In the Later Heaven Bagua used in classical feng shui, North is governed by the trigram Kan (坎), the trigram of water in motion — a flowing stream rather than a still lake. Its element is water, its season is winter, its colour is deep blue or black, and its life area is career and life path.
North is the most yin of the eight directions. Its energy is reflective, slow-moving, and tends toward depth rather than visibility. This makes it ideal for quiet productive functions — a study, a home office focused on thinking work, a master bedroom for stable rest — and unsuitable for high-yang functions like a kitchen (whose fire clashes with water) or a children’s play space (which needs more yang stimulation).
The element governing North is water, which is supported by metal (productive cycle: metal generates water) and weakened by earth (controlling cycle: earth dams water). Wood drains water (water nourishes wood), and fire clashes directly with water. These element relationships govern which rooms thrive in the North sector and which struggle.
In Eight Mansions feng shui, North is auspicious for people in the East Life Group (Kua 1, 3, 4, 9) and inauspicious for the West Life Group (Kua 2, 5, 6, 7, 8). For East Life Group people, North is the Fu Wei (伏位) sector for Kua 1, providing stable steady support — one of the four classically auspicious directions to face for daily activities.
