In 1951, 16-year-old Liu met 26-year-old Xu Chaoqing and fell in love her. She was a widow with four children and in the remote village. At that time it was taboo for a man to marry an older woman, let alone a widow. However, Liu had made up his mind and the whole family moved to a secluded house in the mountains to avoid criticism and discrimination from villagers. In 2007, Liu passed away and Xu moved in with her sons, grieved and eventually died on Oct. 30, 2012. Her children buried her with Liu, according to Xu's wishes.
