The Amazing Chan and the Chan Clan is an American animated television series produced by Hanna-Barbera Productions. The show was loosely based on the Charlie Chan series of mystery novels and films, which began with the 1925 novel The House Without a Key. Throughout the series, legendary Chinese sleuth Charlie Chan is both impeded and assisted by his family of ten children and their dog Chu Chu. The family travels around the world in the Chan Van, a vehicle built by teenage genius Alan Chan, which can transform itself with the push of a button.
