The rimed trees in Jilin are commonly called tree hangings. In winter, the Songhua River (about 50km) keeps flowing through Jilin despite the subfreezing temperature, and the vapor rising from the surface of the river freezes when it meets the pines and willows ashore. Thus encrusted with layers upon layer of ice, the tree branches and twigs look transparent and form a spectacular crystal world that never fails to attract visitors.
