Zhou Guangsu and her husband Xiao Ming have been living in a cave for about 50 years in Shuangdong village, Liupanshui, southwest China's Guizhou province. In the cave, Zhou gave birth to seven children who built new houses elsewhere after they got married. Two years ago, Zhou's husband left the cave to live with his youngest son. Although she was left alone, she seldom felt lonely as seniors nearby came to her cave and chatted with her.(Photo/Chinanews.com)
