The Mother Behind Niu Lai: How Sun Lifang Turned Five Years into a Song

Most viral films have a marketing team behind the noise. Niu Lai (牛来) had a mother. The 86 minute animated feature that stunned China's 2026 box office with more than 59 million yuan from a near zero budget was built by two people: director Xin Yumeng and his mother, Sun Lifang. Her role went far beyond moral support, and the part audiences remember most is a song.

Sun Lifang was in her early sixties and retired from a state owned enterprise when her son, then in his early thirties, announced he would make a theatrical animated film. Xin Yumeng had trained in art landscape design and run a small decoration company in Dalian. He had no animation background, no team, and no plan to hire one. His mother did not tell him to be realistic. She learned screenwriting from scratch, voiced the female characters, and then wrote, composed, and sang the film's closing song.

That song, After the Rain (雨后轻风有香), has become the emotional center of the whole project. Sun Lifang wrote the lyrics, scored the melody, and recorded the vocal herself on aging equipment. The music carries a faint Soviet era folk warmth, built from plain images of grass waves, soil, and seeds. What stops listeners cold is a quiet trick in the words. The line "when does the rain turn soft, when does the sprout break ground" hides the two characters of her son's name, Yu Meng. She slipped her child's name into a song about growing through storms, an audible letter from a mother who spent five years learning skills she never needed before.

Viewers who laughed at the crude 3D models often fell quiet for the credits. Music critic Ai Diren called maternal love the film's single biggest production investment. Online comments call the track "worth 100 million" and note that people stayed in their seats until it finished. The contrast is the point: the visuals are an amateur's best effort, but the song is a parent's whole heart. For readers tracking Chinese animated film culture, this is the detail that travels best across languages.

The track has taken on a life beyond the film. Fans have posted covers, and at least one Russian language adaptation has surfaced online. A song written by a retired mother on old equipment is now the most shared piece of the entire project, outrunning the cartoon that spawned it. Where the animation divides viewers, the melody unites them.

The family's life off screen reads like a fable. Their registered address is an old walk up building in Dalian where a neighbor said he had not exchanged a word with the director in six years. On the door, someone had pasted four characters meaning "may success arrive at once." The mother who rarely spoke in public became, after the film's breakout, the figure many cited when they called Niu Lai a story about a deeply loved child.

Not everyone reads the relationship as healthy. One long essay noted the Niu Lai mother son bond is intense and sealed off, with almost no contact outside the two of them, and warned against romanticizing isolation. That tension is real. What is hard to dispute is the labor. A woman past retirement age taught herself three new crafts so her son's dream could reach a theater screen. The film's highest cost was never the computer. It was the years.

The closing song explains why a cartoon with broken models outearned projects with a hundred times its budget. Sun Lifang did not make the animation look good. She made the audience care, which is the harder job. When the lights come up, people do not talk about the polygons. They talk about the mother who learned to sing.
