Su Wanwan has been married for three years, practicing an AA system with her husband Lin Feng. When her father had surgery and her mother came to stay and care for her for seventeen days, Lin Feng actually calculated a bill of over 6,000 yuan. Soon after, her mother-in-law broke her leg and came home to recuperate, and Su Wanwan charged item by item using the exact same standard. Unable to bear the heavy burden, Lin Feng secretly sold the gold necklace left behind by his wife's maternal grandmother. Su Wanwan endured and gathered evidence, legally reclaiming her rightful share of property, and ultimately resolutely divorced, growing independently, and welcoming a new life.
