A young man offered an online reward of up to 200,000 yuan (US$25,200) for those who know the whereabouts of his lost mother.

Ma Liangmei said Ma Shuxian, his mother, has not been heard from since she demanded repayment of a debt in Xiaguan of Dali, in Yunnan Province, 10 days ago.

Although his family had prepared for the worst, he hoped her mother could return home safely someday. He said he would pay 200,000 yuan to anyone who can help him find her.
