" The Three-Body Problem " was a Chinese science fiction that described the interaction and conflict between humans on Earth and the alien civilization. In the novel, the survival mechanism of the Three-Body People was to maintain their vitality through constant interstellar migration and interaction between stars. The Trisomatics had highly advanced technology and a complex social structure, but their living bodies did not have the ability to photosynthesize or self-replicate like the creatures on Earth. Therefore, the survival mechanism of the Three-Body People was to obtain energy and resources to maintain their vitality through continuous interstellar migration and interaction between stars. In the interstellar migration of the Three-Body People, they used a technological method called the " Three-Body Plan " to store energy and materials in special " Three-Body Balls " and then carried these " Three-Body Balls " through spaceships for interstellar migration. In the interaction between stars, the Trisoloids could use a special technology to convert their life into energy and exhale and recover the waste generated during the conversion process to maintain their own life and energy source. The survival mechanism of the Trisolan was a complicated one that relied on technology and interstellar interactions to maintain its vitality through constant interstellar migration and interactions between stars.
