Young entrepreneur Zheng Haoxuan suffered a career collapse and was burdened with a debt of 300,000 yuan, and fell into a desperate situation in life. I accidentally opened the wooden box left by my grandfather and obtained the "Craftsman's Notes", ancestral carving tools and a mysterious wooden sign that can see the "Craftsman's Soul". Relying on his intangible cultural heritage restoration skills and his craftsmanship ability, he took on antique restoration orders and became involved in the mystery of the "Secret Records of Tiangong" behind the armchairs of the Ming Dynasty. He encountered debt collectors, craftsman organizations, cultural relic dealers and other forces competing for it. In the process of guarding intangible cultural heritage skills and uncovering family secrets, Zheng Haoxuan used his ingenuity to match his original intention, counterattacked in desperate situations, used his craftsmanship to rewrite his destiny, and protected the inheritance of the craftsmanship.
