Su Huifang, a renowned medicinal cuisine chef, gave up her career and moved to the city to care for her granddaughter for five years for the sake of her daughter, Lin Jiao. Every day, she woke up early to prepare medicinal meals and take care of the household. She even paid off 500,000 yuan in mortgage debt for her daughter's family and contributed another 180,000 yuan toward their living expenses. Just as her granddaughter started elementary school, Lin Jiao decided to make room for her mother-in-law's walk-in closet. She forced her own mother to sign an IOU for 108,000 yuan in accommodation fees and demanded that she transfer ownership of her old house to settle the debt.
