Geneva (AFP) - Mrs Fang, Chinese director Wang Bing's documentary about a family waiting to say goodbye to their elderly Alzheimer's-stricken mother, won the top prize at the Locarno film festival in Switzerland on Saturday.
The film tells the moving end-of-life story of Fang Xiuying, a farmer who has been struggling with the disease for eight years.
After a stay at a nursing home, her family brings her home, and the film focuses on their final days together before her death in 2016.
Wang is counted among China's foremost documentary film makers. French director Olivier Assayas served on this year's Locarno jury.
