A story of master braiser Zhou Jianguo and his apprentice Chen Lei turning against each other over a shop lease. Urged on by his family, the apprentice takes over the shop, betrays the craft's integrity, and chases profit alone—only to run the business into ruin. Zhou Jianguo reopens a new shop with his starter broth, staying true to craftsmanship and building a thriving braised-meat business. Through a single pot of old broth, the story shows that craftsmanship means staying true, and that behind any craft lie a person's integrity and bottom line.
