The origin of the Beitou Cooling Summer Festival dates back to the Japanese colonial period. It was one of Taiwan's early important leisure and tourism activities, where people would take trains to Beitou on summer nights to watch performances, fireworks, and enjoy delicious food. This design adopted a bird's eye view perspective and boards a time-traveling train to explore Beitou's hundred-year history, allowing everyone to enjoy the lively atmosphere of the Cooling Summer Festival.
