In the 1960s, Beijing courtyard houses. The carpenter Lin Mancang never travels through time or is reborn. He relies on his ancestral carpentry skills and a sincere heart to gain a foothold among his shrewd and calculating neighbors. A bowl of braised pork was distributed throughout the hospital, earning respect with every tenon and tenon, and impressed the grocery store girl Song Xiaoman with his sincerity. From an ordinary carpenter to an eighth-level craftsman, from the turbulent years to the spring breeze of reform, he shut up the cold-eyed people and warmed the hearts of the kind-hearted people. There is no system cheating, no quarreling and slaps in the face, only the perseverance of the craftsmen to "take their time" and the pyrotechnics and friendship slowly brewing in the courtyard. This is a warm and healing history of growth - the life of a young carpenter, harder than a fist and longer than a calculation.
