A boy in a small Chinese town during the 1930s refuses to accept that his mother is gone. He clings to a promise she made before disappearing: that she would return for him. Convinced she's still out there somewhere, he sets out into the streets to search, determined to find her and bring her home. The world around him is fractured and uncertain. The decade tears at everything with war and upheaval, yet Yueyue moves through it with the stubborn hope only a child can carry. Each person he encounters, each corner he explores, becomes part of his journey. His search becomes both literal and internal, a way of refusing to let go of the one person who mattered most. This is a quiet film about loss and longing, about the gap between what we're told and what we choose to believe. It sits with the weight of memory and separation without looking away. If you connect with intimate character studies set against historical backdrops, or stories about how children process grief, this one stays with you long after it ends.
