At a busy market stall a blind woman weakened by leukemia and her young daughter Tina—said to be only five or six but already chubby—buy braised pork. Tina devours the fatty portions and refuses to share; bystanders scold her as selfish and accuse the mother of neglect. An escalating scuffle and shouts of “Give it back!” draw attention. The situation turns when someone bluntly says Tina must donate bone marrow to her mother. Shoppers go from jeering to stunned, and Tina’s role as a potential donor and the mother’s treatment remain unresolved.
