Synopsis：Never has a common man like Ma Jianguo grown up alongside the Republic itself. This film is deeply grounded in everyday life—funny, witty, and heartwarming enough to bring tears—telling a story set in Beijing. Born on October 1, 1949, Ma Jianguo comes from a family of lantern craftsmen, carrying on an authentic trade passed down through generations. At first, he has no love for this craft, always dreaming of other grand ambitions. Like many in their twenties and thirties, he experiences youthful fights, conflicts with his parents, a secret crush on a kind-hearted woman, and a single-minded determination to get into college. After all kinds of trials, Ma Jianguo eventually comes to love the old lantern-making tradition. Representing the older generation, he is upright and steadfast, preserving the traditional craft of handmade lanterns while upholding the noble virtues of traditional culture. His grandson, Ma Wuliu, as the younger generation, moves from rejection and misunderstanding to gradual understanding and recognition, undergoing a crucial transformation in life. The bond between grandfather and grandson grows deeper and more harmonious.
