In Hotan, Northwest China’s Xinjiang Uygur Autonomous Region, the tradition of using usma grass to nourish and tint eyebrows has been passed down for more than two centuries. In 2013, it was officially recognized as an intangible cultural heritage of Xinjiang.

Today, Zak, a young man from Hotan born after 2000, is using videos and livestreams to introduce this age-old beauty tradition to audiences across China, bringing a plant long cherished for its hair-nourishing qualities to a new generation. (Wei Chenxi)
