This work is produced with AI assistance. Mu Xiaodiao returns to her hometown to participate in the ancestral hall restoration, hoping to repair the damaged flower windows. Under the guidance of Old Man Diao, she learns old patterns, wood selection, sample tracing, and carving rules, and formulates a dual-line plan with Su Jiutang combining traditional restoration and new applications. Facing problems such as trial carving and wood deformation, she repeatedly adjusts, insists on completing important flower windows according to the old manual, and also explores expressions suitable for new spaces. After the ancestral hall restoration is completed, the pattern manual is exhibited, and tourists participate to understand wood carving. Old Man Diao hands the chisel to Mu Xiaodiao, and the flower windows illuminate the old hall again, passing down the craftsmanship.
