A very low-quality animated film has become a surprise hit in China. Niu Lai is about a baby cow and a bird. Two people, possibly a mother and her son, spent five years making it.

At first, almost nobody watched the film. Then people online started saying how terrible it was. They made jokes and memes about its bad animation and strange story. Soon, many curious people wanted to see it for themselves.

Now, the film has earned millions of yuan at the box office. Some people say it is bad in every possible way - but that is exactly why people love it!
