The country of Sam in the novel "The Three-Body Problem" was often depicted as a fictional country representing American values and culture. Although the name of the State of Sam originated from a state in the United States, it did not actually exist. It was just a fictional character and symbol in the novel. In the novel, America was regarded as a dystopian fable, expressing people's pursuit of ideals, freedom, and technology, and their concerns about the injustice, tyranny, and restrictions in reality.
