On a stormy night, Huang Xiaoyao's four-year-old son suffers a febrile seizure. She rushes into a mahjong parlor, flips a table, and grabs her ex-husband's wages to pay for emergency care, finally tearing their broken marriage apart. Her former in-laws forge 100,000 yuan in marital debt and fight for custody. Her ex-husband is addicted to gambling, owes over 100,000 yuan in child support, and she is left to face her indifferent older sister and neighborhood gossip. Overnight, she is plunged into a desperate situation, surrounded on all sides. She returns to her accounting studies, working odd jobs while studying hard to earn her intermediate qualification and CPA credentials. Armed with her ledgers and complete evidence, she repeatedly fights off harassment from her former in-laws and their malicious lawsuits. Over eighteen years of struggle, she endures her child's serious illness, her father's coronary heart disease, her ex-husband's online harassment and false rumors, and malicious attacks from her peers. She raises her son alone as he pursues his love of art and soccer, while also founding a financial and tax consultancy and opening a public-service support class for single parents. She goes from protecting her child in desperation with little more than a fiery temper to establishing herself through hard-won expertise. She wins every custody and debt case, repays every personal favor, and helps countless women facing similar hardships. This story lays bare the painful struggles of single mothers and offers a simple truth: a burst of temper may get you through a crisis, but real expertise is what gives you security for life.
