Niu Lai, an 86-minute animation about a calf and a skylark, has become an unexpected sleeper hit at the Chinese box office.
Created over five years by mother-and-son duo Xin Yumeng and Sun Lifang, the film initially flopped, earning just 7,700 yuan in its first ten days.
Online mockery of the film's crude visual quality triggered a viral meme, driving curious audiences to cinemas and pushing revenues past 14.9 million yuan.
