As night falls, Desheng – a small village on the Bashang Grassland in Zhangbei County, Hebei Province – portrays a passionate painting with fire. The bonfire blazes as people sing and dance, making quiet wishes in the warm glow. Fireworks explode, slashing through the prairie night. By the grill, flames leap over sizzling skewers. Then comes the grand finale: "Dashuhua," a national intangible cultural heritage, as molten iron heated to 1,600°C is hurled into the air, showering the darkness with countless sparks like a meteor rain. Bonfires, fireworks, sparks and smiling faces – Desheng's night speaks the oldest language of fire, telling tales of reunion and heartfelt wishes.
