Thursday last week, a van navigating the narrow streets of a hardware market in China’s Foshan, Guangdong Province, struck and ran over a 2-year-old girl. The driver paused, then drove away. A surveillance camera showed that the toddler lay grievously injured for seven minutes, ignored by at least 18 passersby, while a second vehicle, a truck, ran over the child and drove on. A 57-year-old rag collector finally came to her aid.
The next day an apparently suicidal woman jumped into a lake in Hangzhou, southwest of Shanghai, and began flailing helplessly. A woman widely reported to be an American threw off her coat, swam the 20m to the drowning woman and expertly hauled her to shore. And then, seeing she was safe, the rescuer left without giving her name.
Neither episode is necessarily representative: Many Chinese do help those in dire straits, and, obviously, Americans do not always come to the rescue. But thousands of microbloggers in China have used the juxtaposition of callousness and heroism to fuel a wrenching debate over whether people in their country lack compassion, and if so, why.
