Elderly people ride "one-legged donkeys" in the city of Jilin, Northeast China's Jilin Province, on December 16, 2024. The "one-legged donkey" is the common name for this type of ice sled. Riders squat on a wooden board mounted on an ice skate blade or sit on a seat on top of the board and propel themselves forward using two steel spikes. Photo: VCG
