Ratatouille is the name of the Provence vegetable chowder made by Xiaomi, which shocked the critics. Ratatouille is not an English name, but a French word. This is a compound noun. Ratatouille means "by hand" and touille means "stirring"). It is appropriate to use this key dish name, which is related to the future of the restaurant and the protagonist, as a signboard, and also as the title of the film. Coincidentally, the name of the dish at the beginning of rata means English mouse:)
