Stars go to the cinema to promote what is usually called a "movie roadshow". Film roadshow refers to a series of publicity activities organized by film producers or propagandists before or during the film release. These activities usually include stars going to various cinemas to publicize, interacting with the audience, signing autographs, taking photos and so on. Through the film roadshow, the stars can personally introduce the content and characteristics of the film to the audience, increase the expectations and enthusiasm of the audience, and improve the popularity and box office of the film. At the same time, it is also a good opportunity for stars to show their image and charm and interact with fans.
