Flower grower Ruz and his wife Tajinisa weigh rose petals used for making rose sauce at a village in Hotan, northwest China's Xinjiang Uygur autonomous region, on June 6, 2018. Roses are now in the end phase of their life cycle, but Ruz can still harvest more than five kilograms of fresh rose petals every two or three days. People here specialize in making rose sauce from these fragrant flowers, which has become a vital source of income for local people.[Photo/Xinhua]
