During the reign of Renzong in the Northern Song Dynasty, Jiang Liuyan, the proprietress of "Liuyan Tofu Shop" in Suzhou, was called "Tofu Xishi" by her neighbors because of her beautiful appearance and excellent craftsmanship of traditional tofu. She adhered to the ancestral craftsmanship and had a soft personality but a strong personality. However, she was framed because she refused to be forced into marriage by a bully. The tofu shop was smashed and the stone mill was destroyed. When she was accused of being accused, she clutched the silk handkerchief with the ancestral tofu recipe. With the obsession of "protecting the craftsmanship and living a decent life", she was unexpectedly reborn and traveled to modern times.
She was reborn in the body of Chen Xueer, an orphan girl with the same name but a different surname in the old town of a second-tier city. Her parents died young and she was adopted by her selfish distant uncle and aunt. She suffered harsh treatment all year round. After she fell into the water, she was possessed by the soul of Jiang Liuyan. Living in a strange modern society, Jiang Liuyan is at a loss. She neither understands electronic products nor is familiar with modern rules. However, when she sees a tofu stall in the alley, she regains hope - she will rely on the Jiang family's ancient tofu craftsmanship to make a living in this new world.
