A child receives a "sanfutie," or sanfu medicinal patch, in a hospital in Beijing on July 15, 2024, the first day of Sanfu, the hottest and dampest period of the year. Sanfutie, a kind of plaster using traditional Chinese medicine (TCM), has been a welcome treatment as it is believed to soothe the body and help relieve the discomfort of illnesses in winter.
