I transfer 5,000 yuan to my grandma every month for living expenses, but she fainted at the village entrance due to severe malnutrition. When I got home, I saw moldy mooncakes and watery porridge with a white film on top. My grandma, with her withered hands, clutched the corner of her clothes and said all the money was spent. The empty rice container and the doctor's warning pierced my heart. I am determined to calmly investigate where the 5,000 yuan really went and protect my dearest relative.
