Fang Zhiyuan, an art academy graduate, arrives in Xinan Village to renovate an abandoned old oil mill into a workshop for educational and cultural experiences. There, he unexpectedly meets Shen Yu, who is dedicated to preserving the traditional craft of fish lantern making. Together, they promote the art of fish lantern craftsmanship, overcoming challenges involving material shortages and the realities of online popularity and cultural preservation. They establish free hands-on classes for ordinary people and visually impaired participants. Staying true to the spirit of handmade craftsmanship, they bring Xinan's fish lantern tradition, which was on the verge of disappearing from everyday life, back to the countryside, ensuring it can be passed down from generation to generation.
