Drawing on the lessons of his past life, he improves furniture designs and uses his exceptional mortise-and-tenon craftsmanship to create modern furniture and open up new markets. Staying true to himself, he rejects an unsuitable marriage and bravely pursues the woman he loves, Liu Hongyu. After they marry, the two establish a carpentry workshop, take on apprentices, and lead their fellow villagers in working together to build successful businesses. Seizing the opportunities of the times and working diligently, everyone uses their skills to steadily increase their income and gradually build prosperous, stable lives in the countryside.
