?Coco,? a movie about a Mexican boy who longs to be a musician, is more popular in China than in Mexico?s neighbor, the United States. The reason may be China?s respect for the dead. ?Coco? has grossed $154 million in China over four weekends, compared to $150.7 million in the U.S. ?Coco? is by far Pixar?s biggest hit ever in China, nearly quadrupling the $38 million made by ?Finding Dory? last year.
