"Minimalistic and abstract poster for an Asian film similar to 'Tom Sawyer and Huckleberry Finn.' Focus on key symbolic elements or iconic imagery that reflects themes of adventure and friendship without directly depicting main characters or scenes. Use a limited color palette and include subtle visual clues hinting at cultural and emotional aspects of the film. Create a mysterious atmosphere with a clean and sleek design, emphasizing simplicity in forms and lines. The design should be modern and visually striking, with a touch of intrigue, aiming to spark curiosity and encourage viewers to guess the film through indirect hints."
