I remember a TV play in which the main characters were three girls named popcorn, light snow and jelly beans, but I forgot their names.

The name is Crazy Girl, which is a children's sitcom jointly produced by CCTV and news documentary film studio. The film is directed by and starring Tang.

The play mainly tells a series of stories about three lovely little girls, Cher, popcorn and candy, in Cher's room.
