This work was produced with AI assistance. Because his old shop was quiet, Zhou Chengqi took his ancestral old hammer into the city to grind and make a living, yet he always insisted on hand-forging knives. Under the guidance of an old master and with the trial support of Chef Chen, he repeatedly improved kitchen knives and returned home to reopen his shop. When Chef Chen was in a competition, the knife he made suddenly broke; he hurried back to the shop to fetch a new knife, helping Chef Chen complete the competition and win an award. Thereafter, orders gradually increased, colleague Xiao Lin came to apprentice, and his father joined to tend the fire and help out. Together they nurtured apprentices, improved knife types, and insisted on quality, letting the old shop's hearth fire reignite and finding a way out for traditional craftsmanship.
