Twenty-Four Hours () is a Chinese outdoor reality show which started in 2016 on Zhejiang Television. It is a large-scale outdoor game-variety show where cast members attempt to complete missions to find a mysterious item. It features an overarching plot during each season. In 2018, it ranked among the "Top 3 Chinese Competition Programs".
Within 24 hours, two teams must uncover the "master of the star" and the hidden star by completing tasks. Secretly, at least one member is assigned as the "master" with a separate mission. If the team correctly identifies the master, they earn a star; if not, the master earns two.
Time-space sailors traveled the world to retrieve the scattered tokens of the "Goddess of the Sea." The captain system was removed, and before each mission, one or more sailors were secretly assigned special identities with tasks to complete within 24 hours.
Inspired by Zheng He's voyages, seven sailors retraced the Maritime Silk Road to find scattered stars and escape the eye of the storm. Led by captains Jimmy Lin and Shawn Yue, members secretly took on star-owner roles with hidden tasks to complete within 24 hours.
