Li Fenglan, the mother-in-law, became addicted to health products and various fraud traps due to her greed for small gains, which led the family into a crisis. Li Fenglan credulously believed that the health product "Snow Lotus Anti-Toxicity Pill" could cure all diseases. Despite the opposition of her daughter-in-law Qi Xuan, she fed it to her grandson Chen Tiantian before his surgery, resulting in massive postoperative bleeding and organ failure. Although Tiantian was saved after emergency treatment, he was left with sequelae that caused him to have a life expectancy of less than 30 years.
