The first Chinese animated film to put Zhu Bajie at the center, the story focuses on the character's growth and change. Where traditional heroes of Chinese animation are often rebellious, Zhu Bajie has long been a controversial, much-discussed figure. Here he is gluttonous, lazy, and a little selfish, yet he holds to his own limits and principles, a flawed man with a warm heart. The film also traces his romance with Sister Egg of Yunzhan Cave on Fuling Mountain, his first love, a bond that brings out his loyalty and tenderness. Their encounter plays like beauty and the beast, lovely but brief, and the sincerity of their love brings tears.
