanders through the frames of Wei Shujun’s period noir Only the River Flows, smoking cigarettes like carbon monoxide is actually his oxygen, almost always bedecked in his leather coat. These are the trademark symbols of a weary cop who has worked too long and seen too much. Ma Zhe’s protective outerwear doesn’t protect him at all, of course, not even against the weather; he’s often seen shivering and hugging himself for warmth in the cold rural nights he spends chasing a murderer.
Only the River Flows takes place in Banpo Town, a fictional riverside hamlet, in 1990s China. Ma Zhe, already on the cusp of being jaded when we meet him at the start of the film, is tasked with solving the murder of an elderly woman, whose dead body washes up on the shores of said river; Shujun makes hay of the “case closed!” trope, wherein the culprit is found too soon, and too easily, to satisfy the hero’s internal drive to pursue the truth and find justice. It’s the “madman” (Chunlei Kang), says Ma Zhe’s boss (Tianlai Hou) and his peers – a taciturn, behaviorally challenged man, pseudo-adopted by the elderly woman. Because he’s such an obvious subject, the audience knows that he isn’t the guy, and that the quick solution is neither about truth nor justice, but about appearances. The chief wants Ma Zhe’s investigation over and done with, wrapped with a neat little bow on top. Ma Zhe’s gut gets in the way.
It isn’t just instinct that holds up the film’s proceedings, either. It’s Ma Zhe’s impending fatherhood. Quietly, delicately, Only the River Flows uses the madman as a foil for all of the anxieties baked into every new parent-to-be. A doctor tells Ma Zhe and his wife Bai Jie (Chloe Maayan) that there’s a 10% chance that their baby will be born with a genetic defect that would stymie their cognitive growth; suddenly the madman ceases to be a mere murder suspect, and instead turns into a window for what Ma Zhe’s unborn child might be like. Immediately upon coming home from that awkward visit with the doctor, Ma Zhe practically orders Bai Jie to abort the baby.
