Niu Lai Creators: Director Xin Yumeng and Sun Lifang

Public credits and media reports identify Xin Yumeng (信雨萌) as director and Sun Lifang (孙丽芳) as screenwriter, with the pair covering many production tasks. Their relationship and exact budget need careful attribution.

The publicly reported core creators of Niu Lai are Xin Yumeng (信雨萌), credited as director, and Sun Lifang (孙丽芳), credited as screenwriter. Dated reports and end-credit observations assign Xin Yumeng several additional jobs, including modeling, animation, editing, producing, and voice work, while Sun Lifang is credited with writing and voice work. The relationship, production length, and budget require more careful wording than a viral headline often gives them.

Who is the Niu Lai director?

Xin Yumeng, also written as Yumeng Xin when a Chinese name is reversed for English search, is identified in the public credit and media record as the director of Niu Lai. The same record assigns modeling, animation, editing, producing, and voice-related work to Xin Yumeng. This is why searches for “Niu Lai director,” “Xin Yumeng,” and “Yumeng Xin” lead to the same creator topic rather than three different people.

Sun Lifang is identified as the screenwriter and is also reported as contributing voice work. The role split does not mean that every task has a separate, independently published production log. It means the available credits and reports attribute a large share of the visible production work to these two names.

How did two creators cover so much work?

The Paper and Beijing News reports in the source snapshot reviewed on August 16, 2026 describe a production without the usual large animation pipeline, external departments, or independent rendering team. Simplified modeling, a long project timeline, and limited equipment are part of the explanation offered by those reports. They help explain how a very small core team could finish a feature-length project, but they do not provide a complete accounting of every person, tool, or outsourced task.

The phrase “made by two people” is therefore useful as a description of the reported core workload, not as proof that no other person ever contributed. A small credited team and a fully isolated production are different claims.

Are Xin Yumeng and Sun Lifang mother and son?

Several media reports and statements attributed to people close to the creators describe the pair as mother and son. That relationship is part of the public story around Niu Lai, but the source record is mainly reported speech rather than an independent interview conducted by this site. The careful formulation is “media reports describe them as mother and son,” not “the site independently verified their family relationship.”

The same distinction applies to “handmade” or “purely hand-produced” language. It captures the unusual concentration of jobs, but it can erase the equipment, review, distribution, and other work required for a theatrical release. Readers should treat it as an explanatory media phrase rather than a formal production credit.

Was Niu Lai made in three years or five years?

The public discussion includes both three-year and five-year descriptions. The more stable timeline in the source material is that the screenplay was filed in 2021, the film had public-release approval by 2024, and the theatrical release came on August 5, 2026. That shows a project spanning several years from filing to release. It does not establish that every day in that interval was active animation work.

Until the creators publish a production diary with dates, “the project crossed several years” is safer than presenting exactly three or exactly five years as a confirmed concentrated production period.

What was the Niu Lai budget?

No authoritative public source in the reviewed material gives a verified production-budget figure. Reports discuss limited equipment and a small company background, but those observations cannot be converted into a cost estimate. Claims such as “the film cost only RMB 7,000” should remain unverified unless a primary financial record is published.

The box office also cannot prove the budget or profitability. Use the Niu Lai box-office timeline for dated gross reports, and read the plot and ending page for the film itself. For the broader cultural event, see why Niu Lai went viral.
