Amid the wave of reform and opening up in the 1980s, craftsman Zhou Musheng remains committed to the traditional mortise-and-tenon craft. Unwilling to cut corners and deceive customers with shoddy workmanship, he resolutely leaves his old workshop. With the quiet support of his wife, Li Xiulan, and the steadfast companionship of his fellow craftsmen, he struggles to get started with a street stall by the bridge. Facing rumors, criticism, exclusion from competitors, and the disruption brought by modern machinery, he stays true to the principles of a craftsman, valuing both skill and integrity. Overcoming one real-life hardship after another, he carries on traditional woodworking techniques and forges a path of perseverance for ordinary people amid the sweeping tide of the times.
