Fengshui ("wind and water") is the Chinese art of siting tombs, houses, temples and whole cities in harmony with the flow of qi across a landscape of hills, water and the cardinal directions. Classic doctrine favours a south-facing site sheltered by higher ground to the north, with watercourses to the front, and aligns buildings on a north-south axis. From burial siting it expanded into a comprehensive geomancy applied to settlement layout and capital planning. It supplied the orientation logic behind the central axis and four-sided enclosure of Chinese cities and courtyard houses.
Fengshui furnished a cosmological rationale for urban orientation and siting that shaped the axis, enclosure and aspect of Chinese settlements for two millennia and still informs property practice across East Asia.
