Rongchang Grass linen is a traditional Chinese handicraft with a rich history. It is a kind of cloth made of ramie purely by hand, and famous for its soft, thin, flat texture and fine quality. Because this cloth usually keeps the body cool in the hot summer, it is also named Xiabu (literally meaning summer cloth). With comprehensive epidemic prevention measures, Xiabu making industries here have resumed production. [Photo/Xinhua]
