New bride Liu Chunmei marries into the Zhang family. Seeing her mother-in-law, Wang Xiuzhen, constantly bullied by her younger sister-in-law and dragged down by her younger brother-in-law, she resolutely steps forward to protect her. She takes her dejected mother-in-law to revive their ancestral tofu-making craft, starting from a small stall all the way to opening a shop in town. With mother-in-law and daughter-in-law of one heart, relying on hard work and duty to prop up a whole sky for the family, she also helps her mother-in-law, who has endured humiliation for half a lifetime, straighten her back once again.
