BEIJING/DALIAN The cobbled streets of Rudong County in China's Jiangsu province are lined with old one-story houses. But something is missing: young people. "What am I supposed to do when my body stops working?" lamented 81-year-old Liu Fang, who lives alone on a pension of 2,000 yuan ($306) a month.
Living nearby is Li Mei, 89. Now that walking has become difficult, she depends on her 70-year-old son to get by.
