Based on the classic Chinese folk tale *Journey to the West* and created by the Wan brothers during World War II, *Tie Shan Gongzhu* (Princess Iron Fan) is China’s first feature‑length animated film. The story follows the Monkey King and his companions on their pilgrimage to the west. Upon reaching Fire Mountain, they discover the blaze is impassable; only a legendary iron fan can extinguish the flames. However, that fan belongs to Princess Iron Fan, and she is unwilling to lend it to them.
