When a stranger steps in family care

Picture an elderly person standing alone in the lobby of a major Chinese hospital — staring at a check-in machine they've never used, a queue they can't find the end of, a payment screen that only takes a phone they don't have. For you, it's a hospital visit. For them, it's an obstacle course with no map. Now imagine a stranger walks up and plays the role of the son or daughter who isn't there — for a few hours, for a fee. Is that a solution, or a symptom of something bigger? And can family really be rented by the hour? On the show: Steve, Fei Fei & Junya
