After being laid off, Zhao Mingxuan returns to his hometown and discovers that his grandfather, Zhao Deshun, is still making traditional stone lanterns by hand. One phoenix lantern has taken him three months to complete. A video Mingxuan casually records unexpectedly goes viral, attracting He Yingyue, a student from a design academy. Together, they combine traditional stitching techniques with LED programming to create Galaxy Lanterns and Moonshadow Lanterns, overcoming challenges at intangible cultural heritage exhibitions and innovation competitions. His grandfather entrusts him with twelve ancestral needles, and the neighbors in the alley also pick up their needles. Sixty lanterns fill the old street, illuminating the entire Lantern Alley. On the opening day of the lantern art gallery, a little girl says she wants to learn the craft. As long as the lanterns remain lit, the people will always be here.
