On the Bashang Plateau in Zhangbei – the closest pristine grassland to Beijing – the Anguli River, the largest inland river in north China, winds its way through a prairie, with its clear waters nurturing the land for generations. Wind turbines dot ridge lines across the grassland in a quiet dance with the sky, while cattle and sheep roam at ease. Wind rotors sway with the clouds, the river mirrors the sky – this is where the sky meets the grass, and where a prairie shares its most peaceful voice.
