Zhong Weimei, 50, cleans in front of her house in Haoling Village of Jiaoling County, Meizhou City, South China's Guangdong Province, May 22, 2013. Zhong has two sons, both attending college in the provincial capital Guangzhou, which makes life more difficult for Zhong and her husband after the rainstorm hitting Guangdong Province on May 18. With the youth attending school or working outside their hometowns, the left-behind family members are becoming even more vulnerable after natural disasters. (Xinhua/Mao Siqian)
