Poor young man Lin Xiaoman lost his parents early, guarding alone the ancestral shaobing craft, making a living by setting up a stall on the small town street. A stove of charcoal fire, a piece of shaobing, originally only wanting a stable livelihood, he successively encountered peer harassment and local ruffian extortion, his business repeatedly ruined. A chance encounter, he meets the well-read Su Wan, who understands his stubbornness in guarding his original heart; the town's rich household Zhang Fugui is red-eyed over the shaobing stall's popularity, setting schemes everywhere to frame him, wanting to force Xiaoman to hand over the ancestral recipe. Lin Xiaoman has no backing, relying solely on a hand of stove-fire supreme skill, honest and kind original heart, baking shaobing that scents the entire long street. A stove of shaobing sees all human warmth and coldness, a square-inch stall witnesses market diverse states.
