Su Yanzhou, heir to Yunxi's colored-lantern tradition, keeps his old lantern workshop alive—yet the lantern fair is canceled and orders are returned. Cultural creative planner Lin Wantang arrives with fresh ideas: detachable bamboo joints and hands-on classes to bring lantern art into everyday life. Su fears the craft will lose its soul; Lin fears it will be lost forever. From clashes to collaboration, they test again and again in the old bridge market and bamboo-shadow workshop. At last, on the river lantern festival night, a starry lantern corridor lights up, and traditional lantern art is seen by more people through both tradition and innovation. A positive-energy story of intangible heritage, craftsmanship, and rebirth.
