Deep Sea is another original animated feature directed by Tian Xiaopeng, following Monkey King: Hero Is Back, and it represents a 3D animation project of exploratory significance for October Media. While antique stories have been popular in Chinese animation in recent years, Deep Sea takes a different approach, using unique oriental aesthetics to interpret a fantasy story set in a modern background. The film Deep Sea constructs a distinct, brand-new underwater world, telling the story of a girl who embarks on a unique life journey, seeking and searching within the mysterious underwater realm.
