Su Wan was originally the technical backbone of the Red Star Slaughterhouse/Meat Factory, specializing in the processing and marinating of pork and sheep kidneys. Three months after her wedding, her husband died in the line of duty in an accident at the factory, and she became a "young widow" in the family home. She looks gentle and delicate, but in fact has a fierce temper and a bright mind. She has the secret recipe of braised kidneys and the skill of Northeastern sauce meat passed down from her ancestors. She also hides her husband's pension and the exclusive recipe of braised meat. She has become the coveted target of everyone in the family.
