When 8-year-old Su Xixi was diagnosed with terminal liver cancer, her mother was pregnant with twins and her family was in dire straits. In order not to drag down her family, she deliberately pretended to be a naughty "white-eyed wolf", throwing away the medicine her father had bought by selling blood, fighting for food, and burning awards, just to make her parents give up on her completely. After her death, her parents discovered the medical certificate and hundred-dollar bills she had hidden, and they learned the truth. Her father went to the underworld to plead for mercy, and Xixi was able to return to her family as a cat and protect her younger siblings for three years. Finally, she said goodbye in the sunshine, leaving behind a room full of family affection and endless concern.
